Episode 169
[RERUN] Toothpaste, Dentistry and Plastics
Episode Summary: This conversation is a rerun of an episode we initially published in July 2022. We talked about how taking care of our teeth can impact the environment and how we can do better
Jenn, Leekei and Rob discussed the environmental impact of taking care of our teeth as well as plastics contained in toothpaste, dental floss and toothbrushes and alternative solutions to reduce the daily release of microplastics in waterways.
Rob shared his experience of implementing change in his dental practice by using more sustainable equipment and consumables, and advocacy

Hi, I'm leaky.
2
:JENN: Hi, I'm Jen.
3
:Leekei: Hi, Jen.
4
:What are we going to talk about today?
5
:JENN: We're going to talk about
toothbrushes and dental floss.
6
:And actually, I think we should
talk about the industry of
7
:dentistry and the planet today.
8
:Leekei: And so our entry point is plastic.
9
:JENN: Yes,
10
:absolutely.
11
:And all the plastics, and we have
a special guest with us today.
12
:Who's not really a guest because he's part
of the carbon Almanac and doing a whole
13
:bunch of stuff behind the scenes, but
he happens to be an expert in this area.
14
:So let's welcome, Rob,
15
:ROB: Hi, Hi.
16
:JENN: should we say Dr.
17
:Rob?
18
:ROB: It can be Dr.
19
:Rob.
20
:Yeah.
21
:JENN: Tell us what you do, Rob.
22
:, ROB: I'm an orthodontist.
23
:Uh, so I treat, , adults and children.
24
:So my main role is, uh,
straightening teeth.
25
:We also get involved with,
uh, tooth whitening as well.
26
:And I've been an orthodontist since 1997.
27
:So it's my 25th anniversary this year.
28
:JENN: Congrats.
29
:So
30
:what is the biggest thing that
you're noticing and what is your
31
:pet peeve in this whole thing?
32
:ROB: I suppose one of my things that
worries me most , is the toothbrush
33
:issue because people are changing their
toothbrush on a, quite a regular basis.
34
:, , some people are changing their
toothbrush every three months, every
35
:six months and, that's needed.
36
:So there's a need for people
to keep , their mouth healthy.
37
:And so that's my prime role, but,
uh, I feel terrible that, uh, this.
38
:So many toothbrushes
are made outta plastic.
39
:That's the bristles , and the handles.
40
:And there are, there
are alternatives there.
41
:, and so bamboo is one of the, , materials
that's used a lot in toothbrushes.
42
:And I, I would like to have
some part in changing that.
43
:Uh, but having invested in some
bamboo toothbrushes, there isn't
44
:really that much of a market for them.
45
:So people.
46
:Necessarily buying them.
47
:So we do point it out.
48
:And, we mention it to our patients and
slowly people are starting , to buy them.
49
:But, if you buy toothbrushes,
even if you buy bamboo ones, you
50
:still have to be careful because.
51
:If you want to completely get
rid of plastics, sometimes the
52
:bristles are still made of plastic,
even with the BR bamboo handles.
53
:And sometimes the, the bristles
are made out of animal hair as well.
54
:So that's another thing , to look out
for, and it's not always made that
55
:obvious in the product information.
56
:So, , again at the moment, I think
that, , there, there are companies
57
:doing these things, but until it
really scales up, uh, we have a
58
:problem of supply and demand really.
59
:JENN: I always use bamboo toothbrushes.
60
:And I also use that dental lace
that you, you pop the refill
61
:into a glass, uh, little.
62
:Holder that has the,
the cutter for the lace.
63
:and so when I go to the dentist,
I always, say, no thanks when they
64
:try to give me stuff at the end
of the appointment, because I.
65
:Getting it myself, but it's a lot
more expensive, you know, when you
66
:can get a free toothbrush and dental
floss from the dentist at your six
67
:month or eight month appointment,
, it's more expensive to spend $5 or
68
:whatever it is on a bamboo toothbrush.
69
:And then the dental lace and the dental
lace is also, it breaks really easily.
70
:So there are definitely some
areas that could be improved in
71
:the, the natural replacements.
72
:I think.
73
:ROB: And I, I think that if patients
want to do something that they
74
:can talk to their dentist and
say, why don't you provide these?
75
:And just put that bit of information
inside the dentist's head to make
76
:them start thinking about, Hmm, maybe
I should look and see what is there,
77
:but it comes down again to, um, a
supply and demand thing that if.
78
:I was actually offered by a
company to have some bamboo
79
:brushes at one pound each, but I
would have to buy 10,000 of them.
80
:and storage wise,
81
:we could realize stuck for years and
years if we weren't selling them.
82
:So it just, it, it just didn't
make sense to do that, but, uh,
83
:we are waiting and I think it it's
a reasonable thing at some stage.
84
:If there is the market.
85
:Leekei: But what about the,
the regulations because , it's
86
:a non fact that it's made of
plastic and it's not recyclable.
87
:And so is there any lobby that
works towards, , making it illegal?
88
:ROB: Well, one thing that is happening is
that, uh, Colgate or a company in the UK
89
:at the moment are they, they do something
where you can have bins and people will
90
:put the toothbrushes into the bins and
then they're taken away and made into a
91
:park bench or something of that, kind.
92
:And I think that could be played with.
93
:, this park bench has been made
by recycled toothbrushes.
94
:And you're sitting amongst nature.
95
:That makes a lot of sense.
96
:Cause it's reminding you of, the
environment at the same time.
97
:And one of the other things we've
tried is to get one of these
98
:recycling bins in our practice.
99
:But, uh, we were told because there were.
100
:Council, I think there was a council,
, involvement with it that, uh, they'd
101
:already got one in their local library.
102
:And so we couldn't have one . So again,
we we're in a very good place, you
103
:know, we could actually make something
of it, see patients on a regular basis.
104
:And so again, it's um, if companies
are prepared, then I'm sure if, um,
105
:dentists become more aware of this
issue, uh, that they can be a, a part
106
:of the solution, but it's taking time.
107
:I think that's the.
108
:Leekei: Is there an alt to toothbrushes
because I saw, I see ads where,
109
:you know, you can like some gums
or something that you can just
110
:chew without having to brush a tip.
111
:that, does it work?
112
:ROB: It probably doesn't
work quite so well.
113
:So it, it could be that you are taking,
\ , an element of risk and any of these new
114
:niche areas, uh, are often market led.
115
:So a company will release them in advance
of the responsible bodies, takes years
116
:for people to do research on things.
117
:So they keep chopping and changing
to make it difficult for research to
118
:reveal whether things work or not.
119
:So, uh, I, I think that one, one area.
120
:That I quite like is moving
towards, , toothpaste tablets.
121
:They're not really toothpaste, but
they're a tablet instead of, , a paste.
122
:Um, , the big problem with
toothpastes is that often the.
123
:The toothpaste itself, the tube
itself is made outta a combination.
124
:Sometimes plastics try to move away
from metals cuz the combination
125
:of metal and plastic makes them
even more difficult to recycle.
126
:if you've got plastics,
then rolling them up.
127
:There's some companies actually
even will try to design it.
128
:So that 10% of the toothpaste is
left in the tube that you can't get.
129
:BEC that 10% is wasted and all of these,
uh, toothpastes have got microplastics in.
130
:So we're putting these microplastics
in our mouth, which help to
131
:scour the surface of the enamel.
132
:But we then spit that into, , the.
133
:Water supply goes off, down, into
the water waste, , and, uh, of
134
:course into our rivers and streams.
135
:So , that's quite a worrying thing.
136
:And I think that if we can move
towards other forms of, um, perhaps
137
:toothpaste that don't have microplastics
in or, uh, toothpaste tablets, and
138
:that could be a good move forward,
139
:JENN: I was, I was shocked to learn
that not that long ago, that there were
140
:microplastics right in the toothpaste
141
:and we ordered some tooth
tablets, but they had to come
142
:from the UK and we're in Canada.
143
:It took forever to get this bottle, but
it was a great big bottle and it it's
144
:still going two years later or something,
but You know, then there's the whole
145
:question of, , you know, does it work?
146
:Are you supposed to have fluoride,
, like there's all those questions and
147
:then, um, we've tried the tooth PA
like the pace that you can buy in
148
:the health food store that's made
with clay and things like that.
149
:And, uh, and that works, but it,
again, it's more expensive than the
150
:ones that That are mass produced.
151
:That aren't good for the planet, right?
152
:It's the same old issue.
153
:ROB: yeah.
154
:And I think the, the they're small
companies very often, so their margins are
155
:much more difficult to, , , to achieve.
156
:And as a result, they're trying
to work around that by creating a
157
:subscription model for their business.
158
:But I contacted, um, a tablet company
a few weeks back, uh, Interested
159
:to find out what they offered
to the dental profession, dental
160
:professionals, dental practices.
161
:And I just haven't had a response back
and I've had that happen a few times
162
:over the years just don't respond.
163
:So I think they're clearly wanting
to go direct to the consumer
164
:because that's where they feel
, the proper profit is for them.
165
:Leekei: Yeah, but also
because, um, there's small
166
:companies and there's startups.
167
:And so this is something I see
a lot that small companies, the
168
:founders spend a lot of time, energy
on developing their product and
169
:don't really take care of sales.
170
:, there's different sales
channels they can get to.
171
:So I don't think it's because
they are not very interested.
172
:Maybe it's because they are
not very well organized as
173
:well.
174
:ROB: Yeah, yeah.
175
:That, I think that's absolutely right.
176
:Yeah.
177
:, and , some of the earlier tablets
didn't have fluoride at all.
178
:And I.
179
:I always feel that fluoride , is
a good thing , to have in
180
:a, a tooth cleaning product.
181
:And, um, if people are worried
about fluoride, I often
182
:say, well, do you drink tea?
183
:Cause most people do.
184
:, the average tea leaf
contains, , a thousand parts.
185
:Perme fluoride, just
the same as toothpaste.
186
:So there's a huge
amount of fluoride in it.
187
:It does favorably suck up fluoride.
188
:And although that isn't available
fluoride to your mouth, when you drink
189
:tea, , there is a reasonable amount in
terms of the volume you're drinking.
190
:So you.
191
:Could probably end up taking in more
fluoride per year by drinking tea
192
:than you would buy, using toothpaste
193
:JENN: There you go, you
learn something every day.
194
:I didn't know that
195
:Leekei: Yeah.
196
:But , since you, mentioned that
there's small plastic, like small
197
:PLA pieces of plastic in toothpaste.
198
:I looked at , all my toothpaste tube
and none of them mentioned that.
199
:So can you confirm that it's an old
200
:toothpaste that we used.
201
:ROB: There's usually something like,
um, polyethylene or something of those,
202
:those sorts of, uh, words that are used.
203
:So it'll be a chemical name that's
used, so they won't say microplastics.
204
:Um, but it'll be the word if you
see the word poly and, uh, YL,
205
:those are telling you that there's
some kind of plastic ingredient in.
206
:Leekei: But that's,
207
:that's really bad because there's there
no way that microplastic can be recycled.
208
:ROB: it's a little like, uh, people
use the term CI rate instead of
209
:citric acid, because they don't
want, they want to hide the idea
210
:that there's an acid in something.
211
:, so you, , you kind of just use your
terminology it's there, but yeah,
212
:you've gotta know what you're looking.
213
:JENN: So what can the regular person
do um, is is there a better way to
214
:talk to your, your dental provider
about this, uh, as a patient, um,
215
:like what, what can each
person listening to this take
216
:action on.
217
:ROB: I think there are.
218
:Different levels.
219
:Uh, us as patients and I talk
about me cleaning my teeth.
220
:I can make a move to
using toothpaste tablets.
221
:If I do that, then I will use,
uh, one with fluoride in it.
222
:Um, there are, uh, flosses that, uh, are
made out of corn starch and corn fiber.
223
:So those are biodegradable and,
uh, . , toothbrushes that we can get,
224
:which don't, uh, don't use plastic
or, or at least if you, you can
225
:move in the right direction and not
use as much plastic talking to your
226
:dentist or your orthodontist about it.
227
:And it, again, we go back to the
carbon monk and their children's ARMAC
228
:and how, uh, we want to encourage
children to talk to their parents.
229
:And if, if children are,
um, uh, thinking about this.
230
:You know, they can talk to their
parents and that helps with the family.
231
:And this can all be raised
with the orthodontist as well.
232
:So it is a conversation, isn't it?
233
:The dentists, I think, , have to make
a decision on how they use plastics.
234
:And so for me, it's trying
to use the paper cups.
235
:So.
236
:Um, in some countries, you, you
can autoclave your, uh, glasses
237
:between patients, but that's
discouraged in our countries.
238
:So we use paper cups
rather than plastic ones.
239
:Think about how many patients we see.
240
:Yeah, that's a lot of paper cups.
241
:Uh, there are some plastics that we
have to use to protect ourselves.
242
:, but if we aren't constantly on the
lookout to try and work out ways, um, ways
243
:around things, , selling products like.
244
:These things that patients might want,
, and the industry itself, I think if
245
:the industry can, , start to provide
products so that, , small companies
246
:can, have , larger amounts bought from
these companies and then they can sell
247
:on so that they're using, I think often
it's easier for a company if they have
248
:a big, , purchase from one company
and then that company that's selling,
249
:a lot of other products can then sell
'em onto us, probably makes it easier.
250
:So bigger companies need
to have an awareness.
251
:I think setting
252
:JENN: When I worked in the hospital
system for 23 years, um, when I first
253
:started Everything was reusable.
254
:You know, we had, we didn't have
plastic, kidney basins, they were
255
:stainless steel and we had drap
cloths and we had, uh, cloth gowns
256
:with the tight cuffs and everything
got autoclaved or reused or washed.
257
:And, and we've really gone away from that.
258
:And I really hope we can start going
back to that because those things.
259
:As well,
260
:and it gave people jobs
in the washing and the
261
:sterilizing
262
:department.
263
:Um,
264
:Yeah.
265
:ROB: And our other thing is , the
aligner industry that's taking off.
266
:Um, I talk, I've talked to my colleagues
about this and I think just before
267
:lockdown, actually, I looked at the
figures for, uh, one of the big aligner
268
:companies, uh, who were, I suppose,
in their literature saying, you know,
269
:we've, , treated 8 million patients.
270
:And then I looked.
271
:Uh, and I thought, well,
that's how many aligners?
272
:The average is 25 aligners per hour.
273
:That's 50 aligners.
274
:That's, uh, 8 million a year.
275
:That's one centimeter.
276
:And I worked out how long
the aligners would go.
277
:And I think it was somewhere like from
Birmingham in the UK to north Africa
278
:every year in an these aligners.
279
:And of course they're, they're non
recyclable because use multiple
280
:types of plastic to create them.
281
:And so, , at the moment, the industry
is trying to create aligners that can
282
:be recycled, um, or ways of sending
them back so that they can be treated.
283
:and.
284
:Potentially reuse for other forms,
but at the moment, the align, the
285
:aligner industry is really taking off
because, , patents have, uh, have changed.
286
:And so it's becoming easier for
people to make their own aligners in
287
:house and provide them to patients.
288
:So it's going up rather than down.
289
:And I think there are other ways of
treating patients where you're not having
290
:to use something that's not recyclable.
291
:So, uh, I think align is the
right thing for some people.
292
:So we use them, but, uh, it's just,
I don't wanna just go down the road
293
:of converting my practice to just
using something that's non recyclable.
294
:I feel uncomfortable about that.
295
:JENN: it's good to hear someone in
the industry talking about this.
296
:I have, not, , heard
this so far, so I'm very
297
:happy to hear
298
:ROB: Well, we, we, I mean, in
dentistry, it probably, uh, and as
299
:these figures probably relate to
the UK, it's about 3% of the carbon
300
:footprint of the overall, , medicine.
301
:So I think there's lots that can
be done in, in medicine in general.
302
:Leekei: Oh,
303
:yes.
304
:Hmm.
305
:ROB: it's something to be
worked at that's for sure.
306
:Leekei: Yes, but you need to
choose what, um, What goes first,
307
:you know, safety or environment.
308
:And I think in the medical
field, it's very often is
309
:. Patient's safety first, right?
310
:ROB: well, you are, you
are absolutely right.
311
:And that's, I think one good way
that we could use our governing
312
:bodies in a, proactive way.
313
:So in the UK, for example, we have the
care quality commission and they can come
314
:around your practice and assess you and
they can literally just turn up if they
315
:want and they'll look through and redo.
316
:Critique, and this is put on a
website, so you can be really
317
:criticized for what you're doing.
318
:And there isn't anywhere in
the CQC sees inspections.
319
:That really looks at how green
you are or how green you are as a
320
:practice or how sustainable you are.
321
:And it, I think it would be quite a
nice thing for, the CQC to develop is.
322
:is.
323
:actually a section of the examination
to see where you are on that.
324
:\ what auditing are you doing on
the products that you're using?
325
:The whole host of things that
could be done to improve the
326
:regulation of the industry.
327
:And again, it would all make people
just more aware that, uh, this is
328
:an area that it doesn't need to
be looked at and is an important.
329
:Leekei: I used to wear contact
lenses and their dailies and I've
330
:been using it since I was 17, I think.
331
:And.
332
:It's, this comes in a small thing, plastic
thing, and then you there's a pill.
333
:And I have two eyes.
334
:So obviously I'm using
two every single day.
335
:So that's 60 a months.
336
:And I very quickly realized that it's
was not good for the environment.
337
:And even though, , Now some people
think, and I used to think that plastic
338
:can be recycled a hundred percent,
but even though it could be recycled,
339
:I just, something didn't come up.
340
:Right.
341
:So I decided to switch from my Del
342
:to monthly.
343
:Now.
344
:JENN: Yeah, I have monthly ones too.
345
:And, and I, they last a
whole lot longer than that.
346
:Cuz I wear my glasses a lot
347
:Leekei: Okay.
348
:I do the same thing,
but I didn't dare, just
349
:JENN: but you know,
350
:Leekei: the one.
351
:JENN: no, I, I, I write down
the dates, I wear them and then
352
:I count up a
353
:month and that's good.
354
:So they last
355
:probably about five months, but
356
:What the heck
357
:Leekei: Hmm.
358
:JENN: I was thinking as I was
taking a, one of those rapid COVID
359
:tests the other day, because I was
going into a healthcare facility to
360
:visit, um, a congregation member.
361
:I was looking at the plastic
that was in one of those kits.
362
:And I don't know if the
363
:kits
364
:are all the same,
365
:but you know, they come with all this
stuff, including some little holder thing.
366
:That's hard plastic.
367
:That's got all these little
holes in it and you only need
368
:one
369
:one hole to do this
thing, uh, for this test.
370
:And I don't know if anyone else
experienced the horror . Seeing this
371
:kit that was then just thrown right out.
372
:I mean, I get it.
373
:We have
374
:to do this,
375
:but at the same time, oh my goodness.
376
:I wonder who was inventing this and
377
:whether
378
:they were thinking
379
:about, you know, everyone getting
380
:these
381
:kits and using them multiple
382
:times a
383
:week.
384
:some
385
:people do I've only
ever had one because I,
386
:um, Ha haven't worried about testing
myself in other contexts other than
387
:going into healthcare facilities.
388
:But yeah, it was an interesting experience
and I sat there just looking at all
389
:this stuff, going into the garbage and
thinking, oh wow, there's so much work.
390
:We have to
391
:do
392
:ROB: yeah, yeah.
393
:With it.
394
:It's funny how.
395
:People were trying to, I think there
was just certainly this thought
396
:about plastics before COVID and then
suddenly COVID hit every was just
397
:covering themselves with plastic.
398
:And just though it's thrown
out the window a bit.
399
:Um, yeah.
400
:It's um, it's just, it's
a struggle, isn't it?
401
:Leekei: Yeah, I think COVID made
us live in the ocean of plastic,
402
:you know, just think of all the
masks that we use every day.
403
:And that's, there's a lot of plastic
404
:,
in in the
405
:masks.
406
:ROB: Yeah.
407
:Yeah.
408
:Well, fortunately my wife bought
lots of these LA, um, masks, and so
409
:we had a rack that was put by our
door so that if we forgot, we could
410
:just pick one up as we were going
out and, uh, yeah, quite like that.
411
:we, we still have to give people
plastic masks and people don't
412
:bring their own to the practice.
413
:So we are giving out these masks
and they're more of a problem.
414
:So, and again, it's not that
easy to find these things and,
415
:um, find plastic free ones.
416
:Leekei: but because you care, you're doing
417
:things differently.
418
:ROB: Yeah, I think it's always
about moving the right direction.
419
:Isn't it?
420
:It's, uh, you can't always completely
clear the whole business of it, but if
421
:you're, if you're trying, then it's the
first step, isn't it like cycling to work.
422
:It's like cycling to work.
423
:JENN: I
424
:wish I could
425
:ROB: yeah, so I, I have my bike and I put
it outside the practice and we are just,
426
:we are just having a refurb done at the
moment and I've made sure that we are
427
:having a bike rack put into the car park.
428
:It's only a small car park, but we'll
have more space when we've finished.
429
:And so again, that's another
part of, you know, people can
430
:put their bikes in there and see.
431
:This is another way of transporting
yourself around Birmingham.
432
:Cause we have a lot going on in Birmingham
to try and encourage more cycling.
433
:Uh, I realize that it's not possible
for everybody, but again, it's just
434
:trying to encourage that thought.
435
:Isn't it.
436
:JENN: That's a great idea.
437
:I have a little old electric
car and, um, I can get to work,
438
:but then I have to plug it
439
:into the wall.
440
:and
441
:trickle charge.
442
:Before I'm able to drive home again.
443
:Cause
444
:otherwise I
445
:won't get
446
:home
447
:and range.
448
:Anxiety is real
449
:but, um, yeah, it works.
450
:ROB: yeah.
451
:Well, it's for me, it's a slightly
different range of anxiety because
452
:it's a very steep, uphill home.
453
:it's anxiety of hill.
454
:JENN: Hey, you get your workout at
the same time as getting to work.
455
:That's excellent.
456
:uh, that's good.
457
:Well, it's been great having this
conversation and, uh, thank you so much
458
:for your insight and your information.
459
:Um, I've learned a
460
:few.
461
:things
462
:ROB: Well, good.
463
:I happy was of help.
464
:Leekei: thank
465
:you so much.
466
:ROB: Thank you.
467
