Because you’re right here, you’ve got doubtless heard that glycerin is a horrible, horrible, no good, very unhealthy ingredient to have in toothpaste.
Many pure sources say that regardless that you are already doubtless avoiding fluoride and that terrible SLS (Sodium Lauryl Sulfate–a foaming agent) in toothpaste, you’d higher be avoiding glycerin too.
Ack! As if we do not have sufficient to be involved about–now we have to fear about glycerin too?!
This certain is a tough tablet (or blob of toothpaste) to swallow as a result of glycerin is in most toothpastes–both typical and pure. (Oh and if you happen to’re utilizing toothpaste with fluoride in it, don’t swallow any toothpaste and DO name Poison Management if you happen to do–but I digress).
Welp, by no means concern. I’ll break this down for you and current you with a fairly stable debunking of this complete glycerin toothpaste fantasy.
Figuring Out What’s Wholesome Is Laborious
After awhile, all of this wholesome dwelling data will get actually laborious to wade by way of, would not it?
First, you hear that eggs are unhealthy for you, then they’re good.

To begin with, if you are going to seize one thing, could I encourage you to as a substitute select this Wholesome Chocolate Ice Cream and these Sugar-free Snickers.
Second, you will quickly see that you just in all probability need not toss your toothpaste.
What’s Glycerin?
Often known as glycerol, glycerin is a pure compound derived from vegetable oils, animal fat, or petroleum by way of fermentation of yeasts, sugars, or starches. It is clear, colorless, and odorless, and could be very very candy.
A Swedish chemist, Karl Wilhelm Scheele, unintentionally found glycerin in 1779 when heating a combination of lead oxide and olive oil.
It may be used as a candida-safe sweetener, like in these Do-it-yourself Sugar-free Marshmallows, however can be utilized in private care merchandise, like this Do-it-yourself Foaming Cleaning soap. It is usually utilized in glycerites (that are one other kind of sweetener) and because the base for alcohol-free “extracts” like this Alcohol-free Vanilla.
What Is Glycerin Made From?
The commonest sources of glycerin are natural–coconut, soy, and palm.
Within the 18th and 19th centuries, folks typically used candles and soaps containing animal fats to make glycerin.
Nowadays, plant based mostly oils are extra generally used for making glycerine.
Petroleum may also be used to make glycerin however that technique of constructing glycerin wasn’t found till 1948. It is extra pricey to make glycerin this manner so it is not the supply of most glycerin in the marketplace.
When you’re involved about GMOs, merely select natural or non-GMO glycerin to keep away from such issues.
Once I Nearly Tossed My Toothpaste aka Destructive Claims About Glycerin
I consider it was within the guide Treatment Tooth Decay the place I first learn that glycerin is unhealthy on your tooth. The writer said that glycerin coats tooth enamel and that it might probably take quite a bit of brushing to get that coating off.
Oh the panic I felt once I ran to the toilet, pulled out our pure toothpaste, and browse the phrase “GLYCERIN” proper there, in black and white on the label.
Right here I used to be making an attempt to be oh so wholesome by selecting a pure toothpaste, and now this?!
As time went on, I heard an increasing number of folks speaking about this.
I discovered some toothpastes with out glycerin, however then later actually wanted remineralizing toothpastes, and guess what–they just about ALL had glycerin in them, so I hesitatingly purchased some and used then, pondering “Properly, it might probably’t be all that unhealthy. Can it?”
Then lately, I began questioning once more and began researching….and located some troubling data within the type of a type of scary (to me) examine.
That led to extra research–which led to this publish.
Did I Discover the Research Proving Glycerin Is Dangerous for Your Enamel?
Most authors who declare that glycerin would not forestall remineralization state that they cannot discover a single examine exhibiting that glycerin is an issue.
That appeared to be the case, however sooner or later, whereas studying by way of the feedback of a publish, I discovered it. Somebody shared this examine, saying that it confirmed that glycerin reduces the hardness of tooth.”
And sure, it appeared to just do that.
The Research Particulars
Within the examine, quite a lot of substances (together with plain glycerin) have been utilized to ready (useless) tooth fragments, and left there for 8 hours. Then the fragments have been submerged in synthetic saliva for 16 hours.
Here’s what the researchers concluded:
Glycerin additionally offered slight decreases in microhard-
ness for sound enamel and dentin, just like the impact
of carbamide peroxide. It may act as an adsorbed layer
barrier to synthetic saliva and to a remineralizing impact.https://www.researchgate.web/publication/7500507_The_effect_of_10_carbamide_peroxide_carbopol_andor_glycerin_on_enamel_and_dentin_microhardness
At first look, this appears to be the loss of life knell for glycerin-containing toothpaste.
Not. So. Quick.
Issues With the Research
Glycerin’s Outcomes
To begin with, the management was a ten% carbamide peroxide answer. Of their phrases “it [carbamide peroxide] is accepted as secure and efficient by the American Dental Affiliation (ADA)”
What meaning is that the management substance had already been decided to not injury tooth, and glycerin carried out higher than the management in most facets of the examine.
The Synthetic Saliva Issue
Notice that all the substances they examined confirmed decreased microhardness, however we don’t a lot about their synthetic saliva besides different research they referenced the place they used it. How do we all know their saliva wasn’t already reducing the micro hardness of the tooth?
It will have been significantly better to have water or one other substance (xylitol, erythritol, or sorbitol would have been good choices) as one other management. Or their synthetic saliva alone would have been good to have as a management to know what that did to the tooth.
Additionally notice that the answer was “supersaturated” with minerals. That signifies that the water had so many ions in it that nothing else may dissolve in it. Take into consideration what occurs if you happen to dump a number of salt right into a small glass of water. Sooner or later, you simply cannot dissolve any extra salt into the water.
So, the unreal saliva was so saturated that the glycerin wasn’t in a position to dissolve and the minerals within the synthetic saliva answer attain the tooth for remineralization. Nothing else may dissolve within the saliva solution–that actually complicates issues.
That is Not How Toothpaste Works
Whereas this examine is fascinating, it is not how toothpaste works within the mouth.
Enamel do not sit in an answer of toothpaste and saliva. Your mouth regularly produces saliva (ever discover how your mouth fills up whenever you’re brushing?) Additionally, you rinse your mouth after you are finished brushing, and once more, the saliva in your mouth is not supersaturated.
Who Began This Glycerin Fantasy Anyhow?
It appears the entire demonizing of glycerin factor began with Dr. Gerald Judd (Chemistry Ph.D.) who wrote quite a bit about dental well being a lot of years in the past.
Judd appeared to be making an attempt to determine methods to maintain tooth wholesome and had some fascinating views.
initially claimed that glycerin leaves a coating on the tooth that in keeping with him “takes 27 washes to get it off”.
He additionally mentioned that “tooth brushed with any toothpaste are coated with a movie and can’t correctly remineralize”.
Curiously, he really helpful brushing tooth with cleaning soap, (notice that he said that it solely takes 2 rinses to take away cleaning soap out of your tooth)–perhaps that is the primary crimson flag since would not that imply that his really helpful cleaning soap is sticking to tooth too?
Others declare that not solely does glycerin inhibit tooth remineralization, however that it is a plaque magnet resulting in the expansion of unhealthy micro organism, which might trigger unhealthy breath, gum illness, and even tooth decay. Yikes!
So I went on a hunt for an additional toothpaste and went on my manner utilizing one other model for awhile.
However the entire matter nonetheless bugged me sometimes, and sooner or later I made a decision to analysis it additional.
This is what I discovered…..
However is it unhealthy on your tooth? Let’s discover out!
Different Dental Claims By the Similar Physician That Do not Make Sense
To begin with, Dr. Judd did not write largely about glycerin.
In actual fact, he did not write a lot about glycerin in any respect.
Most of what he wrote was about different tooth-related points.
For some cause, nevertheless, this glycerin factor has gotten essentially the most traction within the pure well being enviornment,
A few of his different ideas, well–
Simply because somebody makes incorrect (and even wacky) statements about different issues would not make their different claims improper, however it may be a trigger for concern. Both the individual would not know what he/she is speaking about, would not analysis properly, is a sensationalist, is loopy, or is mendacity.
Dr. Judd, whereas he does have a a lot stronger background in chemistry than I do with my faculty degree chemistry course, mentioned some issues about tooth that do not make sense. You’ll find a brief define of a few of his claims right here, a letter to his followers right here, and a full copy of his guide, Good Enamel from Beginning to Demise right here.
Whereas Dr. Judd appeared to imply properly, following are just a few issues in his reasoning.
Brushing With Cleaning soap
Dr. Judd claimed that as a substitute of toothpaste, brushing with cleaning soap is the best way to go, stating that you solely want 2 rinses to get cleaning soap off of your tooth.
Would not that imply that cleaning soap sticks to your tooth too? And in that case, what number of rinses is OK for one thing that you will use in your tooth? 2 is OK however 27 is not? Is 5 OK?
Maybe brushing with cleaning soap works, however there’s really glycerin in most bars of cleaning soap, so that is all very complicated certainly.
Sugar Would not Trigger Cavities
Dr. Judd additionally claimed that sugar would not trigger cavities.
Actually.
Judd based mostly this declare on what he noticed after after including sugar to bone materials The bone materials wasn’t affected negatively by the sugar.
In fact that is not how cavities work. Sugar feeds the micro organism on the tooth which then deposit plaque on the tooth and then–you get cavities!
Micro organism Would not Trigger Cavities
Judd mentioned that since skeleton tooth buried within the floor did not have cavities, regardless of being in touch with micro organism within the grime, that micro organism would not trigger cavities.
In fact there is no such thing as a saliva within the grime and the identical carbohydrates and similar strains of micro organism which can be within the mouth are lacking too.
This is not to say that Dr. Judd was silly and that the whole lot he mentioned was improper. Nonetheless, it appears that evidently his total views on dental well being have been overly simplistic and did not have in mind quite a few essential components.
Proof That Glycerin Is Truly GOOD for Your Enamel
So now that the type of scary examine about glycerin is debunked, and Judd’s reasoning is debunked, let’s speak about glycerin’s positives.
In fact we’re speaking about different points right here greater than what the FDA thinks about glycerin, however for the document, the US Meals and Drug Administration acknowledges glycerin as being secure.
There are additionally many research exhibiting that glycerin has helpful properties.
Whereas they are not all straight relevant to dental well being, you’ll be able to simply see the connections.
Decreased Streptococcus Mutans (supply)
Reduces Biofilm (supply)
Promotes Therapeutic (supply)
Bacteriostatic (supply)
Is Sorbitol Higher for Toothpaste Than Glycerin?
Some pure toothpastes use sorbitol as a substitute of glycerin since sorbitol additionally acts as a sweetener and helps preserve toothpaste from drying out (but it surely would not have glycerin’s preservative properties.
It is essential to notice that regardless that sorbitol is not practically as cariogenic (causes cavities) like glucose, it nonetheless can result in cavities. So although it would not look like a very huge deal, technically it is not one of the best factor to have in toothpaste (supply).
Advantages of Glycerin in Toothpaste
As an alternative of being a foul man, here is why you have to be glad glycerin is in your toothpaste.
Makes It Style Higher
Glycerin is nice. So your toothpaste tastes higher with it in there and also you and your kiddos are due to this fact extra prone to brush with it.
Prevents Toothpaste From Hardening (Turning into Cement)
Properly, not likely cement, however if you happen to’ve ever left the cap off of your toothpaste, you understand what I imply.
Glycerin is a humectant (it attracts water to itself) so it helps preserve toothpaste from drying out within the tube. Glycerin additionally has this perform in my Moisturizing Do-it-yourself Foaming Hand Cleaning soap and it may be discovered in lots of skincare merchandise and cleaners as properly, to maintain them (and also you) from drying out.
It is Bacteriostatic (Kills Dangerous Bugs)
In gentle of the issues about glycerin being unsafe on your tooth, that is actually fascinating to notice. Not solely does glycerin not persist with your tooth to forestall remineralization, but it surely so occurs that it is bacteriostatic and antimicrobial.
Meaning it really does much more than simply preserve your toothpaste from drying out–it is really good on your tooth and might forestall cavities, periodontal points, and even might help your tooth be whiter. (supply)
Reduces the Want for a Preservative
When a formulation is 50% or extra of glycerin, you should not want a preservative, which is nice. I like avoiding the usage of preservatives in my private care merchandise at any time when I can.
Water and aloe in private care merchandise, however, are micro organism and mildew breeding grounds, so glycerin is a significantly better base for toothpaste.
Pure Remineralizing Tooth Merchandise I Love
Whereas there are many pure toothpastes and dental well being merchandise on the market which have some nice evaluations, I’ve just a few favorites.
Theodent has theobromine in it, which appears to have legitimate analysis behind it exhibiting that it’s simply nearly as good as, if not higher than, fluoride at conserving tooth wholesome.
Nice tasting flavors too, together with Chocolate Chip for the kiddos :).
I purchased a number of of those toothpastes once I was ending up this publish and I LOVE them. So zingy and my mouth feels AMAZINGLY clear.
I really like the alkalinizing philosophy–makes a number of sense!
Code WHOLENEWMOM will get a pleasant low cost too!
I additionally LOVE this mouthwash from this firm. It took away sensitivity on a tooth after only one use, and at my final hygiene appointment, my (very choosy) hygienist mentioned that my tooth had little or no plaque on them and requested if I might modified something.
The one factor I might modified was that I began utilizing the mouthwash from right here. Their different merchandise look fairly nice too, however I. Love. This. Mouthwash.
Sure, it is not low cost however actually you solely want a teensy quantity to get outcomes. I attempt to stretch out my merchandise at any time when I can and also you undoubtedly can with this one. Simply preserve it in your mouth so long as you’ll be able to.
Disclaimer: we might simply moved my hygiene appointments from 6 months to 4, in order that is likely to be a part of it. Nonetheless, once I began coming to their workplace I used to be on a 3 month schedule. So I feel it is extra doubtless that this product is doing wonderful issues. Time will inform…..
Notice that all of those merchandise have glycerin. If glycerine was a severely scary tooth enemy, there is not any manner my dental well being would have improved this rapidly. Plus the great evaluations on the merchandise would doubtless not be there. I do know–reviews aren’t at all times reliable, however I am tremendous choosy and I am telling you my trustworthy expertise.
Glycerin can be in most remineralizing toothpastes in the marketplace. I am unable to confirm each constructive evaluations from these, however I feel the science (and my outcomes) converse for themselves.
Conclusion
So there you have got it. Glycerin shouldn’t be scary for the Tooth Fairy or for us, and in reality it might probably even be your tooth’s good friend. Perhaps not their BFF, however a minimum of they’ll and may hang around collectively.
In abstract, glycerin is secure and non-toxic and sure helpful for oral well being. The parable that glycerin is dangerous on your tooth is simply that–an unverifiable fantasy.

I had hunches about fairly just a few of the factors concerning that, however her help was very useful. She’s a sensible woman – and appears to have some nice toothpaste too.
