A Canker Sore Cure How To Treat Canker Sores | Sls Free Toothpaste

SLS-Free Toothpastes

Canker Sore Toothpaste Reviews

Below is a list of non-canker sore inducing toothpastes, along with their ingredients lists. None are made with sodium lauryl sulfate (SLS).

You’ll find that an SLS free toothpaste is usually a little more expensive than the toothpastes you can buy in your local supermarket but, for many people, freedom from canker sores is worth the extra price.

Squigle Enamel Saver Toothpaste


This is really the king of canker sore toothpastes because it was created specifically for people with mouth problems such as canker sores. Amazingly, it also helps treat a bunch of other mouth problems, such as bad breath, gum disease, bleeding gums, gingivitis, mouth ulcers from cancer treatments, perioral dermatitis, plaque, tartar, cavities and surface stains.

It does all that but it doesn’t have any harsh abrasives, irritating tartar control agents or bleaches. Plus, it’s free of SLS and other mouth-irritating ingredients. But it’s not available in grocery stores or even health food stores.

Aside from not having canker sores any more, you may not be able to tell the difference between Squigle and your old toothpaste. It has the same smooth texture and a pleasant mild mint flavor – although not as overpowering as with some toothpastes.

Recommended by dentists and hygienists for canker sore prevention.

Tom’s of Maine®


After dismissing the idea of sodium lauryl sulfate as a cause of canker sores, Tom’s of Maine® has jumped on the bandwagon (sort of) with some excellent new SLS free toothpastes. Coming in both spearmint and peppermint flavors that taste great and have a familiar toothpaste texture.
They don’t specifically address canker sores on the label, choosing to target gentle cleaning instead, but a toothpaste without SLS is good no matter what the intended purpose.  Plus, they have some other ingredients that are excellent.

This toothpaste, officially called Tom’s of Maine Clean & Gentle, is a good choice. It has a great texture like most commercial toothpastes, plus it has several great flavors that are pleasant without being overpowering.

You’ll notice that this toothpaste also has xylitol and licorice root (glycyrrhizin).

Xylitol is a natural sweetener that is vastly superior to the sweetener found in most toothpastes: saccharin.

Xylitol is extracted from the fibers of birch, raspberries, plums, corn and other fruits and vegetables. But unlike any other sweetener, xylitol not only helps prevent cavities, it is believed to help your mouth remineralize damaged teeth.

Saccharin is chemically derived (from coal tar!) and has been linked to cancer and migraines. In my opinion, it’s not fit for human consumption – even if that consumption is just swishing around in the mouth and minimal swallowing.

Licorice root has been shown to help heal canker sores, so it’s a perfect addition to this toothpaste.


  • Glycerin – moistener
  • Water – consistency
  • Calcium carbonate – mild abrasive
  • Hydrated silica – stain removal
  • Organic aloe vera leaf juice – soothing feel
  • Xylitol – sweetener, cavity prevention
  • Carageenan – thickener
  • Acacia gum – flavor carrier
  • Glycyrrhizin – foamer
  • Fruit extracts and natural flavors


The Natural Dentist® Toothpaste


This is another great toothpaste with a familiar toothpaste
 texture. As with Tom’s, The Natural Dentist Healthy Teeth & Gums Original Toothpaste is sweetened with xylitol (and sorbitol) and has a pleasant mild flavor. This is also an SLS free toothpaste, plus it contains no alcohol, no artificial dyes, sweeteners or preservatives. They also offer a flouride-free version for those who don’t want it. There is one small caveat: apparently in some people, the ingredient Cocamidopropyl Betaine can trigger canker sores.*

It comes in a variety of flavors, including peppermint and orange.


  • Sodium Fluoride
  • Vegetable Glycerin
  • Silica
  • Sorbitol – a sweetener found in various berries
  • Spring Water
  • Xylitol
  • Aloe Vera Gel
  • Cocamidopropyl Betaine*
  • Natural Flavors
  • Titanium Dioxide
  • Sodium Caboxymethyl Cellulose – thickening agent
  • Xanthan Gum
  • Grapefruit Seed Extract


Rembrandt® Classic Toothpaste to Prevent Canker Sore


I have not used this toothpaste, mainly because it contains saccharin, which is, in my view, a toxic chemical. It
may prevent canker sores, which is good, but at what cost? Most people can tolerate saccharin without ill effects (as far as they know), but others can’t, so I don’t see the advantage of using it when there are superior alternatives available. I give it a thumbs down for that reason. It also contains Cocamidopropyl Betaine, which is implicated in canker sore formation in a small percentage of people.*

Xyliwhite Toothpaste™


Although it’s not advertised as an anti-canker sore toothpaste, you’ll notice in the ingredients list below that it is SLS free.

It has a good taste and texture and you won’t notice the difference between Xyliwhite and any commercial toothpaste.

The only thing missing in this SLS free toothpaste is fluoride, and if that’s important to you, you could always use a flouride rinse, such as ACT (ACT does use saccharin though), or use Squigle, Tom’s or Natural Dentist instead.

As the name implies, Xyliwhite also uses the sweetener xylitol as a primary ingredient.

Negatives: Tea tree oil (melaleuca) has garnered some negative attention recently because of a report of young boys who ingested it over time and had their breasts enlarge.  This is likely due to a naturally occuring estrogen within the oil.

As with some of the other toothpastes, it contains Cocamidopropyl Betaine, which seems to cause canker sores in a small percentage of people.*
