Canker Sore Toothpaste
Recommendations
Below is a list of non-canker sore inducing toothpastes, along with their ingredients lists. None are made with sodium lauryl sulphate (SLS).
You'll find that they are usually 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.
Tom's of Maine
Review:
After dismissing the idea of SLS as a cause of canker sores, Tom's of Maine has jumped on the bandwagon (sort of) with some excellent new non-SLS toothpastes. With a variety of flavors that not only taste great and have a familiar toothpaste texture, the ingredients are really good too. They don't specifically address canker sores on the label, choosing to target dry mouth problems 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 Care SLS-free Anticavity + Mouth Soother,Tooth Paste, 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 sweetener, which is vastly superior to the sweetener found in most toothpastes: saccharin.
Xylitol is a natural sweetener 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.
Licorice root has been shown to help heal canker sores, so it's a perfect addition to this toothpaste.
Tom's also makes this toothpaste without flouride for those who would rather avoid it.
It comes in Apricot, Fennel, Lemon-lime, Spearmint, Peppermint, and Cinnamon/Clove flavors.
Ingredients:
- Glycerin - moistener
- Water - consistency
- Calcium carbonate - mild abrasive
- Hydrated silica - stain removal
- Organic aloe vera leaf juice - soothing feel
- Xylitol - soothes a dry mouth
- Carageenan - thickener
- Acacia gum - flavor carrier
- Glycyrrhizin - foamer
- Fruit extracts and natural flavors
The Natural Dentist Toothpaste
Review:
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. Contains no SLS or alcohol, and no artificial dyes, sweeteners or preservatives. They also offer a flouride-free version for those who don't want it.
It comes in Peppermint Twist and Orange Zest flavors.
Ingredients:
- 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
Squigle Enamel Saver Toothpaste
Review:
Created specifically for people with mouth problems such as canker sores and dry mouth, Squigle is an excellent replacement for regular commercial toothpastes. 
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.
Ingredients:
- Sodium Fluoride 0.24%
- Xylitol 36%
- Water
- Silica
- Glycerin
- Poloxamer
- Cellulose Gum
- Flavor
- Anatase
- Methocel ®
- Glycyrrhizin
- Sodium Hydroxide
Xyliwhite Toothpaste™
Review:
Although it's not advertised as an anti-canker sore toothpaste, you'll notice in the ingredients list below that there's no SLS.
It has a good taste and texture and you won't notice the difference between Xyliwhite and any commercial toothpaste.
The only thing missing is fluoride, and if that's important to you, you could always use a flouride rinse, such as ACT (it does use saccharin though), or use Tom's or Natural Dentist instead.
As the name implies, Xyliwhite also uses the sweetener xylitol as a primary ingredient.
Negative: 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.
Ingredients:
- Xylitol (25%)
- Papain (whitening)
- Water
- Hydrated Silica
- Sorbitol
- Glycerin
- Sodium Bicarbonate
- Cocamidopropyl Betaine
- Natural Flavors - whatever that means
- Carrageenan Gum
- Potassium Sorbate
- Tea Tree Oil
Rembrandt Classic Toothpaste to Prevent Canker Sore
Review:
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.
Ingredients:
- Fluoride Ion
- Dicalcium Phosphate
- Glycerin
- Water
- Xylitol
- Silica
- Alumina
- Sodium Citrate
- Natural Flavors
- Cocamidopropyl Betaine
- Sodium Carrageenan
- Papain
- Citric Acid
- Sodium Saccharin
