My dad is a dentist and told me ages ago about the correlation between sodium lauryl sulfate, a common detergent in virtually every toothpaste (it's the stuff that makes it foam up), and canker sores. The trick was finding a toothpaste that was free of this suspect ingredient. When this Rembrandt version came on the market, I immediately gave it a try. I haven't looked back.

I used to experience outbreaks about every eight weeks. Now I get canker sores perhaps twice a year, and they last half the time they used to. Yes, the dentist-applied treatments such as Debacterol work well, if painfully. However, it's much more satisfying to avoid the problem in the first place.

Does it whiten your teeth too? Beats me. I haven't noticed. All I know is that I rarely get canker sores anymore. Whiter teeth are a bonus.

Did nothing to prevent or cure; more comfortable to brush with though  Sep 21, 2010
By J. Leonard
Quite a tide of positive comments on this. Unfortunatley, I cannot join it so enthusiastically. I paid $8 for a tube of the Rembrandt Canker Sore toothpaste, which provides enough to last three weeks at most with twice a day brushing. I have suffered from canker sores throughout my life, and have never found any particular trigger or useful cure other than patience and pain-numbing Kanka medication. I not only suffered through the normal healing time of canker sores while using the Rembrandt Canker Sore toothpaste, but actually ended up getting more canker sores. While I doubt the toothpaste caused those additional sores, it certainly didn't prevent them. The one plus was that while having a canker sore, this toothpaste was nearly painless to brush with unlike many others. Rembrandt Canker Sore toothpaste seems to be nothing but a sodium lauryl sulfate (SLS)-free toothpaste and nothing more--i.e., no miracle cure in the ingredients. Other companies also make SLS-free toothpastes, but should probably wise up to the marketing smarts of Rembrandt and stamp "Canker Sore" on their tubes.

Good luck to all you fellow canker sore sufferers. I feel your pain, including right now!

Canker Sore Relief has finally arrived.. This stuff really works!!  Feb 10, 2007
By Ramsis Lion "ramsislion"
For an unknown reason I have been getting canker sores on my tongue over the past 2 years. They would come and go. After suffering through painful episodes of not being able to eat, talk or move my mouth for 3 days worth of time it would go away only for another to appear in a different location. It became an endless cycle of suffering that was stressing me out and making my life a pure discomfort to say the least.

I tried every over the counter medication out there that you can get from every drug store in the area. Some did take the pain away but none of them truly eliminated the problem.

That was until I tried this toothpaste. This stuff works. It really works. It wasn't until I started to use this stuff regularly that the problem truly went away. I was skeptical at first, there were so many other products out there that said the same thing "Help eliminate canker sores" but this truly did what it said it would.

Just brush your teeth daily in the morning with the regular amount of toothpaste you normally use. Make sure you take your time to brush with this paste and in a very short time period you will notice that the outbreak of canker sores has come to an end.

I can't recomend this stuff enough. It really has been a life changer for me and delievers as promised. Once you start using it, you won't go back to any other alternatives. The mint flavor is mild and the toothpaste itself helps clean and whiten your teeth. So you are getting two services for the price of one with this product.

Finally canker sore victims can give a sigh of pure pain free relief. Thanks to Rembrandt, Extra Whitening and Canker Sore relief toothpaste. If you are looking for that relief to your canker sore outbreaks. This is the product to get. It works! It works! It works!

Great Product!!  Feb 01, 2007
By Angelica "AngieInOhio"
Works great but I wish I could find it in stores. The one RiteAid that does carry it, doesn't always have it in stock. I also can not always find it in just any Rite Aid. Some don't carry it at all...annoying!

My daughter is the canker sore sufferer. I did some research before I discovered Rembrandt, and found that the ingredient, Sodium Lauryl Sulfate, found in almost all toothepastes is the culprate. Rembrandt for Canker Sores does not contain this key ingredient. Sodium lauryl sulfate (SLS) is what makes our toothepaste foam. My daughter hardly ever has anymore canker sore breakouts. If she does, it seems to be from getting a cold. Try and find a toothpaste without SLS...they aren't out there. It would be nice to have some competition to bring the price down and be more readily available. But all in all, I'm glad someone has made this product available, even if it's pricey and hard to find.

Worth every penny!  Jan 25, 2007
By Dawn
I first tried this toothpaste a couple years ago, but because it was so expensive, only used it when I started to feel a canker sore coming on. To my amazement, the cankers never did erupt, and were often gone by the next day! I continued to use it in this manner for several months. The one time I forgot to re-order it, I ended up with a mouthful of canker sores. Now I buy it in the convenient 3-pack because I never want to run out again! I also have been using it regularly, and so far have not had any canker sores at all.

This is the most amazing product. I've suffered from canker sores my whole life, always getting 2 or more at a time, and they would take forever to heal. Often it was too painful to even talk, much less eat. I tried every product on the market over the years, and only a couple of them even offered temporary relief. I am absolutely ecstatic to have discovered this toothpaste, and will never be without it again!

Yes, it's expensive, but if you're a true canker sore sufferer, it is worth it's weight in gold!!
