Q. The inside of my mouth became very sensitive to salt, acid and anything spicy. When my wife looked, she said it looked like thrush.
I went to my dentist to have it checked out. After a visual assessment and asking about medications, one of his first questions was, "Are you using a cinnamon toothpaste?"
Stopping the cinnamon toothpaste and using a prescription medicated mouthwash called 'Magic Mouthwash' cured the condition in about 10 days. I hope this will help other readers.
A. You are not the only person to experience problems with cinnamon toothpaste. Some people are sensitive to this ingredient and may develop irritation or chapped lips as a reaction to it (Journal of the American Dental Association, Sept., 1995). Pharmacists compound Magic Mouthwash to ease oral irritation.








Cinnamon is not the only ingredient in toothpaste that causes problems. I long for the old toothpaste. I now switch between several brands because any one will cause the lining of my mouth to peel. Fortunately not painful, just disgusting. Original Crest didn't use to cause this, but I can no longer find it.
I started getting a sore tongue from mixing cinnamon into my morning coffee and from chewing all-natural cinnamon flavored xylitol gum. The problem went away as soon as I eliminated cinnamon from my diet.
The last time I tried the gum (just to be sure that was what had caused my discomfort) I woke up in the middle of the night with my tongue lumpy and swollen.
Thank you for this information, I have been having these same problems with my mouth and I did recently switch to Colgate Cinnamon Toothpaste.
Thank you for posting this information. Several years ago I had problems with a sore swollen mouth with the cinnamon toothpaste and now have the same problem with other toothpastes, except Sensodyne.
Even that one causes some burning. If I stop using any toothpaste at all and use only baking soda, the sore, swollen tissues completely disappear.
What are the companies putting in toothpaste these days that is causing so many people problems?
I also would like to find the original Crest toothpaste.
Cinnamon can be tough stuff! when I stopped smoking, almost 30 years ago, my addiction hammered me into devouring some kind of mint or gum as a substitute. At one point I used cinnamon tic-tacs instead of lighting up (I loved the taste and the little "burn" the tic-tacs provided, almost as good as a cigarette).
After many months of this substitute addiction, I found that the inside of my mouth constantly burned and my tongue resembled a map of the world. I stopped the tic-tacs--cold turkey--and within a couple of weeks my tortured mouth returned to normal. I'm currently hooked on altoids peppermint smalls.
Is there anyone who can advise me on how long it'll be before I have to switch to grape popsicles?
I too was using Cinnamon tooth paste when I lost my ability to taste. I can't be sure the Cinnamon only in the tooth paste or the tooth paste alone. But I stopped using it and my ability to taste returned. There are other ingredients in the tooth paste that might have cause it, but Cinnamon is one of the main ingredients.
Aquafresh - fluoride toothpaste (cavity protection ) burns my lips. Cinnamon is not listed as an ingredient.
My mouth peels horribly from almost all types of toothpaste. I have been using Colgate Luminous and I have not had that problem since changing to it.
