Can Crest Sensitivity toothpaste cause the same problem as sensodyne?

Answer 1

Crest tooth paste does in fact have information stating that the product has not been completely tested which in some cases is causing negative effects on clients using this product. From my personal experience and knowledge in the dental profession i recommend you use sensodyne, it works great and is CDA (Canadian Dental Association) or ADA (American Dental Association) approved (meaning it the product has gone through scientific testing to make sure the product works to great benefit and is safe to use.

Hope this answers your question :)

Answer 2

Yes, it is possible to be allergic to any kind of toothpaste. The allergy can have symptoms of cheilitis (severely chapped lips), contact dermatitis (irritation and rash), swelling of the gums and tongue, dry mouth among others. If you experience an allergic reaction, such as swelling, redness, dryness, or infection in your mouth, see your dentist immediately to rule out gum disease and to discuss your choice of toothpaste.
