I recently started using Crest Pro Health Intense Cleaning toothpaste, now it feels like it has burned the inside of my mouth.  Whenever I try to eat anything my mouth burns and swells.  Also, I noticed that my skin around my eyes I very dry, itchy and peeling.  Could this be and allergic reaction to the toothpaste and what can can I use to clear it up?
The problem that you have seems like an allergic reaction, but it can be confirmed only after evaluation by a dentist. Please avoid using the toothpaste and visit your dentist as soon as possible.
