I bit the side of my tongue a few times and a white growth appeared. it seems to be slowly getting bigger and not going away. any ideas?

Trauma: If the tissue has become fibrotic (hard feel), you may need to have it removed so you can function without more trauma to the tissue. It is best to remove it when it is smaller rather increased in size, which it will ultimately do. Contact a oral surgeon to have it evaluated. Chronic trauma can become pre-cancerous.

Ulceration likely...: Ulceration most likely. Sadly once you bite your tongue, you are susceptible to biting it again. See your dentist, as it is always best to check any mouth lesion for a possibility of oral cancer. Most tongue bites heal in about two weeks. Rinsing with warm salt water may be comforting or you can use arnica or aleve, (naproxen) Motrin or advil for swelling and pain.

Need see doc: If it is not going away, you need to have it looked at. If it was not there until you bit it, likely is ok. But would tell you to have it checked.

How long?: The growth could just be from the trauma of the bite or not, so i recommend that you see your dentist to have it evaluated and possibly biopsied to rule out a cancerous lesion.

GET IT CHECKED: Constant irritants to the tongue, by biting, can cause it to swell and actually make it even easier to keep biting your tongue. The sore can become more and more irritated and become infected and get much worse. Get to a dentist and/or oral surgeon.
