Mouth Growths
Key Points
Most mouth growths are noncancerous. Warts, yeast infections, and repeated trauma (such as biting or rubbing against a sharp tooth edge) are common causes of noncancerous growths. Use of alcohol and tobacco and oral human papillomavirus (HPV) infection are risk factors for oral cancer. Because cancerous growths are difficult to recognize by their appearance, doctors frequently recommend a biopsy.
