Other Causes of a Black Spot Inside the Cheek
When you see a black spot inside your cheek, you may immediately be concerned that it is cancerous. Rest assured that this is not likely the case, and that treatment may not be necessary.
The Oral Cancer Foundation lists several causes of dark spots inside cheeks that aren't related to cancer. For example, the inner lining of your cheek may just be patchily pigmented. You could have a benign melanotic macule, which is a spot similar to a freckle that can appear in the oral cavity. Alternatively, if you have put pencils in your mouth in the past, the graphite may have become embedded in your mouth lining, creating a dark spot.
Very rarely, a black or dark spot on the inside of the cheek could be a sign of oral malignant melanoma or another type of oral cancer. For this reason, it's always worth seeing your dentist if you notice an abnormal spot in your mouth that doesn't go away, bleeds or grows larger. Your dentist can diagnose the cause of the black spot through an examination, and they may take a sample to send for analysis.
Maintaining a good oral health routine can reduce your fears about a black spot inside your cheek. As well as brushing your teeth twice a day and flossing once a day, regularly check inside your mouth to make sure your gums and the lining of your cheeks look healthy. Report any concerns or symptoms to your dentist, and you can work together to find a solution.
