I have a strange sore in my mouth, near where my wisdom tooth came in. it is white and firm, but painless. likelyhood this is cancer?

Need more info: It is not feasible to provide a meaningful opinion without examining the lesion. It would be prudent to see your dentist.

Compressed tissue: Probably the eruption of the wisdom tooth is causing the tissue to compress. There also could be food caught between the tooth coming in and the tissue around it. Normally gum tissue is soft, so have your dentist check it.

Get it looked at: It is always wise to have a lesion like this checked out by an Oral Surgeon. He or she will take a biopsy and you will know for sure. Best of luck

Strange sore: Any sore or lesion that lasts longer than 10-14 days should be examined. Call your dentist or an oral surgeon for an examination.

See DDS ASAP: Any white lesion that does not resolve itself in two-three weeks should be evaluated and considered for biopsy to obtain a definitive diagnosis. Regardless, pain or painless.

White lesion: Statistically the chances of it being cancer are small, but all white lesions require evaluation, and that's not an internet function. Don't take any advice that tells you otherwise. Please make an appointment to see your Dentist. Wouldn't it be nice to be examined and then told that everything's OK?

White lesions: There are many causes for what you describe and although most are neither serious nor cancerous, it absolutely needs to be first clinically evaluated by a dentist and biopsied for a definitive diagnosis if warranted. Every so often I biopsy a white lesion that comes back with a precancerous diagnosis. Better to be safe than sorry. See an Oral Surgeon.
