Could anyone tell me what this is?

I check my teeth and mouth regularly and this red bump (in the photo) has come up over night.

I'm guessing I probably bit my cheek while asleep? But just wanted to check if it was anything else?

Thanks.

The image is not clear, but I believe it to be petechiae or broken capillaries. When I first look at lesions, I look for regular vs irregular patterns and presentation. Your lesion is regular looking and likely not serious. Irregular lesions are like squamous cell carcinoma which is ugly, usually different colors, irregular borders and patterns. Make sure any lesions resolve after 2 weeks. If any lesions look suspicious (not yours), the only way to diagnose it is with a biopsy.

Thanks very much honestdoc! It's already reduced a bit and starting to look better.

I had just never had anything like that before so wasn't sure what it was.

Thanks for your advice.
