A 21-year-old female asked:

White/grey thin oval painful spot under tongue, gone in a week, surrounded by red area, faded away, didn't bust/pop, think was canker sore, safe to kiss?

Trauma?: It could just be an injury or burn (these are often caused by Aspirin left in contact with oral mucosa for too long). If this has been a single isolated incident, that is most likely. Oral herpes viral lesions which are contagious through kissing, usually take 2 weeks to heal and are often on the lips but can be on the tongue as well. Safest bet is to defer until fully healed...

If it is gone: ok to kiss. May be a canker sore, burn, trauma , herpes,.... if it reocurrs have it checked out.

It is safe: If no lesion is present, it is safe to kiss.

I agree. Sounds like an aphthous ulcer. Not contagious although it can be very painful. Warm salt water rinses can be soothing. Avoid spicy and acidic foods which tend to irritate it.

It is most likely a canker sore (aphthous ulcer). Kenalog with Orabase is very effective for these types of lesions if you can get your doctor to write you an Rx. If not, you can use Orajel OE Orabase B over the counter to sooth the pain and discomfort
