ello Dr.,

Just noticed a tiny blood blister underneath my tongue while brushing my teeth. What could cause this? I attached a picture as well. Any treatment needed? Thanks for your time.

Respectfully ,


Hi Scott,

From what I can see, it doesn't appear to be any big problem. I would keep a watch on it and if it doesn't go away in 10-14 days, I'd get in to your dentist and have it checked. Most likely it is just from some minor trauma under your tongue.
