What surface of the tongue
are they on? The top part of the tongue
, or the underside? Look up pictures of "geographic tongue
" because that occurs on the top part of the tongue
. If it is on the bottom, it could be some canker sores because they occur on these spots. Either one, it would just be palliative treatment. Use some numbing gel - all your dentist will give you is, at most, a steroid rinse.
See if it goes away within 7 days. If it doesn't, then go to your dentist.
