I have little bumps that looks like taste buds in the inner lips... can someone please tell me what it is?

Inner lip bumps: They can be a combination of minor salivary glands and Fordyce spots which are small sebaceous glands. To know for sure, you will have to show them to a dentist.

Bump in mouth: in the inner lips may be caused by a simple possible conditions like foods irritation. In most cases they will resolve on their own. However, you still need to see a doctor if the bumps persists for a long period of time or becomes worse over time. Good luck.

Reaction: Wether it's allergic or traumatic irritation to the mucosal tissues from certain foods or meds. Or to dental appliances and instruments . If persists more than two weeks see a doctor .
