I have swollen taste buds but there is no pain. what does this mean?

Too little info: Without more information and without seeing your tongue, this question cannot be properly answered. You need to have this looked at by a dentist to get a proper answer.

Not uncommon : Swollen taste buds or papillae can be a normal occurrence. There can be single, several , or even patterns of enlarged bumps on tongue. Usually not a serious condition. However your dentist can determine if you should be alarmed.
