These little bumps suddenly become evident. In many cases, a bump on the roof of the mouth will disappear of its own accord but some may need the attention of a dentist or doctor. The most common, and most likely, causes are:
– Canker sores which normally disappear in a few weeks
– Scar tissue from trauma or injury including cuts, irritation and tobacco use
– Mucoceles are small cysts that form bumps and usually heal without treatment
Rarely, hyperdontia, which causes people to “grow too many teeth”, may be the cause and the extra tooth will have to be extracted. Other causes of bumps on the roof of the mouth are detailed at https://www.medicalnewstoday.com/articles/323063.php
