My tougue breaks out in white bumps on the tip of my tougue in a circle.

Geographic tongue : It is most likely geographic tongue. It's nothing to worry about. If it doesn't go away or becomes painful see your dentist. If you are concerned make an appointment with your dentist to make sure this is the case. Hope this helps!

See your Dentist: White bumps on the tongue could be caused by oral thrush, leukoplakia, oral lichen planus, canker sores, etc. Some may require further assessment, tests and your Dentist may book a follow-up appointment or refer you to a specialist to determine a diagnosis. Take care.
