White dot on my tongue?

Maybe normal?: It may be normal or something else. If it does not go away in 2 weeks see a dentist for an evaluation.

Lots of things: A white dot may be normal may be abnormal. Most lesions of no great significance will resolve in 10-14 days. But if normal it likely will not dissappear. If it doesn't resolve in 2 weeks or is associated with any pain or swelling, see a dentist. It's likely nothing but impossible for us to speculate further without more info. Best of luck!
