I have two white spots, like a bubble on the right side of my toung. what can that be?

Mucocele: Your description sounds like a mucocele. This is generally a benign condition that tends to spontaneously resolve on its own. It usually happens after minor oral trauma. Rarely, they can be chronic. Salt water rinses may help. Removal can be laser or surgical; if interested in pursuing either of these options, I'd advise seeing a dentist.
