My right tonsil is larger then other one is it normal? i also have an erupting right third molar sometimes eating spicy foods gives me a slight burning feeling on right side only at the back of my tounge and throat is it normal?

It is not feasible to provide a meaningful opinion without examining you. If the size is stable, you may watch and wait. If the size of the larger tonsil increases by more than 50%, an ulcer forms, the tonsil bleeds, you get fever, lose weight, lymph nodes in the neck become large, see a doctor. Wish you good health!

We are not perfectly symmetric. Not unusual to have 1 tonsil larger than the other.Question is threaten infection or is tonsil size causing other anatomic abnormalities. Please ask both your Physician snd your Dentist to examine as each has a different sphere of expertise/attention.
