My daughter is 3 yrs old. She has a puss filled blister, boil, or something not sure. Its been there for a while. She doesnt complain of pain until I brush her teeth. Her front tooth is turnIng a slight grey color. What could be the cause? How do I treat it? Do I need a dr? Or a dentist?
Hayes she needs dentists attention as you mentioned tooth is turning into gray color it means a decay tooth with infection. Usually swelling or blister whatever if pus is Chat Doctor.  Its better you would have mentioned the tooth status whether it is mobile or not. Anyway it will be better if you consult the doctor. Hope I have clarified your query
