<human>: My two yr old son has decalcification on his top teeth.  I have been brushing his teeth up to six times a day.  I have noticed a tiny spot on two of his teeth.  The dot is located on the white spot it is the color of his tooth its just located on the spot.  I dont know if its a cavity or if its a sign of remineralization.  How can u tell if you teeth are remineralizing?
<bot>: Hello:)Welcome to Chat Doctor. Excessive tooth brushing is contraindicated. You will erode the enamel with this. Just brush twice, once in the morning and once before bed. You can make him rinse with a saline mouth wash once a day. White spots can be sign of decayed teeth or fluoride discoloration. See your dentist for a clinical examination. Remineralization in teeth can happen, but it is very minimal. Regards.
