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?
