White spots on children’s teeth can be improved by applying fluoride and resin restoration, but cannot be completely treated. White spots on children’s teeth are generally considered to be white patches on teeth due to decalcification of hard tissues of the teeth, which cannot be completely treated because there is no way to make the calcium ions return to the teeth by means of treatment at present. 1. Fluoride application: If it is a mild case of white patches and there is no damage to the enamel of the teeth, the treatment can be improved by applying fluoride locally. 2. Resin restoration: In case of moderate or severe white spots on teeth with slight tooth chipping, resin material can be used for filling to improve the white spots to a certain extent. During the treatment, you should follow the instructions of professional doctors to prevent any adverse effects. In daily life, we also need to pay attention to prevention, so that children develop good brushing habits, reduce or avoid drinking carbonated beverages, to avoid acidic substances to stimulate the hard tissue of the teeth, resulting in decalcification, and ultimately cause white spots.
