White spots on teeth can be caused by a variety of factors, including an acidic/sugary diet, poor dental hygiene, tooth trauma, certain medications, fluorosis, and enamel hypoplasia. White spots can be an early sign of tooth decay, so it's important to identify the cause and administer the proper treatment. Treatment options for white spots on teeth include enamel microabrasion, bleaching, and composite resin. Maintaining good oral hygiene, avoiding sugary and acidic foods, and adjusting fluoride use can also help prevent white spots on teeth. If you are noticing white spots on your teeth, it's best to consult your dental professional to determine the underlying cause and appropriate treatment.
