White spots on teeth do not usually require calcium supplements. White spots on teeth are usually not caused by calcium deficiency, and there is no need to take calcium supplements in a hurry to avoid affecting the development of teeth. White spots may be caused by enamel hypoplasia, and there may also be dental caries or dental fluorosis, which requires timely medical examination to understand the cause and then treat the symptoms. If enamel hypoplasia occurs, you can promptly consult a doctor for examination, use fluoride toothpaste, and also need to regularly consult a doctor for dental care, which can effectively alleviate the symptoms. If caries is present, filling treatment or root canal treatment (where pulpitis occurs) is required to avoid aggravation of caries. For fluorosis, veneers or crowns can be used. If you find white spots on your teeth, it is recommended that you visit a hospital to have the cause of the problem determined and treated by a doctor.
