Preventive dentistry is the discipline of looking after the gums and teeth and practicing good oral hygiene to keep them safe. Cavities, gum infections, enamel wear, tooth loss, and other problems are all avoided. We have become more susceptible to oral diseases as a result of years of processed diet, so preserving them has become extremely necessary. Oral disease prevention has become simpler due to advances in dentistry. Oral hygiene should be practiced starting at a young age. Brushing and flossing twice a day is the most basic type of preventative dentistry. Another means of avoiding oral diseases is to see a dentist every six months. The preventive dentistry protocol benefits children the most because it helps their newly grown adult teeth to come in strong and healthy. Preventive dentistry seeks to stop dental diseases from starting and progressing, as well as limit their complications and provide recovery.
