Tooth decay can be avoided through proper oral hygiene, a healthy diet, and regular dental checkups. Brushing teeth twice daily and using dental floss helps remove food debris that can lead to plaque and decay. Seeing a dentist regularly allows early detection and treatment of decay before more serious issues arise. Following a diet low in sugars and acids protects teeth, as these can increase decay risks. Proper care and prevention can help avoid the pain, discomfort, tooth loss and unattractive smiles caused by tooth decay.
