As you age, everyday wear and tear can affect your teeth, but there are many ways to keep them healthy. Follow these tips to maintain a great smile: Your teeth are strong, but chewing, grinding, and biting can wear down the enamel, the hard outer layer. Avoid chewing ice or hard foods to prevent chips and breaks. Poor bites and nighttime grinding (bruxism) can also wear down teeth and may require orthodontic work or a night guard. Plaque, a type of bacteria, constantly forms on your teeth. If not removed, it can cause gum soreness, swelling, and bleeding, and even infections that damage the bone. Regular dental check-ups and cleanings are essential. Brush twice a day, floss daily, and quit smoking if you do. Saliva helps clean teeth and protect against decay, but as you age, your mouth may become drier, increasing the risk of decay. Drink more water, hold it in your mouth before swallowing, and consider sugarless candy or gum. If medications are causing dryness, consult your doctor. Worn enamel, gum problems, and decay can make teeth sensitive to hot, cold, or hard brushing. Good dental care is crucial. Your dentist can recommend treatments for sensitivity. Acidic drinks and foods can erode enamel. Avoid swishing them in your mouth and follow with milk or cheese. Eat sugary and starchy foods with meals to increase saliva production. Aging increases the risk of oral cancers. Prevent this by avoiding smoking, drinking alcohol in moderation, and using lip balm with sunscreen. Regular dental check-ups can catch early signs like sores, red or white patches, and changes in your mouth.
