There is not a definite cure of a mouth ulcer in dentistry, but there are ways we can prevent them, hence saving ourselves from dental pain.
Maintenance of oral hygiene and eating properly are two of the several ways to avoid a mouth ulcer.
1. Proper oral hygiene- Brush twice a day with a fluoride toothpaste. Floss once daily, especially before bed. Incorporate a mouthwash too. Avoid SLS in your toothpaste if you are prone to mouth sores.
2. Eat a healthy diet including vitamins, minerals and probiotic foods. (Vitamins B6, B12, C; zinc and iron). Avoid irritant foods like spices and excessive oil.
3. Avoid stresses or trauma to the oral cavity, like ill-fitted dentures or braces. Visit your dentist if you have a sharp tooth. Avoid eating food which is too hot.
4. Avoid any medications that may cause ulcers.
5. Avoid highly citrus fruits like pineapple, strawberries, lemons, oranges if you have a tendency of mouth ulcers. Maintain a more alkaline diet for proper oral health.
6. Quit any bad habits like smoking, tobacco chewing or alcohol.
7. Incorporate plenty of fluids, especially water in your routine to flush bacteria and waste products like free radicals away.
You basically have to maintain a healthy lifestyle to avoid such oral diseases. Remember to visit a doctor, if your ulcers persist for more than two weeks. Also, eliminate the existence of any underlying disease which may cause the occurrence of mouth sores.
