Prevention of Mouth Ulcers

Aphthous ulcers damage the oral mucosa. Therefore, it is important to keep this mucous membrane healthy and prevent canker sores. Here’s how you can do this:

Maintain Good Oral Hygiene

Clean teeth and a clean mouth ensure a healthy oral mucosa. It also protects the mouth from viruses and bacteria that can cause mouth ulcers. Therefore, brush your teeth twice a day and do not neglect regular visits to the dentist.

Avoid Stress and Fatigue

Easier said than done, but stress and fatigue are significant triggers for the onset of canker sores. Modern life is very fast-paced, and stress and fatigue can build up more quickly than you think. Therefore, set aside time to relax regularly. When you are done with work, turn off your laptop or cell phone. Take a good book and a bath. Simply relax.

Canker sores usually disappear spontaneously within 14 days. The tips above can help speed up the healing process. If the canker sore in your mouth is larger than 1 cm, it may take longer.
