Live a regular life Get enough quality sleep. Find ways to avoid accumulating fatigue and stress. Adequate hydration prevents dry mouth. Be careful not to breathe through your mouth. Make gargling and brushing your teeth a habit to maintain oral hygiene. If you wear dentures, keep them clean using chemical cleaning agents or similar methods. Chew thoroughly to stimulate saliva production. Dental care Have your teeth checked at the dentist to see if there are any underlying causes of chronic irritation. Receive brushing instruction Treating cavities If dentures or orthodontic appliances don't fit properly, they will be adjusted. How to treat mouth ulcers If you develop a canker sore, it's important to treat it appropriately to prevent it from worsening. However, if you have any concerning symptoms, you should see a dentist as soon as possible. Basic countermeasures The following are some basic ways to deal with mouth ulcers: Thorough brushing removes plaque, which is a mass of bacteria. Use mouthwash to suppress bacterial growth and maintain oral hygiene. If you suspect you have a lot of tongue coating *, please visit a dentist to have it removed. If anemia or nutritional deficiencies are the cause, focus on consuming nutrients that are often lacking while maintaining a balanced diet. To prevent irritation, avoid consuming spicy, sour, salty, and hot foods. Avoid drinking alcohol and smoking. *In normal eating habits, the tongue's self-cleaning mechanism works, and tongue coating does not usually increase. However, in elderly people, those with impaired tongue function due to conditions such as stroke, or those who only eat soft foods, tongue coating may accumulate. In such cases, go to the dentist as soon as possible. Typical mouth ulcers usually heal on their own within one to two weeks. If symptoms persist for more than two weeks, or if you experience any of the following symptoms, please see a dentist as soon as possible. The redness is getting worse. The swelling is getting worse. The area where symptoms appear is getting larger. The symptoms appear and disappear. Pus is coming out. The pain is severe and is interfering with daily life. Symptoms are also appearing outside the oral cavity. How to prevent and treat mouth ulcers in children Basically, the same preventative measures and treatments as for adults are applied. However, unlike adults, children tend to be careless about the condition of their mouths. Parents need to be careful to prevent injuries to the mucous membranes and insufficient brushing. Common concerns about mouth ulcers (Q&A) Mouth ulcers are a common ailment in our daily lives. A dentist will answer your questions about mouth ulcers. Are mouth ulcers contagious? Mouth ulcers can be caused by bacteria, fungi, viruses, and other factors. In such cases, they are infectious diseases and can be transmitted to others. Are there mouth ulcers that don't cause pain? Mouth ulcers can manifest in various ways; some are painful, while others are not. However, the absence of pain does not necessarily mean there is no problem. In particular, oral cancers such as tongue cancer may not cause pain in their early stages, so if you have any concerning symptoms, please consult a dentist.
