In short
The mouth is an important part of the body that allows for taking in food and drink, breathing, starting digestion, speaking, singing, and showing emotion. Any problem that affects the mouth can make it hard to eat, drink, or smile. Common mouth problems include cold sores, canker sores, thrush, leukoplakia, dry mouth, gum or tooth problems, and bad breath. Treatment for mouth disorders varies depending on the problem, and if a mouth problem is caused by some other disease, treating that disease can help.

Description
Your mouth is one of the most important parts of your body. It has many different functions. It allows you to:
- Take in food and drink
- Breathe in air
- Start digestion, with your teeth chewing the food you eat and your salivary glands releasing saliva to help break down the food
- Speak and sing
- Show emotion, by smiling or pouting
Any problem that affects your mouth can make it hard to eat, drink, or even smile. Some common mouth problems include:
- Cold sores - painful sores on the lips and around the mouth, caused by a virus
- Canker sores - painful sores in the mouth, caused by bacteria or viruses
- Thrush - a yeast infection that causes white patches in your mouth
- Leukoplakia - white patches of excess cell growth on the cheeks, gums or tongue, common in smokers
- Dry mouth - a lack of enough saliva, caused by some medicines and certain diseases
- Gum or tooth problems
- Bad breath
Treatment for mouth disorders varies, depending on the problem. If a mouth problem is caused by some other disease, treating that disease can help. It is also important to keep your mouth clean and healthy by brushing, flossing, and not using tobacco.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
