What are some treatments for mouth sores?

Some treatments for mouth sores include avoiding hot, spicy, salty and sugary foods, alcohol and tobacco, gargling with salt water, eating ice cubes and taking pain medicine, such as acetaminophen, according to Healthline. Usually mouth sores disappear between 10 and 14 days, but some last as long as six weeks.

There are also ways to prevent mouth sores from forming in the first place, says Healthline. Avoiding really hot foods and drinks and chewing slowly while eating may prevent mouth sores. Sufferers of mouth sores can use a soft toothbrush and make sure to brush regularly. Other preventive actions include taking a vitamin B supplement and drinking enough water.
