Also known as canker sores, mouth ulcers can be a very painful dental issue to deal with. If you have them, you know how uncomfortable it can be to eat and talk when you have a mouth ulcer. While the causes of theses sores vary from person to person, there a few common triggers to be aware of.

Highly Acidic Foods

Citrus fruits such as oranges or pineapples that are high in acid can contribute to mouth ulcers. Spicy foods may also aggravate them, so it's best to drink a lot of water and avoid these types of foods if you have one.

Smoking or Tobacco Use

Smoking cigarettes may not cause your canker sore, but it will definitely irritate it and may prolong healing. Tobacco products that you chew do contribute to mouth ulcers and can even be the cause. Quitting smoking may alleviate your condition if you suffer from chronic mouth ulcers, and your team at 50th and France Dental Care is always happy to support you in quitting.


Stress has a lot of negative impacts on our bodies, including contributing to canker sores. Finding ways to relieve your stress such as exercising or self-care like massage can help to eliminate stress.

Braces and Other Oral Appliances

Many mouth ulcers are the result of braces that have just been adjusted or other oral appliances such as a denture that may no longer be fitting properly. A little wax applied to braces can help protect your soft tissues, while a reline may be in order to help your denture fit properly again.
