Canker sores can cause considerable discomfort around and inside the mouth. If you’ve ever had one of these painful ulcers, you know they can be stubborn to treat. Understanding what they are, how they appear, and why they occur can help you better cope with the situation. Here’s what you should know, including the importance of seeing a dentist for oral hygiene. 

What Are Canker Sores?

Also known as an aphthous ulcer, a canker sore is a small lesion that forms inside or near the mouth. It’s most likely to develop on the cheeks, lips, gums, soft palate, or beneath or on the tongue. Symptoms include general irritation or a burning feeling that develops before the sore is visible. You might also see a sore area that appears gray, white, or yellow and has a red surrounding. When minor, canker sores can heal within a matter of a couple weeks. But deeper, larger, and more painful sores can take up to six weeks to resolve.

Why Do They Happen Often?

Canker sores are common because there are many triggers that may cause them. Biting down on the affected area with a sharp tooth may be to blame, as can wearing dentures or braces. Some people develop an allergic reaction to sodium lauryl sulfate (SLS), the foaming agent commonly found in many toothpastes. 

Even eating certain irritating foods, like spice or acidic fruits, can cause a sore to develop. Smoking, stress, and trauma to the area through surgery or an injury may also be responsible. Some medical conditions, like celiac disease and Crohn’s disease, can leave some people more susceptible to canker sores.

How Is Oral Care Helpful?

Proper oral hygiene is vital to preventing canker sores. Brushing at least twice a day and flossing at least once keeps your teeth and gums clean, minimizing irritation from foods that might otherwise trigger a canker sore to form. You should also use a soft toothbrush to prevent scratches and damages associated with harsh, hard bristles. Look for a toothpaste free of SLS, and see your dentist for regular cleanings. If you’re prone to sores, your provider will assess their severity and may prescribe a topical ointment or rinse to speed the healing process and reduce discomfort.
