Yikes! Canker Sores 101 | Best Dentist San Diego

When you have a canker sore, eating, drinking, and talking can be very uncomfortable and even painful. Maintaining a healthy oral hygiene routine can also be challenging when you have a sore in your mouth. However, you must continue with your daily routine as part of your healing process. 

What is a canker sore?

Typically, canker sores are small, reddish lesions. They are located on your tongue, on the sides of your mouth, and at the base of your gums. In some cases, a sore may appear yellow or white in the center. In addition, you may feel a burning or tingling sensation a day or two before the sores appear.

A canker sore is different from a cold sore (also referred to as a fever blister). Cold sores usually appear on the outside of your lips or at the corners of your mouth.

Where do they come from?

Injuries are one of the most common causes of canker sores. This can be caused by biting your lip or cheek due to stress, an injury from sports, or even brushing vigorously. Some individuals are sensitive to toothpaste containing sodium lauryl sulfate, which may result in sores. Certain foods may also cause canker sores. Sores are known to be triggered by foods such as chocolate, eggs, nuts, and spicy foods. Occasionally, an unbalanced diet may be to blame, especially when zinc or vitamin B-12 deficiency is the underlying cause.

Can you tell me what I can do?

Maintaining a healthy mouth is your best defense. Keeping your teeth clean means brushing twice a day and flossing every day. It may be tempting to avoid brushing your teeth when you have a mouth sore. However, this can lead to a buildup of plaque and bacteria. To help the healing process, keep your mouth clean and healthy. Alternatively, you can try a mouthwash formulated especially for mouth sores. There are also over-the-counter and prescription products you can use, such as Benzocaine, Fluocinonide, and hydrogen peroxide. You can also take nutritional supplements such as folic acid, vitamin B-6, vitamin B-12, or zinc. Consult our team if you are unsure or if the pain persists.

It is recommended to brush around sores gently but thoroughly. Most canker sores will heal within one week. Make an appointment with our dentist if you experience sores frequently or if they do not heal within one week. We will evaluate the severity of your sore and may recommend alternate treatments if necessary.
