How To Get Rid Of A Canker Sore?

Canker sores, also known as aphthous ulcers, are small, painful ulcers that develop on the inside of the mouth, lips, or throat. While canker sores are not contagious or dangerous, they can cause discomfort and irritation, making it difficult to eat, speak, or brush your teeth. Fortunately, there are various ways to get rid of canker sores, ranging from simple home remedies to medical treatments.

In this article, we will explore some of the most effective methods to treat canker sores.

Home Remedies for Canker Sores

Saltwater rinse

One of the simplest and most effective ways to alleviate canker sore pain is to rinse your mouth with a saltwater solution. Mix a teaspoon of salt in a cup of warm water and swish the solution around your mouth for 30 seconds, then spit it out. Repeat the process several times a day to soothe the sore and promote healing.

Baking soda paste

Another home remedy for canker sores is to make a paste out of baking soda and water. Mix a small amount of baking soda with water to form a thick paste and apply it directly to the sore. Leave it on for a few minutes before rinsing it off with water. Baking soda has alkaline properties that can help neutralize the acids in the mouth and reduce inflammation.


Honey is a natural antibacterial and anti-inflammatory agent that can help heal canker sores. Apply a small amount of honey directly to the sore and leave it on for as long as possible. Repeat the process several times a day until the sore has healed.

Aloe vera gel

Aloe vera is another natural remedy that can help soothe canker sores. Apply a small amount of aloe vera gel directly to the sore and leave it on for 10 to 15 minutes before rinsing it off with water. Aloe vera has anti-inflammatory and antibacterial properties that can speed up the healing process.

Medical Treatments for Canker Sores

Over-the-counter medications

There are various over-the-counter medications available that can help alleviate canker sore pain and promote healing. These include oral gels or creams containing benzocaine, which can numb the sore and reduce discomfort. Some products also contain anti-inflammatory agents such as hydrocortisone or amlexanox, which can help speed up the healing process.

Prescription medications

If over-the-counter medications are not effective, your doctor may prescribe stronger medications to treat canker sores. These may include corticosteroids, which can help reduce inflammation and promote healing, or antimicrobial mouthwashes, which can help kill bacteria and prevent infection.

Laser therapy

Laser therapy is a relatively new and promising treatment for canker sores. This involves using a low-level laser to target the sore and promote healing. While the exact mechanism of action is not fully understood, laser therapy has been shown to reduce pain and promote healing in some patients.


Canker sores are painful and annoying, but fortunately, there are several ways to get rid of them. If you experience recurrent or severe canker sores, it’s best to consult your doctor or dentist for a proper diagnosis and treatment plan. However, for occasional and mild cases, home remedies and over-the-counter medications can provide relief and speed up the healing process. Remember to maintain good oral hygiene and avoid triggers that may cause canker sores, such as acidic or spicy foods, stress, and trauma.
