Canker sores are a common condition that almost everyone experiences at least once in their lifetime. These small ulcers that appear inside the lips, cheeks, or under the tongue are not dangerous, but they can cause a burning sensation and discomfort when eating, drinking, or talking. The pain can become even more noticeable when consuming spicy, salty, or acidic foods.
Many people have long used baking soda as a simple home remedy to help soothe canker sores. Baking soda is a familiar household ingredient in many American homes, commonly used for cooking, cleaning, and personal care.
Here are two popular ways people use baking soda.
Method 1: Rinse Your Mouth with Baking Soda and Warm Water
This is the simplest method and works well for most people.
How to do it:
Prepare one cup of warm water.
Add about one teaspoon of baking soda.
Stir until completely dissolved.
Swish the solution around your mouth for 20–30 seconds, then spit it out.
You can repeat this several times throughout the day.
Many people believe this rinse helps clean the mouth and provides a more comfortable feeling around the affected area.
Method 2: Make a Thick Baking Soda Paste
Some people prefer applying baking soda directly to the canker sore.
How to do it:
Mix a small amount of baking soda with a few drops of water.
Stir until it forms a thick, cream-like paste.
Use a clean cotton swab to gently apply it to the sore.
Leave it on for a few minutes, then rinse your mouth with clean water.
This method is commonly used for small sores that are easy to reach inside the mouth.
Why Do So Many People Choose Baking Soda?
Baking soda has mild alkaline properties and has long been used in a variety of home personal care remedies. Some people find that their canker sores feel less uncomfortable after using it, especially when combined with good oral hygiene practices.
However, results may vary depending on the individual and the underlying cause of the canker sore.
Things to Keep in Mind
Avoid very spicy or extremely hot foods while dealing with canker sores.
Drink plenty of water every day.
Include more vegetables and fruits in your diet.
Maintain good oral hygiene.
If the sore lasts for several weeks, keeps coming back frequently, or shows unusual symptoms, consult a healthcare professional.
Baking soda is a familiar and easy-to-find household ingredient. While it is not a miracle cure, it remains a simple remedy that many people like to keep in mind when dealing with the discomfort of canker sores in everyday life.
