How do you get rid of mouth ulcers?

A mouth ulcer may appear as an open sore on the lip or mouth. Nutritional deficiencies and stress are the two most common causes of mouth ulcers. 


Reducing stress and meeting daily micronutrient requirements through supplements or diet are essential for combating mouth ulcers. Most home remedies for ulcers use ingredients commonly found in the kitchen. You can also apply a few home remedies to help the recovery process. 


You can use simple ingredients to get rid of mouth ulcers at home, such as : 



Honey is antimicrobial. It possesses wound-healing and antibacterial properties, making it an effective weapon against mouth ulcers. It will help to moisturize your mouth while keeping it from getting dry, quicken the natural healing process of the mouth ulcer and keep it infection free. It also reduces irritation and swelling. Dab some raw honey directly on your ulcer. You can also mix it with turmeric. Apply this simple remedy every 2-3 hours.


Virgin Coconut Oil

Coconut Oil treats ulcers naturally due to its extensive antimicrobial components – the medium-chain fatty acids. It is also an anti-inflammatory compound and an analgesic. These properties will reduce the swelling and pain you experience from the mouth ulcer.

*You can dab a little bit of this oil on the mouth ulcer, leave it on, and keep reapplying it every few hours.


Natural Orange Juice

The key to this remedy is getting a lot of vitamin C into your body, as vitamin C deficiency can result in mouth ulcers. Also, vitamin C boosts your immune system and helps your body fight all kinds of infections, including mouth ulcers.

*Drink two glasses of natural orange juice a day and repeat until the mouth ulcer heals.


Baking Soda

Baking soda is usually used around the house to clean and deodorize. It also is an excellent home remedy for mouth ulcers. It eases the pain and speeds up healing by neutralizing the ulcer acids.

*Mix the water and baking soda to form a paste. Apply this on the mouth ulcers using your fingers. Let it dry for a few minutes. Rinse your mouth with water and gargle.



Toothpaste also has antimicrobial properties, making it one of the effective home remedies for mouth ulcers. It also creates a cooling effect that can relieve the burning sensation that you experience and provide comfort. Choose mild toothpaste that is free from SLS. After applying toothpaste to the ulcers, allow it to stay on for a couple of minutes before rinsing it off. Continue to do this for as long as is required.
