Make sure not to ingest or lick off the honey with your saliva even though the ulcer is inside the mouth. It is of utmost importance to keep the applied honey intact for a few hours. To make sure the honey is always touching the ulcer, keep applying it every few hours. 

The antimicrobial properties of honey help in repairing any open wound quickly. Honey also protects the wounded area from infections.

3. Baking soda paste

Mix equal amounts of baking soda and water and make a thick paste. Apply the mixture on the mouth ulcer and let it dry out. Once the baking soda and water mixture dries out, rinse your mouth thoroughly with water and make sure to gurgle as well.

Repeat the procedure thrice a day. The baking soda and water mixture is usually used in home-cleaning solutions. However, it also cures mouth ulcer faster and reduces the pain significantly. It neutralizes the acidity of the ulcer, eventually treating the wound.

4. Saltwater

Take a tablespoon of salt and mix it in a glass of warm water. Gurgle thoroughly with this saltwater mixture. Once done, you may gurgle further with plain water to remove the salty aftertaste from the mouth.

This procedure is used to soothe the pain and discomfort you might experience during mouth ulcer. The antiseptic properties of salt further disinfect the sore ulcer and calm the area. 

5. Toothpaste

Any good toothpaste contains antimicrobial properties in its composition that are capable of reducing the swell and pain of the mouth ulcers. Using a Q-tip, apply the toothpaste on the ulcer. Make sure you cover the entire region affected by the ulcer. Leave it on the area for a few minutes before rinsing it off. Repeat the process regularly until the whiteness of the sore disappears. 

Note: Applying toothpaste on the sore can be pretty painful. This pain can be reduced through the application of aloe vera gel on the spot. 

6. Garlic

Garlic contains a certain kind of compound known as the Allisin compound. This compound is responsible for the antimicrobial properties in garlic, which prevents infection. Cut a clove of garlic in halves and dab it gently on the ulcer spot for at least 2 minutes. Once done, rinse your mouth with plain water to get rid of the strong garlic odour. Repeat this process for two to three times a day. 

7. Orange juice

A great source of Vitamin C, orange has certain properties that are capable of preventing and aiding mouth ulcers. Eating an entire clove of orange might prove to be uncomfortable and painful while suffering from mouth ulcer, so we suggest drinking a glass or two of freshly squeezed orange juice every day until it disappears. Orange juice boosts the immunity of a person and enables the body to fight against infections and diseases.
