Mouth sores can become an annoying problem for many people. Normally, they appear when we have low defenses, as certain bacteria take advantage of these circumstances to settle anywhere in the mouth they can and cause problems. Find out about some home remedies for mouth sores in this article.

Usually, these discomforts disappear in a short time, often between 10 and 20 days. It’s not often necessary to visit the doctor, as the body’s defenses immediately begin to heal the wounds.

However, sometimes these sores become more resistant and take longer than usual to disappear. On those occasions, we should seek professional help, because we may be dealing with a much more serious problem.

However, when it comes to mouth sores caused simply by an infection or a new prosthesis, for example, then we can resort to some home treatments that will help us to make them disappear in a short time. Have a look at some great remedies below:

Natural remedies for mouth sores?


Onions on a cutting board.
Evidence suggests that onion has components with anti-inflammatory capacity.


Onions are very useful natural products in the treatment of mouth sores, as they have large amounts of sulfur.

To help you treat this oral health problem, you should consume plenty of raw onion. Eating it mixed in salads is also a good option.


Basil is an herb with a pleasant aroma that, besides being very useful in the treatment of mouth sores, also helps fight bad breath.

It’s advisable to make an infusion by boiling half a liter of water with a bunch of basil branches. Later, let it steep and rinse your mouth by gargling with it. You should perform this procedure two or three times a day, preferably after having brushed your teeth as usual.

Peppermint oil

Some peppermint on a wooden tray


Peppermint oil has anesthetic and anti-inflammatory which is of great help to soothe the pain caused by mouth sores.

To obtain the desired effect, you only need to take a cotton swab dipped in this oil and rub it gently on the affected part.

Orange juice

Vitamin C strengthens our immune system. Because of this, it’s very important to include this juice in our diet on a regular basis.

Coconut oil

Some coconut.

Many people believe that another of the most effective natural remedies for mouth sores is coconut oil, although this isn’t scientifically proven. The best way of preparing it is by preparing mouthwashes and gargling at least three or four times a day.

Sage with rosemary

To prepare a mouthwash based on sage and rosemary, we simply take half a liter of water and boil it with two tablespoons of each of these herbs.

Let it boil for about five minutes, take it off the heat and let it stand. When the water is lukewarm, rinse your mouth three to four times a day.

This natural rinse can be very effective against the burning and pain that these mouth sores cause.
