How to get rid of canker sores

A canker sore is small ulceration, often painful, found in the mouth. There is no radical treatment to treat a mouth ulcer since it disappears after a few days.

Whether your canker sore is located on the gums, in the throat, on the palate, or the tongue, you can reduce the discomfort and promote the healing of your canker sore with an effective treatment such as:

• a local anesthetic treatment that relieves the pain associated with the mouth ulcer. These are most often gingival creams or gels;

• you will also find tablets or lozenges to suck ;

• finally, antiseptic mouthwash remains the treatment of choice in case of mouth ulcers.

Good to know: a canker sore is not contagious, but it can be confused with oral herpes. However, this oral infection rather develops around the mouth and not inside.

To treat my canker sores, what miracle remedies exist?

Some natural products are also known for their anesthetic property to soothe the pain. If you prefer to treat yourself naturally, you can make your home treatment for canker sores.

• Honey is a grandmother’s remedy known to cure canker sores. Antiseptic allows for reducing discomfort.

• The use of baking soda in mouthwash is also recommended in the treatment of canker sores.

• Clove essential oil is a treatment that provides quick but fairly short-lived relief for canker sores.

If your canker sore is painful, these treatments are quick enough to relieve your pain. However, avoid the use of grandmother’s remedies in your child if he has canker sores and prefers to consult a pediatrician to receive medical advice and appropriate treatment.


Good to know: lemon is not very useful in the treatment of a canker sore. So, there is no need to bite a lemon to heal yourself, it would rather increase your discomfort.
