How Are Canker Sores Treated

Most canker sores will heal on their own in a few days to a couple of weeks. While you’re waiting for them to disappear, you can take an over-the-counter pain reliever like ibuprofen or acetaminophen for the pain.

Be careful when you brush your teeth. Brush and rinse with toothpastes and mouthwashes that don’t contain SLS. And avoid brushing the sore itself with a toothbrush, which will make it worse.

If you have canker sores that do not get better after a few weeks, if the sores keep coming back, or if they make you feel so sick that you don’t want to eat, call your doctor or dentist. He or she may prescribe a topical medicine or special mouthwash to help heal the sores.

For medicines that are applied directly to the sore, first blot the area dry with a tissue. Use a cotton swab to apply a small amount of the medicine, and don’t eat or drink for at least 30 minutes to make sure it isn’t washed away.

They can certainly be a pain, but in most cases canker sores aren’t serious and should go away on their own.

What Causes Canker Sores In Your Mouth

Canker sores are commonly caused by trauma like biting the inside of your cheek, burns, allergies, or sensitivities. They may have other causes as well. However, canker sores are not contagious.

Certain conditions may make you more prone to them. These can include:

  • a weakened immune system because of illness or stress
  • hormone changes, such as menstruation
  • a vitamin deficiency, especially of folate and B12

Cold sores are caused by the herpes simplex type 1 virus . Outbreaks may also be accompanied by mild, flu-like symptoms, such as low fever, body aches, and swollen lymph nodes.

This virus can be dormant inside of your body. Sores may appear when the virus reactivates and last for weeks, according to 2021 research. This can occur when the immune system is weak or during times of stress.

Outbreaks are more common if you:

  • are under stress
  • are ill or have a weakened immune system
  • have had too much sun exposure
  • have a break in the skin of your mouth

The virus that causes cold sores is contagious and can be spread through contact with cold sores. It can be spread through kissing, sharing food, or sharing cosmetics. It is also possible to catch HSV-1 when sores cannot be seen.

Genital herpes, caused by the herpes simplex type 2 virus , can look similar in appearance to cold sores. Both viruses may be spread through sex without a condom or other barrier method if you or your partner has an active outbreak.
