Helpful Home Remedies For Canker Sores

A canker sore doesn’t usually require a visit to your doctor, and if a sore only causes minor pain, you might forgo treatment altogether. But when a canker sore sparks a nagging ache, or if the sore makes it difficult to talk or eat, you need fast relief and prompt healing. Read on to learn about canker sores and home remedies for canker sores.

What Are Canker Sores?

A canker sore, or aphthous ulcer, is a typical yet painful type of mouth ulcer. These sores frequently present themselves inside the lips and cheeks as white/yellow lesions alongside inflamed red soft tissue.

Canker sore symptoms include

  • a small white or yellow oval-shaped ulcer in your mouth
  • a painful red area in your mouth
  • a tingling sensation in your mouth

In some cases, other symptoms may also be present, including fever, swollen lymph nodes, and not feeling well.

Canker sores are not contagious and can normally be cured within 1-3 weeks without any treatment. Generally, the pain from these sores will go away in 7-10 days; however, depending on severity, it may take up to 6 weeks for a full recovery.

Treatment For Canker Sore

Although canker sores often heal on their own, making the right lifestyle adjustments can significantly reduce discomfort and speed up healing time. To prevent bacterial infection and speed up the healing process, it is important to make tooth brushing and flossing part of your daily routine. Additionally, you should also abstain from consuming spicy foods as they can delay recovery. Pain can be extreme at times. To reduce the pain, you may try gargling with mouthwash or salt water; though it might feel uncomfortable initially, this method has been shown to provide relief.

Some ingredients in over-the-counter topical products can help relieve and heal sores, including

  • benzocaine (Orabase, Zilactin-B, Kank-A)
  • hydrogen peroxide rinses (Peroxyl, Orajel)
  • fluocinonide (Vanos)

If your dentist or physician prescribes it, you may find relief with a powerful antimicrobial mouthwash like Listerine. Antibiotics such as oral pills containing doxycycline (Monodox, Adoxa, Vibramycin) and mouthwashes are also available to help reduce the risk of infection. Corticosteroid ointments including hydrocortisone hemisuccinate and beclomethasone can provide soothing for inflammation and pain. You could also explore prescription-strength rinses that contain dexamethasone or lidocaine for additional relief.

Home Remedies For Canker Sores

Applying ice or tiny amounts of milk of magnesia to your sores can help relieve pain and promote healing. Rinsing your mouth with a mixture of warm water and baking soda (1 teaspoon per 1/2 cup of water) can also help with pain and healing.

According to NCBI, honey is an incredibly effective remedy for canker sores. To avoid further irritation, a topical gel may be applied directly to the sore. Alternatively, special patches or bandages can also be used to protect the canker sore.

To alleviate the pain caused by canker sores, take vitamin B12 supplements and drink chamomile tea which is believed to possess anti-inflammatory characteristics. You may also rinse your mouth with it or put a wet tea bag directly on the sore. 

For additional relief, try mixing honey into the mixture of chamomile tea as its antiseptic properties are well known.

Alleviate discomfort and reduce inflammation of canker sores with the application of aloe vera gel. Clove oil, one of the oldest remedies for mouth ulcers, may also be applied using a cotton ball soaked in clove oil directly onto the sore to bring relief.
