To heal a canker sore fast, several effective methods and remedies can be used to relieve pain and speed healing, though complete overnight cure is unlikely.
Fast Healing Methods for Canker Sores
- Saltwater or Baking Soda Rinse: Dissolve 1 teaspoon of salt or baking soda in 1/2 cup of warm water. Swish in the mouth for 15-30 seconds and spit out. Repeat several times a day to help dry out and reduce inflammation of the sore.
- Hydrogen Peroxide: Dilute 3% hydrogen peroxide with equal parts water, then use a cotton ball to apply directly on the sore or rinse the mouth. This helps clean the sore and reduce bacteria, supporting healing.
- Milk of Magnesia: Apply a small amount directly to the sore a few times a day. It neutralizes acids and coats the sore to reduce irritation and pain.
- Over-the-Counter (OTC) Topical Gels: Use gels containing lidocaine or benzocaine to numb pain, or corticosteroid ointments to reduce inflammation and promote faster healing.
- Ice Application: Ice wrapped in cloth placed on the sore can numb pain and reduce swelling, especially effective for lip sores.
- Natural Remedies: Applying coconut oil (antimicrobial and anti-inflammatory), aloe juice, or onion juice may reduce pain and support healing.
Additional Tips
- Avoid acidic, spicy, or abrasive foods that irritate the sore.
- Use mouthwashes without alcohol to prevent irritation.
- Zinc lozenges or vitamin B complex supplements might help if deficiencies are contributing to canker sores.
- If sores are persistent, large, or extremely painful, consult a healthcare provider for prescription treatments like corticosteroid mouth rinses.
Although these methods can reduce healing time and discomfort, canker sores generally take 1-2 weeks to fully heal naturally.
