How to Get Rid of a Cold Sore on the Inside of Your Mouth

• 1

  Use an anti-bacterial mouthwash. This will help kill bacteria inside the mouth, reducing the chances of a secondary infection in the cold sore. You should rinse with the mouthwash several times a day.

• 2

  Make a paste of baking soda and warm water and apply it to the cold sore with a cotton swab to help ease the pain. The mixture can also be used as a mouth rinse. You should apply this mixture a few times a day if possible.

• 3

  Use over-the-counter products such as Abreva, Anbesol or Orajel. With a cotton swab, apply the product to the cold sore a few times a day. This will help ease the pain, redness and swelling. The cold sore should disappear within a week to 10 days.

• 4

  Eat a healthy diet. Nutrition is the key to great health, and building up your immune system can help fight cold sores. Fresh fruits and vegetables such as broccoli, cauliflower and cabbage all help cleanse your body of toxins that can make you more susceptible to viral infections.

• 5

  Keep your stress levels down. Cold sores can appear if you are under stress or if there are significant changes in your hormone levels.
