- You can also apply the juice of an organic onion over the affected area.
10. Cayenne Pepper
Cayenne pepper has capsaicin in it, which can temporarily numb the nerves causing pain and provide quick relief.
- Apply a small bit of cayenne pepper directly onto the canker sore. It may cause some irritation at first, but it is highly effective for relieving pain.
- You can also try chewing or sucking on some candy that contains cayenne pepper.
With these home treatments, you can easily deal with painful and irritating canker sores in a fast and effective manner. If your canker sore does not go away, see your dentist as it can be a sign of a serious condition such as oral cancer.
