The usual healing period for canker sores is about a week or two. But given that they are pain causing, here are a few tips to help you speed up the healing process as well as prevent the spread of the infection.

Use over-the-counter gels or patches
To prevent the ulcer from being aggravated by eating acidic or spicy food, one can try the application of topical over the counter gels or paste directly on the canker sore. These are also available in the form of special patches or bandages which can easily be stuck to the inside wall of the mouth and protect the canker sores effectively.

Use an antiseptic mouth rinse
All you have to do is make sure your mouth rinse has antiseptic properties so that when you use it for rinsing it can help with numbing the insides of the mouth.

Use salt for a mouth rinse
If you want a more natural substitute for over-the-counter mouth cleaners, then you use a simple salt solution that will help promote healing. However, if the canker sores are severe, you may be asked to use both for effective healing.

Always practice dental hygiene
It is important to take care of your mouth and ensure that the canker sores do not get damaged when you want to speed up the healing process. It is best to use soft brushes as compared to the hard ones because they help in maintaining good oral health as well as prevent the further infection of the sores.

Vitamin B-12 supplements for better oral care
Vitamin B-12 has a major role to play in red blood cell creation, which, in turn, supports the smooth functioning of the brain as well as the nervous system. Some studies have shown that the intake of Vitamin B-12 supplements promotes pain reduction for canker sores, and also helps in controlling the outbreaks and number of ulcers occurring in a month.

Have honey with chamomile tea
Both chamomile and honey have been well known to have various health benefits, and the same applies to the treatment of canker sores as well as it aids in the reduction of pain and inflammation. Since there is no strong evidence that it completely treats the ulcers, this is just a natural remedy that can part of your regular treatment plan without any hindrance.

Foods that need to be avoided
Foods that are salty, spicy, or acidic should be avoided because they easily tend to irritate the canker sores and hinder the healing process. Food that is hot as well as has rough edges like toasted bread and such should not be consumed when you have these types of sores.

Use aloe vera
One of the best ways to soothe irritation of these canker sores is to use aloe vera. They also help with reduction in pain and inflammation. Aloe vera is also safe to apply in the inner linings of the mouth.
