Treat your mouth sores at home

Treat your mouth sores at home

At some point in our lives, we have all been plagued by that irritating mouth sore which seems to take forever to go away. Mouth ulcers (someimtes known as canker sores) arise from bacteria invading little injuries in oral cavities. Our immune system then mounts a response, causing inflammation at the sites of bacterial invasion. This inflammatory process is the culprit behind the pain and swelling associated with the mouth ulcer. Luckily, you don't need to see a dentist each time something like this comes up (quite literally)! Here some simple remedies which can chase them away! Do bear in mind that different remedies work better for different people; choose the one which best suits you.    


Salt/ salt water

Since mouth sores are caused by bacteria invading sites of injury in your oral cavity, it makes perfect sense to kill the bacteria with salt (well-known to have anti-bacterial properties). Many can vouch for its effect on reducing inflammation, but be weary of the sharp pain which comes with this remedy! If you are looking for a less painful method of dealing with your ulcer, consider gargling salt water (instead of directly applying salt to the ulcer) or using other remedies.



Oracort-E is a dental gel containing corticosteroid—a potent anti-inflammatory substance. Once applied over the ulcer, it also forms a “gel-like” structure, which protects the ulcer from further contact with food, bacteria or other substances found in the mouth. It has been found to be clinically effective at combating mouth ulcers and their associated symptoms, but do check with your doctor before using Oracort-E as it does carry certain possible side effects.  


Watermelon powder

If you've entered an Asian drugstore, you would probably have seen a small bottle labelled “watermelon powder” sitting on a shelf somewhere. Chinese medicine advocates the “cooling” effects of watermelon, which is what probably served as the original basis of this traditional remedy. It might not be the most effective at healing ulcers, but few can refute its ability to ease the pain that comes with having one.   



Some research has found that applying pure honey to mouth ulcers can help to reduce inflammation, thus reducing pain and the size of swelling. Though its effects are not a hundred percent definitive, some might find it worth a try. Honey is known to contain anti-bacterial properties after all thanks to naturally occurring levels of hydrogen peroxide – another common ulcer remedy.



There have been claims that increasing intake of vitamin C and B can shorten the recovery time of mouth ulcers, among other benefits. However, no body of research has actually proven its effectiveness in doing so. As a result, your mileage may vary.


Mouth ulcers are largely unpleasant and can sour even the sunniest of moods. Though small, these ulcers can be extremely irritating and painful. The next time you get one, consider going through some of these remedies and find out which one works best for you!
