Have B-complex tablets 2times a day, you will get cure sooner.. In addition take manathakkali keerai daily till the ulcers disappear.. May be you need to take that tablet and leaves for 3to5days.. With in that period you will get cured..apply butter on ulcers.. It Can reduce pain..

You can apply ghee too. But you will have to bear the pain for 2 days or so, until they reduce

 best and natural medicine is to add manathakkali keerai in ur diet..immediately u will see the result..do see that u include that in ur diet once in a week...and agathi keerai is good for de worming..no need to go to doctor and take medicine ..

There are mouth ulcer gels which you can use as well if the pain is severe... You can check with the doctor.. I used one long time back dont remember the name.. However, as everyone said, manthakkali keerai is the best medicine that i can think of.. As soon as brush, you can munch a few leaves, it has the best effect.. also you can make kootu or poriyal out of it and have it..

Use dentagel ointment.apply it on the pain ful area.it will give numbness for some time so u will get relief.can use any no times per day.my doctor  suggested this for me
