Mouth sores. Then what to do?

If the mouth sores are not recurrent, you can wait for approximately a week for them to subside. Any ulcer in the mouth usually Hills in 7 to 10 days unless it has any other secondary factor associated with it. You can use anaesthetic ointments like dologel CT for temporary symptomatic relief till that duration. And whether you have mouth ulcer or not, a very honest and firm suggestion will be to stop using a tongue cleaner whether it is made of plastic or wood or metal. Tongue cleaners do not clean the tongue efficiently and rather cause more harm than good. The best way to clean your tongue without any damage is to use your toothbrush only to clean your tongue after every time you brush your teeth. Regards.
