If your gums are sore and swollen, use a mouthwash of medium hot water with a teaspoonful of salt. (Check that it is not too hot before using it.) Swish the salt water around the tooth, trying to get into the areas your toothbrush cannot reach. An antibacterial mouthwash such as Corsodyl can also reduce the inflammation. Pain-relieving tablets such as paracetamol or ibuprofen can also be useful in the short term, but see your dentist if the pain continues. Difficult wisdom teeth are normally managed by specialists in oral surgery.
