We all know how annoying mouth ulcers can be. Also known as canker sores, they are painful sores that appear on the tongue, gums, roof of the mouth, or inside the lips or cheeks. When you have a mouth ulcer, the nerve endings just below the surface become exposed. These nerve endings then become very sensitive to food, drink, air, and saliva, which can all cause extra pain and slow down the healing process. This is why ulcers can stop you from being able to concentrate, eat, drink, and even speak as normal. The good news is that we have a remedy: GUM Afta Clear® Rinse. This mouthwash acts as a barrier to protect the wound, promoting healing and providing pain relief, so you can get back to normal life as quickly as possible.
