I dipped for about 5 years and just quit when I kept getting a white sore or patch of skin under a tooth on the gums.The one tooth you can see the root it's receded to the bottom and I keep getting a painfull white patch of skin or bump on the gum below the tooth that has receded to the root....I've been told I might have to get gum graphed there,but my main concern is mouth or gum cancer what do you think?
