Heard fillings can increase your risk of oral cancer due to irritation on your tongue. so should i have them all removed? cancer worse than cavities

Nonsense!: Dental fillings do not increase the risk of oral cancer. This is an urban myth. If your fillings were removed, you would be at much higher risk of a shortened life from bad teeth resulting in infection than from oral cancer. Be cautious in searching the web on health issues; stick primarily with professionally run or moderated sites, like those from health departments and academic institutions.

No risk: No risk for cancer from fillings. See oral surgeon or ENT doc if you have any of these symptoms: Persistent mouth sore, persistent mouth pain, a lump or thickening in the cheek, a white/red patch on the gums, tongue, tonsil, or lining of the mouth, a sore throat, hoarseness or feeling that something is caught in the throat that does not go away, difficulty swallowing/chewing.
