We speak with Christopher, 44, has no teeth and is unable to wear dentures due to having a strong gag reflex. Shanell who is a single mum of three who has chronic dental phobia, and Pete who struggled with heroin and then meth addiction from age 15- 54, nearly 40 years. He says his teeth were ok until his thirties but then he went on the methadone program for years and his teeth really suffered.
