Modern dentures very closely approximate real teeth and it’s likely that most people won’t know you are wearing them. There’s no hard-and-fast rule on when or if you should tell someone you are wearing dentures, though you may feel the need to if you are invited for dinner where you won’t have control over what you are served, or if you begin dating. Dentures don’t need to be a dark secret, but remember that if someone disrespects you after learning you wear dentures, they may not be the friend you thought they were.
