Re: Worn fillings and braces
I had to wear braces and orthodontic appliances for quite a few years and I've never had a cavity. Not everyone who wears braces, even for an extended period of time, has decay issues when the braces are removed.
Fillings will naturally wear, especially on the occlusal (biting) surface of your teeth. It's not uncommon for them to feel worn. If you do not have any sensitivity in the teeth and/or there are no rough edges or anything that feels like the filling may have cracked, then the fillings are most likely ok and do not need replaced.
