Q. I have composite bonding on my front teeth to fill the gap, but this has cracked around one of them at the top. I need this corrected asap as its uncomfortable. I have moved to London but my NHS dentist is in Colchester, Essex. Also the bonding has only lasted a few months, therefore I do not think the dentist did a very good job, as it is supposed to last longer than that and has already been fixed once. Is this easily corrected? Do I need it done quickly as it feels like it will crack off? Is it possible to have the bonding redone safely?,
