I'm having a nightmare with my veneers.
I have 4 veneers on my front teeth, 1 of which has fallen off 3 times in the past 10 years.
Problem is the backs of my teeth have gone very discoloured and enamel worn away.
I'm fed up with them and it's really getting me down.
I brush 3 times a day and my other teeth aren't like this.
What happened and what can I do to fix?
