Q. Hi. My wife has returned from Poland after some dental work. We always wanted to have a holiday there and she needed 4 veneers replacing so we combined the two. We had a fab time and the Polish dentist could not have been more proffessional. There is a small issue however with her 2 front teeth, and whilst the dentist gave a 2 year gaurantee, and has said he will happily replace them free of charge, im reluctant to continue as more flights, hotel bills, and holidays are involved, and if there was a further problem it would get too expensive, hence having the work done here. Anyway, the 4 teeth at the front were to have replacement veneers done, but on inspection the dentist suggested having the front 2 made into crowns as the teeth protruded. This was done and my wife is over the moon with her flatter 2 front teeth and now rounded top set of teeth, and the 2 teeth either side having the veneers replaced. After returning we have noticed in some light that the 2 front teeth have a sort of dark shade on them ? and, one of them looks like you can see very faintly the yellowish tooth underneath ? Is this possible with crowns ? do you see the tooth underneath sometimes ? what is the dark area that is apparent under certain light ? she is not 100% happy and i think they will need replacing, unfortunately adding to the cost. How much are UK crowns ? and is it possible to match them up to the 2 new veneers ? (1 each side)
