I’d like to improve the appearance of my 4 upper front teeth (molars) . One of the side ones has recently been crowned ; its alignment with the other teeth could be improved upon, but one of the centre molars is protruding, therefore it’s quite difficult. The remaining 3 upper front molars are covered in veneers which have to be replaced often due to discolouration of the white fillings. The dentist did suggest that I could crown the remaining 3 front molars. I am unsure whether I want my natural teeth removed despite ongoing discolouration of white fillings/veneers. What are the options ; my teeth are quite grey in colour : A3 I think was the colour of the recent crown.
