Dear Mr Patel, I have six porcelein veneers fitted four on top centre and two lower centre. When whitening with home kit could this potentially loosen my porcelein veneers. The reason I ask it may be purely co-incidental but recently I have had two of them fall out within a month of each other they were fitted in 2000. I am considering having crowns fitted the next time one of my veneers breaks or falls out would it be a more benefical way in the long term I was advised if I keep getting my veneers replaced my original tooth with shorten and I may eventually end up with not having enough tooth for the veneer to stick onto. I would very much appreciate your thoughts on both my concerns. Kindest regards,
