Yes. Many of the new modern dental procedures allow people to change the shape their teeth for cosmetic reasons and not just because they have problems like decay or broken teeth.
Dental Crowns
Another option is to have Dental Crowns, sometimes also know as Caps. A crown is a tooth shaped object that is partially hollow inside that is cemented in place and encases the tooth. Once treatment is complete it is only the crown that is visible; your tooth is completed covered right up into the gum line.
Dental Veneers
Veneers, either composite resin or porcelain laminates, are another form of Cap. Veneers are wafer thin and custom made shells that cover your tooth – usually only applied to your front visible teeth. Veneers are bonded to your teeth and can be made to alter the shape of your teeth and the look of your smile.
