If you are not comfortable with porcelain veneers, composite veneers or composite bondings, you can choose alternative options to improve the look of your teeth. The alternatives include dental crowns, teeth whitening or orthodontic treatment such as Invisalign or Braces. Dental crowns are tooth-shaped porcelain caps that are fitted over the teeth to improve their appearance. Conventional Orthodontic treatment includes the fitting of braces and the wire, where as short term orthodontic treatment such as Invisalign consist of fitting translucent plastic aligners over the teeth which are regularly changed. Your dentist might suggest teeth whitening treatment if the problem is only stained or discoloured teeth.
