Fixed metal or ceramic brackets and wires that move teeth into alignment, adjusted every four to eight weeks. Treatment commonly takes 18 to 30 months.
A routine visit covering an examination of teeth, gums and existing dental work, with scaling and polishing to remove plaque and tartar. Recommended every six months.
Repairs teeth damaged by decay, chips or wear: the damaged portion is removed and the tooth is rebuilt with tooth-coloured filling material, usually in a single visit.
Straightens teeth with a series of removable clear aligners changed every one to two weeks. Treatment commonly takes 6 to 18 months depending on case complexity.
Custom appliances worn after braces or aligner treatment to hold teeth in their corrected positions — removable clear or Hawley retainers, or a fixed wire behind the teeth.
Lightens the shade of natural teeth using dental-grade whitening gel, applied in-clinic or with custom take-home trays. Results vary with the cause of discolouration.
