What is tooth whitening?
Tooth whitening can be described as any procedure that whitens the appearance of the teeth. The actual technique used depends on what results the patient requires, the condition of their teeth, the age of the patient, and their lifestyle.
What discolours teeth in the first place?
Many factors are involved, and these can be divided into external and internal factors. External factors are primarily dietary or lifestyle in cause i.e Tea, Coffee, Red Wine, Smoking, Chewing Tobacco. Internal factors are the natural colour of the teeth, which can be affected by an antibiotic called Tetracycline (only if taken before 12 years of age),dead teeth or decay and ageing. Chalky patches (mottling) of the teeth is caused by childhood diseases such as measles, and fluorosis. Discoloured fillings are best thought of as ‘internal’.
Treatment Options (This is a guide ONLY)
External stains: A scale and polish will remove the vast majority of these stains. Good quality (i.e. Sonicare or Braun 3-D Deluxe) toothbrushes will also remove stains. Tetracycline staining: Mild: Leave. Moderate to severe: Porcelain Veneers. Decay: Remove decay and restore with tooth coloured filling. Dead teeth (usually following trauma). A root filling is required, with or without internal bleaching or veneer or a crown. Ageing related discolouration: External Tooth Bleaching (see below) Mottling: Severe: Veneers. Mild to Moderate: Microabrasion. (see below)
External Tooth Bleaching Zoom 2 and take home kits
Patients can also use the take home kits, these use a chemical to break down stains beneath the surface of the tooth. The technique used here involves taking an impression for the construction of close fitting trays into which the patient applies the bleaching gel and then wears the trays. Very successful for ageing related discolouration. The darker the teeth are, the bigger difference the patient notices. If the patient has any fillings on their front teeth, these will have to be replaced after treatment. Usually lasts 2 years. A lifestyle heavy in external staining factors will significantly reduce this length of time.
Microabrasion
Involves removing the surface layers of enamel by a process of etching, micro-fine diamond burs and abrasive polishing. Only the minimum amount of enamel is removed. Occasionally a deep penetration of mottling may require a tooth coloured composite filling for best results.
