Am I a Candidate for Tooth Whitening?


Almost anyone with natural permanent teeth can qualify for tooth whitening. Your dentist will be able to assess your oral health and recommend the whitening method that is best for you. Depending on the type and severity of the staining or discolouration, he or she may suggest one or more of the following treatments:

  • A professional cleaning to remove external staining caused by food and tobacco
  • Use of a whitening toothpaste to help remove surface stains between dental visits
  • Bleaching, in-office or at-home, for more stubborn discolouration
  • Porcelain veneers or tooth-coloured restorations to fix irregular or damaged teeth or to achieve specific results.

Ask your dentist which method will achieve the best results for you.

  • Teeth that are yellow respond best to bleaching. Brown or grey teeth, or teeth striped or mottled from tetracycline or too much fluoride, may not whiten evenly when bleached.
  • People with periodontal disease or particularly sensitive teeth may want to avoid chemical whitening techniques that can irritate tender gums and teeth.
  • Bleaching works on natural teeth and is not recommended if you have tooth-coloured fillings, crowns, veneers or bonded restorations in your front teeth.
  • In some cases if appropriate, a crown or veneer may result in a whiter and more appealing smile.

Brightening your smile is as easy as visiting your dental practitioner for a whitening treatment or purchasing one of the many at-home treatment options available. You do not necessarily have to change your habits to whiten your teeth. Simply replacing your regular toothpaste with whitening toothpaste is a great way to start whitening your smile gradually. Using a whitening mouthwash, whitening pens, strips or trays are all ways to supplement your normal oral hygiene habits.

Certain foods and beverages can cause teeth to become discoloured. These include coffee, tea, wine and sports drinks. Smoking also causes teeth to become discoloured.


While our teeth are not, by nature, perfectly white, most people feel that they could improve their smile with brighter, whiter teeth. Over time, teeth acquire surface stains as a result of eating and drinking certain foods and beverages. They also naturally discolour with age, as a result of acquiring pigmentation inside the teeth. There are various ways to safely remove the surface stains and the internal discolouration, leaving a whiter, more radiant smile.
