Teeth Whitening

Cosmetic Teeth Whitening at Cambridge Dentistry

Tooth whitening is a cosmetic non-invasive dentistry procedure that can be a very effective way of lightening the natural color of your teeth without removing any of the tooth surface. Yellow or stained teeth are a common problem most people can develop at some point in their lives.

Causes of Tooth Staining

Food and diet are the most common culprits of teeth discoloration, along with:

  • Medicine – Tooth darkening can be a side effect of certain antihistamines and high blood pressure medications. Young children who are exposed to antibiotics when their teeth are forming may have discoloration of their adult teeth later in life.
  • Excessive fluoride – Fluoride in large amounts can cause white spots to appear on your teeth.
  • Genetics and aging – The enamel of your teeth wears thin as you grow older, allowing the natural yellow or brown color of the underlying dentin layer to show through. Also, genetics can play a role as some people naturally have brighter or thicker enamel than others. Damage to the teeth which produce sizable cracks in the teeth can collect large amounts of stains and debris too.
  • Dark drinks or colorful foods – Coffee, tea, and red wine are well known for their tooth staining capabilities, other dark liquids such as fruit juice, soda, and even beer can make your smile less bright. Heavily pigmented foods like cherries, blueberries, and soy sauce can quickly stain teeth.
  • Tobacco use – The two chemicals found in tobacco create stubborn stains. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen, then it turns into a yellowish, surface-staining substance.
  • Bad oral hygiene – If stain-producing substances are not being routinely removed from your teeth it will allow bacteria to build up. The more you brush and floss properly and have your teeth professionally cleaned, the better chance you have to fight off the stains that can result from bad habits.

If you feel like your smile is lacking some sparkle or your teeth are more yellow than they used to be, there can be help for you right in our dentist’s office. Whitening will not work on all teeth, so it’s important to talk to our dentist before deciding on the procedure.

For example, yellow teeth will probably bleach well, brown teeth may not respond as well, and teeth with gray tones may not bleach at all. Whitening will not work on caps, veneers, crowns, or fillings. The effects of whitening are not permanent, and you may need a touch-up which will vary from person to person depending on your use of staining foods and drinks.

How Does Teeth Whitening (bleaching) Work?

Our dentist can provide you with a custom-made tray for at-home whitening.

Two visits to our dentist – on your first visit, impressions (molds) of your teeth will be made. At your second appointment, the new trays will be fitted and adjusted to your teeth.

You will be given instructions on how to place the whitening solution in the tray and for what length of time.

This convenient and comfortable whitening procedure can be done in your own home at a slower pace and can take anywhere from a few days to a few weeks, depending on your individual needs.

Some people may experience tooth sensitivity. In most cases, the sensitivity is temporary and will diminish after you have stopped the procedure.

To help you get a sparkling white smile, call Cambridge Dentistry today for an appointment. We have two convenient locations to serve you. Dundas and Franklin Plaza (519) 622-3199 or Westgate Plaza (519) 623-2400
