G Force Teeth The problem here is that there is not a strong enough concentration of any chemical, and it is not concentrated on your teeth long enough to make ANY noticeable difference to the whiteness of your teeth. The only real "whiteness" if you can call it that, which is created by toothpaste is actually the abrasive action of the toothbrush or paste against your tooth enamel. This scratching DOES wear down tooth enamel and also removes large chunks of staining material on the tooth surface, but not the tiny staining particles which make teeth look more yellow. This is the same thing with "Tooth Polishes" which only act like a fine sandpaper to remove tooth enamel while brushing and will cause increased tooth sensitivity with prolonged use tooth enamel thins.

As with the Risk vs Reward argument, while there is significant damage caused to tooth enamel from tooth brushing over time, on balance this is better than the consequences of not cleaning your teeth.

Don't be fooled by those expensive "whitening toothpastes" - they do not make a noticeable difference to the whiteness of your teeth, they are abrasively removing enamel from your teeth and you're better off spending your money on something that does work.

Who is suitable for Teeth Whitening?

The generally recommended rules to define people who are suitable for teeth whitening are:

Over 16 years of age (due to potential development of the teeth prior to this age, parental consent may be required)

Not Pregnant or Lactating (this is an additional safety measure to protect babies, although you would not generally be able to swallow enough Hydrogen Peroxide from a normal teeth whitening treatment to harm your baby)

No known allergies to Hydrogen Peroxide. If you have ever developed skin irritation when bleaching your hair with Hydrogen Peroxide, you may be allergic. But if you don't know you're allergic, it will become evident in the first few minutes of a teeth whitening treatment, and you can simply stop the treatment. Any side effects, no matter how discomforting will disappear in a few days with no permanent damage.

Aside from these conditions, teeth whitening is not advisable for people with Dental Braces, people with gum disease, open cavities, leaking fillings, recent oral surgery, or other dental conditions. If in doubt, I recommend you visit your Dentist prior to using a professional strength teeth whitening product.

People with grey or blue tint colour to their natural teeth may also not benefit as greatly from teeth whitening using Hydrogen Peroxide, as people with yellow or brown tint colour.

If you have Gingivitis or Periodontal disease, any Hydrogen Peroxide bleach on your gum line will be painful and may produce a small amount of bleeding at the gum line. As a result, I don't recommend whitening your teeth until these issues are under control with your Dentist. What is interesting however, is that reports have shown that Hydrogen Peroxide can kill the bacteria which causes Gingivitis, possibly preventing further damage.

What are the Risks with Teeth Whitening?

Whitening treatments are generally safe, however, some of the potential complications of these treatments include:

GUM IRRITATION: Whitening gel that comes in contact with gum tissue during the treatment may cause inflammation and/or blanching or whitening of the gums, gum line or inside lips. This is due to inadvertent exposure of small areas of those tissues to the whitening gel. The inflammation and/or whitening of gums is transient, meaning it does not last, and any colour change of the gum tissue will reverse within two hours, usually within 10-30 minutes. Persons with a history of mouth ulcers may develop temporary mouth ulcers which usually disappear within a few days after treatment.

TOOTH SENSITIVITY: Although more common with the in-Office Dentist Treatments using very strong bleaching gels, some people can experience some tooth sensitivity for a period after the whitening treatment. People with existing sensitivity, recently cracked teeth, micro-cracks, open cavities, leaking fillings, or other dental conditions that cause sensitivity may find that those conditions increase or prolong tooth sensitivity after a cosmetic teeth whitening treatment.
