Teeth Whitening Risks

Teeth whitening treatments are considered to be safe when procedures are followed as directed. However, there are certain risks associated with whitening that you should be aware of.

Sensitivity

Although rare with our gentle gel, teeth whitening can cause a temporary increase in sensitivity to temperature, pressure and touch.  In extreme cases some individuals may experience spontaneous shooting pains.  Individuals at greatest risk for whitening sensitivity are those with gum recession, significant cracks in their teeth or leakage resulting from faulty restorations.  If this occurs discontinue immediately and rinse.

Whitening sensitivity usually lasts no longer than a day or two, but in some cases may persist a little longer.  We commend toothpaste for sensitive teeth to reduce sensitivity.

Gum Irritation

Clients occasionally experience some degree of gum irritation usually from applying the gel onto the gum tissue.  Such irritation typically lasts from a few minutes after treatment up to several days.  The use of the vitamin e swab is very successful in eliminating gum sensitivity.

Techni-Colour Teeth

Restorations such as bonding, dental crowns or porcelain veneers are ot affected by bleach and therefore maintain their default colour while the surrounding teeth are whitened.  This results in what is frequently called “techni-colour teeth”.  If the default colour of these restorations is lighter than the natural teeth, the whitening treatment can still be used.  We recommend that the clients teeth be colour checked after the first 20 minute session in these cases, as it may be all that is required to match the restorations.

Who Shouldn’t Have Teeth Whitening?

Pregnant or lactating women are advised to avoid teeth whitening.  The potential impact of swallowed bleach on the fetus or baby is not yet known.  We also recommend the treatment for persons over the age of 16.

Individuals with highly sensitive teeth, or those who are in need of dental work should consult their dentist before having a whitening procedure.
