Self Analysis

Although most people can whiten their teeth, not everyone is a good
candidate. Teeth whitening only whitens natural tooth structure.
Any fillings, crowns, veneers or restorations(including dentures) will
not whiten.
Stand in front of a mirror and evaluate your smile. Give specific
attention to any discolourations and existing dental work on your front
top and bottom teeth.

1. Old stained front fillings?
If whiter teeth is your end goal then you would possibly want
to replace old stained front fillings or yellow crowns anyway to
match your new whiter smile. Whiten your teeth first then replace these unsightly restorations.

2. Tray Whitening
Whitening Direct supports tray whitening that gradually whitens your teeth 1 day at a time. This is great as it puts you in control of how white you want to go.

4. See your Oral Hygienist
For best whitening results all the surfaces of your teeth must be clean from plaque or tartar. If you haven't seen your hygienist for a while, get your teeth cleaned first for optimum results.

5. People with white spots on their teeth
Initually these white spots will whiten more and give an uneven level of whitening. With continual whitening the remainder of the tooth will 'catch-up' creating a more 'even' level of whiteness.

6. Old restorations
If you have defective or loose teeth, crowns, veneers, gum disease or tooth decay it is best to consult your dentist about
these before considering tray whitening. The 'suction' created by taking impressions is minimal, but might loosen these restorations.

7. A Discoloured front tooth
A discoloured front tooth often is the result of trauma to the nerve or previous root treatment. A special whitening treatment (walking bleach) is recommended from the dentist that whitens the tooth from the inside out.


8. People who should not whiten their teeth unless indicated by their dentist

	Pregnant or Lactating women As with most medicines or treatments it is best to leave teeth whitening until a later stage.
	Children under the age of 12 years
	If you have dental restorations (crowns, fillings, veneers, dentures etc.) on your front teeth and do not want to replace these with a whiter shade after your whitening. (Please note : The gradual whitening effect put you in control of the level of whiteness, so you can stop whenever you are happy with the result)
	People with a high GAG reflex Taking impressions mean to be able to tolerate putting the impression trays in the mouth
	People with very sensitive teeth Teeth whitening causes temporary tooth sensitivity to some people's teeth. This is a normal and temporary response. You might want to get a desentising gel from your dentist. Alternating between whitening days also works well.
