a. What is the difference between cleaning and whitening?
Cleaning is a routine procedure that removes superficial dirt and debris from the tooth surface and gums. No Chemicals substances are usually involved unless specific medications are used to improve healing. Whitening is a cosmetic procedure to improve the shade of the teeth and it removes pigments and stains from the uppermost layer of the tooth or enamel to give whiter teeth. It does not involve cleaning the gums.
b. Does it hurt to get whitening done?
It might lead to a limited period of sensitivity because of the ingredient used to whiten teeth, but this subsides eventually. Most people do not experience any sensitivity issues unless already present.
c. How long does it last?
Whitening can last for up to two years or more. This depends on a person's habits, maintenance etc.
d. How is it done?
The doctor thoroughly cleans all the teeth. The ingredient is then applied on each tooth and activated using light. Every session lasts up to 45 minutes. Sessions can be repeated depending on the results required.
