What is teeth whitening? How does it work?

A teeth whitening procedure is a non-invasive treatment of bleaching your teeth.  You can notice a substantial improvement in the brightness and whiteness of your smile. 

Reasons for teeth whitening

It is recommended for the following conditions:

  • Normal wearing away of the enamel layer, as seen during aging, exposes the dentin with a yellowish hue
  • Tooth staining due to smoking and tobacco use
  • Discoloration as a side effect of certain medications like tetracycline, antibiotics, or antihistamines
  • Fluorosis (exposure to high levels of fluorides causing white spots on the tooth surface
  • Stains due to certain foods (berries and cherries) and drinks (tea, coffee)

What are the types of teeth whitening?

Teeth whitening systems are of two types:

In-office teeth whitening system

  • Performed at the dental clinic under the guidance of a dentist
  • A high concentration of bleaching agent (active agent) is used to bleach the teeth
  • The active agent is applied on the tooth surfaces and cured using LED or UV light
  • The process takes around 30 to 45 minutes 

At-home teeth whitening system

  • This type of teeth whitening involves bleaching the teeth through whitening trays
  • These are clear plastic customized trays that are fabricated according to your oral impressions 
  • The bleaching agent is filled into the trays and should be worn on top of the arch
  • The clear trays provided by the dentist should be worn for 30 minutes twice daily or overnight 

What does a teeth whitening procedure involve?

The procedure for using the at-home teeth whitening trays is as follows:

  • You must first clean your teeth and gums thoroughly
  • Only a small amount of the active gel should be inserted into the tray
  • Then, you must firmly push the tray into place against the teeth 
  • Do not swallow any excess gel and immediately spit it out
  • Wear the tray for the instructed period of time
  • After the time limit, remove the trays and immediately rinse the teeth
  • Use a toothbrush to remove the gel from the tray 
  • Clean and wipe the tray and place it in a tray holder until the next use
  • Store the gel in the refrigerator or a cool place

Always follow the instructions of your dentist, and do not be tempted to use the gel for a longer period of time.
