Teeth Whitening

The outer layer of teeth, the enamel, is responsible for the brightness of your smile. Reflection and scattering of light by the enamel create the color of natural teeth. Your genes are responsible for the thickness, brightness, and smoothness of your enamel. 

Over time, teeth start losing their luster, and a thin stain-absorbing coating develops on the tooth surface. These stains and discoloration can be removed using a non-invasive teeth whitening process. A gel rich in oxidizing agents is used to break down stains to render a bright and lustrous smile. 

Teeth whitening is the most popular cosmetic enhancement and should be performed by an experienced dentist. You must have heard about multiple at-home teeth whitening over the counter products that vouch to deliver good whitening results. However, here are a few reasons why you should consider a professional whitening treatment:

  • Professional whitening is performed under the supervision of a dentist, which makes it safer.
  • The whitening gels used are highly concentrated and rich with oxidizing agents. They produce better results.
  • The results are produced quicker and faster.
  • The whitening trays are custom-made to fit your mouth.
  • All the teeth are whitened and not just the social six.

Why do teeth become yellow?

Teeth can become yellow and stained due to any of the following reasons.

  • With age, the tooth enamel becomes porous and easily absorbs stain-causing substances. It slowly withers away to reveal the yellow dentin below. Aging is one of the prime factors that lead to staining and discoloration of teeth.
  • Consuming certain beverages, fruits, and vegetables like coffee, tea, apples, and potatoes cause discoloration of teeth. 
  • Smoking or chewing tobacco accelerates the buildup of plaque and bacteria on the tooth enamel. It leads to staining and discoloration of the tooth surface.
  • Improper and irregular brushing and flossing often leave the teeth yellow and stained.
  • Certain diseases and their treatment stain teeth. Medicines, mouth rinses and drugs stain the enamel and leave it yellow.
  • Exposure to excessive fluoride present naturally in water or kinds of toothpaste causes discoloration.
  • Dental trauma resulting from injuries can disturb the formation of enamel in children whose teeth are still developing. In adults, dental trauma causes discoloration.

How is teeth whitening done?

Professional teeth whitening requires two visits.

First Visit: Dental cleaning, in-office whitening, and digital impressions 

On the first day of your treatment, a dental hygienist will clean your teeth to remove the accumulated tartar. Clean teeth react better to whitening solutions. 

A gingival dam is then used to isolate the teeth for whitening. A whitening gel is applied onto the teeth and left for 30 minutes. A beam of ultraviolet rays is used to activate the gel and release the oxidizing agents. The process may be repeated a few times to obtain optimum results. 

Your dentist will also take impressions of your mouth to custom-fabricate a whitening tray for you.

Second Visit: Custom-made whitening trays

Your dentist will hand over your newly custom-fabricated whitening tray. These whitening trays fit like mouthguards and carry whitening gels in them. Whitening trays are used for touchups and prolonging the result of the in-office treatment.
