Teeth whitening is a procedure for lightening the teeth by removing discoloration and stains. As a very popular type of cosmetic dentistry, most dentists perform it because they understand how great it can be on improving and transforming your smile and the look of your teeth. However, it is worth noting that the whitening of your teeth should be repeated from time to time in order to maintain a stronger, brighter color.

Why Is It Needed?

  • Hereditary issues – Genetic factors can affect the smoothness and thickness of the enamel thereby allowing the dentine to be visible. Because the color of the dentine is not white, being visible makes the enamel and your teeth look colored.

  • Progressive build up – each day that passes, the enamel begins to develop a thin coating referred to as the pellicle that has the capability of picking stains.

  • Pores – You enamel contains pores which sometimes create a conducive environment for harboring stains.

  • Bad habits – Using tobacco, bad oral hygiene, and drinking dark-colored fluids such as tea, red wine, coffee, and cola are some of the major contributing factors of teeth staining and discoloration.

  • Aging – as one age, the enamel continues to erode thus getting thinner. As a result, the dentine becomes darker giving your teeth a repulsive appearance.

  • Intrinsic stains – These are stains that occur inside a tooth, majorly associated with exposure to high concentrations of fluoride in drinking water and the use of over-the-counter medicines such as tetracycline antibiotics.

Teeth Whitening Procedure

Teeth whitening follows a three-step procedure as follows:

1) Preparation

Upon visiting your dentist, he or she will thoroughly examine your teeth. This is because the presence of any dental problems determines whether teeth whitening is appropriate for you or not. For example, your dentist will first treat dental cavities before deciding to whiten your teeth. The reason behind it is that the whitening gel can penetrate the decayed areas, thus affecting the gums and the roots.

2) Whitening

Your dentist will begin by applying a substance to cover around the gums to protect them from the bleaching gel.

Afterward, the dentist will apply the whitening gel and activate it using a laser light shined on your teeth. Typically, this in-office procedure takes between 30 to 90 minutes and can be completed in 1 to 3 appointments.

In case your teeth are excessively discolored and not possible to completely whiten them during the 3 appointments, your dentist may suggest further bleaching at home for several days.

3) Follow-up

It is important to follow up with your dentist if your gums become sore or white after undertaking teeth whitening.
