Blanqueamiento de los dientes - Tooth whitening

The smile is a vital part of facial beauty, and so for us it is important that you can show teeth which are as esthetically attractive as possible and one of the most important esthetic characteristics is their color. Nowadays, we can achieve our ideal color through the simple treatment of Tooth whitening.

It is important to differentiate between two concepts when we talk about cleaning your teeth, the concept of washing or brushing as opposed to whitening. When a tooth is discolored by extrinsic stains (tobacco, foodstuffs, etc.), normally brushing and rinsing will remove the stain and restore the original color. However when a tooth is affected by what are classified as intrinsic discolorations (medicines, changes in the formation of the enamel or dentine, aging, etc.), can only be treated with a whitening procedure, always supposing that the pathology which is causing it is susceptible to this kind of therapeutic procedure.

Dental whitening is one of the most conservative treatments which allow us to give back to the tooth a color in accordance with the acceptable color standards for natural teeth. It involves a series of minimally invasive procedures, which improve the aspect of the teeth without changing their morphology and facilitate the maintenance of good dental and periodontal health.

They are treatments which must be supervised by a dentist because according to the type of discoloration in the patient, the professional will establish a protocol to follow with regard to time, number of sessions, etc. after taking into account the oral and periodontal state of the patient.

Nowadays carbamide peroxide (between 10%-22%) or hydrogen peroxide (between 20%-40%) are used. Dental whitening lasts for approximately 2-3 years on average, further whitening procedures being necessary in order to maintain the color.

In order to establish the ideal therapeutic attitude with respect to the whitening, the causes that produce the discoloration must be identified. Depending on the cause of the discoloration and the previous treatments the tooth has undergone either internal or external whitening is carried out.
