Clinical and radiographic evaluation
As with any other procedure, the dentist must carry out an exhaustive clinical and radiographic evaluation to determine the state of health and if it is feasible to perform whitening, we hope that this article on how to perform teeth whitening can help you make a decision.
This is because not everyone is a good candidate for this procedure. Whitening is not capable of altering the color of pre-existing restorations in the mouth. Therefore, it is necessary to ensure that there are no resins, veneers or crowns in any visible area of the smile, as this would produce unfavorable aesthetic results.
After determining that the procedure is feasible, the dentist performs a dental cleaning. In this way, the dental calculus that may exist around the teeth and possible food remains are completely eliminated.
Also, the teeth are polished using a special brush placed in the dentist’s handpiece in combination with prophylactic paste, leaving them ready to receive whitening. This is a very important point when it comes to knowing how teeth whitening is done, if you have any questions contact with us.
Using a color guide where you can see the different shades of the teeth, the tooth color is determined prior to treatment and the desired color is chosen later.
This helps to have an idea about the possible results that will occur, and to give the patient realistic expectations about the color that their teeth will have.
Gingival barrier placement
Before applying the whitening gel, it is essential to place a protective barrier around the teeth.
Whitening agents exert a caustic effect on the gums and various soft tissues of the mouth. Therefore, the dentist places a protective barrier that ensures that the whitening gel does not come into contact with any other tissue than tooth enamel.
This barrier consists of a special gel that is placed on the neck of the teeth following the contour of the gum. Once placed, it is hardened by a powerful LED light.
Applying the whitening gel
Once the gums are protected, the dentist can place the whitening gel directly on the teeth. This gel solution has an active compound that is usually hydrogen or carbamide peroxide, which is responsible for lightening the color of teeth.
The stipulated time that the whitening gel must act for the procedure to be successful is determined by the manufacturer. However, it is usually between 30-90 minutes. On the other hand, sometimes it is necessary to carry out more than one session to achieve the desired tone.
Finally, teeth whitening is a simple procedure that will help you improve the appearance of your teeth. You just have to go to your dentist for an evaluation and make sure that you are a good candidate for this treatment and after a few hours you will be able to notice the results and smile with confidence.
