Clinical Cases Tooth Bleaching

Tooth bleaching is one of the most frequent aesthetic treatments, allowing a simple and efficient way to improve the color of darkened, stained, or yellowed teeth.

At the António Carracho Institute, before starting the whitening process, a clinical evaluation is necessary. We check your teeth and gums and select the best whitening technique for each case.


The bleaching protocol starts in the dental office, with a treatment cycle customized to your case - whitening products and LED lights are used to boost and accelerate the tooth whitening process. At the end of the session, a bleaching kit consisting of – trays, bleaching gel, and toothpaste are given to promote the bleaching effect. This kit should be used for 7 to 10 days. Sometimes tooth sensitivity occurs after bleaching. However, this transient situation has no harmful effects on the tooth structure.

In the first 24-48 hours after bleaching, it’s recommended not to ingest substances that cause pigmentation, such as coffee, tea, and wine, not to compromise the results. If the patient is under a maintenance protocol and wishes to whiten their teeth, individualized trays are manufactured to use at home for a period determined by your dentist, to obtain the desired results.

Step by Step

  1. Oral Hygiene: teeth scaling and polishing are carried out to eliminate plaque and pigmentation, allowing the correct application of the bleaching agents.
  2. In-Office Bleaching: a bleaching session is performed with cycles customized to your case - bleaching products and LEDs are used to speed up and boost the tooth whitening process.
  3. Trays and Bleaching Paste: at the end of the session, Bleaching Trays and Toothpaste are delivered to enhance and maintain the bleaching effect.
  4. Follow-up: 7 to 14 days later, a consultation for evaluation and control is carried out. In some instances, it may take 2 to 3 sessions to achieve the desired result.
