What is teeth whitening?
Teeth whitening is an aesthetic procedure that aims to make teeth whiter by removing pigmentation and stains acquired over time. These stains can be caused by foods, drinks such as coffee and wine, cigarettes and even the natural aging of tooth enamel.
The whitening process acts chemically on the pigments, breaking down their molecules and giving the appearance of whiter teeth. It is important to understand that whitening does not mean making your teeth completely white, but rather returning them to a lighter, healthier shade.
How does it work?
Teeth whitening is done in two general ways: in the office or at home, under professional supervision. In the office, dentists use bleaching agents based on hydrogen peroxide or carbamide in high concentrations, usually activated by special lights, such as lasers.
In the supervised home method, the patient receives customized trays and a lower concentration whitening gel to use at home, as per dental instructions. In both cases, the whitening agent penetrates the enamel and dentin of the teeth, breaking down the pigment molecules that cause the yellow or dark coloration.
It is important to emphasize that the success of teeth whitening depends on the technique used, the concentration of the chemical agent and the initial condition of the patient's teeth.
Types of teeth whitening
There are different methods of teeth whitening, and each one meets specific needs:
Laser whitening
Performed in the office, laser whitening is fast and efficient. The whitening gel is applied to the teeth and activated with laser light, intensifying the results in just a few sessions.
Supervised home whitening
In this method, the patient uses custom-made trays to apply the whitening gel at home, usually for a few hours a day or overnight. Monitoring by the dentist is essential to ensure safety and effectiveness.
In-office whitening without laser
Without the use of special lights, the dentist applies whitening products directly to the teeth in periodic sessions. This is an option for those who prefer to avoid lasers or have contraindications to the use of intense light.
Benefits of teeth whitening
Teeth whitening can bring several advantages:
- Improved aesthetics: Brighter, more beautiful teeth contribute to a younger, healthier appearance.
- Increased self-esteem: A whiter smile has a positive impact on self-confidence.
- Social and professional benefits: An attractive smile can facilitate social interactions and make a good impression in the workplace.
Additionally, the procedure can encourage even stricter oral hygiene habits.
Limitations and risks of the procedure
Despite the benefits, teeth whitening also has some limitations and risks:
- Tooth sensitivity: Temporary sensitivity to hot or cold foods is common after treatment.
- Variable results: Whitening may not be effective for all types of stains, especially those caused by medications such as tetracycline and other antibiotics. In these cases, the treatment for whitening teeth is different. Read more.
