The types of teeth whitening
Homemade tooth whitening: The homemade tooth whitening technique, performed outside the dental office and monitored by the dentist, is the most common and safe. Besides, it is also the one that brings better lighting results. It is suitable for all types of whitening needs. Its contraindication, however, is individuals with gingival diseases and extensive gingival retractions – the only disadvantages of this technique. It is always the first choice when aesthetic urgency does not count for much in the treatment.
In-office tooth whitening (conventional): The most common technique among those applied by the dentist in the dental office does not use light sources (LED, LASER, or halogen sources). And unlike home tooth whitening, whose treatment lasts between 7 to 21 days, the outpatient technique can deliver excellent results even in a single consultation – of 4 maximum possible sessions. But it has disadvantages: it is less secure to the teeth and can still leave the area close to the yellowed gums. It is indicated for aesthetic emergencies or individuals with extensive gingival retractions.
Laser tooth whitening: The most glamorous – and rare – a technique for tooth whitening can frustrate many individuals for the results. It is that, according to dental research, the effects of laser tooth whitening are similar to conventional techniques – and even inferior to the homemade technique, with trays. The indications follow the same for the other techniques applied in the office. The highest risks for pulp inflammation, however, must be taken into account when selecting the best technique.
Tips for the correct teeth whitening
During treatment, it is also vital that the patient avoid the consumption of highly pigmented foods, as, during the use of whitening gels, the teeth become more porous. Therefore, there are risks of the appearance of stains.
Meals and beverages such as coffee, açaí, soft drinks, hot sauces, and processed products should be avoided during the treatment period.
The cigarette must be suspended. Otherwise, the results will not be satisfactory.
Avoid the consumption of alcoholic beverages and very acidic foods.
Oral hygiene should always be done after meals, and floss should be used daily.
Use colorless toothpaste and, if using rinses, they should be white, as colored products hinder the whitening result.
