Myths and truths about teeth whitening - What you need to know before treatment

Truth: This is one of the most common myths. When whitening is performed by the dentist and with professional products, the tooth enamel is not affected. The materials used are tested and applied under controlled conditions, following safety protocols.

Truth: Results vary from person to person. The natural color of the teeth, age, diet and type of stains influence the final shade. The goal of the treatment is to achieve a brighter and more natural smile, not necessarily an immaculate white.

Truth: Whitening toothpastes mainly remove superficial stains caused by coffee, tea or tobacco. They cannot change the internal color of the tooth like a professional whitening treatment can.

Truth: Some people may experience temporary tenderness after treatment, but this usually goes away within 24-48 hours. The doctor can recommend special products to reduce sensitivity, if necessary.

Truth: No whitening treatment is permanent. The duration of the results depends on the habits of each person. Frequent consumption of coffee, red wine, tea or smoking can speed up the reappearance of spots. With proper oral hygiene and periodic check-ups, the effect can be maintained for a long time.

Truth: Baking soda, activated charcoal, lemon juice or other remedies advertised on the Internet do not provide results comparable to professional treatments and, when used frequently, can damage tooth enamel or increase sensitivity.
