The dentist clarifies the main doubts about products that promise to whiten teeth
The research of teeth whitening has grown a lot in recent years and, with that, the appearance of miracle products that promise to whiten teeth. According to Bruna Conde, a dentist and oral health specialist, these products called whiteners can soften stains, but not eliminate them, as they act superficially.
Why don’t whitening products work?
The color of the tooth, in its entirety, is called intrinsic (color that occurs naturally inside the tooth). That is, it can only be altered by substances that penetrate the tooth, releasing oxygen to decompose large pigment molecules. These materials are acids and whitening gels based on hydrogen peroxide and carbamide peroxide, administered in the clinic and appropriately indicated by specialized dentists.
The compositions can affect the teeth
The specialist points out that the whitening agent if used improperly can cause dental sensitivity, damages the gum and helps in gingival retraction. Teeth can also discolor from each other and can completely lose protection and tooth enamel. To avoid these problems, dentist Bruna Conde clarifies the myths and truths about teeth whitening. Watch!
1. Activated carbon pastes as a whitening agent?
Myth. In addition to not containing the ingredients necessary to fight tooth decay, they are extremely abrasive. This can cause tooth enamel wear, gum shrinkage, and tooth sensitivity. And, for those who have tooth restorations, charcoal products can stain and cause dark pigmentation.
Two. Can coal dust remove tooth enamel?
Truth. There is no scientific evidence or protocols to guide the use of these products. The risks associated with the application are high, as the whitening sensation it causes comes from the removal of part of the skin tooth enamel. This is because it is abrasive and corrosive, causing great wear.
3. Does baking soda help whiten teeth?
Myth. According to dentist Bruna Conde, baking soda only works by removing surface stains from teeth. “Bicarbonate is a highly abrasive substance and can help remove surface stains from teeth, which cause the impression of whitening. However, the product can damage teeth by removing natural protection, causing extreme sensitivity and tooth wear,” he warns. the professional.
4. Should bleaching only be performed if the tooth is healthy?
Truth. Bruna Conde points out that before dealing with aesthetics it is important to pay attention to the health of the teeth. “You can only whiten inside healthy gums. No accumulation of tartar / dental tartar, bacterial plaque, cavities and deficient restorations. Take care of your health first and then think about aesthetics. Also because the tooth does not whiten if it is not healthy “, emphasizes the dentist.
5. Isn’t it advisable to do whitening without first consulting a specialist?
Truth. If you already have some wear on your teeth and in the region near the gum, the risks are even greater. In general, these products are not the solution for those looking for a perfect smile. “A person worried about yellow spots or teeth should consult a specialized dentist who is able to concretely and safely solve this problem,” concludes the dental surgeon.
