Myths of teeth whitening

Tooth whitening is an aesthetic treatment in which, through different techniques and procedures, the original color of the teeth is restored. If you are thinking about rekindling your smile, but have some doubts, check out the 9 most common myths of teeth whitening and the recommendations of experts.   1. WHITENINGS DAMAGE DENTAL ENAMEL Regarding the damages that your teeth can suffer in the process of any dental treatment, everything depends on the way the procedure is performed and who does it. “There are very strong, very aggressive peroxides that combined with the laser do demineralize the tooth and can damage it. That's why I don't do that kind of treatment, ”says dentist Raúl Benavides, an expert in dental aesthetics. The dentist Roberto Carillo also agrees that the biggest myth about teeth whitening is that it damages tooth enamel. "The objective is to bring the active ingredient to the tooth segments where the chromatic particles are discolored, so a procedure supervised by a professional dentist does not damage the dental structures," says Carrillo.   2. HOME WHITENINGS DO NOT WORK There are different types of teeth whitening, some of them are homemade, that is, they can be applied at home after seeing a specialist, but there are also homemade pharmacy products that promise to whiten teeth. “Pharmacy treatments can help you maintain color after professional whitening. They will never bleach you like a professional made by a dentist, but once the dentist's bleaching is finished they are good products to maintain color, ”says Benavides.   3. WHITENING DENTAL PASTS WORK Toothpastes that claim to whiten your teeth can serve as support after professional whitening, but do not whiten your teeth in a really very noticeable way.   “Toothpastes that promise to whiten your teeth bring a very low peroxide level of 1 to 2 percent. We battle to bleach with 10 percent. We use a peroxide between 16 and 22 percent, then a paste with 1 percent because it will disappoint you and will not meet your expectations, ”explains Benavides.   4. WHITENING LEAVES SENSITIVE TEETH One of the most common myths is that it is said that teeth whitening leaves your teeth very sensitive. “It depends on how they do it to you. The one that hurts is the laser, which I do not recommend, ”says Benavides. Carrillo points out that although sensitivity in the teeth is common in treatment, precautions should be taken to prevent it from becoming a prolonged discomfort. "Although hypersensitivity (or tooth sensitivity) is the most common side effect related to teeth whitening, this is usually transient, disappearing without a trace shortly after the end of treatment."   5. THE WHITE SODIUM BICARBONATE YOUR TEETH It is common to share homemade beauty tips that normally include sodium bicarbonate as an ally against stains on teeth. However, if care is not taken with its use, it may end up being harmful to the denture.
