Although the “folio white” teeth that some celebrities wear is indeed unnatural (teeth are never that color!), It is also true that we would all like to preserve their original tone for longer.
Teeth whitening is “in.” But they are not suitable for everyone, and we must be cautious with them because they can harm our oral health.
We should be more concerned with your health than your color
In addition, we must know where “the limit” is and the dangers of trying to whiten our teeth excessively.
SOMETIMES THE SOLUTION IS SIMPLE
If you have noticed that your teeth have darkened, you can try to regain their natural tone, but keep in mind that sometimes it is not necessary to resort to aggressive treatments:
- External stains can be due to certain bacteria (chromogens), food pigments (such as tannins), chlorhexidine from mouthwashes, or tobacco. They are removed with a dental cleaning and regular brushing after each meal. They are not a real problem if hygienic habits are maintained.
In this case, you can resort to professional whitening treatments or white porcelain veneers (sheets that the dentist sticks on the tooth).
BLEACHING DOES NOT WORK FOR EVERYONE
If you resort to whitening, you must consider when they are not suitable or what their “limits” are.
- Do you suffer from tooth sensitivity? Whitening products are not recommended in this case, as they can increase discomfort and worsen the situation.
- When there is some other oral pathology, it is contraindicated in periodontal disease, cavities, or tooth fracture, for example. “It must be taken into account that the bleaching agents that release oxygen to destroy pigments are aggressive,” warns Dr. Joshipra.
- Suppose you have a filling in a front tooth. The treatment does not act on specific materials, and you can tell the difference.
MAY CARRY SOME RISKS
A dentist should always supervise professional whitening treatments, and the reason is apparent: they can cause damage.
- They can affect the gums and teeth. Isn’t it true that it leaves our skin white when we touch hydrogen peroxide and can even itch? Well, imagine that in a gum! It can burn it or irreversibly damage the teeth. Therefore, it is essential to go to a trusted specialist.
Sometimes it is painful. “Depending on the porosity of the enamel, if the product touches the nerve, the experience can be very painful.” Dr. Joshipura.
WATCH OUT WITH HOUSEHOLD BLEACHES
Some products promise to lighten your teeth up to 8 shades. Be suspicious. Dentists say it is impossible!
- How do they work? What some “whitening” toothpaste do primarily is “polish” with abrasive substances. They can be used to remove surface stains. Others temporarily stain the tooth with purple particles that bind to the enamel and counteract the yellowing of the dentin, creating an optical illusion.
- They have limited whitening power. Household whitening products contain hydrogen peroxide or carbamide. Both give off oxygen, which is what destroys pigments. But since oxygen is very labile, it evaporates or mixes with the atmosphere in toothpaste.
- Keep an eye on the product you choose. The legislation allows cosmetic dentifrice products with up to 0.1% hydrogen peroxide or carbamide peroxide to be sold in the pharmacy (and only to those over 18 years of age). Higher concentrations are not safe.
- Whitening treatments are often prescribed to finish treatment in the clinic but should always be used under medical supervision.
