Can teeth be resistant to whitening?

These types of stains can be the result of fracture, antibiotics, routine wear and tear, or aging, or excessive intake of systemic fluoride during dental development. A recent survey showed that 80% of Americans ages 18 to 49 want whiter teeth, and women lead in this area with 85%. And 6 out of 10 people believe that a whiter, brighter smile would increase their self-confidence, especially in the 18-24 age range. Traditional whitening treatments don't work on porcelain or most cosmetic adhesive materials.

Teeth whitening will NOT alter the natural color of the tooth, however, it will remove all stains and restore the natural color of the tooth when used correctly. Teeth whitening is best done under the care of a dental team. Not all patients will benefit from whitening or are suitable candidates for the procedure and it is recommended that the patient undergo a clinical evaluation to understand why teeth are discolored. The causes of discolored teeth range from extrinsic sources (related to external causes, enamel stains) to intrinsic sources (dentin stains).

Determining the cause is critical because the type of discoloration will determine if teeth whitening is the right treatment. For some patients, tooth discoloration may be a sign of a disease or condition that requires dental treatment, 2 Professional whitening (life whitening) focuses on enamel staining (extrinsic staining), which cannot be removed during full mechanical scraping and polishing, 4 Some extrinsic stains can be very resistant to teeth whitening. Are you considering teeth whitening treatments to eliminate discoloration from your teeth? Do you also have restorations such as fillings, veneers, or dental crowns in your mouth? Teeth whitening procedures are not effective on dental restorations because they are stain resistant anyway. Even your teeth whitening dentist will warn you about this dilemma, especially if you intend to get veneers or crowns after improving the appearance of your teeth.

Laboratory-based research suggests that in-chair whitening performed by dentists increases enamel strength and makes it more resistant to acid erosion. In contrast, whitening at home was shown to increase the loss of mineral content within the enamel, which over time can lead to weakness. Products that don't actually contain or release hydrogen peroxide are unlikely to be very effective at whitening teeth. In modern Australia, teeth whitening is offered by dentists, other dentists and cosmetics companies on the high street.

Once teeth have been whitened, there is no need to continue whitening them, but the effects will gradually fade over time. In addition to the health aspect, teeth whitening solutions can create discomfort or even pain when they come into contact with decayed parts of a tooth. The only way to completely remove all stains is to do it in the office or use custom teeth whitening trays with a whitening agent based on carbamide peroxide or hydrogen peroxide. According to the FDA, the term “whitening” is allowed to be used only when teeth can be whitened beyond their natural color.

Young patients, such as adolescents or young adults, are more susceptible to the commercialization of teeth whitening. If you are planning veneers on your front teeth, the placements will act on their own to give you brighter visible teeth when you smile, but the installations are customized according to the natural color of your teeth. Virtually everyone who opts for a teeth whitening solution sees a moderate to substantial improvement in the brightness and whiteness of their smile. However, if you undergo teeth whitening treatments before having restorations, you will likely show two different colors in your mouth that won't look pleasant.

The cost of teeth whitening can vary significantly from product to product, procedure to procedure. When your gums are red, swollen and bleed, teeth whitening treatment can be very uncomfortable due to irritating your less-than-healthy gums. The same analogy to house paint also works here, undergoing any teeth whitening treatment while there is visible plaque is a 26% waste of money; you just won't get the best results and it's not healthy. Clinical decisions regarding teeth whitening are based on patients' wishes to whiten their teeth, a history of allergies (especially with regard to whitening materials), and information on tooth sensitivity.
