Why a Tooth Whitening System?

Tooth whitening systems offer a wide spectrum of alternatives, ranging from low-priced whitening strips on the low end to costly but usually effective expert dental whitening services. There is a good amount of of tooth whitening systems accessible currently. Why do teeth become yellowed? This is due to the fact that people consume caffeine-containing drinks, smoke, get exposed to antibiotics, and just plain age. Teeth whitening is an effective way to reverse this process, and is so successful that 95% of persons undergoing the system do verify some improvement.

Whitening Strip Method

The next simplest tooth whitening approach is the whitening strip system. You place tooth bleaching tape on your front teeth. This tape is flexible, and contains the gel that bleaches the teeth. This is the most comfortable, least costly, and easiest to utilize tooth whitening approach. This explains the popularity of this technique. However, frequently the results aren't as good as those results seen with the tray-based methods or in-office laser tooth whitening systems. Whitening strips can do a nice job of whitening the exterior tooth surfaces, but achieve a poor job of bleaching the teeth divisions and cracks. A dark division between whitened teeth could look like a bad cavity. If you do not employ a tray-based tooth whitening system, you run the possibility of having irregular or spotty possible results.

OTC tooth whitening products ought to in principle provide the identical tooth whitening effect as a visit to a dentist office, yet with a decreased concentration of the peroxide (5% - 10%), and over a longer time period. This is partially true, but omits the reality that dentists employ a laser tooth whitening system as well as bleach, something not available with OTC products.

Three Primary Approaches to Tooth Whitening

Despite the confusing array of dentist and over the counter (OTC) products, there are practically only three (3) approaches to whitening one’s teeth:

• Dental in-office bleaching
• Self-applied night-time bleaching using a tailored tray or a polyethylene strip
• Individual directed whitening using OTC bleaching products

There is nothing intrinsically good or bad about any of these three basic techniques - each procedure can yield decent results. You clearly can’t put a bleaching agent on your teeth without a viable delivery method and presume it to work. The key to the best outcomes in tooth whitening is the whitening agent delivery technique. In all the tooth whitening methods, the tooth bleaching gel is kept in place by a method of delivery. This is definitely critical to keep the gel in contact with the surface of the tooth.

The ADA Seal of Acceptance

The ADA guideline for a whitener requires that it not become harmful to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What a person must know about the ADA seal of acceptance is that no OTC product has as of yet attained this coveted designation. There are differing levels of worth to all these whitening systems. This is an area that the U.S. FDA does not get involved. Nonetheless, the American Dental Association (ADA) does set rules for tooth whitening products. Only particular tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners that have obtained the ADA Seal, the active ingredient is a 10% carbamide peroxide solution.

Tooth Whitening Toothpaste

The most uncomplicated tooth whitening system is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you simply desire some simple maintenance of prior tooth whitening, then this is the way to go. But, if the situation is more deep rooted, then more tooth whitening systems ought to be looked into.

Take Home Tray Whitening

With a take home tooth whitening tray system, which the patient can perform at home, the dentist makes an impression for a model of the patient’s teeth. Later, a perfect fitting bleach tray is fitted from this impression. Finally, a bleaching gel is prescribed by the dentist. At home, the bleaching gel is placed in the bleaching tray by the patient and the tray is consequently worn for one to two hours at home at a convenient time by the tooth whitening patient. Because the bleaching tray is so custom fitted, this permits the bleaching gel to remain in contact with the teeth surface. In fact, this is the most pivotal aspect of the bleaching process and is the rationale why tray based bleaching systems have been so successful. This is perhaps the most cost effective method of tooth whitening now out there.

An OTC kit is similar to the take home whitening tray fitted at the dentist’s office, but in this case, you are totally on your own. You must thoroughly follow all the instructions. This method has been successful, but you should be cautious. This technique is not recommended by the ADA.

Dentist-supervised laser tooth whitening

With a procedure like Zoom® tooth whitening, a special bright laser light is shone on the teeth whitening gel for an hour. Laser light energy creates energy which initiates chemical reactions that cause the tooth whitening. Most people do a Zoom® tooth whitening once every six months. Judged against to OTC products, dentists for the most part use a higher concentration of bleaching compound with a laser tooth whitening system like Britesmile® or Zoom® tooth whitening. With a laser whitening technique, the precisely defined light frequency combined with a proprietary bleaching chemical produces very amplified whitening effects.
