Why a Tooth Whitening System?
Tooth whitening systems provide a wide spectrum of alternatives, ranging from inexpensive whitening strips on the low end to costly but typically effective skilled dental whitening services. Why do teeth darken? This is due to the fact that people consume caffeine-containing drinks, smoke, become exposed to antibiotics, and just plain get older. Teeth whitening is an effective course to reverse this process, and is so successful that 95% of those going through the process do show some improvement. There is a great deal of tooth whitening systems accessible currently.
Whitening Strip Method
Whitening strips might 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 might appear like a bad cavity. If you don't employ a tray-based tooth whitening system, you run the chance of dealing with irregular or spotty possible results. The next simplest tooth whitening approach is the whitening strip procedure. You place tooth bleaching tape on your front teeth. This tape is flexible, and contains the gel which bleaches the teeth. This is the most comfortable, least pricey, and easiest to utilize tooth whitening procedure. This explains the popularity of this technique. But then, frequently the results aren't as good as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems.
OTC tooth whitening products can in principle come up with the identical tooth whitening effect as a visit to a dentist office, yet with a lower concentration of the peroxide (5% - 10%), and over a longer period of time. This is partially true, but omits the reality that dentists use a laser tooth whitening system as well as bleach, something not available with OTC products.
Take Home Tray Whitening
As the bleaching tray is so custom fitted, this permits the bleaching gel to remain in contact with the teeth surface. Actually, this is the most important aspect of the bleaching process and is the rationale why tray based bleaching systems have been so successful. This is maybe the most cost effective method of tooth whitening right now on hand. 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 subsequently worn for one to two hours at home at a convenient time by the tooth whitening patient.
An OTC kit is similar to the take home whitening tray fitted at the dentist’s office, but in this case, you are completely on your own. You must closely follow all the instructions. This approach has been successful, but you should be cautious. This approach is not recommended by the ADA.
Dentist-supervised laser tooth whitening
With a procedure such as 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 lead to the tooth whitening. A good number of people do a Zoom® tooth whitening once every six months. Judged against to OTC products, dentists typically 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 exactly defined light frequency combined with a proprietary bleaching chemical produces exceptionally enhanced whitening effects.

The ADA Seal of Acceptance
The ADA guideline for a whitener requires that it not turn out to be harmful to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What one should know regarding the ADA seal of acceptance is that no OTC product has as of yet received this coveted designation. There are varying degrees of quality to all these whitening systems. This is an area that the U.S. FDA does not get involved. Nevertheless, 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 attained the ADA Seal, the active ingredient is a 10% carbamide peroxide solution.
Tooth Whitening Toothpaste
The most simple tooth whitening technique is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you merely want some simple maintenance of prior tooth whitening, then this is the way to go. However, if the difficulty is more deep rooted, then more tooth whitening systems should be looked into.
Three Primary Approaches to Tooth Whitening
Notwithstanding the confusing array of dentist and over the counter (OTC) products, there are actually just three (3) approaches to whitening one’s teeth:
- Dental in-office bleaching
- Self-applied night-time bleaching using a custom-fitted tray or a polyethylene strip
- Individual administered whitening using OTC bleaching products
The key to the highest quality outcomes in tooth whitening is the whitening agent delivery system. In all the tooth whitening methods, the tooth bleaching gel is kept in place by a method of delivery. This is unquestionably needed to keep the gel in contact with the surface of the tooth. There is not anything intrinsically superior or unfavorable about any of these three basic approaches - each method can yield nice results. You just can’t put a bleaching agent on your teeth without a fine delivery technique and presume it to work.
Conclusion
Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow in detail all instructions. Review your circumstances. If you are looking for a little whitening of your teeth, then think about an OTC tooth whitening system. If you particularly desire a wonderful bright white smile, at that time your only choice is a cosmetic dentist.
