Why a Tooth Whitening System?
Why do teeth darken? This is because individuals consume caffeine-containing drinks, smoke, get exposed to antibiotics, and just plain age. Teeth whitening is an effective path to reverse this process, and is so successful that 95% of persons going through the process do confirm some improvement. Tooth whitening systems offer a wide spectrum of alternatives, ranging from inexpensive whitening strips on the low end to costly but for the most part effective professional dental whitening services. There is a plethora of tooth whitening systems accessible currently.
Whitening Strip Method
Whitening strips can accomplish a good 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 seem similar to a bad cavity. If you do not utilize a tray-based tooth whitening system, you run the risk of experiencing irregular or spotty possible results. The next simplest tooth whitening system is the whitening strip system. 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 use tooth whitening technique. This explains the popularity of this system. But then, often the possible results are not as superb as those results 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 decreased concentration of the peroxide (5% - 10%), and over a longer time period. This is partially true, but omits the reality that dentists use a laser tooth whitening system as well as bleach, something unavailable with OTC products.
Take Home Tray Whitening
Because the bleaching tray is so custom fitted, this permits the bleaching gel to keep in contact with the teeth surface. In fact, this is the most essential 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 currently 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. Then, a perfect fitting bleach tray is fitted from this impression. Lastly, 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 utterly on your own. You must thoroughly follow all the instructions. This method has been successful, but you should be cautious. This approach is not recommended by the ADA.
Dentist-supervised laser tooth whitening
Contrasted to OTC products, dentists usually use a higher concentration of bleaching compound with a laser tooth whitening system like Britesmile® or Zoom® tooth whitening. With a laser whitening procedure, the precisely defined light frequency combined with a proprietary bleaching chemical produces exceptionally amplified whitening effects. 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 causes chemical reactions that cause the tooth whitening. Most people do a Zoom® tooth whitening once every six months.

Three Main Approaches to Tooth Whitening
In the face of the perplexing array of dentist and over the counter (OTC) products, there are in point of fact 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 directed whitening using OTC bleaching products
There is nothing intrinsically superb or unfavorable about any of these three basic approaches - each procedure can yield nice results. You simply can’t put a bleaching agent on your teeth without a good delivery technique and expect it to work. The secret to the best outcomes in tooth whitening is the whitening agent delivery procedure. In all the tooth whitening methods, the tooth bleaching gel is kept in place by a system 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 we should know regarding the ADA seal of acceptance is that no OTC product has as of yet earned this coveted designation. Only certain tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners that have earned the ADA Seal, the active ingredient is a 10% carbamide peroxide solution. There are varying levels of worth to all these whitening systems. This is an area that the U.S. FDA does not get involved. At any rate, the American Dental Association (ADA) does set guidelines for tooth whitening products.
Tooth Whitening Toothpaste
The most simple tooth whitening approach is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you simply require some uncomplicated maintenance of prior tooth whitening, then this is the direction to go. But, if the problem is more deep rooted, then further tooth whitening systems might be looked into.
Conclusion
Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow carefully all instructions. Analyze your circumstances. If you are looking for a small amount of whitening of your teeth, then contemplate an OTC tooth whitening system. If you truly seek an excellent bright white smile, then your sole choice is a cosmetic dentist.
