Why a Tooth Whitening System?
There is a great deal of tooth whitening systems to be had currently. Why do teeth become yellowed? This is because individuals consume caffeine-containing drinks, smoke, become 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 experiencing the procedure do verify some improvement. Tooth whitening systems offer a wide spectrum of alternatives, ranging from inexpensive whitening strips on the low end to pricey but usually effective expert dental whitening services.
The ADA Seal of Acceptance
The ADA guideline for a whitener requires that it not be bad to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What we should know about the ADA seal of acceptance is that no OTC product has 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 doesn't become involved. At any rate, the American Dental Association (ADA) does set rules for tooth whitening products. Only a small amount of tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners which have acquired 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 just require some simple maintenance of prior tooth whitening, then this is the way to go. But, if the situation is more deep rooted, then further tooth whitening systems might be looked into.
Take Home Tray Whitening
Because the bleaching tray is so custom fitted, this allows the bleaching gel to stay in contact with the teeth surface. Actually, this is the most critical aspect of the bleaching process and is the explanation why tray based bleaching systems have been so successful. This is possibly the most cost effective method of tooth whitening currently out there. Through a take home tooth whitening tray technique, which the patient can perform at home, the dentist makes an impression for a model of the patient’s teeth. Subsequently, 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 procedure has been successful, but you should be careful. 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 causes chemical reactions that cause the tooth whitening. The majority of people do a Zoom® tooth whitening once every six months. Contrasted 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 precisely defined light frequency combined with a proprietary bleaching chemical produces exceptionally enhanced whitening effects.

Three Primary Approaches to Tooth Whitening
Notwithstanding the confusing 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
The secret to the best outcomes in tooth whitening is the whitening agent delivery method. In all the tooth whitening methods, the tooth bleaching gel is kept in place by a system of delivery. This is absolutely central to keep the gel in contact with the surface of the tooth. You just can’t put a bleaching agent on your teeth without a good delivery technique and presume it to work. There is not anything intrinsically superb or unfavorable about any of these three basic approaches - each system should yield fine results.
Whitening Strip Method
Whitening strips might do a fine job of whitening the exterior tooth surfaces, but do a poor job of bleaching the teeth divisions and cracks. A dark division between whitened teeth might look similar to a bad cavity. If you don't employ a tray-based tooth whitening system, you run the risk of having irregular or spotty possible results. The next simplest tooth whitening method 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 employ tooth whitening method. This explains the popularity of this technique. Yet, frequently the results aren't as nice as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems.
OTC tooth whitening products can in principle provide the identical tooth whitening effect as a visit to a dentist office, but with a decreased concentration of the peroxide (5% - 10%), and over a longer period of time. This is partially true, but omits the reality that dentists utilize a laser tooth whitening system as well as bleach, something unavailable with OTC products.
Conclusion
Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow closely all instructions. Review your circumstances. Only if you are looking for a small amount of whitening of your teeth, then contemplate an OTC tooth whitening system. If you really desire a magnificent bright white smile, then your only option is a cosmetic dentist.
