Why a Tooth Whitening System?
Why do teeth darken? This is because individuals consume caffeine-containing drinks, smoke, become exposed to antibiotics, and just plain get older. Teeth whitening is an effective technique to reverse this process, and is so successful that 95% of persons undergoing the process do show some improvement. There is a plethora of tooth whitening systems available today. Tooth whitening systems offer a wide spectrum of alternatives, ranging from inexpensive whitening strips on the low end to expensive but for the most part effective expert dental whitening services.
Whitening Strip Method
Whitening strips are able to accomplish a good 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 could appear similar to a bad cavity. If you do not use a tray-based tooth whitening system, you run the chance of having irregular or spotty consequences. The next simplest tooth whitening method is the whitening strip approach. 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 pricey, and easiest to use tooth whitening approach. This explains the popularity of this approach. However, often the outcomes aren't as good as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems.
OTC tooth whitening products could in principle come up with 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 time period. 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.
The ADA Seal of Acceptance
Only certain 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. The ADA guideline for a whitener requires that it not be adverse to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What we must know about the ADA seal of acceptance is that no OTC product has as of yet attained this coveted designation. There are varying levels of value to all these whitening systems. This is an area that the U.S. FDA doesn't get involved. Nonetheless, the American Dental Association (ADA) does set guidelines for tooth whitening products.
Tooth Whitening Toothpaste
The most uncomplicated tooth whitening method is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you simply want some simple maintenance of prior tooth whitening, then this is the direction to go. But, if the situation is more deep rooted, then further tooth whitening systems might be looked into.
Take Home Tray Whitening
As the bleaching tray is so custom fitted, this permits the bleaching gel to keep in contact with the teeth surface. In essence, this is the most vital 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 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. 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 then 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 thoroughly follow all the instructions. This procedure has been successful, but you should be careful. This method 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 lead to the tooth whitening. A large number of people do a Zoom® tooth whitening once every six months. Contrasted to OTC products, dentists mostly use a higher concentration of bleaching compound with a laser tooth whitening system like Britesmile® or Zoom® tooth whitening. With a laser whitening system, the precisely defined light frequency combined with a proprietary bleaching chemical produces very enhanced whitening effects.

Three Main Approaches to Tooth Whitening
In the face of the confusing array of dentist and over the counter (OTC) products, there are practically just 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 administered whitening using OTC bleaching products
There is not anything intrinsically good or deficient about any of these three basic approaches - each procedure should yield fine outcomes. The secret to the most ideal 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 method of delivery. This is definitely central to keep the gel in contact with the surface of the tooth. You clearly can’t put a bleaching agent on your teeth without a fine delivery system and presume it to work.
Conclusion
Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow closely all instructions. Assess your situation. Only if you are looking for a bit of whitening of your teeth, then consider an OTC tooth whitening system. Provided that you particularly want an excellent bright white smile, at that time your sole choice is a cosmetic dentist.
