Why a Tooth Whitening System?

There is a good amount of of tooth whitening systems available currently. Tooth whitening systems offer a wide spectrum of alternatives, ranging from low cost whitening strips on the low end to expensive but mostly effective expert dental whitening services. Why do teeth darken? This is because people 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 undergoing the process do show some improvement.

The ADA Seal of Acceptance

Only a small amount of 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. There are varying degrees of worth to all these whitening systems. This is an area that the U.S. FDA doesn't get involved. Nevertheless, the American Dental Association (ADA) does set guidelines for tooth whitening products. The ADA guideline for a whitener requires that it not be harmful to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What a person should know in regards to the ADA seal of acceptance is that no OTC product has yet received this coveted designation.

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 just require some simple maintenance of prior tooth whitening, then this is the direction to go. But, if the difficulty is more deep rooted, then more tooth whitening systems ought to be looked into.

Whitening Strip Method

Whitening strips can accomplish 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 seem similar to a bad cavity. If you do not employ a tray-based tooth whitening system, you run the risk of dealing with irregular or spotty possible results. The next simplest tooth whitening technique 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 costly, and easiest to use tooth whitening technique. This explains the popularity of this technique. However, frequently the 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 ought to in principle provide the identical tooth whitening effect as a visit to a dentist office, but with a lessened concentration of the peroxide (5% - 10%), and over a longer time period. This is partially true, but omits the fact that dentists employ a laser tooth whitening system as well as bleach, something unavailable with OTC products.

Take Home Tray Whitening

Due to the fact that the bleaching tray is so custom fitted, this allows the bleaching gel to stay in contact with the teeth surface. In fact, this is the most pivotal aspect of the bleaching process and is the explanation why tray based bleaching systems have been so successful. This is probably 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. Then, 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.

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 carefully follow all the instructions. This method has been successful, but you must be cautious. This method 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 causes chemical reactions that cause the tooth whitening. Most 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 process, the precisely defined light frequency combined with a proprietary bleaching chemical produces exceptionally enhanced whitening effects.

Three Primary Approaches to Tooth Whitening

In the face of the bewildering array of dentist and over the counter (OTC) products, there are in essence simply 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 results 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 with out a doubt 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 good delivery technique and expect it to work. There is nothing intrinsically superb or deficient regarding any of these three basic techniques - each method can yield superb outcomes.
