Why a Tooth Whitening System?

There is a great deal of tooth whitening systems obtainable today. Tooth whitening systems provide a wide spectrum of alternatives, ranging from inexpensive whitening strips on the low end to expensive but usually effective expert dental whitening services. Why do teeth become yellowed? This is due to the fact that people consume caffeine-containing drinks, smoke, become exposed to antibiotics, and just plain age. Teeth whitening is an effective technique to reverse this process, and is so successful that 95% of those going through the process do demonstrate some improvement.

Three Main Approaches to Tooth Whitening

In the face of the bewildering array of dentist and over the counter (OTC) products, there are in point of fact 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

There is nothing intrinsically superb or deficient about any of these three basic techniques - each method can yield fine results. You simply can’t put a bleaching agent on your teeth without a viable delivery system and expect it to work. The secret to the best results in tooth whitening is the whitening agent delivery technique. In all the tooth whitening methods, the tooth bleaching gel is kept in place by a system of delivery. This is unquestionably necessary to keep the gel in contact with the surface of the tooth.

Take Home Tray Whitening

With a take home tooth whitening tray method, 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 consequently worn for one to two hours at home at a convenient time by the tooth whitening patient. As the bleaching tray is so custom fitted, this permits 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 presently on hand.

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 technique has been successful, but you must 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 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 process, the precisely defined light frequency combined with a proprietary bleaching chemical produces especially amplified whitening effects.

The ADA Seal of Acceptance

There are differing levels of quality to all these whitening systems. This is an area that the U.S. FDA doesn't become involved. Nevertheless, the American Dental Association (ADA) does set rules for tooth whitening products. The ADA guideline for a whitener requires that it not become bad to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What we must know in regards to the ADA seal of acceptance is that no OTC product has yet received this coveted designation. Only certain tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners that have received the ADA Seal, the active ingredient is a 10% carbamide peroxide solution.

Tooth Whitening Toothpaste

The most basic tooth whitening system is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you just require some uncomplicated maintenance of prior tooth whitening, then this is the direction to go. However, if the situation is more deep rooted, then more tooth whitening systems ought to be looked into.

Whitening Strip Method

Whitening strips might do a nice 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 may appear similar to a bad cavity. If you do not use a tray-based tooth whitening system, you run the risk of having irregular or spotty consequences. The next simplest tooth whitening approach is the whitening strip system. 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 utilize tooth whitening technique. This explains the popularity of this system. Yet, frequently the outcomes are not as excellent as those outcomes 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, 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 utilize a laser tooth whitening system as well as bleach, something not available with OTC products.

Conclusion

Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow in detail all instructions. Take a look at your condition. Only if you are looking for a little whitening of your teeth, then think about an OTC tooth whitening system. If you truly seek a superb bright white smile, then your sole choice is a cosmetic dentist.
