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 get older. Teeth whitening is an effective course to reverse this process, and is so successful that 95% of persons going through the procedure do demonstrate some improvement. There is a great deal of tooth whitening systems available today. Tooth whitening systems provide a wide spectrum of alternatives, ranging from economical whitening strips on the low end to expensive but for the most part effective skilled dental whitening services.

Whitening Strip Method

The next simplest tooth whitening approach is the whitening strip method. 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 costly, and easiest to utilize tooth whitening system. This explains the popularity of this technique. But then, frequently the possible results are not as good as those results seen with the tray-based methods or in-office laser tooth whitening systems. Whitening strips might 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 might look similar to a bad cavity. If you don't utilize a tray-based tooth whitening system, you run the chance of experiencing irregular or spotty possible results.

OTC tooth whitening products ought to in principle provide the identical tooth whitening effect as a visit to a dentist office, however with a lessened concentration of the peroxide (5% - 10%), and over a longer period of time. This is partially true, but omits the fact that dentists use a laser tooth whitening system as well as bleach, something not available 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 significant aspect of the bleaching process and is the explanation why tray based bleaching systems have been so successful. This is maybe the most cost effective method of tooth whitening presently available. Through 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. 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 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 closely follow all the instructions. This method has been successful, but you must be cautious. This technique is not recommended by the ADA.

Dentist-supervised laser tooth whitening

With a procedure similar to 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. Compared to OTC products, dentists for the most part 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 exactly defined light frequency combined with a proprietary bleaching chemical produces particularly enhanced whitening effects.

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 a person ought to know in regards to the ADA seal of acceptance is that no OTC product has as of yet earned this coveted designation. Only particular 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. There are varying levels of quality to all these whitening systems. This is an area that the U.S. FDA doesn't become involved. Nonetheless, the American Dental Association (ADA) does set guidelines for tooth whitening products.

Tooth Whitening Toothpaste

The most basic tooth whitening approach is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you simply need some simple maintenance of prior tooth whitening, then this is the way to go. However, if the situation is more deep rooted, then more tooth whitening systems might be looked into.

Three Primary Approaches to Tooth Whitening

In the face of the perplexing array of dentist and over the counter (OTC) products, there are essentially only 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 administered whitening using OTC bleaching products

There is nothing intrinsically superior or unfavorable regarding any of these three basic approaches - each technique can yield decent results. You simply can’t put a bleaching agent on your teeth without a viable delivery system and presume it to work. The secret to the finest outcomes in tooth whitening is the whitening agent delivery system. 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.
