Why a Tooth Whitening System?

There is a plethora of tooth whitening systems obtainable today. Tooth whitening systems provide a wide spectrum of alternatives, ranging from low cost whitening strips on the low end to costly but generally effective specialized dental whitening services. Why do teeth become yellowed? This is because individuals consume caffeine-containing drinks, smoke, get exposed to antibiotics, and just plain age. Teeth whitening is an effective path to reverse this process, and is so successful that 95% of those undergoing the approach do show some improvement.

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 one must know in regards to the ADA seal of acceptance is that no OTC product has as of yet received this coveted designation. There are varying degrees of value to all these whitening systems. This is an area that the U.S. FDA doesn't get involved. At any rate, the American Dental Association (ADA) does set rules for tooth whitening products. Only particular tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners which have attained 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 desire some uncomplicated maintenance of prior tooth whitening, then this is the way to go. Yet, if the problem is more deep rooted, then other tooth whitening systems ought to be looked into.

Take Home Tray Whitening

Because the bleaching tray is so custom fitted, this permits the bleaching gel to remain in contact with the teeth surface. Actually, 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 now on hand. Through 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. 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 approach has been successful, but you should be careful. This system is not recommended by the ADA.

Dentist-supervised laser tooth whitening

Compared 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 technique, the exactly defined light frequency combined with a proprietary bleaching chemical produces especially enhanced whitening effects. 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 cause the tooth whitening. A good number of people do a Zoom® tooth whitening once every six months.

Three Primary Approaches to Tooth Whitening

Despite 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 directed whitening using OTC bleaching products

You clearly can’t put a bleaching agent on your teeth without a fine delivery technique and presume it to work. There's not anything intrinsically superior or unfavorable about any of these three basic techniques - each approach could yield superb results. The secret to the most ideal results 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 procedure of delivery. This is absolutely needed to keep the gel in contact with the surface of the tooth.

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 pricey, and easiest to employ tooth whitening system. This explains the popularity of this method. But then, frequently the possible results aren't as excellent as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems. 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 look similar to a bad cavity. If you do not utilize a tray-based tooth whitening system, you run the risk of experiencing irregular or spotty results.

OTC tooth whitening products should in principle provide the identical tooth whitening effect as a visit to a dentist office, yet 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 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 in detail all instructions. Evaluate your circumstances. If you are looking for a bit of whitening of your teeth, then think about an OTC tooth whitening system. Provided that you truly seek a wonderful bright white smile, at that time your sole choice is a cosmetic dentist.
