Why a Tooth Whitening System?

Why do teeth darken? This is because people 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 going through the process do verify some improvement. Tooth whitening systems provide a wide spectrum of alternatives, ranging from low-priced whitening strips on the low end to pricey but generally effective skilled dental whitening services. There is a plethora of tooth whitening systems obtainable today.

Whitening Strip Method

Whitening strips might accomplish a fine 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 could appear similar to a bad cavity. If you don't use a tray-based tooth whitening system, you run the risk of having irregular or spotty results. The next simplest tooth whitening system 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 employ tooth whitening procedure. This explains the popularity of this technique. But then, often the results are not as superb as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems.

OTC tooth whitening products should in principle provide the identical tooth whitening effect as a visit to a dentist office, however with a decreased 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

With a take home tooth whitening tray technique, 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 consequently worn for one to two hours at home at a convenient time by the tooth whitening patient. Because the bleaching tray is so custom fitted, this permits the bleaching gel to keep in contact with the teeth surface. Truly, this is the most important aspect of the bleaching process and is the explanation why tray based bleaching systems have been so successful. This is perhaps 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 completely on your own. You must carefully follow all the instructions. This technique has been successful, but you should be careful. This method 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 procedure, the exactly defined light frequency combined with a proprietary bleaching chemical produces particularly amplified whitening effects. 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 initiates chemical reactions that lead to the tooth whitening. A good number of people do a Zoom® tooth whitening once every six months.

Three Main Approaches to Tooth Whitening

Despite 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 tailored tray or a polyethylene strip
• Individual administered whitening using OTC bleaching products

The secret to the highest quality 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 method of delivery. This is with out a doubt needed to keep the gel in contact with the surface of the tooth. You just can’t put a bleaching agent on your teeth without a fine delivery procedure and presume it to work. There is nothing intrinsically good or deficient about any of these three basic approaches - each procedure should yield fine results.

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. There are varying degrees 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 turn out to be harmful to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What we should know in regards to the ADA seal of acceptance is that no OTC product has as of yet received this coveted designation.

Tooth Whitening Toothpaste

The most basic tooth whitening method is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you simply desire some uncomplicated maintenance of prior tooth whitening, then this is the direction to go. Yet, if the problem is more deep rooted, then additional tooth whitening systems should be looked into.

Conclusion

Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow carefully all instructions. Assess your circumstances. Providing you are looking for a bit of whitening of your teeth, then consider an OTC tooth whitening system. Provided that you really wish an excellent bright white smile, then your only option is a cosmetic dentist.
