Why a Tooth Whitening System?
Tooth whitening systems offer a wide spectrum of alternatives, ranging from economical whitening strips on the low end to expensive but mostly effective specialized dental whitening services. Why do teeth become yellowed? This is due to the fact that people 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 experiencing the process do show some improvement. There is a large amount of of tooth whitening systems to be had currently.
The ADA Seal of Acceptance
Only particular tray-based dentist-dispensed products have the ADA Seal. In all the at-home tooth whiteners which have acquired the ADA Seal, the active ingredient is a 10% carbamide peroxide solution. The ADA guideline for a whitener requires that it not be adverse to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What a person must know about the ADA seal of acceptance is that no OTC product has yet earned this coveted designation. There are varying levels of quality to all these whitening systems. This is an area that the U.S. FDA doesn't become involved. At any rate, the American Dental Association (ADA) does set guidelines for tooth whitening products.
Tooth Whitening Toothpaste
The most uncomplicated tooth whitening approach is tooth whitening toothpaste (which is a mix of hydrogen peroxide and baking soda). If you merely desire some simple maintenance of prior tooth whitening, then this is the way to go. However, if the difficulty is more deep rooted, then further tooth whitening systems should be looked into.
Three Primary Approaches to Tooth Whitening
Despite the confusing array of dentist and over the counter (OTC) products, there are actually 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 just can’t put a bleaching agent on your teeth without a viable delivery procedure and presume it to work. There is nothing intrinsically good or unfavorable about any of these three basic techniques - each system should yield superb results. The secret to the best 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 system of delivery. This is unquestionably needed to keep the gel in contact with the surface of the tooth.
Whitening Strip Method
The next simplest tooth whitening system is the whitening strip procedure. 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 technique. This explains the popularity of this approach. But then, often the results aren't as nice as those outcomes seen with the tray-based methods or in-office laser tooth whitening systems. Whitening strips might accomplish a fine 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 appear similar to a bad cavity. If you don't employ a tray-based tooth whitening system, you run the possibility of having irregular or spotty results.
OTC tooth whitening products can in principle provide the identical tooth whitening effect as a visit to a dentist office, yet with a lowered concentration of the peroxide (5% - 10%), and over a longer time period. This is partially true, but omits the reality that dentists employ a laser tooth whitening system as well as bleach, something unavailable with OTC products.
Take Home Tray Whitening
As the bleaching tray is so custom fitted, this permits the bleaching gel to stay in contact with the teeth surface. Actually, this is the most vital aspect of the bleaching process and is the rationale why tray based bleaching systems have been so successful. This is perhaps the most cost effective method of tooth whitening currently 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. Subsequently, 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 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 thoroughly follow all the instructions. This procedure has been successful, but you must be careful. This system 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. A good number of people do a Zoom® tooth whitening once every six months. Compared 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 technique, the exactly defined light frequency combined with a proprietary bleaching chemical produces very amplified whitening effects.
