Why a Tooth Whitening System?

There is a good amount of of tooth whitening systems to be had today. Why do teeth darken? This is because people consume caffeine-containing drinks, smoke, get exposed to antibiotics, and just plain get older. Teeth whitening is an effective technique to reverse this process, and is so successful that 95% of persons going through the procedure do show some improvement. Tooth whitening systems offer a wide spectrum of alternatives, ranging from economical whitening strips on the low end to costly but mostly effective professional dental whitening services.

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 obtained the ADA Seal, the active ingredient is a 10% carbamide peroxide solution. The ADA guideline for a whitener requires that it not turn out to be bad to the soft tissues of the mouth or the teeth, and that a whitener can effectively whiten teeth. What we ought to know regarding the ADA seal of acceptance is that no OTC product has yet earned this coveted designation. There are differing degrees of value to all these whitening systems. This is an area that the U.S. FDA does not become involved. Nevertheless, the American Dental Association (ADA) does set rules for tooth whitening products.

Tooth Whitening Toothpaste

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

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. In fact, this is the most essential aspect of the bleaching process and is the rationale why tray based bleaching systems have been so successful. This is probably the most cost effective method of tooth whitening right now on hand. Through 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. Subsequently, 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 subsequently 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 totally on your own. You must thoroughly follow all the instructions. This method has been successful, but you must be careful. This approach 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 cause the tooth whitening. A good number of people do a Zoom® tooth whitening once every six months. Contrasted to OTC products, dentists usually 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 very enhanced whitening effects.

OTC gels	Improves with higher peroxide levels	1 year	1-3 weeks	Sensitive teeth/gums	Moderately yellow to dark teeth	$10
Bleaching done in dentist's office	Great for yellow teeth	3 yrs	1-2 mos.	Sensitive teeth/gums	Extremely dark teeth, which require professional evaluation	$300-$1000
Dentist supervised gel application	Great for yellow teeth	3 years	3-6 wks	Sensitive teeth/gums	Dark teeth, which needs a dentist-supervised evaluation	$300-$500
Crowns	Very effective for one tooth	10-15 years	1 month	feeling of tightness	Single tooth is decayed or broken	$600-$3000
Veneers	Very effective for just one tooth	10-15 years	3-4 weeks	feeling of tightness	Single tooth needs straightening	$500-$1200
Bonding	Very effective for just one tooth	5-10 years	1-2 weeks	Rare allergies	Single tooth needs minor reshaping	$300-$700

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 expensive, and easiest to use tooth whitening system. This explains the popularity of this technique. But then, often the possible 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 good 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 may seem similar to a bad cavity. If you do not utilize a tray-based tooth whitening system, you run the chance of having irregular or spotty consequences.

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 fact that dentists utilize a laser tooth whitening system as well as bleach, something not available with OTC products.

Three Primary Approaches to Tooth Whitening

In the face of the bewildering array of dentist and over the counter (OTC) products, there are practically 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 not anything intrinsically superior or bad regarding any of these three basic techniques - each technique should yield superb outcomes. 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 method of delivery. This is definitely fundamental 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 good delivery procedure and expect it to work.

Conclusion

Whatever tooth whitening system you prefer, always seek the advice of your dentist and follow closely all instructions. Assess your circumstances. Providing you are looking for a little whitening of your teeth, then consider an OTC tooth whitening system. Provided that you truly want a superb bright white smile, then your only choice is a cosmetic dentist.
