A professional dental whitening system is very costly and with many of the treatments requiring more than one visit to the dentist, the whole treatment can often cost in excess of $1,000. This is why a lot of people are choosing a home teeth whitening product, such as Crest White Strips or a similar kit, which will lighten the color of the teeth.
If you wish to know how these teeth whitening products work, then just read further and you will find out how you can save yourself an expensive visit to a cosmetic dentist but still have an attractive white smile.
Once upon a time, the dental whitening system worked through the use of a plastic tray and bleaching gel. The contraption was molded to each individual's mouth and the tray, after filling it with the special whitening gel, was left in overnight. Unfortunately, the gel lost its effectiveness after a few hours and there was also irritation to the gums and throat from the substance being in the mouth for such a prolonged period of time.
Items such as Crest White Strips have eliminated the need for the bulky whitening trays and bleach that stayed on overnight. These whitening strips are applied to the teeth and then left on for fifteen to thirty minutes twice a day. Some of the new lines are applied only at night.
Some of the newer versions need only be applied at night and this is because most people brush their teeth just before going to bed and then don't eat anything until the next morning. This enables them to leave the strips on the surface of the teeth for a longer period of time.
Teeth whitening kits also are produced in generic versions such as Equate found at Wal-Mart. Truth be told, they can be just as effective as their brand name counterparts. If you are unsure if a generic teeth whitening kit is of the same quality as a brand name, then take a look at the ingredients list. Chances are the active ingredients are the same for both brand and generic and you may actually save a few extra dollars with the generic kit.
If in the past you have encountered enamel problems with your teeth, the use of a dental whitening system may not be recommended. The gel can cause irritation, pain and in some instances, an allergic reaction may be the result of using this kind of product.
On the other hand most people do not experience problems when using these kits and take advice from the dentist about which tooth whitening product best suits them, taking into account their dental history.
