Most people want whiter, brighter teeth but do not want to pay the outrageous prices charged by dental professionals. So they turn to a dental whitening system such as Crest White Strips or another commercial grade tooth bleaching system. But are these home kits actually better than going to a dentist for their professional teeth whitening techniques? Are they safe to use at home if you have a dental problem? Fortunately there are some answers to these questions.

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 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. The reason is that most people, after brushing their teeth at night, do not eat or drink anything until they wake in the morning, therefore leaving the whitening gel on the tooth surface longer.
