For people who want a smile that is brighter, the process of tooth whitening can be easily administered. Tooth whitening can reduce staining and discoloration and ultimately grant a patient a whiter and brighter set of teeth.

But how much really can your teeth become whiter? Some tooth whitening products claim that your teeth can become nine shades whiter. This is exaggerating. A whitening of two or three shades is more possible and can already provide a significant change in a person's smile.

It is important to note at this point that our teeth have no uniform whiteness. Usually, the whitest teeth are the two front teeth while molars are generally two shades darker. A realistic goal for anyone wishing to have a whiter set of teeth is for the process to achieve its optimum level while retaining the natural look of white teeth. Besides, the whitening results vary from patient to patient depending on the teeth structure and procedure type.

But first, what causes tooth discoloration? Remember that aging, chemical damage and staining are factors that contribute to discoloration as are medications, tea, coffee, cola soft drinks and cigarette.

There are also other factors that affect the color of teeth like genetics and disease. Some people have naturally whiter teeth enamel and their children can acquire this gene trait. But if you suspect that there's a physiological factor behind the color of your teeth, it is best to consult your physician too so you can better inform your dentist.

Teeth whitening corrects the discoloration in your teeth by removing the staining on your teeth. And there are a number of methods or techniques that can be used to achieve this such as the following: mild acid whitening, chemical whitening, abrasive teeth whitening and the latest one: laser teeth whitening.

Teeth bleaching is a chemical process that a dentist can use to lighten up the color of the teeth of his patient. The process can be administered right in the dentist's clinic, at the patient's home or a combination of clinic first-finish at home. Home teeth bleaching procedures are more common nowadays these afford patients the convenience of their own homes.

The cosmetic dentist first molds a custom mouth tray or mouth guard for his patient. Creating the mouth tray is critical because this controls the amount of whitening agent to be used and holds the entire teeth for even whitening. Other material requirements for the home procedure are fairly easy to handle. The dentists should make sure that the patient is well-instructed and well-equipped. While treating at home, never hesitate to call your dentist if you have questions or is not sure of what you're doing.

Typically, the mouthguard containing the whitening solution must be worn overnight or as instructed by your dentist and/or recommended by the product literature. The session could also last for as short as 2 or 3 hours. This really depends in the product and your own whitening need.
