Whitening tooth by bleaching

Whitening tooth by bleaching works because it actually makes teeth whiter. Its action is unlike those of  whitening toothpaste which merely removes surface stains to reveal the underlying whiteness of the teeth. The most common whitening tooth bleaching agents are carbamide peroxide and hydrogen peroxide.

However, whether teeth bleaching will be effective for your teeth depends very much on the colour of your teeth. This is because it works best for yellow stains. In the case of grey teeth, which may be due to certain antibiotics, they are more difficult to whiten.

Those of you who have stains from, say, smoking or drinking too much red wine or coffee can often get good results with teeth whitening.

So how does one go about whitening teeth? There are two ways to get whiter teeth - visit a dentist or use a home bleaching kit.
 
In the case of a dental visit, this is what they will do to whiten your teeth. The dentist will apply a whitening gel which contains a high concentration of hydrogen peroxide onto your teeth. This gel is then activated by shining a special blue-coloured high-intensity light or laser on it. This causes the gel to release oxygen molecules.

Don't worry about the laser. Its function is to activate the whitening tooth bleaching gel, and not to penetrate your teeth.

The end result depends a lot on the shade of your teeth before bleaching. While seeing a dentist is probably the best route to take to have whiter teeth, the current range of home teeth bleaching products after often safe and effective too, but it must be done properly.

A common method is the tray teeth whitening technique which involves using a plastic tray. The tray is filled with the bleaching gel and then fitted over the teeth. By keeping the bleaching gel in contact with the teeth for the prescribed duration, the teeth will supposedly get whiter.

People who uses teeth bleaching products should ideally ask for a dentist's advice before proceeding. This is important to avoid common side effects of teeth bleaching - increased tooth sensitivity and gum irritation. Sometimes, there may be extreme pain.

If you had sought the advice of dentists first, they may advise you on what to do in the event that your teeth become sensitive during the bleaching process.

Whitening tooth results vary from person to person, but there are many satisfied people out there. What if teeth bleaching does not work for you? Well, try veneers may be the best option then.
