Teeth bleaching is a way to lighten natural tooth color that makes the smile more beautiful. We sometimes want to whiten our teeth that have lost their beauty due to smoking or aging, and drinks and food stains. Teeth whitening or bleaching can also be done with a laser. In dentistry, this method involves lightening the enamel and the teeth dentin. According to an experienced Toronto teeth whitening group of dentists, the teeth’ color can be whitened by two to six degrees in the shortest possible time using the laser bleaching method. So if you have yellow teeth, using this method is recommended for you.

Causes of teeth bad color

Several factors cause yellowing of the teeth over time, including the following:

• Natural changes in tooth color (inner part of the tooth) with age
• Excessive beverages and foods with strong colored substances such as carrots, oranges, chocolate, tea, and coffee in the diet
• Smoking that makes teeth yellow.
• Teeth tartar or dental calculus: A plaque that usually builds up on the tooth’s surface due to improper brushing.
• Fillers used to treat root canal or neurosurgery
• Taking medications such as antibiotics during tooth growth and development

How is laser teeth whitening done?

A specialist in dentistry does this method. In this method, the bleach is first placed on the teeth, and then the laser beam will be shone on them. Thus laser treatment will be done at a much higher speed. The bleaching and laser teeth whitening results are more powerful than the simple method because the bleaching gel is more powerful.

The bleaching agent used for the laser contains hydrogen peroxide, this substance decomposes in the tooth, and the resulting oxygen will reach the enamel and the tooth dentin. This process is done without any damage and change to the tooth structure, and only the colored material on the teeth will be changed. The laser light in this process helps to absorb hydrogen peroxide better and also helps whiten teeth more.

Laser in teeth whitening and bleaching has different types with different results. In this regard, the dentist finds out which laser for their treatment is more appropriate according to the clients’ teeth and hearing their expectations from the amount of teeth whitening.
