A protective barrier is put in place around your gums and your lips to protect them from the bleach. At this point, your teeth get covered in bleach.

The bleach used contains a high concentration of hydrogen peroxide. A very high strength light is then used to activate the bleach.

This process is usually repeated several times to achieve the desired shade. This is the process behind laser teeth whitening. As the bleach and the light used are both quite strong, the whitening process is more rapid than other techniques.

When a properly trained and certified dentist performs laser teeth whitening, there are several advantages.

• Noticeable results develop within a single laser teeth whitening session.
• The dentist does all the work in the office, so the patient does not have to use any materials or techniques at home.
• The whitening results are faster than those achieved by take-home products.
• Having a dentist perform the procedure reduces the risk of complications like soft tissue burns or damage to the nerves inside the teeth.

You need to follow these few steps to maintain a healthy whiter smile:

• Avoid stain-causing beverages and foods: It includes hard candy, wine, tea, coffee, sports drinks, tomato sauce, berries, etc.
