Laser Teeth Whitening: Safety Tips and Precautions

In a dentist’s office, a bleaching process called laser teeth whitening is performed. It differs from other teeth-whitening techniques since a bleaching gel and laser are used during the process. A laser is a very bright light beam. This article discusses the expenses, risks, and procedures associated with laser tooth whitening. It also specifies how long the effects should last.

Concerning laser teeth whitening

Your teeth can be made brighter with a process called laser teeth whitening. Another name for it is laser tooth whitening. Your teeth will be treated with a bleaching gel during the process. The gel is then heated by a laser that is pointed at your teeth. This changes the stain molecules on the teeth and activates its whitening powers. Reducing discoloration and improving the color of your teeth are the two main objectives of laser teeth whitening.

Tooth discoloration can occur due to various reasons, such as:

  • Ingesting specific foods and beverages, such as tea and coffee; smoking; growing older; oral injuries; and using specific drugs, such as chemotherapy and antihistamines
  • A 2014 literature analysis found that when whitening gels or UV radiation are used in place of other in-office procedures, the outcomes are roughly the same. 
  • According to a 2014 literature review, the American Dental Association does not support lasers since the Food and Drug Administration (FDA) views laser teeth whitening as an “off-label” use of lasers in dentistry. 

How is teeth whitening using a laser done?

Laser teeth whitening is only available in dental offices. Bleaching takes between thirty and sixty minutes. What exactly has to be done will determine the exact processes. What a typical course of treatment entails is this:

  • Your mouth will be propped open with a rubber or plastic device by your dentist.
  • They will then require you to wear safety glasses to keep your eyes safe.
  • Moreover, they will apply a gum barrier to keep your gums safe. A light-cured resin substance could be used as the barrier.
  • Your front teeth are treated with whitening gel by your dentist.
  • Your dentist applies a laser to your teeth a few minutes later.
  • The bleaching gel’s whitening effects are triggered when it is heated by the laser.
  • The gum barrier will be taken off and the bleaching gel will be rinsed away by your dentist.
  • Anecdotal evidence suggests that laser tooth whitening is painless. After the surgery, your teeth may feel more sensitive than usual for around twenty-four hours.

Bleaching teeth might harm the pulp or enamel of the teeth. The interior layer of a tooth, known as the pulp, is home to nerves and blood vessels. It’s crucial to refrain from bleaching your teeth too frequently to preserve them. The ideal frequency can be explained to you by a dentist with experience. Additionally, they can carry out the treatment in a method that keeps your gums and teeth safe.

What is the duration of it?

Teeth discoloration can be successfully decreased using laser teeth whitening. Stronger chemicals than those found in at-home whitening treatments are usually used in this technique. Consequently, compared to at-home procedures like using whitening toothpaste or strips every day, laser teeth whitening is more efficient and produces results more quickly.

The whitening results are transient, with a possible duration of three years to a few months. Compared to most other treatments, such as toothpaste and whitening strips, this one lasts longer.

  • The following variables will affect your findings and their duration:
  • the initial shade of your teeth how often you need treatments
  • Your way of living
  • the usage of lasers and bleaching gel
  • You’ll probably need three or four sessions in total for the best effects.

Modifying the subsequent behaviors could potentially aid in sustaining your outcomes:

  • Restricting or abstaining from using tobacco, such as cigarettes
  • Restricting or staying away from foods and beverages like coffee and red wine that discolor teeth
  • Lowering the possibility of oral damage, which can lead to more stains

What dangers exist?

Risks are associated with root canal treatment. Among the potential negative effects are:

  • heightened sensitivity of the teeth
  • gum irritation or harm to the oral tissues or pulp of teeth
  • loss of minerals and fluoride in teeth
  • elevated risk of decay or erosion of teeth

Furthermore, the process might not be appropriate if you:

  • Are you taking analgesic, anti-inflammatory, or antibiotic medications? Do you have tetracycline stains on your teeth? Do you have an orofacial tumor, tooth malformation, or mouth injury?
  • possess weakened enamel or visible dentin
  • Crowns and dentures are not compatible with laser teeth whitening. You may not be a good candidate for this operation if you have either device in your front teeth.


One type of cosmetic dentistry therapy is laser teeth whitening. Lasers and bleaching gel are used to lessen tooth discoloration. Your teeth may appear whiter and brighter as a result of this. Laser teeth whitening works better than at-home procedures like whitening strips. Nevertheless, the cost is higher, and dental insurance does not cover it. In addition, there is a chance of tooth decay, erosion, and heightened sensitivity following the surgery. Speak with a dentist to find out if laser teeth whitening is good for you.
