Laser teeth whitening, also known as laser teeth bleaching, is a cosmetic dental procedure performed in a dentist’s office. Unlike other teeth whitening methods, this procedure involves a bleaching gel and a laser, utilizing a beam of high-intensity light to enhance the whitening process. This article covers the process, potential side effects, associated costs, and the expected duration of results.

Understanding what is Laser Teeth Whitening?

Laser teeth whitening, also referred to as laser teeth bleaching, is meticulously designed to enhance the brightness of your teeth. The procedure involves the meticulous application of a bleaching gel onto your teeth, followed by the precise direction of a laser. The laser’s heat activates the gel’s whitening properties, orchestrating a transformation by altering stain molecules on the teeth.

The primary objective is to diminish discoloration, presenting teeth in a noticeably whiter and brighter light. Various factors contribute to tooth discoloration, encompassing dietary choices, tobacco use, aging, mouth injuries, and certain medications.

Procedure Overview: How Laser Teeth Whitening Works?

Dentist’s Expertise:

  • Laser teeth whitening mandates a dentist’s skill set and must be conducted within the confines of a dental office.
  • The procedure’s duration typically spans between 30 to 60 minutes.

Procedure Steps:

  • Placement of a rubber or plastic prop in the mouth to facilitate an open position.
  • Donning protective glasses to shield the eyes from laser exposure.
  • Application of a gum barrier, often a light-cured resin material, to protect the gums.
  • Precise application of a bleaching gel on the front teeth.
  • The strategic direction of a laser onto the teeth, intensifying the gel’s whitening properties.
  • Removal of the gum barrier and thorough rinsing to conclude the process.

Post-Procedure Sensitivity:


  • Laser teeth whitening, backed by anecdotal evidence, is typically painless.
  • Potential heightened tooth sensitivity may linger for about 24 hours post-procedure.

Preservation of Tooth Enamel:

  • To safeguard teeth, it is imperative to avoid excessive whitening frequency.
  • A seasoned dentist can offer insights into the optimal frequency, ensuring the procedure prioritizes teeth and gum protection.

Duration of Radiance: How long Teeth Whitening Lasts?

Laser teeth whitening present a formidable solution for effectively reducing teeth discoloration. With the utilization of potent chemicals surpassing those found in at-home treatments, laser teeth whitening stands out for its efficacy and prompt results, outshining alternatives like daily whitening strips or toothpaste.

The resulting brilliance is temporary, with effects lasting between a few months to an impressive 3 years. Factors influencing the longevity of results include the original color of teeth, treatment frequency, lifestyle habits, and the specifics of the bleaching gel and lasers employed. Optimal outcomes are often achieved through three to four sessions.

Maintaining the Brilliance: Post-Procedure Habits

  • Ensuring enduring brilliance involves mindful alterations to certain habits:
  • Limiting or abstaining from tobacco use, including cigarettes.
  • Restricting consumption of foods and beverages known to stain teeth, such as coffee or red wine.
  • Mitigating the risk of mouth trauma, a potential catalyst for increased stains.

Pros and Cons of Laser Teeth Whitening:


  • Expedited results surpassing at-home treatments.
  • Prolonged effects, enduring up to 3 years.
  • Administered by trained professionals.


  • Elevated costs relative to at-home treatments.
  • Possible need for multiple dental visits.
  • Potential escalation of gum irritation and tooth sensitivity.

Risks Associated with Laser Teeth Whitening

While laser teeth whitening yields remarkable results, it is not devoid of risks. Potential side effects encompass:

  • Increased tooth sensitivity.
  • Gum irritation or damage.
  • Potential damage to tooth pulp or mouth tissues.
  • Diminished fluoride and mineral levels in the teeth.
  • Elevated risks of tooth erosion or decay.

Laser teeth whitening might not be suitable if you:

  • Are undergoing orthodontic treatment
  • Have tetracycline stains on your teeth
  • Have an orofacial tumor, tooth malformation, or mouth injury
  • Are taking specific medications
  • Have exposed dentin or weak enamel

Final Takeaway

In essence, laser teeth whitening emerges as a pivotal cosmetic dental procedure, harmonizing the use of bleaching gel and lasers to mitigate teeth discoloration. Its prowess transcends the efficacy of at-home treatments, albeit at a higher cost, and remains outside the purview of dental insurance coverage.

While delivering transformative brilliance, the procedure is not without potential side effects, such as heightened tooth sensitivity, erosion, and decay. To ascertain the appropriateness of laser teeth whitening for your unique dental profile, a thorough discussion with a mission implant center is indispensable.
