Understanding Laser Teeth Whitening vs Bleaching

If you want those pearly-white teeth and are prepared to go beyond conventional whitening techniques of using over-the-counter strips and toothpaste, you should consider consulting professional teeth whiteners. Teeth whitening is a popular cosmetic dental procedure aimed at enhancing the colour and aesthetics of teeth. Among the various methods available, laser teeth whitening and traditional bleaching stand out as two of the most common options.

However, you have to make some crucial decisions when you visit the dentist. Should you spend money on laser teeth whitening or get your teeth professionally whitened using bleaching trays? It’s a huge decision that will impact both your smile and your pocket. Ensure that you are conversant with the advantages and disadvantages of every method and then select the one that best suits your needs and your budget. In this read, we will look at the differences between the two methods, their effectiveness, and what to expect from each procedure.

Teeth Bleaching

Teeth bleaching is a process that uses chemical agents, primarily hydrogen peroxide or carbamide peroxide, to break down stains on the enamel of teeth. This method can be performed in two main ways:

In-Office Bleaching: Conducted by a dental professional, this method typically involves applying a concentrated bleaching gel to the teeth, which may be activated by a light source.

At-Home Bleaching: Patients use custom-fitted trays or over-the-counter products like strips and gels. This method is more time-consuming and can take several weeks to achieve noticeable results14.

The bleaching agents work by releasing oxygen molecules that penetrate the enamel, neutralizing stains from within. While effective for moderate staining, this method often requires multiple sessions to achieve desired results.

Laser Teeth Whitening

Most people are under the preconception that laser whitening involves the use of lasers where dirt is blasted off your teeth. That is science fiction and simply not how laser teeth whitening works. A hydrogen peroxide-based gel is applied to the teeth.

The only thing the lasers do is heat the oxygen molecules in peroxide paste, which speeds up the discoloration process. The dentist applies either an argon laser or a carbon dioxide (CO2) laser to the bleaching trays to accelerate the chemical process that the bleach has already initiated. Laser teeth whitening may completely eliminate stains from your teeth by undergoing 30-minute sessions, often performed once every ten days or so. It works so well because it accelerates the bleaching process. To avoid having to sleep with bleaching trays in their mouths, some people opt for laser whitening. This potential advantage would be eliminated, though, if dentists added bleaching trays to laser whitening in certain situations.

Pros and Cons

Teeth Bleaching 

The simplest method for a dentist to whiten your teeth is bleaching. Although you get the same outcome from both approaches, it is best to consider other factors before choosing the procedure that best works for you. Consider these advantages and disadvantages before making any decision.

Pros:

Cost-Effective: Custom-fit bleaching trays are typically less expensive (around $500) and can be reused for maintenance treatments, which are much cheaper over time.

Gradual Results: While results take longer to achieve (often requiring several applications over weeks), this method allows for more control over the whitening process and can be less harsh on sensitive teeth.

Convenience at Home: Patients can use bleaching trays and home teeth whitening kits at their convenience without needing frequent dental visits.

Cons:

Longer Treatment Time: Achieving desired results takes longer compared to laser whitening, which may be a drawback for those seeking quick fixes.

Potential Discomfort: Some users find wearing trays uncomfortable or may not tolerate the prolonged exposure to the bleaching agent well.

Less Immediate Impact: Initial results are not as dramatic as those seen with laser treatments, which may discourage some users

Laser Teeth Whitening

Pros:

Quick Results: Laser teeth whitening can typically be completed in a single session lasting 15 to 60 minutes, providing immediate and noticeable results.

Enhanced Efficacy: The use of lasers intensifies the action of the whitening agent (usually hydrogen peroxide), leading to more effective stain removal compared to traditional methods.

Professional Supervision: The procedure is performed by dental professionals, ensuring safety and the ability to tailor treatments to individual needs.

Minimized Sensitivity: Some studies suggest that laser treatments may cause less sensitivity than other whitening methods, although this can vary by individual.

Cons:

High Cost: Laser whitening is generally more expensive, often costing around $1,000 per session, making it less accessible for some patients.

Temporary Sensitivity: While sensitivity may be lower, some patients still report discomfort after treatment.

Not Suitable for All Stains: This method may not effectively treat certain types of stains, such as those caused by trauma or medications.

After getting your teeth whitened, make sure to watch what you eat as it will have a direct impact on your oral health. Follow your dentist’s advice to avoid discomfort and you needing to undergo the procedure all over again. 

Effectiveness Comparisons

Research indicates that laser-assisted bleaching can significantly outperform traditional power bleaching techniques. A study found that laser whitening resulted in a greater reduction in yellowness and an increase in whiteness compared to conventional methods2. The speed of laser whitening not only enhances patient comfort but also increases cooperation during treatment due to shorter appointment times.

Longevity of Results

Both methods can provide long-lasting results; however, laser teeth whitening tends to have a slight edge in longevity due to its ability to penetrate deeper stains effectively. Patients who maintain good oral hygiene and avoid staining foods and beverages can expect their results to last longer regardless of the method chosen34.

Conclusion

Choosing between laser teeth whitening and traditional bleaching largely depends on individual needs, budget, and time constraints. For those seeking immediate results with minimal discomfort, laser whitening may be the ideal choice despite its higher cost. Conversely, individuals looking for more budget-friendly options may find success with traditional bleaching methods.

Ultimately, consulting with a dental professional will help determine the best approach tailored to specific dental conditions and aesthetic goals. Whether opting for laser treatment or traditional bleaching, achieving a brighter smile is within reach through these effective dental procedure.
