Are At Home Teeth Whitening Kits Effective?

Table of Contents

Are you looking for a brighter, more radiant smile? Many people turn to at-home teeth whitening kits for a convenient and affordable solution. But are these kits really effective? In this article by Novudentics, we’ll explore the world of at-home teeth whitening and compare it to professional laser whitening treatments that many people come to us for.

What Are At-Home Teeth Whitening Kits?

At-home teeth whitening kits are popular products that promise to remove stains and discoloration from your teeth in the comfort of your own home. These kits typically include whitening strips, gels, or trays that you apply to your teeth for a specified period of time.

Some popular at-home whitening kits you may find in stores include:

  • Crest 3D White Strips
  • Colgate Optic White Advanced LED Whitening
  • Opalescence Go Whitening Trays
  • AuraGlow Teeth Whitening Kit

How Do At-Home Teeth Whitening Kits Work?

Most at-home whitening kits use peroxide-based bleaching agents, such as carbamide peroxide or hydrogen peroxide, to break down and remove stains on your teeth. These agents work by penetrating the enamel and oxidizing the discolored molecules, resulting in a whiter appearance, although minor. The difference isn’t going to be mind-blowing.

Are At-Home Teeth Whitening Kits Effective?

While at-home teeth whitening kits can provide some level of whitening, their effectiveness is limited compared to professional treatments. At-home kits typically contain lower concentrations of bleaching agents, which means they may take longer to produce visible results and may not be as effective on deep-set stains.

Additionally, at-home kits may not evenly whiten your teeth, leading to inconsistent results. Improper use of these kits can also cause temporary tooth sensitivity or gum irritation.

How Long Does Teeth Whitening Last?

The longevity of teeth whitening results depends on various factors, including the type of treatment, your lifestyle habits, and your oral hygiene routine. At-home whitening kits typically provide results that last for a few months, with touch-ups required to maintain the whiter appearance.

In contrast, professional laser teeth whitening can produce results that last up to a year or more with proper care. To extend the longevity of your whitening results, it’s essential to maintain good oral hygiene, avoid consuming stain-causing foods and beverages, and schedule regular dental check-ups and cleanings.

Laser Teeth Whitening vs. At-Home Kits

For those seeking a more dramatic and long-lasting whitening effect, laser teeth whitening is a far superior option compared to at-home kits. Laser whitening, also known as power whitening or in-office whitening, is a professional treatment performed by a dentist or prosthodontist.


During a laser whitening treatment, a high-concentration peroxide gel is applied to your teeth and activated by a special light or laser. This process accelerates the whitening process, allowing for faster and more impressive results in just one session.

Some key benefits of laser teeth whitening over at-home kits include:

  • Faster results: Laser whitening can whiten your teeth by several shades in just one hour-long appointment.
  • More effective: The higher concentration of bleaching agents used in laser whitening can tackle even the most stubborn stains.
  • Even whitening: A professional can ensure that the whitening gel is evenly applied to your teeth for consistent results.
  • Reduced sensitivity: Dentists can take precautions to minimize tooth sensitivity during and after the treatment.


While at-home teeth whitening kits may offer some improvement in the appearance of your smile, they are not as effective as professional laser whitening treatments. If you’re looking for a significant and long-lasting whitening effect, it’s best to consult with us here at Novudentics about laser teeth whitening options.
