How long does teeth whitening last?

Teeth whitening is a popular cosmetic dental procedure that can help you achieve a brighter, healthier-looking smile. Depending on the type of product used, the individual's lifestyle habits, and whether the treatment is done correctly, the results of a tooth whitening treatment can last up to three years. Discover the different methods of tooth whitening and find out how they should be done correctly so that your treatment lasts as long as possible.

Methods of Teeth Whitening

The most popular techniques for teeth whitening and their anticipated results are:

  • Teeth whitening toothpaste (short-term surface stain removal only)
  • Over-the counter whitening strips (six months to two years if done correctly)
  • Teeth whitening trays (up to one year)
  • In-office laser whitening (up to three years)

Whitening Toothpaste

Whitening toothpaste is one of the most common at-home methods, but it typically takes two to six weeks before any noticeable results can be seen. It may be a convenient and cost-effective solution for some, but it is pertinent to consider its drawbacks when looking for a reliable way to whiten your teeth.

For example, if you forget to brush your teeth twice a day for two minutes each time, the results won’t be very significant. Furthermore, whitening toothpaste can cause tooth sensitivity or gum irritation due to its abrasive nature.

How Long Do the Effects Last?

Whitening toothpaste may help to get rid of surface stains, but it can only penetrate so far. If the stain is deeper, the only option is professional whitening. Overall, using whitening toothpaste to whiten your teeth is not a very effective method. Unfortunately, the approach is unlikely to produce any lasting effects at all.

Although it may be able to remove surface stains, whitening toothpaste won't alter the natural shade of your teeth.

Over-The-Counter Whitening Strips

Over-the-counter whitening strips are a popular and convenient method of teeth whitening. While they may not be as effective as professional teeth whitening treatments, they can still help to lighten teeth by one or two shades.

The secret is to apply hydrogen peroxide or carbamide peroxide to the teeth for the proper amount of time and concentration. Crest Whitestrips are a well-known brand of over-the-counter whitening strips that contain hydrogen peroxide. Effective results can be obtained by wearing them for 30 minutes a day for 14 days.

When used correctly, over-the-counter whitening strips can last anywhere from six months to two years. It's critical to note that using them for too long or taking them off too soon can lead to side effects such as tooth sensitivity and gum irritation.

Teeth Whitening Trays

At-home whitening kits can also be effective, but they take more time to show results. Usually, these mouth trays are made by your dentist to precisely fit your mouth and contain a lower concentration of the whitening agent.

Wear them daily for short periods of time, and in some cases, many hours or overnight, every day, for a week or more.

When combined with proper oral hygiene, at-home kits should give you long-lasting results lasting up to one year.

The success of the whitening process greatly depends on the technique and whether it is applied correctly.

In-Office Laser Whitening

For long-lasting results, it is suggested to visit your dentist for a chairside or in-office procedure. These treatments use highly concentrated hydrogen peroxide or carbamide peroxide, combined with heat or light, to achieve significant whitening results in just one to two hours.

In-office laser whitening has more reliable and long-lasting effects than other whitening methods because it offers several advantages over at-home whitening treatments. These advantages include:

1. Produces instant results: Unlike at-home teeth whitening, this technique results in noticeably whiter teeth when you step outside.

2. Is safer: Laser teeth whitening is performed under the supervision of a dental professional and is done in a single session. This eliminates the potential for misuse or overuse of products.

3. It is convenient: The procedure takes between 15 and 60 minutes.

4. It uses more powerful chemicals: This procedure typically uses stronger chemicals than those available in at-home whitening treatments. As a result, laser teeth whitening is more effective and yields faster results than home treatments like daily whitening strips or whitening toothpaste.

5. Minimizes adverse effects on tooth structures: Power bleaching aims to effectively whiten teeth while minimizing any negative effects on tooth structures.

6. Improves the success of overall tooth whitening: The activation of the bleaching agent using a variety of light sources and laser systems can enhance the success of overall tooth whitening.

7. Increased chance of reducing tooth and gingival sensitivity: Bleaching with a diode laser can have the additional advantage of reducing tooth and gingival sensitivity.

8. Quicker and greater whitening effect on demineralized teeth: The increased concentration of hydrogen peroxide employed in power bleaching could help to achieve a quicker and greater whitening effect on demineralized teeth compared to that which occurs with the home bleaching process.

When done correctly, in-office laser bleaching can produce long-lasting results for up to three years.

The Bottom Line

If carried out properly, in-office laser whitening can produce the most effective results, potentially lasting up to three years in some people. You can help the whitening last as long as possible by maintaining proper oral hygiene and avoiding foods and beverages that can stain teeth. These include red wine, coffee, tea, and beets. Brushing your teeth twice a day can also help keep your results looking their finest.
