How Long Does Teeth Whitening Last?

How long your teeth whitening results last will depend upon the type of bleaching product you are using. Since there is a wide range of whitening options, the average teeth bleaching results from in-office treatment can last from six months to three years. The average results for consumers for teeth whitening may last for about one year.

The length of time you can expect from your tooth whitening treatment to last is based upon the type of whitener you’re using as well as your lifestyle habits. 

Tooth whitening treatments are designed to reduce stains. If you have good oral habits, do not smoke cigarettes, avoid certain drinks, keep your teeth clean, at-home products and professional teeth whitening procedures will last longer. 

Here are some of the most popular teeth whitening treatments and how long they last.

In-office tooth whitening

Professional in-office teeth whitening treatment should provide long-lasting results for 1 to 3 years. This procedure is done in your dentist’s office, and it usually requires only one visit. 

Popular products such as Zoom! Whitening uses strong bleaching agents, such as highly-concentrated 25% Hydrogen Peroxide and Ultradent Opalescence Boost PF 40% Hydrogen Peroxide. This procedure also uses Heat and light to accelerate the bleaching process further.

Whitening toothpaste 

Using whitening toothpaste twice daily may take anywhere from 2 to 6 weeks before you see any results. Consumers report these results can last for up to 3 or 4 months from a whitening toothpaste. 

Whitening mouthwash

Using whitening mouthwash may take up to 3 months before you see any results. Whitening mouthwashes usually contain hydrogen peroxide and can be used daily to help remove some surface stains from your teeth.

It is recommended to use with other treatments, such as in-office whitening or whitening strips. When used alone, its effects are not as effective or long-lasting.

Whitening strips

On average, some whitening strips may last for up to 6 months.

Whitening strips are considered one of the most effective over-the-counter treatments for whitening teeth at home. 

The main ingredient in teeth whitening strips is peroxide to bleach and remove stains. 

Some of the high-quality consumer brands of whitening strips may remove both extrinsic and mild intrinsic teeth stains.

At-home whitening gel trays

The average time from a whitening gel tray to start seeing results is about a week. When used in combination with proper oral hygiene and dentist-supervised treatment, whitening gel trays should give you long lasting results for one year or longer.

teeth with whitening tray

Your dentist will provide a custom-made tray that you fill with a gel whitener at home. This gel whitener supplied by your dentist is stronger than the type used in over-the-counter consumer products.

Diet tips for whiter teeth

Depending on what you eat and drink daily may stain your teeth. Some common foods and drinks that stain your teeth are:

  • coffee
  • tea
  • red wine
  • grape juice
  • cola

If you consume these regularly, make sure to brush, floss, and often rinse after eating and drinking.


At-home treatments such as whitening toothpaste, mouthwashes, and pens do not last very long.

White strips are the most effective over-the-counter whitening treatment you can use without a dentist’s supervision.

At-home gel trays that are customized to fit your mouth provided by your dentist offer the longest-lasting teeth whitening.
