How long does teeth whitening actually last?

Posted in Cosmetic Services

If you're thinking of getting your teeth professionally whitened, you might be wondering how long it will last. At All Smiles Dental Centre we offer both in-office and at-home teeth whitening options and our dentists are here to tell you the effectiveness of both treatments.

What is teeth whitening?

While we age, our teeth become more vulnerable to stains because of the food we eat and other substances we consume. Food particles are naturally attracted to our tooth enamel, and substances such as wine, coffee, tea, tobacco, and even berries lead to stains.

Today, more people are choosing in-office and at-home teeth whitening procedures to reverse the effects of stains and aging. Professional teeth whitening can help to improve your confidence in your smile.

In this post, we explore how long the effects of teeth whitening may last, and what you can do to ensure your teeth remain white as long as possible after treatment.

How long will the effects of teeth whitening last?

Depending on whether you choose in-office teeth whitening or the at-home alternative, you'll want to keep in mind how long each is expected to last.

In-Office Teeth Whitening

Though in-office teeth whitening has an immediate whitening effect on your smile due to a more powerful and highly concentrated bleaching gel, it will not permanently whiten your teeth.

Because a dentist is performing your in-office teeth whitening treatment, it’s safe, reliable, and non-invasive. Dentists screen teeth whitening patients to ensure their oral health doesn’t preclude them from being a candidate for the treatment.

However, after a time you’ll need to return for more teeth whitening treatments. If you continually expose your teeth to foods or drinks that may cause them to stain, the whiteness of your teeth will likely begin to fade after a few months.

Provided you avoid these foods and drinks following your treatment, you may only require a touchup after about a year.

At-Home Teeth Whitening

Using take-home teeth whitening products from your dentist’s office can help to refresh the effects of professional teeth whitening treatments - and you can do them in the comfort of your own home.

Most patients notice a difference within 10 to 14 days of starting to use their at-home teeth whitening kit. The full results usually appear by the end of the treatment period, and they tend to last significantly longer than teeth whitening treatments purchased from the store.

The results seen from at-home teeth whitening kits can last anywhere from a few weeks to a few months depending on the treatment, its strength, how diligent you are about reapplying the gel, and other factors.

Of course, ensure you attend your regularly scheduled dental appointments, and that you maintain an excellent at-home oral health routine (including brushing and flossing daily).

A number of factors can influence how white your teeth look - and remain - after a teeth whitening treatment. The degree of whiteness varies from person to person depending on the:

  • Level of staining before the teeth whitening procedure
  • Condition of your teeth
  • Type and strength of whitening treatment used

If you are curious about your teeth whitening options and which ones might work for you, speak with your dentist. You might also want to consider looking up teeth whitening reviews online to learn about other patients’ experiences.
