How long does teeth whitening actually last?

Are you considering teeth whitening treatment and wondering how long the effects will last? Our Calgary dentists explain in-office and at-home whitening options and the factors that determine how white your smile will remain, for how long.

How Teeth Whitening Works

Our teeth become more susceptible to staining due to food and other substances we consume as we age. Our tooth enamel naturally attracts food particles, and products such as tobacco, tea, wine, coffee and even berries are notorious for staining teeth.

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

Below, 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 The Effects of Teeth Whitening Last

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

The In-Office Teeth Whitening Process

Although in-office teeth whitening has an immediate whitening effect on your smile due to the high concentration bleaching gel used, this process does not permanently whiten your teeth.

Since a dental professional will be performing your in-office teeth whitening treatment, the process is considered 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 subsequent 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.

The At-Home Teeth Whitening Process

Using take-home teeth whitening products from your dentist’s office can help to fresh 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 gleaned 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:

  • Condition of your teeth
  • Level of staining before the teeth whitening procedure
  • 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.
