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

What is Teeth Whitening?

As we age, our teeth become more susceptible to staining due to food and other substances we consume. Products such as tobacco, tea, wine, coffee and even berries are notorious for staining teeth.

Today, more people are choosing in-office and at-home teeth whitening procedures to reverse the effects of stains and aging. 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 for 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 are expected to last.

In-Office Teeth Whitening

Though in-office teeth whitening has an immediate whitening effect on your smile due to a high concentration bleaching gel, it will not permanently whiten your teeth.

Because a dentist is performing your in-office teeth whitening treatment, it’s 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.

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.

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.

Several 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.
