How Long Does Teeth Whitening Last, and Is It Safe?

Teeth whitening results vary depending on the method used, lifestyle habits, and how well you care for your teeth after treatment. On average, professional teeth whitening can last between six months to three years, with most patients enjoying noticeable results for about one year before needing a touch-up. At-home whitening kits typically provide shorter-lasting effects compared to in-office treatments, but regular maintenance can help extend the brightness of your smile.

Several factors can impact how long your whitening results last, including:

  • Diet: Consuming coffee, tea, red wine, and dark-coloured foods can cause staining over time.
  • Oral Hygiene: Brushing twice a day, flossing, and using a whitening toothpaste can help maintain results.
  • Smoking & Tobacco Use: Nicotine and tar can quickly lead to yellowing and stains.
  • Type of Whitening Treatment: In-office whitening treatments tend to last longer than over-the-counter options.

Is Teeth Whitening Safe?

Teeth whitening is safe when done correctly, especially under the supervision of a Kanata dentist. Professional whitening treatments use safe, controlled levels of whitening agents like hydrogen peroxide or carbamide peroxide, which effectively break down stains without damaging your enamel.

Some patients may experience temporary tooth sensitivity or mild gum irritation after whitening, but these effects typically subside within a few days. If you have sensitive teeth, your dentist may recommend a lower-concentration whitening treatment or suggest desensitizing toothpaste before and after your whitening session.
