However, given the up-front investment of whitening treatment compared to store-bought options, many wonder how long teeth whitening results will last.
The more you know, the better you can help your smile stay white. Learn more about how long whitening results last and what you can do to extend them.

Longevity of Teeth Whitening Services
There’s no hard and fast rule for how long your teeth stay white. In general, patients notice a clear difference for 6 months up to 2 years.
Why such a range?
Several factors will affect the longevity of your results, including:
- The type of whitening treatment
- Consuming dark-colored drinks and food (tea, coffee, tomato sauce, berries, soda)
- Dental hygiene efficacy
- Whether or not you use a straw when drinking (doing this helps prevent stains)
- If you rinse your mouth after eating (doing this helps prevent stains)
- Underlying medical conditions
- Certain medications
In-Office vs Take-Home Whitening Results
In-office whitening is applied by the dentist, giving you immediate results in one visit. Take-home kits still use quality material, but are done gradually on your own. On average, in-office results last longer because the bleaching agent is more concentrated.
However, we often recommend the take-home kits to help maintain the results from your in-office whitening. By using those kits, you may extend results for 6-12 months.
Do I Need a Whitening Touch-Up?
In reality, most patients will want a touch-up treatment down the line. However, it’s important not to over-whiten your teeth. Our dental team will help you decide when a touch-up is beneficial and safe for your smile. If you notice your teeth looking less radiant or collecting stains, then it may be time for a follow-up.
Get a Radiant Smile
Professional teeth whitening can last a long time, especially if you take steps to reduce staining. However, it’s not a permanent solution, and touch-ups can help you keep your smile looking great.
