How Long Does Teeth Whitening Take?

5 Nov 2020 by  admin in Whitening

The general rule is that with in-office teeth whitening, after an hour or so of treatment, you can expect to go home with noticeably whiter teeth. The powerful formula in at-home whitening trays from your dentist will likely show great results within about 10 days of daily use. Over-the-counter whiteners may take weeks or months to achieve a noticeable effect, and the results are often disappointing.

Everyone wants a brighter, whiter smile. If your smile is dull or your teeth off-color, teeth whitening can make a huge difference in your appearance and confidence. How long it takes to achieve teeth whitening depends upon the type of procedure. The teeth’s condition and reason for discoloration also come into play.

When it comes to perfecting your smile, do not waste your time and money with over-the-counter products. Not only can these products take weeks to work – after a lot of time and effort – but the product may not prove right for your needs.

Always have a professional consultation before embarking on a cosmetic procedure such as teeth whitening. The dentist makes an assessment and lets you know which treatment is most suitable for your mouth.

In-Office Teeth Whitening

For fast results, nothing beats in-office teeth whitening with technology that relies on light and heat. The whole process takes less than an hour, after which most patients’ teeth will appear at least three shades lighter.

Some patients may need a follow-up treatment. Those with badly discolored teeth may need additional visits.

Patients leave the office with whitening gel for ongoing tooth maintenance.

At-Home Whitening

Patients on the go may prefer an at-home whitening kit. Do not confuse these professional whitening kits with the ones available over-the-counter. Not only are professional whitening kits more effective, but they will not irritate the mouth the way some store-bought products do.

These whitening trays are custom-tailored for your smile. Once home, use these trays for just 30 minutes daily for 10 days to achieve a significantly whiter smile.

The advantage of at-home whitening kits is that you can use them at your convenience. If the half-hour required for the daily process is only available late at night, that is fine. Whiten your teeth on your own schedule.


Keep in mind that teeth whitening only works on natural teeth. If you have a crown or veneer, ask the dentist about methods to lighten any staining.

Long-Term Effects

No matter which tooth whitening method you choose, the results should last between two and three years. You can extend the period before another tooth whitening session by avoiding food and drink that stain the teeth. The same holds true for smoking, which can cause serious tooth discoloration along with health problems.
