Unfortunately, dental staining is a part of life. Even if you’re the best brusher and flosser on the planet, daily meals will eventually turn your pearly whites yellow. It’s no wonder why teeth whitening treatments are one of the most popular dental cosmetic procedures!

Depending on your smile, your dentist could eliminate dental staining in just one appointment – or over the course of a few weeks. To get an idea of how many whitening treatments it takes to brighten your teeth, keep reading.

The In-Office Whitening Process

If you’d prefer a lightning-fast treatment that only takes one appointment, then the in-office whitening process will appeal to you most. Your dentist will be able to control the entire process, right down to the specific dosage of the bleaching agents, so this is also a great option for those with overly sensitive teeth. Applying the whitening gel and letting it cure takes just one hour for most patients.

Whitening Your Teeth from Home

Let’s say you have a hectic schedule, and trying to find time to go to the dentist for even an hour is a headache. There’s another, more cozy option: whitening your teeth from home. Your dentist will provide you with a customized set of trays and detailed instructions for applying the gel every day.

Since you’ll be the one controlling it, the gel formula won’t be as strong as the in-office version, and it will take about two weeks to achieve a brighter smile. But you will be able to relax in your favorite chair while perfecting your teeth, which is definitely a luxury!

Factors That Could Affect Your Treatment Plan

In addition to these timeline averages, there are factors that could impact your treatment plan – and the number of times you need to whiten your teeth.

If you have severe staining, for example, it might take two-to-three in-office treatments to achieve the results you want, or a couple more weeks of at-home application. It’s also not recommended to whiten your smile if you have an active case of cavities, so you may need to take steps to restore your oral health before enhancing your aesthetics.

Conclusion

Overall, teeth whitening is a quick process when overseen by a qualified dental professional. Your treatment timeline may take longer (or shorter) than average depending on your unique situation, but you can count on your dentist to give you a reliable estimate during your consultation. Give them a call today if you’d like to know how long it might take to brighten your smile!
