How Long Does Teeth Whitening Last?

May 15, 2024

Teeth-whitening outcomes might vary based on lifestyle and dental hygiene. Your results may fade sooner if you drink a lot of coffee or smoke.

However, if you brush regularly and limit the consumption of staining foods, the effects can last longer. Keep reading to find out how long does teeth whitening last and how you can keep your teeth bright for an extended period of time.

How Does Teeth Staining Happen?

If you’re curious about how staining occurs and why you should consider teeth whitening, here’s what you need to know: over time, your teeth absorb stains from many causes, becoming yellow, brown, or even orange.

Staining can be classified into two types: intrinsic, which affects the interior of the enamel, and extrinsic, which affects the exterior layer. Food, beverages, or smoke produce extrinsic stains, but intrinsic stains require in-office treatments.

How Long Does It Take to Whiten Teeth?

The effectiveness of teeth whitening relies on the method you use.

In-chair whitening, performed at a dental clinic, uses powerful whitening solutions to provide significant results in about 1-2 hours.

At-home whitening kits use custom mouth trays with a lower-concentration whitening agent, taking about 2-3 weeks for results.

How Long Does It Last?

No matter which teeth whitening method you go for, the results will eventually fade. However, some treatments may last up to 2 or 3 years.

Popular whitening methods include:

Whitening Toothpaste and Mouthwash

Whitening toothpaste and mouthwash are easily available at most pharmacies. They often use hydrogen peroxide and mild abrasives to whiten teeth, but it can take up to 6 weeks to see results.

The whitening effect usually lasts 3-4 months. However, since these products contain abrasive chemicals, they might be harsh, so we don’t advocate using them as your primary whitening technique.

Whitening Strips

Whitening strips are famous OTC products that use peroxide to remove stains from your teeth. Some come with LED lights to speed up the process. However, results can take a few weeks to appear and often last up to 6 months.

One study suggests that overuse may even damage dentin.

Whitening Gel Trays

Whitening gel trays provide longer-lasting results than over-the-counter solutions. After taking dental impressions, a custom tray is created. You fill the tray with peroxide gel and wear it for anything from a few hours to a few days, depending on the prescribed strength. This procedure allows for more tailored and effective tooth whitening.

Final Word

Remember, tooth whitening treatments remove stains, but they don’t prevent them from coming back forever. If you maintain good oral hygiene, professional dental treatments can help preserve the brightness of your smile.
