Some participants in the clinical trial saw results in as little as two days. Full results will take longer depending on the type of teeth staining you have. In a clinical trial, after just three weeks of use, the pen whitened teeth an average of five shades, with some participants seeing up to 10 shades of whitening.

Advanced Teeth Whitening Pen dispenses a whitening gel to the brush tip, which is then applied directly to the teeth surfaces. How often can I use the Smileactives® Advanced Teeth Whitening Pen? Up to 4 times daily, depending on the severity of tooth staining.

This product does NOT make your teeth whiter with continued use! It only cancels out yellow tones temporarily to make your smile look better for a few hours when you are out. That is it! So you're wasting your time and product using it everyday thinking you're whitening your teeth.

As a general rule, it is recommended to leave whitening gel on your teeth for 30 minutes to 1 hour for first time users and increase the wearing time if there is little or no tooth sensitivity. If your teeth are stained or very yellow, it will take longer to bleach them.

1-3 years The results of dental chairside or in-office bleaching are long-lasting but not permanent. With proper care, your brighter smile can last for 1-3 years. A single session may last anywhere between 40 minutes to an hour.

Hydrogen peroxide is an inexpensive household product you probably have on hand right now. When used carefully, it can be an effective way to whiten your teeth. But if used incorrectly - in concentrations that are too high or if used too often - it can cause serious and sometimes expensive tooth damage.

There are a number of ways that you can whiten your teeth if they are or have already yellowed; these are a mix of over-the-counter toothpastes, home whitening products or, in some cases, mechanical plaque removal by a dentist or hygienist.

With a super-high concentration hydrogen peroxide, a professional bleaching treatment is undoubtedly going to yield the most effective whitening results. "If you get a good result from over-the-counter products then you should get even better results from in-office, professional whitening," points out Dr. Lowenberg.
