## Product: Crest 3D Whitestrips Professional Effects
**Brand:** Crest

Using Crest 3D Whitestrips Professional Effects is pretty simple and doesn't need any extra gadgets like [LED lights](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DLED%2Blights%26tag%3Dssw.ans.tx-1-20) to get good results. Here's a quick guide to help you out, based on what we've found and the manufacturer's advice:

1. **Get Ready**: Start by making sure your teeth are clean and dry. This really helps the strips stick better.

2. **Apply the Strips**: Peel the strip off its backing. You'll find two strips in each pack—one longer one for your upper teeth and a shorter one for the lower. Line it up with your gum line and press it onto your teeth. Fold any extra part behind your teeth to keep it snug.

3. **Timing**: Usually, you wear them for about 30 minutes each session. If you're comfortable with it, you can leave them on for up to an hour, as some people do to try for even better results.

4. **Take Them Off**: Peel off the strips carefully once you're done. Give your teeth a gentle brush to get rid of any leftover gel.

These strips use something called Advanced Seal Technology, which keeps them in place, so you can chat or sip some water without them moving around.

According to the manufacturer's description, they use the same kind of hydrogen peroxide that's in professional treatments, aiming to give you up to 20 levels whiter teeth over a 22-day period. So, they're a handy at-home option for sprucing up your smile.

Our research shows that plenty of people notice their teeth getting brighter just by sticking to it, without needing an [LED light](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DLED%2Blight%26tag%3Dssw.ans.tx-1-20). 

While Crest does have other kits with LED lights, these strips are meant to work well on their own. 

For the best outcome, try to use the strips daily. If you notice any sensitivity or discomfort, maybe cut back on how often you use them or talk to a dental pro if you're worried about your teeth's sensitivity or general oral health before diving into any whitening treatment.

If you follow these steps, you should be on your way to a whiter smile right at home. Good luck with your whitening!
