Are you thinking of whitening your teeth? Maybe you’re wondering where to begin. There are many whitening options out there, from relatively inexpensive over the counter whitening solutions including strips and gels to more expensive in-office treatments. Here, we’ll talk about whitening strips and why you may or may not want to give them a try.


Teeth whitening strips do work. Will they make your teeth really white though? It all depends on the origin of your stains and your teeth’s natural color. Strips can remove lifestyle stains. These are things like drinking coffee or red wine and smoking. However, they won’t remove stains occurring from health issues or reactions to medications. If you use the strips as directed, you should see results in about 7 days. There are more advanced whitening strips claiming results as early as three days. Once you complete a full cycle, results can last up to six months. To help your teeth stay whiter longer, avoid foods and drinks that stain teeth. Also, brush with whitening toothpaste.


Regular strength teeth whitening strips range from $15 - $30 for a one-week treatment kit. You can purchase them just about anywhere toothpaste is sold. You may also check with your dental office to see if they sell professional strips. These strips contain stronger, whitening ingredients. They may be a little more expensive than those sold in stores. Strips are a very affordable and great way to try whitening your teeth, especially if you’re considering other in-office whitening treatment options (such as lasers), which can be much more expensive.

Ease of Use

Whitening strips are so easy to use. The most difficult part may be remembering to use them. They come with an upper and lower row strip. You place them on your front teeth and wear them for 30 minutes or as instructed.

Side Effects

With prolonged use, teeth whitening can cause teeth sensitivity. Teeth whitening is considered safe for adults. Children and pregnant women should consult their doctor before use.

If you want to brighten up your smile, whitening strips may be ideal for you. They are easy to use, affordable, and work on removing surface stains. Talk to your dental professional for their opinion. Remember, good oral hygiene at home and routine professional cleanings make whiter teeth as well.
