Colgate Teeth Whitening Review

Ingredients

Colgate's teeth whitening kits include 9% hydrogen peroxide serum. Hydrogen peroxide is the most common compound for whitening teeth and it's known to be safe and effective. You don't see that many whitening kits with 9% hydrogen peroxide serums outside of a dentist's office, so the Colgate teeth whitening kit is a good choice for those who want to see results quickly. The company is transparent about its ingredients, which isn't true of all teeth whitening services, so you can feel confident that you're dealing with a safe, quality product. The Oh So Dazzling serum that's part of Colgate's SuperNova system is 100% vegan, sugar-free, and gluten-free.

The SuperNova kit also includes an LED whitening device with its charging cord and a case. This is designed to speed up the whitening process when used for a few minutes after applying the serum. You see this in many teeth whitening kits these days and, while some question whether they actually help whiten your teeth faster, there is no harm in using them.

Colgate also manufactures a wide range of other teeth whitening products available for purchase separately, including whitening rinses, toothpaste, and pens.

Effectiveness

Your teeth could whiten by six or more shades after using this teeth whitening kit, according to Colgate's website, but actual results will probably depend on how white your teeth were to begin with. Most of its customers appear satisfied with the results they achieved with the whitening kit, saying that it's simple and easy to use. A few users even reported noticeable results within a day or two of using the product.

While Colgate states that its whitening system is designed to create no tooth sensitivity, most whitening solutions are capable of irritating your gums and causing temporary sensitivity. You can minimize this by following directions carefully and, if necessary, spacing out your treatments. You can also purchase a desensitizing gel to use on your teeth with the whitening serum. Colgate does not offer its own desensitizing gel, but you can find some elsewhere online.

Ease of Use

Users report that the whitening kit is simple to use. All you have to do is put some serum in the one-piece LED mouth tray, insert it into your mouth and wait ten minutes. Colgate recommends that you not rinse or eat or drink anything for 4 hours post-treatment. Each kit includes a 30-day supply of whitening serum.

Colgate recommends you use the system for ten minutes per day for ten days in a row. This is a pretty short wear time, so the Colgate teeth whitening kit is a good fit for those who don't have a half-hour to sit around whitening their teeth. It's best to give your mouth a few days' rest in between ten-day treatments. Then if you still want your teeth to be whiter, you can purchase serum refills from Colgate and continue whitening. Like most off-the-shelf products, Colgate's whitening trays are one-size-fits-all. 

Price

Colgate's SuperNova teeth whitening kit is not the cheapest one around, but it is less expensive than having custom trays built by a dentist. Those who cannot afford to pay the full cost of the kit at once can pay in four installments instead. You can also save by signing up for a subscription. If you choose to do this, Colgate will send you serum refills automatically every three months until you unsubscribe.

The refills are also a little pricier than average, but you have to remember that you're getting a stronger whitening gel than many other teeth whitening kits offer. A single 10-day supply of Colgate's serum will probably go further than some competitors' gels would. You can purchase gels in five- or 10-day supplies and you again have the option to make a one-time purchase or subscribe for discounts on future gel purchases.

Colgate offers a two-year warranty on the LED whitening device and a 30-day money-back guarantee if you're not satisfied with your results. Also, shipping is free on every order.
