This product needs to be recharged at least once a week with regular use, yet it doesn't give a low-battery warning.

But, generally speaking, if you apply the solution regularly for a specified period of time, you’ll likely notice a difference after two weeks.

While the results and lack of irritation from the gel were huge sells to us, we also really appreciated the fact this particular kit focuses on enamel care, containing aloe vera, calcium and vitamin E, to care for your teeth. Light emitting diode (LED) is a type of light that works to activate teeth-whitening agents – gels, for example – and is said to make them work faster.

While you’ll still need to use the device for 20 minute a day, this time is split into two sessions (one in the morning, one in the evening). The peroxide-free teeth whitening strips by DrDent are formulated by dentists and made with a PAP (Phthalimide Peroxy Caproic Acid) formula to protect your teeth.Our teeth whitening strips are infused with the natural flavours of coconut and mint oil for a more soothing and fresh tasting teeth whitening experience. I could see a small difference which has given me the desire to continue until I achieve my desired goal. We did find that using the strips for less than an hour helped a little, while still delivering a dazzling smile.

The peroxide available in pens is often lower than in a gel kit, and their lower duration makes them less effective than at-home treatments, but their effectiveness is sacrificed for their ease of use on the go.Doesn’t taste horrible or leave a taste in your mouth, when they’re on you don’t even know they’re there!

My teeth are normally extremely sensitive to whitening products, but I've found no sensitivity whilst using Dr Dent. Don’t leave the solution, be that gel or strips, on longer than the brand advises, as this may irritate gums.Velayo adds that while a peroxide-based treatment is your best bet for a long-lasting treatment, how well the product works will come down to the concentration of the peroxide, how long you use it, and how it's applied.
