Do the teeth whitening kits featured on Groupon really work?


I keep seeing Groupons for teeth whitening kits. $39 is much cheaper than having my teeth whitened by my dentist. But do these kits really work? Thanks! Chantele R.

Chantele – Whether or not the teeth whitening kit works depends on the agent used in the whitening gel, as well as the strength of the whitening agent. But there are several reasons that you might want to have your teeth professionally whitened by your dentist.

Over-the-counter whitening strips and gels will only remove surface stains, if they help at all. The same is true for whitening toothpaste. The whitening gel that you receive from your dentist will penetrate your teeth and remove embedded stains.

Teeth bleaching  isn’t right for everyone. Depending on the cause of the stains, whitening your teeth will make the stains even more noticeable. Your dentist will exam your teeth, determine the cause of the stains, and recommend the appropriate treatment for them—which may not be teeth bleaching. In some cases, porcelain veneers are the only way to conceal stains or discoloration in teeth.

Your dentist will take an impression of your teeth so that customized teeth bleaching trays can be made for you. Ready-to-use kits have one-size-fits-all trays, which often do not fit correctly. The results of the whitening gel will not be as efficient as it would with customized trays. If the ready-made trays are too large, gel will likely be wasted.

Talk with your dentist about your interest in teeth whitening. He or she will be able to give you a beautifully white smile. Some dentists offer teeth whitening specials from time to time, too.
