How Does Teeth Whitening Work?

How Does Teeth Whitening Work?Maybe you have a big job interview coming up? A graduation? Or pictures at the wedding that will be the “happily ever after” for you and the love of your life? Maybe you just want to look and feel your best? If so, professional teeth whitening treatments might be the key to transforming your smile and letting you shine!

As our teeth age, a lifetime of use can cause discoloration. This natural discoloration can be exacerbated by other factors such as smoking, tobacco use or regular consumption of coffee, tea, cola or red wine. Although daily brushing and flossing can help slow this discoloration and keep your smile healthy, these alone cannot reverse this discoloration. Over-the-counter whitening strips and specialty toothpastes may help some but are limited in strength and effectiveness.

This is where professional teeth whitening treatments come to your rescue! These fast and affordable treatments are performed in the office by your dentist and can produce dramatic results. Dr. Gotwalt offers painless but effective treatments that can brighten your smile by several shades in just one session. Some treatments are available that can even be done in the comfort of your own home!

Dr. Gotwalt of Lititz PA offers two popular, proven methods of teeth whitening:  KöR Whitening and Opalescence Teeth Whitening.

KöR Whitening is available as an in-office treatment and as a take-home system, popular for its’ ease and convenience. The in-office treatment is usually followed with a course of the at-home treatment to maintain the results. KöR involves your dentist’s office making a custom mold of your smile. This mold is used to create a mouthpiece, called a bleaching tray, with which you are sent home to fill with KöR’s bleaching agent and wear on your teeth while sleeping.

KöR’s whitening gel restores the natural ability of our teeth to absorb oxygen, causing stains to fade or even disappear! Teeth have been observed to improve as much as sixteen shades with this treatment. The unique KöR Teeth Whitening system has been specially designed to enable the bleaching agent to achieve maximum results by completely eliminating the effects of your natural saliva and fluids present in the mouth, which diminish its efficacy. The KöR-Seal™ trays completely seal the treated area and provide truly amazing results.With proper care and maintenance, your results can last a very long time.

Opalescence is a take home teeth whitening treatment that offers professional results in the comfort of your own home. Opalescence tooth whitening gel is specially formulated with potassium nitrate and fluoride to reduce tooth sensitivity and strengthen enamel. Your treatment will enhance your smile and improve overall dental health. The active ingredient in Opalescence whitening gel is either carbamide peroxide or hydrogen peroxide (depending on the treatment selected). As oxygen molecules from the whitening agents penetrate the tooth enamel, they spread, breaking apart stains and whitening the entire tooth.

Dr. Gotwalt can work with you to find the right solution for your smile. If you would like to set up a consultation about teeth whitening, call 717.220.4651 or schedule an appointment online.
