Teeth can be whitened to a lighter shade by using a variety of products that are available in stores and dental offices. Over the counter products will whiten teeth to a certain degree but not substantially. At First Impressions Dental, we offer various whitening services that will brighten your smile and the effects will last longer than over-the-counter whitening products. With all whitening services, instructions for use during whitening as well as post-treatment must be followed. Sensitivity after whitening is very common, and must be managed with professional advice and care.
