If you hope to have a dazzling smile, you need to make sure your pearly whites are actually white. Over the counter teeth whitening is usually very mild and unable to whiten teeth quickly and completely. A visit to the dentist in Highland Park, IL can provide you with ADA approved prescription strength whitening agents, and trays that are custom fit to your teeth. Additionally, your dentist can perform in-office whitening treatment that can have your smile sparkling in no time. Of course, after treatment you will want to limit or avoid tobacco and foods and beverages that are known to stain teeth.
