A fresh, beautiful smile can not only have an effect on your overall appearance – for many people, it can be an essential factor to a healthy self-confidence and success in their careers. Las Vegas cosmetic dentist Joseph G. Willardsen, DDS at True Dentistry offers state-of-the-art treatment options to reduce signs of yellowing and staining for results that can lighten your teeth several shades. Whether you want to make a good impression in the modeling, entertainment, and business industries, or you would simply like to have a great-looking smile when you meet with friends, our in-office procedures and take-home kits can help you enhance the appearance of your teeth for whiter, brighter results.

What is Teeth Whitening?

Teeth whitening is a process that involves the use of bleaching agents to break up stains and discoloration located in the tooth enamel. There are many different teeth whitening methods and systems; however, the most efficient and effective ways to whiten teeth are only available through a dentist’s office. At True Dentistry, we offer state-of-the-art in-office teeth whitening treatments in addition to professional take-home whitening kits that utilize clinical-strength teeth bleaching agents to help patients achieve noticeably whiter smiles.

What Causes Dental Stains and Discoloration?

A gradual yellowing or discoloration of the teeth can occur whether you have taken excellent care of your teeth not. Each person’s teeth are different due to variations in genetics and dental development, and some stain more easily and deeply than others. Some common causes of acquired dental stains and discoloration can include:

  • Natural aging
  • Coffee, tea, wine, and sodas
  • Use of tobacco products
  • Acidic foods and citrus
  • Sweets
  • Dark fruits and berries
  • Medication

Depending upon the nature of your tooth discoloration and the composition of your teeth, Dr. Willardsen will recommend the appropriate method of whitening for achieving the results you desire. In certain instances, teeth whitening techniques might not be the best option for creating a whiter smile, and Dr. Willardsen may discuss other cosmetic options such as porcelain veneers or cosmetic bonding to conceal stubborn discoloration.

Benefits of Teeth Whitening

Professional teeth whitening options can significantly enhance the color of your teeth and give them a whiter, more refreshed appearance. Our professional strength whitening options are much more effective than over-the-counter treatments, and they often result in lightening teeth by up to eight shades or more. Our in-office procedures are virtually painless and you can see the results right after treatment, while our at-home kits allow you the convenience of whitening your teeth on your own time.

In-Office Opalescence® Boost Teeth Whitening

To help restore bright, gleaming smiles, we use the prescription-strength Opalescence® Boost Teeth Whitening System. This easy, in-office cosmetic dentistry procedure combines powerful 38% hydrogen peroxide whitening gel to penetrate tooth enamel and effectively bleach the teeth, and a fluoride solution, which combats tooth sensitivity and strengthens tooth enamel. In about an hour teeth can become significantly whiter. The procedure is often considered comfortable, and the results are immediate. It will not harm your teeth, gums, or dental work.

Take-Home Teeth Whitening

As one of the most effective and popular cosmetic dentistry solutions available to our patients, our take-home teeth whitening kits enable you to brighten your smile in the privacy of your own home. We offer both the KöR® whitening system and the Opalescence® whitening system as at-home options for our patients:

The KöR® at-home whitening system uses specially made KöR-Seal™ trays and strong, patented whitening gels to provide between six to ten hours of whitening activity with each use. This advanced whitening technology breaks down deep enamel stains to reveal a brilliantly white smile. It takes just about two weeks to receive the customized KöR-Seal™ trays after your initial appointment, and then you can begin your whitening treatments at home. Dr. Willardsen will instruct you on exactly how to use the trays and gel for optimal results.


During your appointment, a series of custom take-home whitening trays will be made for you. These trays hold the patented Opalescence® gel and fit comfortably in your mouth as you whiten. Dr. Willardsen will help you decide which Opalescence® formula is best for achieving your goals. It is important to follow his instructions closely in order to achieve the best results. The duration and frequency of your teeth whitening treatments will vary depending on the severity of your discoloration; however, many patients achieve noticeable results in a fairly quick period of time.

FAQs about Teeth Whitening

How long will the results of my teeth whitening treatment last?

Through proper daily dental hygiene, avoidance of staining substances, and regular teeth cleanings, your whitening results can be long-lasting. Some patients choose to perform occasional at-home follow-up treatments to refresh their results and prevent the buildup of new stains. For patients who are interested in a white smile that remains stain-free, porcelain veneers are a stain-resistant option that can keep the smile white and bright for decades.

Does teeth whitening hurt?

Generally, patients describe teeth whitening as a virtually painless process; however, teeth whitening can sometimes cause mild discomfort for patients who have sensitive teeth. For these patients, Dr. Willardsen may recommend the use of toothpaste formulated for sensitive teeth prior to treatment to prevent uncomfortable sensations. Fluoride treatments can also be effective for preventing sensitivity during whitening treatments. If you are concerned about teeth whitening for sensitive teeth, we recommend you speak with Dr. Willardsen about effective preventative measures you can take to create a more enjoyable experience.

Which method of teeth whitening is most suitable for my teeth?

A one-on-one consultation with Dr. Willardsen is the best way to find out which whitening technique is right for you. After some discussion and a thorough examination of your teeth, Dr. Willardsen can explain whether in-office treatment with Opalescence® Boost, at-home whitening, or another cosmetic dentistry procedure can meet your dental needs and smile goals.
