Transform Your Smile with In-Office and At-Home Teeth Whitening

Yellowed or discolored teeth can make you feel self-conscious enough to cover your mouth when you laugh and smile. This self-consciousness is not without reason, either. According to a study published by the American Academy of Cosmetic Dentistry, 48 percent of adults surveyed believed that smile was the most important, memorable feature upon first meeting someone else.

Fortunately, teeth whitening is one of the simplest, most cost-effective, and least invasive cosmetic dentistry treatments available. Dr. Len Gerken uses Opalescence® to provide a combination of in-office and take-home whitening and create predictable results customized to your needs. Whitening is one of many cosmetic services offered at our practice in Oro Valley, AZ, and our friendly staff can help you decide whether this procedure is right for your concerns, budget, and goals.

Before whitening your teeth, we will use a shade guide to determine what your goal is and how much treatment is necessary to get there. 

Are You a Good Candidate for Whitening?

Many patients choose teeth whitening as the first step in their cosmetic dentistry treatment plan because it achieves dramatic results without surgery or alteration of the teeth. We typically recommend whitening for patients who:

  • Are in good oral health and are free of gum disease
  • Do not have whitening-resistant crowns, bridges, or porcelain veneers
  • Are not pregnant
  • Have healthy enamel
  • Do not have exposed roots

Good oral health is especially important. Prior to performing any cosmetic procedure, we will assess your gums, teeth, and jaws to ensure that any existing oral health complications are addressed first.

How Does It Work?

Depending on your needs, Dr. Gerken may recommend an in-office procedure, take-home treatment, or a combination of both. Opalescence contains a patented combination of potassium nitrate and fluoride which clings to the surface of your teeth to make your smile as bright as possible.

If you need a dramatic enhancement for a special occasion like a wedding, an in-office whitening treatment may be right for you. This treatment uses a stronger concentration of whitening agents to noticeably brighten your smile in less than an hour. Unlike other whitening treatments, Opalescence is highly effective on its own without the use of ultraviolet lights or lasers, making for a much more comfortable treatment.


For patients who prefer to whiten their smile in the convenience and comfort of their own home, Dr. Gerken can also prepare an Opalescence take-home whitening kit. This kit includes whitening solution and custom trays made of smooth plastic which fit snugly and securely around your teeth. Depending on your schedule, you can whiten your teeth 30 minutes per day or overnight by applying the whitening solution directly to your teeth with the custom whitening trays.

Why Choose Professional Whitening

Although over-the-counter, store-bought whitening pastes and rinses are widely used, they cannot provide the same predictable, safe, and effective results that a professional whitening treatment provides. Under the supervision of Dr. Gerken, you will receive a treatment tailored to your concerns and level of discoloration. While the whitening agents we use are powerful and highly effective, they are also extremely safe.
