Teeth Whitening

Do your yellowed teeth make you cringe every time someone pulls out a camera and says: "Smile!"

Colorado Dental Arts in Littleton, CO, can erase years of stains from your teeth quickly and safely with professional teeth whitening. 

When an important event is on your calendar, turn to Littleton’s trusted local practice to achieve a dazzling smile you’ll love to share.

Why Professional Teeth Whitening? 

There are many at-home teeth whitening options, from whitening toothpastes to gels. Why get professional treatment from a dentist?

Dramatic Improvements 

Dr. Steven Krendl uses professional-grade teeth whitening products that can make your teeth three to eight shades lighter, well beyond what can be achieved with over-the-counter bleaching products. For example, most toothpaste designed for whitening can only achieve results that are one shade lighter. 

Fast Results

In-office whitening is the quickest way to whiten teeth. Noticeable improvements can be seen at your first treatment, which typically takes 60 minutes or less. Alternatively, over-the-counter treatments with their weaker solutions require weeks or months to see any difference.

Safety & Comfort

While teeth whitening is a safe process, it still requires care and attention in how it is performed. Dr. Krendl, who began practicing in 2004, has years of experience safely applying whitening solutions for optimal results and minimal irritation.

A Little More Detail
about Teeth Whitening 

woman having her teeth whitened

In-office options to whiten teeth offered at Colorado Dental Arts are much stronger than the products you can buy in the store. Over-the-counter products use a weaker bleaching agent, typically with about a 10 percent to 22 percent carbamide peroxide content. Professional whitening products, on the other hand, typically contain a hydrogen peroxide concentration ranging from 15 percent to 43 percent. 

During in-office treatment, the hydrogen peroxide solution is applied directly to the teeth and activated with a special light. We will utilize a protective barrier to avoid nearby gum tissue, which can be irritated by whitening solutions.

Another available option is a dentist-supervised, at-home method in which a milder whitening gel is applied to teeth using a custom mouthpiece. For this, our dentist can create a tray to exactly fit your teeth, ensuring maximum contact between the whitening gel and each tooth while avoiding contact with your gums.

Should I Talk
to a Dentist First?

Even if you are going to use an over-the-counter product, you should still consult with our dentist and tap into his professional knowledge. Not every stain responds well to tooth whitening, and it's good to know how much whitening is realistic to expect from simple whitening products like toothpaste.

Dr. Krendl, who has extensive training in cosmetic dentistry, can offer his professional insight about what methods will or will not work in your situation, and he may be able to suggest alternatives better suited for you. 

What about Over-the-Counter Products? 

Whitening toothpaste, bleaching strips, and other over-the-counter products require both time and patience. Then, you may have to settle for less than dramatic results. If you would like to give over-the-counter products a try, we recommend first requesting an appointment with Dr. Krendl, who can advise you on what to expect, what to avoid, and whether teeth whitening is appropriate for your tooth discoloration problem.

Here are some things to think about with over-the-counter products:

Poor Whitening

Over-the-counter products lack the strength to achieve the dramatic whitening available from a dentist. In addition, if you haven't been to a dentist for a while, plaque buildup can interfere with the effectiveness of your whitening product. For the best results, get your teeth professionally cleaned so the whitening solution makes good contact with each tooth.

Uneven Whitening

Tooth-colored fillings, crowns, and bridges will not lighten with over-the-counter products, which can result in uneven color among your teeth.

Irritation and Pain

Whitening solutions should be kept off gums to avoid irritation, so the method of application is important. Some store-bought products use a one-size-fits-all tray to apply the whitening agent. As we all know, one-size-fits-all rarely fits anyone precisely, and this can allow the bleaching solution to irritate tender gums. Tooth sensitivity can also happen if you leave the whitener on too long. 


Dentists use shade guides to determine when you've reached your maximum level of safe whitening. When you use over-the-counter products, you'll have no such guide, and you may be tempted to overbleach and damage your teeth.
