Teeth Whitening

Over time, our teeth can become stained due to age, genetics, certain foods and drinks, and other factors.

Fortunately, teeth whitening can give you a brighter, whiter smile quickly and safely.

At Dr. John P. Goodman's practice in Kansas City, MO, we offer in-office and take-home teeth whitening treatments.

​Tired of Lackluster Over-the-Counter Whitening? Professional Whitening Offers the Very Best Results

In-office teeth whitening

While it can be simpler to pick up a whitening toothpaste or set of whitening strips at the drugstore, you won't find the same caliber of results as dentist-provided bleaching.

Because it has a more concentrated formula, it can dramatically lighten the shade of stains dulling your teeth. Our team offers both at-home and in-office options, allowing you to choose what works best for your needs.

Plus, with our dentist conducting your treatment, you'll have complete peace of mind.

Try Philips Zoom! In-Office Treatment

With dentist-directed whitening, you can have brighter results in less time. Philips Zoom!® in-office teeth whitening can be performed in just one appointment. It contains a higher concentration of hydrogen peroxide compared to over-the-counter products like whitening strips or whitening toothpastes.

In-Office Treatment Timeline

We proudly offer Philips Zoom!® in-office teeth whitening at our Kansas City practice. This revolutionary procedure produces fast, effective whitening results with little to no discomfort. Each session typically goes like this:
In-office whitening is best if you want to brighten your smile for a big event and you don't have much time.

A specialized mouth guard is placed to protect your gums from coming into contact with the bleaching gel. This prevents the irritation that is often experienced when patients use over-the-counter, at-home kits to whiten their teeth.

Gel Application

Professional-strength tooth whitening bleaching gel that contains hydrogen peroxide is applied evenly to your teeth, ensuring complete coverage of all exposed surfaces, angles, and corners.

Stain Removal

As you recline comfortably in the chair, a special dental light is used to activate the bleaching power of the hydrogen peroxide and other ingredients in the tooth whitening gel. The treatment length and use of the specialized light allow the solution to penetrate deeply into the enamel and remove tough stains.

Repeat As Needed

You can undergo up to three 15-minute tooth whitening treatments during a single appointment, depending on the degree of staining and discoloration. Patients who choose this option can leave our Kansas City office with a noticeably whiter, brighter smile in under one hour.

Glo Science Professional At-Home Whitening

The Glo Science Professional take-home teeth whitening kit uses custom trays and whitening gel. For patients undergoing certain procedures, we may be able to offer a discount on the Glo Science take-home kit.

Take-Home Teeth Whitening Treatment Timeline

Patients who want to whiten their teeth at home can opt for our dentist-supervised take-home bleaching kits. We offer Glo® Science Professional at our Kansas City practice to help patients achieve tooth whitening with better results than store-bought products such as whitening toothpastes and whitening strips.
Performed on its own, a take-home kit serves as a more affordable, convenient, and gradual option for brightening your teeth.

If you select take-home treatment, Dr. Goodman will first need to fabricate your set of custom bleaching trays. To do this, we will take impressions of your teeth and send them to our dental lab.

Receiving Your Whitening Kit

Once the trays are complete, we will assess them to ensure they fit properly. Your trays should rest snugly and comfortably over your teeth. Dr. Goodman will provide you with the concentrated Glo gel which contains hydrogen peroxide.

Applying the Gel

You will dispense the gel directly into the bleaching trays. You will then insert the trays in your mouth and wear them for the recommended amount of time. The oxygen molecules will penetrate the enamel and begin to break apart the stains to whiten your teeth.

Wearing the Trays

The amount of wear time will depend on the type of gel you use. In many cases, patients will wear their trays for about 15 to 30 minutes. This will need to be done daily for at least two weeks.


Patients can touch up their results every four to six months to counter any dullness.

What Are the Benefits of Professional Teeth Whitening? See for Yourself During a Free Consultation

Professional teeth whitening at our Kansas City dental office can deliver a brilliant, natural-looking smile. This treatment offers several advantages, like:

Fast Results

Professional teeth whitening offers quick results. Those who choose an at-home kit can achieve their desired smile gradually over the course of a few weeks. Patients who undergo an in-office treatment can lighten their smile by several shades in a single appointment.

Safety and Effectiveness

Over-the-counter whitening products can be too abrasive and may harm the protective outer layer of the teeth. However, dentist-supervised teeth whitening uses a concentrated hydrogen peroxide gel. As a result, it is safer, less invasive, and more affordable than alternative treatments.

Boosted Self-Confidence

A brighter, more attractive smile can have a positive impact on various aspects of your life, including your career and social life. Being able to show off an enhanced, dazzling smile is life-changing for many of our Kansas City patients.

Can I Use Insurance For Teeth Whitening?


Because it's a cosmetic procedure, teeth whitening will not be eligible for insurance. Still, because it provides consistent results using a higher concentration of hydrogen peroxide, it can be a more cost-effective way to whiten your smile than the alternatives.

Paying for Your Teeth Whitening

Kansas City, MO, patients can cover the cost of their treatment using in multiple ways. Here's what you need to know.

We Have Free Consultations

Your initial teeth whitening consultation can be completely free. That way, there's no obstacle of cost blocking you from exploring your cosmetic options.

We Have Multiple Payment Options

For your convenience, you can cover the cost of your teeth whitening using cash or most major credit cards.

We Accept Financing

Instead of paying for the costs of your teeth whitening all at once, you can pay in manageable installments over time. Our office accepts CareCredit® financing — and we're happy to go over how it works.

Types of Stains and Discoloration
And Knowing Which One Responds to Whitening

Even with proper brushing and flossing habits, it can be very difficult to maintain bright, white teeth. Our teeth whitening treatments can eliminate stains in a safe and effective manner. When it comes to tooth discoloration, there are two types: extrinsic and intrinsic.

Extrinsic Stains

Extrinsic stains affect the outer layers of the teeth. The stains can develop as a result of drinking beverages such as coffee or wine, eating foods like berries or mustard, or using tobacco products. Fortunately, extrinsic dental stains respond exceptionally well to teeth whitening.

Intrinsic Stains

Intrinsic stains affect the innermost layers of a tooth. This type of discoloration can be caused by genetic conditions, certain medications, or dental trauma. Since they're deep within the tooth, they do not improve significantly with teeth whitening. They may be better treated with veneers or bonding.

Teeth Whitening Alternatives
Offered by Our Dentist

If you are not a candidate for teeth whitening, there are other treatments that can help you achieve a brighter, more attractive smile. These include:

Dental Bonding

During dental bonding treatment, tooth-colored composite resin is applied to the tooth to conceal discoloration as well as minor cosmetic flaws, such as chips, cracks, and slight misalignment. Dr. Goodman will apply the composite resin, mold and shape it, and harden it with a curing light. As a final step, the teeth are polished to a natural-looking shine.

Explore Dental Bonding

Porcelain Veneers

One of the most popular cosmetic treatments available, porcelain veneers can alter the shape, size, or color of the teeth. Custom-crafted by a skilled ceramist, veneers adhere to the front surfaces of the teeth for a truly transformed smile. Generally, porcelain veneers can be placed in just two office visits.

Snap-On Smile

Designed to fit over your teeth, Snap-On Smile® can instantly transform your smile, making it whiter, as well as more balanced and symmetrical. Though most patients only use this option as a temporary solution, it can give you a boost of confidence while you are waiting to complete your desired cosmetic treatment.

Explore Snap-On Smile

Choose a Kansas City Practice With Plenty of Options

Another benefit of choosing our practice is the fact that Dr. Goodman can combine teeth whitening with other cosmetic procedures to improve your entire smile, such as orthodontics. He's happy to listen to your goals and create a custom plan called a smile makeover to safely refine your gums and teeth.

And if you're considering receiving porcelain veneers or dental bonding, he may recommend whitening beforehand to optimize your overall results. Crowns, bridges, and other restorations will not respond to whitening.

Teeth Whitening FAQs

How Soon Will I See Whitening Results?

The results of teeth whitening are typically immediate. However, it is important to understand that this treatment does not prevent future stains from occurring.

How Often Will I Need Touch-Ups?

You will likely need touch-up treatments to maintain long-term results. Depending on the whitening method used, patients may need treatment every six to 12 months. If you smoke or consume dark-colored beverages or foods, you may need more frequent touch-ups.

How Can I Maintain My Results?

We always recommend seeking professional treatment at our Kansas City practice rather than using over-the-counter whitening strips and other products. You should also follow our post-treatment advice to keep your smile looking bright and beautiful.

Tips to Keep Your Smile Beautiful
From Our Trusted Cosmetic Dentist

Dr. Goodman will make sure you have all the information you need to know about protecting your beautiful results. He's also happy to help with the process by offering follow-up appointments, general dentistry visits, and a variety of custom cosmetic dentistry procedures. After your whitening treatment is complete, he may advise you to:

  • Brush twice a day
  • Floss once a day
  • Attend regular cleanings and exams
  • Limit coffee, tea, soda, and red wine
  • Avoid dark or acidic foods and drinks
  • Refrain from using tobacco products
