Why Choose Professional Teeth Whitening?

Teeth naturally become stained and discolored over time due to aging, dietary habits, and lifestyle factors such as:

  • Coffee and tea
  • Red wine
  • Tobacco use
  • Certain medications
  • Natural enamel thinning

While store-bought whitening kits may seem convenient, they often fail to deliver consistent results and may cause sensitivity due to poorly fitted trays or low-quality whitening gels.

Customize with Our Cosmetic Dental Team

At DentalPolitan, we use professional-grade whitening systems that are proven to be safe and effective. Our treatments are customized to your dental profile to minimize sensitivity and maximize results, giving you a noticeably brighter smile in less time.

Benefits of Professional Teeth Whitening

Professional whitening at DentalPolitan goes beyond a brighter smile—it’s an experience designed to renew your confidence and elevate your everyday interactions. Choosing expert care ensures safe, consistent, and lasting results that over-the-counter products simply can’t match.

  • Immediate Transformation: In just one appointment, your teeth can be several shades lighter, giving you a refreshed, radiant look for any occasion.
  • Safe & Comfortable Care: With ADA-approved gels and customized trays, sensitivity is minimized while your enamel remains protected.
  • Even, Natural Results: Our professional systems lift deep stains and create a uniformly bright smile—without the patchiness often seen with store-bought kits.
  • Long-Lasting Brightness: With proper maintenance and touch-ups, your results can last months to years, making whitening a long-term investment in your smile.
  • Confidence in Every Setting: From professional meetings to social events, a luminous smile helps you feel polished, youthful, and self-assured.

At DentalPolitan, whitening is more than a cosmetic service—it’s a step toward aligning your appearance with your beautiful personality and lifestyle.

Why Choose Professional Whitening Over Store-Bought Products?

While whitening toothpastes and drugstore kits may promise quick results, they rarely deliver the same level of brightness or safety as professional care. Over-the-counter options often rely on abrasive ingredients or weak bleaching agents that can only lift surface stains—and sometimes cause sensitivity without producing a noticeable change.

At DentalPolitan, our whitening treatments use prescription-strength gels applied with precision for even, predictable results. Unlike one-size-fits-all trays or strips, our customized trays spread the whitening agent across every visible surface of your teeth while protecting your gums and enamel. 

The result is a dramatically brighter smile that looks natural, feels comfortable, and lasts significantly longer than anything you’ll find in a store.

Our Teeth Whitening Services

We offer two professional whitening options, depending on your preference and timeline:

If you want immediate results, our in-office whitening system can brighten your teeth by several shades in a single appointment. This advanced procedure uses a professional-strength bleaching agent activated by a special light to lift deep-set stains and discoloration.

Prefer to whiten your teeth gradually and in the comfort of your own home? We provide custom-made trays and professional whitening gel for safe, convenient at-home use. These kits are more effective than over-the-counter alternatives and allow you to control your results over a period of days or weeks.

Both options are designed to produce whiter, more consistent, and longer-lasting results than anything available in stores.

How Do I Know Which is Right for Me?

Both whitening options at DentalPolitan deliver powerful, professional results—the difference comes down to your lifestyle and goals. If you’re looking for immediate, dramatic brightness before an important event, in-office whitening can lighten your teeth by several shades in a single visit. If you prefer a more gradual, flexible approach, our custom take-home kits allow you to whiten at your own pace with the same professional-strength gel used in the office.

Not sure which option fits your needs best? During your consultation, Dr. Kumar will evaluate your smile, discuss your goals, and recommend the treatment that will help you achieve the radiant results you’re looking for.

Why Opalescence for Tooth Whitening?

At DentalPolitan, Dr. Kumar selects whitening systems that balance safety, effectiveness, and comfort. That’s why we offer Opalescence™ and Opalescence Go™, two of the most trusted professional whitening options available today.

Both systems use advanced formulas that strengthen enamel, reduce sensitivity, and provide long-lasting brightness. With Dr. Kumar’s guidance, you’ll be matched with the whitening system that suits your lifestyle and ensures radiant results, safely and confidently.

Understanding Your Tooth Whitening Candidacy

Being a candidate for tooth whitening isn’t hard. We recommend that you have healthy teeth and gums.

Intrinsic stains can be caused by medications or dental trauma, and they are discolorations that come from your dentin being discolored. Extrinsic stains come from your top layer of enamel being discolored. Most tooth whitening solutions treat mainly extrinsic stains.

If you are struggling with intrinsic stains, whitening may not alleviate those stains effectively. Instead, we recommend veneers or composite bonding to cover intrinsic staining.

If I Already Have Tooth Sensitivity, Can I Get My Teeth Whitened?

Dr. Kumar offers Opalescence products, which mitigate sensitivity during your treatment. If you are concerned about tooth sensitivity, an in-office option for your teeth whitening may be the safest option. Dr. Kumar will be able to specially formulate the amount of whitening gel, and can do an on-and-off again method while you whiten, so your teeth do not become overly sensitive.

Using a toothpaste for sensitive teeth after your appointment for a couple of days can also reduce any lingering sensitivity you may have.

Frequently Asked Questions About Teeth Whitening

Yes. When performed under the supervision of a dental professional, teeth whitening is a safe and effective procedure. At DentalPolitan, we use ADA-approved products that protect your enamel and minimize sensitivity.

Results typically last from 6 months to 2 years, depending on your oral hygiene and lifestyle habits. Regular brushing, avoiding staining foods, and periodic touch-ups can help extend the brightness of your smile.

Whitening is most effective on natural tooth enamel. It will not change the color of crowns, veneers, composite fillings, or other restorations. During your consultation, we’ll evaluate your smile and recommend the best solution based on your needs.

Some patients experience temporary sensitivity after whitening, especially to hot or cold beverages. This usually subsides within a few days. We offer desensitizing agents and recommend using toothpaste formulated for sensitive teeth before and after treatment.

Most patients see an improvement of 5–8 shades after in-office whitening. Results may vary based on the original shade of your teeth and the cause of the discoloration.

It is best to wait until after completing orthodontic treatment to ensure even whitening. For patients using Invisalign®, we may offer take-home trays that are compatible with your aligners in specific cases.

We recommend avoiding staining foods and drinks for at least 24–48 hours after treatment. Stick to light-colored, non-acidic foods such as chicken, rice, potatoes, bananas, and water.

In-office whitening is generally safe every 6–12 months, depending on your enamel health. Take-home kits can be used more frequently for maintenance, under the guidance of our team.

Absolutely. Professional whitening delivers faster, more reliable results than any over-the-counter product. It’s one of the most cost-effective ways to boost your appearance and confidence, especially when performed by an experienced cosmetic dentist like Dr. Kumar.
