Brighten Your Smile Safely and Effectively with Professional Whitening

A bright, confident smile makes a lasting impression. At Waterfront District Dental, we offer professional teeth whitening treatments that safely remove years of stains and discoloration—helping your smile look healthier, younger, and more radiant.
Under the care of Dr. Bart Knowles, DMD, our team combines advanced whitening technology with a personalized approach to deliver beautiful results that over-the-counter products simply can’t match. Conveniently located in Downtown St. Petersburg’s Waterfront District, we make it easy to achieve a brighter smile in as little as one visit.
Why Choose Professional Teeth Whitening
While store-bought whitening kits may offer minor improvements, they often fall short of professional results and can cause sensitivity or uneven bleaching. At Waterfront District Dental, we use clinically tested, dentist-supervised whitening systems that deliver noticeably whiter teeth safely and effectively.
Benefits of professional whitening include:
- Brighter, longer-lasting results
- Reduced tooth and gum sensitivity
- Custom treatment for your enamel type and goals
- Safe application and consistent color results
- Options for in-office or take-home whitening
Whether you’re preparing for a special occasion or simply want to refresh your look, professional whitening is one of the quickest ways to enhance your smile.
How Professional Whitening Works
Our whitening systems use medical-grade gels containing active ingredients that gently break down deep-set stains caused by food, coffee, wine, tobacco, or natural aging.
At your consultation, Dr. Knowles will assess your teeth and recommend the best option:
- In-Office Whitening:
- Delivers immediate results in about one hour.
- Ideal for patients seeking a dramatically brighter smile in a single visit.
- Delivers immediate results in about one hour.
- Custom Take-Home Whitening Kits:

Both options are safe, effective, and tailored to help you achieve your desired shade of white comfortably.
What to Expect at Your Whitening Appointment
During your whitening visit, you can expect:
- Initial Exam: Dr. Knowles will evaluate your teeth and gums to ensure they’re healthy and suitable for whitening.
- Preparation: A protective barrier is placed over your gums and lips.
