Teeth whitening is one of the most requested cosmetic dental treatments, and for good reason. A brighter smile can boost your confidence, enhance your appearance, and make a great first impression. If you’ve ever wondered just how white your teeth can actually get, you’re not alone.
At Center City Dental, we offer professional teeth whitening in Philadelphia that delivers real results. But what does that mean, exactly? Let’s break it down so you know what to expect before you sit in the whitening chair.

What Affects How White Your Teeth Can Get?
Not everyone’s teeth will respond the same way to whitening. The results depend on a variety of personal factors:
1. Natural Tooth Color
Your natural enamel color sets the baseline. Some people naturally have slightly yellower or gray-toned enamel, which can influence how white their teeth appear after treatment.
2. Type of Stains
Extrinsic stains (caused by coffee, wine, tobacco, etc.) typically respond well to whitening.
Intrinsic stains (caused by medications, trauma, or enamel thinning) may be more resistant to treatment and may require additional cosmetic options, such as veneers.
3. Age
As we age, enamel thins and dentin (the yellow layer beneath) becomes more visible. Whitening can still help, but may not yield ultra-bright results in older patients without further treatment.
4. Type of Whitening Used
Over-the-counter products can lighten your teeth a little. However, professional whitening at a dental office is far more powerful and controlled, often delivering significantly brighter results in just one visit.
What Can You Expect from Professional Whitening?
We offer in-office and take-home whitening options customized for your smile. Our in-office treatments use concentrated whitening agents, typically hydrogen or carbamide peroxide, combined with a special light to accelerate results.
On average, patients see their teeth lighten by six to eight shades in a single session, depending on their starting shade and the severity of staining. That’s a noticeable, yet natural-looking difference!
Can Teeth Be “Too White”?
Absolutely. Ultra-white, unnaturally bright teeth can sometimes appear fake or chalky, especially if they don’t match your skin tone or the whites of your eyes. The goal of whitening should be to enhance your natural smile, not erase all character from it.
That’s why professional treatment is so important. We help you choose the right shade based on your facial features, smile line, and goals, so your results look bright and believable.
How Long Do Whitening Results Last?
Results typically last between 6 months and 2 years, depending on your lifestyle and oral care habits. To maintain your newly whitened smile:
- Avoid stain-causing foods and drinks (coffee, red wine, berries)
- Rinse with water after meals
- Use a whitening toothpaste or touch-up gel
- Schedule routine cleanings and checkups
We also offer take-home trays for occasional touch-ups, so you can keep your smile glowing year-round.
Who Should Avoid Whitening?
While most people are good candidates, whitening may not be ideal if you:
- Have untreated cavities or gum disease
- Are pregnant or breastfeeding
- Have dental restorations (crowns, veneers, fillings) in visible areas—they won’t whiten
- Experience chronic tooth sensitivity
Not sure if it’s right for you? We’ll evaluate your oral health and discuss your goals during a cosmetic consultation.
