Professional teeth whitening uses dentist-supervised, professional-strength gel to safely lighten stains and brighten your smile. It's more effective and more even than over-the-counter kits, and it can be done in-office or with custom take-home trays. Most patients see noticeably whiter teeth and keep their results bright with simple touch-ups.
Teeth whitening lightens the color of your teeth by safely breaking down stains that build up over time. Professional whitening uses stronger, carefully controlled whitening gel than anything you'll find at the store, and because it's supervised by your dental team, it's safer and gives more even, predictable results.
We offer professional whitening tailored to you. Depending on your goals and sensitivity, that may mean in-office whitening for fast results or custom take-home trays you use on your own schedule. We'll recommend the approach that fits your smile and your lifestyle.
For the brightest, longest-lasting results, we usually start with a clean, healthy mouth, so a regular cleaning and checkup is a great first step.
Use our innovative FlashSmile tool to see what you’d look like with a whiter smile!
Whitening is a great option for many people. You may be a good candidate if you:
Note: Whitening only works on natural tooth enamel, so it won't change the color of existing crowns, veneers, or fillings. If your discoloration is deeper or comes from past dental work, we'll talk through options like bonding or veneers.
Professional whitening is especially effective for surface stains, such as:
Yellowing or general dullness
Coffee, tea, and red wine stains
Stains from berries and other deeply colored foods
Tobacco staining
Gradual darkening that comes with age

The cost of whitening depends on the option you choose, in-office or custom take-home, and your specific goals. Because whitening is cosmetic, it's typically not covered by dental insurance, though we'll always review your benefits with you.
To keep treatment easy, we offer financing through CareCredit and Cherry, and members of our in-house membership plan receive 15% off treatments like whitening. We'll give you a clear, personalized quote at your visit.
Whitening is safe and effective, but a few things are worth knowing. Some people notice temporary tooth sensitivity, which usually fades quickly, and we can adjust your treatment to minimize it. Whitening also isn't permanent: results last a while but gradually fade, so occasional touch-ups keep your smile bright.
Whitening also won't lighten existing crowns, veneers, or fillings, and deeper, intrinsic stains may not respond as well as surface stains. If whitening isn't the best fit, we'll honestly walk you through alternatives such as dental bonding or veneers, and we'll always recommend treating any decay or gum issues first.
Store-bought kits can be uneven and harsh on your gums. With us, whitening is professional-strength, dentist-supervised, and customized to your smile and sensitivity, so your results look natural and even, and the experience stays comfortable.
As a woman-owned practice in the heart of the Loop, we pair modern dentistry with genuine, personal care, and a comfort-first approach that makes every visit easy.

It depends on whether you choose in-office whitening or custom take-home trays, and on your goals. Whitening is cosmetic, so it's typically not covered by insurance, but we offer financing and a 15% member discount, and we'll give you a clear quote at your visit.
Results usually last several months to a couple of years, depending on your habits. Coffee, tea, red wine, and tobacco fade results faster, while good oral care and occasional touch-ups keep your smile bright longer.
Yes. Professional whitening is stronger, more even, and dentist-supervised, so it works better and protects your gums. Store-bought kits are weaker and can cause uneven results or gum irritation. Professional whitening is best when you want reliable, even results; a kit may suit only very minor touch-ups.
No. Whitening only lightens natural tooth enamel, so existing dental work won't change color. If you have crowns or veneers in your smile zone, we'll plan around them so your smile looks even, and discuss matching options if needed.
Professional whitening is safe and comfortable. Some people feel temporary sensitivity that fades quickly, and we customize your treatment and protect your gums to keep you comfortable.
