Professional teeth whitening in Venice, FL by Dr. Meenachi Sellappan, DDS.
Effectively removes coffee, wine, tobacco and aging stains — both surface (extrinsic) and deeper (intrinsic) discoloration.
KöR Whitening is a professional system designed to treat even stubborn stains, including tetracycline staining.
Choose in-office whitening, custom take-home trays or a combination for your best result.
Whitening works on natural teeth, but does not change the color of veneers, crowns, fillings or other restorations.
Results are long-lasting with good oral hygiene and occasional maintenance.
Most patients experience minimal to no sensitivity with the KöR system.
Investment typically ranges from $500–$1,200, depending on the option and your goals. Professional whitening uses hydrogen peroxide or carbamide peroxide to break apart pigment in the enamel and dentin.
Brighter teeth. A more confident you.
A whiter smile can make you look more refreshed, healthy and confident — and it's one of the simplest, most conservative ways to enhance your appearance.
Coffee, tea, red wine, tobacco and ordinary aging gradually dull the natural luminosity of teeth. Professional whitening reverses that, safely and predictably, under the supervision of a cosmetic dentist. Unlike drugstore strips and gels, the professional-grade systems we use are calibrated to your enamel, protect your gums, and deliver a noticeably whiter result without the guesswork.
While whitening can dramatically improve the appearance of natural teeth, it does not change the color of veneers, crowns, fillings or other restorations. If you have extensive discoloration or the restorations in your smile do not match, porcelain veneers may be a better option. During your consultation, we'll evaluate your goals and recommend the most appropriate treatment to help you achieve a brighter, more confident smile.

KöR is a professional deep-bleaching whitening system designed to deliver deeper, more predictable results with less sensitivity — even for stubborn stains. It's the standard we choose because it works, and because our patients deserve the best.
KöR gel is refrigerated to preserve its strength, so it stays effective until the moment you use it.
Your trays are custom-made to fit your teeth, limiting saliva contamination and keeping the gel in close contact with the enamel for consistent results.
KöR's sustained oxygen diffusion penetrates enamel and dentin, making it highly effective for challenging stains — including tetracycline discoloration.
Teeth can look dull or discolored for different reasons. Some stains live on the surface and are easy to remove, while others are deeper inside the tooth. Professional whitening doesn't bleach teeth in the household sense — it uses an oxygen-releasing agent that diffuses through enamel and into dentin, breaking apart the pigmented molecules responsible for discoloration.
Surface discoloration on the enamel — the hard, translucent outer layer of the tooth. They come from coffee, tea, red wine, tobacco and deeply pigmented foods, and sit on the outside where polishing and whitening reach them most easily.
Discoloration within the dentin — the softer yellow layer beneath the enamel. Caused by aging, certain medications such as tetracycline antibiotics, excess fluoride, or trauma to a tooth. Because the color sits inside the tooth, intrinsic stains need a whitening agent that penetrates the enamel to lighten the dentin underneath, which is why they require a deeper approach like KöR.
The two agents used are hydrogen peroxide, a fast-acting whitening agent used mainly for in-office treatment, and carbamide peroxide, a slower-releasing agent that breaks down into hydrogen peroxide and is ideal for take-home trays worn over several hours.
