Teeth-Whitening

Your Smile Could Be Much Brighter


If asked what they would like to improve most about their smile, many people often choose brighter teeth. Many also consider their smiles an important asset, and believe that an unattractive one can negatively impact their social and professional lives. Professional teeth-whitening offers a quick and highly-effective solution to brightening stained, dulled teeth, and is the most popular cosmetic dental treatment today.

Teeth-Whitening that Fits You Best

Many people don’t see the results they want with over-the-counter OTC whitening strips, toothpastes, or mouthwash. With our professional, cosmetic teeth-whitening kits, we can design custom bleaching trays that fit comfortably over your teeth to hold the bleaching gel to their surfaces, and keep saliva from diluting the gel. Usually, professional home teeth-whitening takes about 7-10 days to produce optimal results. You can wear your trays for a few hours each day or evening, or you can wear them overnight, if you prefer.

If you prefer a faster way to brighten your smile, we also offer in-office whitening that we can perform in just a single visit to our office. In-office teeth-whitening involves gently stimulating the gel after we’ve carefully applied it to your teeth surfaces, which can achieve optimal results and brighten your smile significantly in just over an hour.

Brighten your smile quickly and conveniently

Custom, professional teeth-whitening can erase even some stubborn teeth stains to improve your smile in the most convenient manner.

Frequently Asked Questions

Professional teeth whitening is safe when performed under a dentist’s supervision. It uses controlled bleaching agents that effectively remove stains without weakening enamel. However, overuse of at-home products can sometimes lead to sensitivity or irritation.

The results of teeth whitening can last anywhere from several months to up to 2–3 years, depending on the method and your lifestyle habits. Professional treatments typically last longer than over-the-counter options. Factors like diet, smoking, and oral hygiene play a major role in how long the brightness lasts.

Teeth whitening is most effective on surface (extrinsic) stains caused by food, drinks, or smoking. Deeper, internal stains from medications or trauma may be harder to treat and might require alternative cosmetic options. A dentist can evaluate your teeth and recommend the best solution.

After whitening, it’s best to avoid stain-causing foods and drinks like coffee, tea, red wine, and dark-colored sauces for at least 24–48 hours. During this time, your enamel is temporarily more porous and can absorb stains more easily. Maintaining good oral hygiene also helps preserve your results.

Teeth whitening can still be an option if you have sensitive teeth, but it should be approached carefully. Dentists often use lower-concentration whitening agents or desensitizing treatments to minimize discomfort. You may experience mild, temporary sensitivity, but it typically fades within a few days after treatment.
