What Causes Tooth Discoloration?
Your teeth can become stained or yellowed for a variety of reasons — many of which are completely normal. Common causes include:
- Food and drinks: Coffee, tea, red wine, berries, and dark sodas are the leading culprits
- Tobacco use: Smoking and chewing tobacco cause deep, stubborn staining
- Age: Over time, the outer enamel layer wears down, revealing the naturally yellowish dentin underneath
- Medications: Tetracycline antibiotics and certain antihistamines can cause intrinsic staining
- Fluorosis: Excessive fluoride exposure during childhood tooth development
- Trauma: An injury to a tooth can cause it to darken from the inside
Even if your teeth are perfectly healthy, discoloration can make them look older or less appealing. That's why teeth whitening remains one of the most requested services at our Queens dental office — and one of the most cost-effective ways to upgrade your appearance.
Our In-Office Teeth Whitening Treatment in Queens
Our in-office whitening uses Opalescence®, a professional-grade system trusted by dentists nationwide. Here's what to expect during your appointment at our Kew Gardens, NY office:
Step 1 — Dental ExamBefore whitening, we perform a dental exam and X-rays to ensure your teeth and gums are healthy and ready for treatment. If we spot any cavities or gum issues, we'll address those first — whitening over untreated decay can cause sensitivity and uneven results.
Step 2 — Gum ProtectionWe apply a protective barrier to your gums and soft tissue before treatment begins, keeping the whitening agent focused only on your enamel.
Step 3 — Whitening ApplicationThe professional whitening gel — containing either hydrogen peroxide or carbamide peroxide — is applied to your teeth. These active ingredients penetrate the enamel and break apart the molecular bonds that cause staining, revealing the whiter tooth structure underneath.
Step 4 — Results You Can SeeIn just one hour, you'll leave our Queens dental office with teeth that are visibly brighter — often 3 to 8 shades lighter than when you walked in.
Is Teeth Whitening Right for You?
Professional whitening works best on natural tooth enamel. It does not change the color of crowns, veneers, or bonding. If you have restorations that will be visible after whitening, you may want to discuss replacing them to match your new, brighter smile.
Whitening is ideal for patients with:
- Yellow or brown surface staining
- Discoloration from coffee, tea, or wine
- Age-related enamel darkening
- Staining from tobacco
If you have deep intrinsic staining (from medications like tetracycline), porcelain veneers in Queens or cosmetic bonding may be better options. Our Queens dentists will help you find the right solution during your consultation.
We also recommend scheduling a professional teeth cleaning before your whitening appointment to remove surface buildup and ensure the most even, effective result.
How Long Does Teeth Whitening Last?
Results vary from patient to patient, but most people enjoy noticeably whiter teeth for 1 to 3 years following in-office treatment. The following factors affect how long your whitening lasts:
- Diet: Frequent coffee, tea, wine, or dark food consumption will shorten results
- Tobacco: Smoking is one of the fastest ways to restain teeth
- Oral hygiene: Consistent brushing, flossing, and regular dental cleanings in Queens help maintain brightness
- Touch-ups: A take-home whitening kit from our office can extend your results between visits

Teeth Whitening & Your Overall Dental Health
Whitening is a cosmetic treatment, but your overall oral health matters just as much. Before any cosmetic procedure, we check for underlying issues like decay, cracked teeth, or gum disease that could interfere with treatment.
If you're due for a checkup, a dental exam and cleaning at our Queens office is the right first step. Patients with existing tooth-colored fillings should also know that fillings won't whiten — we can discuss options for matching your restorations to your brighter smile after treatment.
