Your Trusted Family Dentist in Sterling, VA
PK Family & Cosmetic Dentistry has long been a trusted dentist in Sterling, VA for families who want a wide range of care in one convenient location. We’re a two-doctor practice built around a simple idea. You shouldn’t have to drive across Loudoun County to get every kind of dental care. With Dr. Kourosh Kianpour and Dr. Mojgan Partovi and their combined decades of experience, we offer a wide range of care in one convenient location, from cleanings and checkups to implants, restorative work, cosmetic smile design, and emergency visits when something can’t wait. Both doctors are University of Maryland-trained, and our patients stay with us for years because we treat every visit as a relationship rather than a transaction.
Our office sits just off Harry Byrd Highway (Route 7) near Cascades Marketplace, making us easy to reach for families throughout Sterling, Potomac Falls, Countryside, Ashburn, Dulles, and the surrounding Loudoun County communities. Inside, you’ll find digital imaging, laser dentistry, and sedation options that make treatment more precise and far more comfortable than you might expect, especially for kids and anyone who feels uneasy in the dental chair. We’re also in-network with most major PPO plans, and we offer an in-house benefits plan for patients without insurance.
From your child’s first checkup to your own smile makeover, you’ll always know what’s happening and why before any treatment begins. New patients and longtime patients alike are always welcome at our Sterling, VA dental office.

Regular Dental Cleanings for a Healthier Smile
Preventive care is the foundation of a healthy smile. Our professional dental cleanings go beyond what a toothbrush can do at home — removing built-up plaque and tartar, polishing your teeth, and giving our team a chance to catch any concerns early before they become costly problems.
We recommend cleanings every six months for most patients, and our friendly hygienists make the experience comfortable and thorough for patients of all ages. Keeping up with regular visits is one of the simplest things you can do for your long-term oral health.

Enhance Your Smile
Our smile enhancement services are designed to correct imperfections and give you the smile you’ve always wanted. Whether you’re looking to brighten stained teeth or correct chips, gaps, and alignment, our dental office in Sterling, VA offers solutions tailored to your goals.


Dental Implants: Restore Function and Aesthetics
If you’re struggling with missing teeth, dental implants offer a permanent, natural-looking solution. Our team has extensive experience in placing dental implants and restoring both single teeth and full arches. Dental implants support jawbone health, restore chewing ability, and enhance your overall oral health.
From consultation to placement, we guide you through the entire process with care and clarity.
Emergency Dental Care When You Need It Most
Dental emergencies don’t follow a schedule. If you’re experiencing pain, swelling, or trauma, contact our office right away. We prioritize urgent appointments and do our best to provide same-day care to relieve your discomfort and restore your smile.
