 Welcome to PK Cosmetic and Family Dentistry

The goal of the dentists, dental hygienists, and support staff at PK Cosmetic and Family Dentistry is to provide high-quality oral health care for men, women, and families living in and around Sterling, Virginia, and throughout Loudoun County.  

The team at PK Cosmetic and Family Dentistry offers years of experience, convenient hours, plenty of available parking, and state-of-the-art technologies and equipment, including the iTero® intraoral scanner and diagnostic imaging with digital X-rays.

Unlike other dental providers in the area, the team also offers all of its services under one roof, so patients don’t have to worry about getting referrals or scheduling appointments at various facilities. The team offers Saturday appointments for select services, evening hours for working individuals, and same-day appointments for dental emergencies.

In addition to offering general dentistry services such as dental cleanings, tooth extractions, treatment for gum disease, and treatment for toothaches, the team also specializes in cosmetic and restorative dentistry procedures. Patients regularly seek the expertise of the dentists on staff to restore their smiles with crowns, dental implants, fillings, removable dentures, porcelain veneers, and teeth whitening.

The dental team also offers more complex surgical procedures, including restorative dentistry, emergency dentistry, wisdom teeth removal, root canal therapy, and tooth extractions. Adolescents and adults can also access orthodontic treatment with cutting-edge Invisalign® oral aligners. At PK Cosmetic and Family Dentistry, the team sets aside plenty of time to work with each patient, listening to their unique concerns and developing treatment plans that align with their needs. Additionally, the team accepts all types of insurance, making payment easy and hassle-free.

To access the best, most comprehensive oral health care, partner with the team at PK Cosmetic and Family Dentistry. Request your appointment today by calling the office or using the online booking tool.

It’s difficult to fight a bad reputation, so root canals carry the decades-old stigma as a painful procedure. The fact is, you’re more likely to be in pain before the root canal. Contemporary dental techniques prevent the pain you may fear.
