Common Questions About Our Gaithersburg Dental Office
Do you accept my dental insurance?
We accept most major PPO dental insurance plans and file claims directly on your behalf to minimize your hassle. Because individual employer plans and coverage levels vary, contact us to verify your specific benefits before starting treatment. For larger cases that exceed your annual insurance maximum, we offer CareCredit financing to keep out-of-pocket costs manageable.
Do you offer a new patient special?
We offer an introductory new patient special for first-time visitors that includes a comprehensive clinical exam, a professional preventive cleaning, and a complete set of diagnostic X-rays. Please contact our office for current pricing and to confirm eligibility, as the standard cleaning depends on your clinical needs. If active periodontal gum disease is diagnosed during your exam, you may require a specialized deep cleaning instead.
Do you offer options for patients without insurance?
Yes, we offer the Dental Smile Club membership to help uninsured individuals and families access affordable preventive care. Members receive two clinical exams, two professional cleanings, two fluoride treatments, and one set of diagnostic X-rays per year, plus a 15% discount on restorative and cosmetic treatments. Contact our office for current membership pricing, as rates are subject to change.
What should I do for a dental emergency after hours?
If you experience a dental emergency outside our normal operating hours, call our main office number immediately to hear our triage instructions. A team member will evaluate your symptoms to coordinate the fastest possible care, and we frequently reserve same-day slots for acute pain or broken teeth. For severe facial swelling, continuous bleeding, or major head trauma, go directly to the nearest hospital emergency room.
At what age should my child first see the dentist?
The American Academy of Pediatric Dentistry recommends scheduling your child’s first dental visit by their first birthday, or when their first baby tooth emerges. At Tong Dental Care, we help children feel safe using a dedicated kids’ game room, ceiling-mounted chairside SmartTVs, and a gentle clinical approach. For highly anxious children or those requiring extensive treatment, we offer conscious sedation options to keep the appointment calm and comfortable.
Can I get Invisalign and restorative work at the same office?
Yes, our multidisciplinary team coordinates orthodontic and restorative work without outside referrals. We use our iTero digital scanner to map your entire bite, allowing our cosmetic dentists and periodontists to plan crowns, veneers, or dental implants in alignment with your Invisalign treatment. If you live closer to our second location, you can coordinate this care through our Clarksburg practice as well.
