Frequently Asked Questions
Where can I find an eco-friendly dentist in Philadelphia?
Dentists on Washington is Philadelphia’s first eco-friendly dental practice, located near Center City and Bella Vista. We utilize 100% wind-powered electricity, digital X-rays to reduce radiation, and a waterless vacuum system to save 360 gallons of water daily.
How much does a dental exam cost in Philadelphia without insurance?
We offer a comprehensive Dental Exam for $149. This evaluation includes an overall oral hygiene assessment, decay and gum disease risk evaluation, TMJ screening, and digital X-rays if necessary to ensure affordable dental care that Philadelphia residents can rely on.
What should I do if I need emergency dental care in Philadelphia?
If you experience severe tooth pain or dental trauma, our office provides Emergency Dental Care Services in Philadelphia. We offer Saturday appointments to ensure you receive urgent treatment when most traditional offices are closed.
Are BPA-free composite fillings available in Philadelphia?
Yes, Dentists on Washington provides BPA-free composite fillings. These tooth-colored restorations do not contain bisphenol A, aligning with our commitment to biocompatible materials and green dentistry.
How does Invisalign straighten teeth without braces?
Invisalign Treatment uses a series of clear, removable aligners to gradually shift teeth into position. This alternative to traditional braces offers a nearly invisible look and easier maintenance for patients in Philadelphia and Washington Crossing.
What makes a dental practice "green" or sustainable?
A green dental office like ours reduces environmental impact through several initiatives:
- Using steam sterilization instead of harsh chemicals.
- Implementing Amalgam Separators to keep mercury out of local waterways.
- Transitioning to 100% digital charts and E-claims to eliminate paper waste.
Is a root canal procedure painful?
Modern endodontic technology has made the Root Canal procedure much more comfortable. Our doctors focus on patient comfort and use advanced tools to eliminate infection while preserving your natural tooth structure.
What are the benefits of digital X-rays over traditional ones?
Digital X-rays offer significantly reduced radiation exposure compared to film. Additionally, they eliminate the need for caustic developing chemicals and hazardous waste, making them a cornerstone of Preventive Dental Care.
Which is better for tooth replacement: dental bridges or implants?
The choice between Dental Bridges and implants depends on your bone density and oral health goals. Implants are a permanent solution that doesn’t affect adjacent teeth, while bridges are a reliable, non-surgical option for filling gaps.
How can I manage gum disease effectively?
We offer specialized Periodontal Disease Treatment to address symptoms like bleeding gums and bone loss. Early intervention through deep cleanings (scaling and root planing) is essential for maintaining long-term oral health.
What technology is used for oral cancer screenings?
Our practice utilizes the VELscope® Vx Enhanced Oral Assessment System. This handheld device helps Dr. Duyen Ngo and Dr. William Costello visualize tissue abnormalities that might not be visible to the naked eye.
Do Dentists On Washington offer Saturday appointments?
Yes, we understand our patients have busy schedules. We offer Saturday hours at our Philadelphia location to ensure you can access Other Dental Services without missing work or school.
How do I choose between dentures and dental implants?
Dentures are an excellent, cost-effective way to replace multiple missing teeth. However, dental implants offer more stability and prevent bone loss. We recommend a consultation at our Philadelphia or Washington Crossing locations to determine the best fit for your lifestyle.
