About Our Office

Our Collingdale dentists are happy to welcome new patients and emergencies to our state-or-the art dental practice. Our friendly team of dental professionals offers comprehensive care for all your dental needs including, dental cleanings and polishing, tooth extractions, crowns and bridges, dentures, fillings, teeth whitening and veneers. We are here to make your smile with our convenient and affordable general, preventive, restorative and cosmetic dentistry.

Gentle Dental of Collingdale is conveniently located on MacDade Blvd. in Collingdale, Pennsylvania. We’ve been proud to be part of the Collingdale community for more than 15 years, and we’d love to welcome you and your family to our dental practice.

We accept most major dental insurance plans including Blue Cross and Blue Shield, Delta Dental PPO and Premier plans, United Concordia, Aetna, Ameritas, Assurant and Cigna dental insurance plans. This does not represent the complete list of dental insurance plans for which we are preferred providers. If your dental insurance plan is not listed here, please call us directly and we’ll be happy to speak with you about your individual dental plan and treatment needs.

No dental insurance? No Problem! Just ask about our in-house discount plan – an affordable alternative to dental insurance providing substantial savings on all your needed or elected dentistry. That’s right… unlike most dental insurance plans, you are able to use our discount dental plan to make elective, cosmetic dentistry more affordable. Call us to sign up today and begin saving on dental cleanings and x-rays, plus other dental treatments such as crowns, teeth whitening, veneers and bonding.

We are committed to finding financial solutions to fit your budget, by either helping you maximize your dental insurance benefits, offering you our in-house discount plan or assisting you with financing options.
