Your Main Line Dentist is your Devon, Pennsylvania dental office for Invisalign clear braces. Invisalign provides the state-of-the-art orthodontic system, straightening teeth using a series of durable, yet soft, nearly invisible, clear plastic aligners. To create that straight and attractive smile you've always wanted, Invisalign aligners gradually adjust the position and alignment of teeth.
We work with you to devise a program that will keep your natural teeth and the supporting structures clean and healthy, to prevent diseases or conditions from starting, progressing, or returning. The core of this program starts with you, at home, maintaining a balanced diet and following good oral hygiene practices.
ARESTIN is an effective antibiotic treatment that comes in powder form. This powder is easily placed inside infected periodontal pockets just after the dental professional finishes the scaling and root planing (SRP) procedure. We feature digital radiography in our practice. Instead of the old films, we can take an x-ray picture of your teeth that goes immediately into the computer for viewing by both you and Dr. Jankiewicz.
For your convenience we accept Visa, MasterCard, American Express, and Discover. We deliver the finest care at the most reasonable cost to our patients, therefore payment is due at the time service is rendered unless other arrangements have been made in advance. If you have questions regarding your account, please contact us at (610) 254-9575.

Everyone here is so sweet. They did everything to help me feel comfortable, including having someone hold my hand while I got shots to be numbed. I have greatly appreciated the patience and care from everyone I've met at this office. Definitely would recommend!!

Changed dentist offices years ago. Out of the blue, the office manager, or wherever she is, calls and makes an appointment with my wife. She mistakenly set the appointment at the time of the initial call. When the reminder call came in, she wanted to cancel as it was a misunderstanding and she wouldn’t be attending. Apparently the appointment was rescheduled and not cancelled.
Fast forward to when the reminder call comes in to my phone and not my wife’s. The woman was totally rude and unprofessional while I explained to her what was going on. She repeatedly tried to argue with me as to why

Dr. J's approach to dentistry is all clinical, combined with a deep interest and care for the patient and his / her life experiences. It is an absolute joy to see her and her support staff; this is not the usual feeling when dental work is necessary. She is calm, explains procedures in lay terms and she follows up, She is a unique dentist and individual/

I have been going to Dr Jankiewicz for about 10 years now, and am very happy with the practice. The office staff is great, always friendly and accommodating. I could not be happier with the quality of care and have recommended Donna to many friends of mine.

Not a big fan of going to the dentist, had an emergency with a broken tooth that had become infected. Called the office and the response was extremely caring and they were able to get me in the next morning. Dr. Jankiewicz is very professional,knowledgeable, very caring to my need of not being comfortable in any dentist office. Throughout the procedure which took over an hour I never felt any discomfort, afterward I had no pain at all. I would give Dr. Jankiewicz 5plus stars, and by the way guys she is easy to look at.
