Dr. Alexandra K. Greco was born and raised in the suburbs of Philadelphia. She attended the Agnes Irwin School and received her BA from Georgetown University where she majored in French with a pre-dental concentration. She earned her Doctor of Dental Surgery (D.D.S.) degree at Columbia University College of Dental Medicine. She then returned to Philadelphia to receive her specialty certificate in Orthodontics and Dentofacial Orthopedics from the University of Pennsylvania School of Dental Medicine.
While at the University of Pennsylvania, Dr. Alexandra was trained in many different forms of orthodontic therapy including traditional orthodontic correction, Invisalign treatment, 3 dimensional imaging and scanning techniques and collaboration in treatment of patients requiring complex jaw surgery. She also completed a rotation in craniofacial orthodontics at the Childrens Hospital of Philadelphia, in which orthodontists collaborate with other medical specialists to treat patients with clefts and other genetic facial abnormalities.
When Dr. Alexandra isnt helping patients achieve the smile they deserve, she enjoys running along the Schuylkill River Trail, cooking classic recipes from tattered family cookbooks and new wave food blogs alike and spending time with friends and family. In the summertime, her favorite place to be is on the beach at Cape May.
Dr. Alexandra is thrilled to return to her roots and join her father in practice. She shares the same emphasis on excellence and compassionate treatment that has made her father successful for more than three decades.
Braces are usually custom-made and are prescribed and designed by the orthodontist according to the problem being treated. Other orthopedic appliances are designed to correct jaw-growth problems. These appliances, which include headgear, bionator, Herbst and maxillary expansion appliances, use carefully directed forces to guide the growth and development of jaws in children and/or teenagers.
Todays braces are generally less noticeable than their predecessors: a metal band with a bracket (the part of the braces that hold the wire) placed around each tooth. Today, the front teeth typically have only the bracket bonded directly to the tooth (instead of surrounding the tooth). This greatly diminishes the old characteristic tin grin.
Generally, those who wear braces need to practice good oral hygiene in much the same way as those who dont. Of course, wearing braces creates unique problems. For example, avoid hard and sticky foods. Dont chew on pens, pencils or fingernails because chewing on hard things can damage the braces, almost ensuring longer-than-needed treatment times and cost. After application of braces, your orthodontist will show you how best to care for your teeth, gums and braces. This includes tips on how often to brush, how often to floss, and, if necessary, other cleaning aids that might help you maintain good dental health.
Overall, orthodontic discomfort is short-lived and easily managed. Most people have some discomfort after their braces are first put on or when adjusted during treatment. After the braces are on, teeth may become sore and may be tender to biting pressures for three to five days. The lips, cheeks and tongue may also become irritated for one to two weeks as they toughen and become accustomed to the surface of the braces.
Playing wind or brass instruments, such as the trumpet, will clearly require some adaptation to braces. With practice and a period of adjustment, braces typically do not interfere with the playing of musical instruments.
Retainers are needed after orthodontic treatment and removal of braces because the teeth can shift out of position if they are not stabilized. Retainers are designed to hold teeth in their corrected, ideal positions until the bones and gums adapt to the treatment changes. Wearing retainers exactly as instructed is the best insurance that the treatment improvements last for a lifetime.
What is a space maintainer? Baby molar teeth, also known as primary molar teeth, hold needed space for permanent teeth that will come in later. When a baby molar tooth is lost, an orthodontic device with a fixed wire is usually put between teeth to hold the space for the permanent tooth, which will come in later.

From start to finish, this was a five star experience. My year long Invisalign was virtually painless and I am thrilled with the outcome!

Had an amazing experience here! The staff is incredibly nice and knowledgeable. The wait times were always short and I was out the door and back to work quickly. The flexibility of the two locations was also very helpful and I was able to use which ever made the most sense for my schedule.

My daughter's retainer was broken, Dr Alexandra made a new one that only needs to be worn at night! She is amazing, and explained everything she was going to do and reason why. Already recommended her to my friends. :-)

Dr. Alexandra Greco picked up my Invisalign case after I moved to Philly and after Covid stopped my progress with my first orthodontist in Pittsburgh. She gave me a fair price and I dont know if orthodontists have "bedside manner" but hers is top notch! She is very friendly and I loved how she explained everything to me in detail in a way I could understand, taking the time to answer all of my questions. I truly felt like I was her only patient, as she was attentive and responded to any of my inquiries quickly. I dont know how many assistants she has but the one I always saw was also very personable, professional and helpful. They were also thorough during every checkup and procedure and Dr. Greco even fixed a couple of things for me that I would have to go to a dentist for. I think my case was a tough one and she did everything in her power to give me a beautiful smile and correct my bite and I am very satisfied! She even corrected the mistakes of my previous orthodontist, who I found out was not very good at her job and was not explaining everything to me. I definitely recommend Dr. Alexandra Greco!

My permanent retainer broke inside my mouth leaving a half inch steel spike cutting into the bottom of my tongue which was very painful. I live downtown and called literally every emergency dentist, orthodontist, and regular dentist in Philadelphia with no avail for a same-day appt. (One office quoted me 300$ to cut the spike next week). Desperate, I broadened the search to the Main Line and found Dr. Greco's office. The lovely receptionist Annabelle was able to fit me in that morning. The procedure took 5 mins and the entire staff was above and beyond professional and so, so nice. I was so grateful that Dr. Greco's office would make time out for someone who was not a previous patient that I would've given them everything in my wallet but they did it free of charge. I've learned not to expect anything from anyone, so when someone does something really nice and doesn't expect anything in return I'm taken aback. I was so moved by the whole experience that it brought me to tears. I will not forget the kindness, care, and generosity that I was shown by Dr. Greco and his team. I don't think I'll need any more orthodontic work but I would recommend Dr. Greco to anyone and everyone who does. Wonderful people. Thank you so much!!!

Dr. Greco is the best! My permanent retainer broke off after 15 years of wear. I was new to the area and had no idea where to turn. I'm so glad I found Greco Orthodontics! Dr. Alexandra was so sweet and easy to talk to and made getting my new retainer a breeze. I was in and out in under an hour, no pain! Thanks again!

I've been going to Greco Oerhtodontics for over 13 years for braces, check-ups and retainer alterations. I love the convenience of having the center city & Admore locations, along with the most friendly staff you could ask for. Dr. Greco is patient and kind and always listens to your questions and concerns thoroughly. You never feel rushed while inquiring about various treatment options. Thank you for keeping my teeth healthy and straight these past 13 years !

As an adult, my teeth had shifted to the point where it really bothered me. I had braces when I was younger but I didn't wear my retainer, and over time the shifting progressively got worse. My dentist, Kaminsky Dental, referred me to Dr. Peter Greco. When I met Dr. Peter, he immediately made me feel comfortable and confident with his options of treatment. He's incredibly kind and smart and a joy to chat with. Partial braces for 6-8 months - wasn't thrilled to have braces as an adult but I wanted to have straight teeth - so I did it! Once treatment started, I also got to meet Dr. Alexandra who also treated me. And she is just as fabulous as her Dad!! Incredibly kind and fun to talk to, but also an excellent orthodontist and super smart! 2020 happened and unfortunately my treatment was paused for about 3 months during the shutdown. We finished out my treatment recently, so I had continued treatment during the pandemic and their office could not have been more prepared, and really made you feel safe. They took all the necessary precautions to make their office safe for their patients. The staff is also amazing!! I could not be more thrilled with my treatment outcome - thank you so much Dr. Peter, Dr. Alexandra and your wonderful team!

Dr. Alexandra Greco is an excellent practitioner. She is a warm and kind person which gives her amazing "bedside" manner when working with her patients, but she's also incredibly smart and makes the right medical decisions. What a great balance that's hard to find. Highly recommend this practice for your orthodontist needs!

I was the luckiest person to be referred to Dr Greco's' office after an accident where my teeth got twisted. Two years of their professional excellence with attention to every detail, frequent office visits to check and adjust, topped by absolutely wonderful patient care and communication, my smile is restored! I want to return the service to others: I would recommend Greco Orthodontists in a heartbeat if you are looking for a happy smile on your face!

Being new in the area we were happy to find Dr Greco. Dr Greco followed my daughter for a few years as she had to wear braces. We experienced fantastic service throughout in an easy to access location. The offices of Dr Greco, his staff - all of them from the reception to his assistants and his daughter Dr Alexandra - provided excellent service. We would recommend Dr Greco to all.
