Our registered dental hygienist, Amanda, has been with our practice for 13 years. In addition to working clinically for 18 years, she has been adjunct faculty at the Westmoreland County Community College for the last 8 years.

She has a Master's Degree in Adult and Community Education from IUP, as well as a Bachelor's Degree in Dental Hygiene Education from the University of Pittsburgh and an Associate's Degree in Dental Hygiene from the Westmoreland County Community College.In addition, she is a certified dental assistant, local anesthesia trained, and a public health dental hygiene practitioner.
Prevention and early detection are the key to avoiding tooth decay and gum disease. A good home regimen, in addition to regular cleanings and exams, can prevent many expensive dental treatments. Prevention starts with controlling plaque, a colorless bacteria that sticks to the surface of your teeth, and calculus, a harder mineral deposit.
Enhancing the smile's aesthetic appearance can lead to increased self-confidence, improved social skills, and even a more positive outlook on life. Modern cosmetic dentistry merges advanced technology with fine art, and can often produce amazing results in less time than you would expect. Customized trays are filled with a whitening gel and worn in the mouth for as little as 1 hour per day.
Almost everyone will experience tooth decay at some point in his or her life. Swift detection and correction of tooth decay can minimize the significant expenses and inconveniences associated with more serious problems caused by tooth decay. Restorative dentistry treats all phases of tooth decay, from simple cavity fillings to entire tooth replacements.
Crowns and conventional bridges or dentures may not be your only options when replacing missing teeth. Dental implants offer a smile that looks and feels very natural. Surgically placed below the gums over a series of appointments, implants fuse to the jawbone and serve as a base for individual replacement teeth, bridges or a denture.

Dr Liberati has been my dentist for many years! He and his staff are excellent at what they do, from the front desk to the dentist chair! Amanda has also been my favorite dental hygienist I’ve ever had! Thanks for always keeping my teeth in the best shape possible!

Dr Liberati has been my dentist for a very long time (over 25 years). He and his staff have always done a fantastic job. They are methodical and thoughtful in their procedures only doing what is necessary and thorough in their followthrough. I highly recommend both Mark and his hygienist], Amanda, to all who are searching for a dentist practice to provide solid oral care.

Best dentist that I've ever been to. Takes time and explains procedures and all options available for you. Does not pressure you into an option.

I had new insurance and a sudden toothache and woth the sweet office hours even in times of covid got an appointment in 2 days, and was quickly prescribed meds tp solve the problem. Major suggestion though, PLEASE PLEASE PLEASE get a voicemail service and maybe multiple phone lines. I would have used this dentest ages ago but when I first called ot was busy which made me think it was a bad number and closed office. Also, lots of reasons for phone tag and it is unhelpful to oftentimes get a busy signal when simply leaving a message woth the onfo would suffice. PLEASE UPDATE THE PHONE SYSTEM.

They are very nice, and Dr. Liberati made my dental experience pleasant and not painful. I appreciate the fact that they are taking extra precautions to guard against COVID-19.

I was drawn to Dr. Liberati's office because of his superior digital imaging techniques and nearly pain-free injection process using a vibrational tool. He's a calm, confident and caring man - a total professional with a patient and attendant staff of experienced ladies.

I saw Dr. Liberati again after not seeing him since 2011 (due to insurance changes) and not much has changed. They still have great employees who make your visit more enjoyable!

They also have flexible hours, which is rare for medical/dental offices. They have availability all the way to 9pm some days for those who work during standard business hours.

Call your insurance to see if Dr. Liberati is in network and schedule your cleaning!

There is simply no better dentist office in Pittsburgh than Dr. Liberati's! From the caring and professional staff to the amazing work Dr. Liberati does, this is a top notch dental office offering flexible hours and individualized attention. Willing to work with anxious patients and provide gentle routine teeth cleanings. Will drive out of my way to go here!

Let me start off by saying that I had a REALLY REALLY bad experience with a dentist. Because of that experience I didn't go to a dentist for several years. Then I met Dr Liberati. He promised he would be gentle with me. I made an appointment. My anxiety was through the roof. My husband called and told them that if I had to wait in the lobby that I would leave because of my anxiety of seeing a dentist. They took me straight back. Dr Liberati was extremely gentle with me. My mouth/teeth were a hot mess and each visit Dt Liberati was very kind and gentle. I cannot say enough good things about
