A preventive program is a cooperative effort by the patient, dentist, and dental staff to preserve the natural dentition and supporting structures by preventing the onset, progress, and recurrence of dental diseases and conditions. Preventing dental disease starts at home with good oral hygiene and a balanced diet.

The drill (aka the 'handpiece') strikes fear into the hearts of many with its noise, vibration, and heat.

Excellent Practice. Everyone from the receptionist, to the nurse, to Dr. Belhaj, to the Dental Hygienist are first rate. They really are focused on the patient not just as a dollar sign. The dental hygienist was not only the most thorough I've ever had, but literally painless...not one tiny nick on the gums. My teeth look better than they have in 20 years. I'll be going back to them as long as my insurance will allow...you'd be smart to do the same.

I have severe periodontal. The doctors did a wonderful job at getting me on the path of recovery.
I used to be afraid of “the dentist” not the case at this dental office. No pain, lots to gain. Keep in mind that is a lengthy process and costly, but you will be in good caring hands.
5 stars to the lady at the front desk as well.

I had such a great experience here. The staff is exceptional and personable. The office is professional and pleasant. I had two painless extractions that went so smooth, I was in and out of there in no time. I recommend this to anyone who wants a fearless experience. They even explained my coverage to me and what options I had for payment. Love this place.

Marissa Cruz is terrific! She made my rather involved dental surgery comfortable and answered my many questions. I am a ninny about pain and Marissa made the procedure pain free and afterwards I was quite comfortable. I was very grateful for that because I was out of state shortly after the surgery. Marissa called me and responded to several of my questions as I was acclimating to my post surgery mouth! I felt completely supported and I will recommend Marissa to any of my friends who need periodontal care.

I was so nervous when my dentist said I had to have a gum surgery but after I had the consultation and met the doctor I was relieved. Dr. Cruz was the great she listened to me and I was relaxed and comfortable for the procedure. I recommend her to everyone I know who needs periodontal work.

Jonathan is an extraordinary periodontist and all-around fabulous person as well. There is no pain with his visits. And after each procedure, he calls you to make sure you are okay! Not only is he running two offices, but for years he taught at University of Pennsylvania, where he studied dentistry. When he graduated from
Penn, he had scored highest on both
parts of the National
exam. Jonathan had also worked at a military base, where he made dental diagnoses for returning personnel from
Iraq. Recognized by his peers, Jonathan has been voted best periodontist in Philadelphia for years. I highly
