A Message From Our Dentist

Dear Patients,

I am honored to have the opportunity to introduce myself to my new family of patients!

My name is Dr. Gagan Sandhu, DDS, and I have taken over the office of Dr. David M. Petti, DMD. In order for you to get to know me better, I would like to tell you a little about myself. I graduated from SJM Dental College in 2008 with a B.D.S. degree. I then continued my education and graduated from New York University College of Dentistry in 2014 with a D.D.S degree. After finishing my education, I moved to Monroeville with my wife Kiran and our daughter Amber. My wife and I celebrated our 8th wedding anniversary this March, and we have a very energetic and bright four year old daughter. We enjoy traveling, spending time with our family and friends, and Pittsburgh sports. 

Go Steelers!

After an extensive search for someone to take over his dental practice, I am honored Dr. Petti chose me to carry on his legacy. I am naming the practice Smiles Forever Family Dentistry, PLLC. During this transition and going forward, I am dedicated to making you feel as comfortable as possible. I prefer a gentle approach to treatment consisting of a delicate balance between modern techniques and equipment combined with a solid foundation in traditional treatment. 

During this transition the staff will remain unchanged as well as the office hours so that we can continue to accommodate your dental needs. I have and I will continue to log hours out of continuing professional education in order to fulfill your cosmetic, implant, and general dentistry needs. 

Smiles Forever Family Dentistry is here to help you feel and look your best through quality dental care. I look forward to meeting and serving each of you very soon!


Dr. Sandhu
