Very few people have naturally straight teeth. Straight teeth look brighter because they do not cast shadows and because they are easier to clean and bleach. Straight teeth also function better and are easier for the general dentist or dental specialist to maintain. Over a period of time, your teeth will shift if constant, gentle pressure is applied.
Invisalign and Invisible Braces by Philadelphia, PA and Lawrenceville, NJ Orthodontists Drs. Roberts & de Marsche. Imagine getting a perfect smile without the prolonged period of sharp metal and wires in your mouth. That's what invisible braces deliver. Invisible braces and "Invisalign" braces are a brand-new trend in tooth alignment and straightening. For the average patient, it means freedom from the negative aspects of wearing braces.

Dr. Roberts and the entire staff are great. I love the results of my Invisalign treatment and my year-long treatment flew by! I had to reschedule appointments last minute a few times and Lisa was very understanding and accommodating. I highly recommend this office for any of your orthodontic needs.

I highly recommend Doctor Roberts! At the age of 48 I decided I wanted to stop covering my smile. I was referred by a lady who had braces on at my hair salon and set up a consultation visit. I was sold! They thoroughly explained my options, explained the process, showed me before and after shots of previous patients. After looking at the pictures, I said they are miracle workers.

I am scared to death of the dentist so this was a big step. They made me fill at ease. The staff is professional, friendly, helpful and funny. Thank you, Dr. Roberts, Lisa, Judy and Kathy for a great experience!

I am soo glad I was referred to Dr. Roberts' office! Upon my arrival I was kindly greeted by Lisa who has such a sweet spirit about her, I felt right at home. The office decor is clean and modern with a cozy atmosphere. They're is even a game room complete with arcade games for children. impressive! At my consultation Dr. Roberts explained everything thoroughly and had me excited for my braces even though i went for invisalign (which were more expensive) he was more concerned about what's best for me as a patient and there was no pressure. Dr. Roberts is caring, kind & has a quirky sense of humor which has me laughing at every appt, he even introduced me to my new favorite eatery, Dizen Goff! Lastly, I had to return to the office atleast 7 times in the first month and it was never a problem for Judy nor Lisa to get me right in and assist me even when everyone in the office was away.

I never felt like I was a hindrance. Judy is the cool, outgoing, funny homegirl who doesn't hold back and I absolutely adore her! Overall, I love my Ortho and look forward to each visit. Keep up the great work guys! P.S. there's another assistant I can't think of her name right now but she's just as helpful and a sweetheart. just an awesome group of people who define "quality care"

I've had a great experience here so far. Everyone at the office is friendly and helpful. Dr. Roberts took the time to evaluate my teeth and have an in depth conversation about my alignment. I'm excited to see the results!

I went to Dr. Roberts in 2018 after a jaw surgery and just finished my treatment. Dr. Roberts is very professional and try to make you feel as comfortable as possible. All staffs are very friendly! Overall, I have a great experience and would recommend this place for anyone!
