Providing Adult and Youth Braces in Philadelphia and New Jersey

Invisalign Elite Preferred Provider in Center City and Lawrenceville

Offering Invisalign for Adults and Invisalign Teen

Orthodontics are not one size fits all. Nor, is an orthodontist. In fact, many patients are surprised to discover they are good candidates for multiple types of orthodontist treatment. Teens may expect that they are destined for the metal brackets and wires of traditional braces but Invisalign Teen could be a viable option. Adults may shy away from braces entirely when subtle solutions are available to straighten their teeth without interrupting their life.

Drs. Roberts & de Marsche are an established team of orthodontist experts serving the Philadelphia area, with two conveniently located offices in Center City and Lawrenceville, NJ.

Youth Braces

Braces and teenagers are a common duo, but the orthodontia a teen receives will vary depending on the positioning of their teeth. Traditional metal braces are used to correct overbites, underbites, crossbites, overcrowding, and large gaps. But, in many cases, and depending on the severity of the misalignment, Invisalign Teen can be used to correct these conditions too.

General dentists refer many adolescent patients to our offices, where they undergo a thorough exam by Dr. William Roberts or Dr. Tanja de Marsche. From there, appropriate treatments are recommended, decisions are made, and we begin the path to creating a beautiful, aligned, comfortable smile.

We understand that teens want to draw the least amount of attention to their teeth as possible when they’re wearing braces, so we make every accommodation to give our youngest patients confidence in their appearance while their teeth are being corrected. Braces don’t have to be a painful rite of passage.

Adult Braces

Getting braces at any age is a big deal, but making this decision as an adult is even more significant. You have a family, a career, an established social network. You have people who know how you look and don’t expect you to change. And the last thing you want to do is feel like you are a metal mouth past the age of 20.

Traditional braces are much smaller and unobtrusive than decades ago, but the idea of obvious braces is unappealing to most adults. Invisalign braces are the popular option among adult orthodontic patients because the aligners are practically invisible, the treatment requires fewer visits to the orthodontist than metal braces, and you still have the freedom to eat whatever you want without restrictions. There are plenty of Invisalign rules to follow but, overall, adults appreciate the flexibility of these under-the-radar braces and the faster treatment time.

Invisalign Braces from an Invisalign Elite Preferred Provider

The “Elite Preferred Provider” title is important when it comes to Invisalign providers. This innovative technique of straightening teeth using nearly invisible aligners is a specialty. Not every orthodontist is qualified to provide Invisalign.

When you want to straighten your teeth and you are interested in Invisalign, choose a dentist who has experience and skill. The Elite designation granted to Roberts & de Marsche is evidence of a dedicated, experienced, orthodontic practice. We have successfully treated over 2,000 Invisalign patients.

Along with Invisalign for adults, Invisalign Teen is available. While some parents may assume their adolescent may not be up for the responsibility of Invisalign, this orthodontic treatment is often so appealing to teens that they are some of the most dedicated patients. They follow their treatment plan to the letter, ensuring that their teeth are straightened the right way at the right time, for a shorter overall orthodontic experience.

Saturday Appointments

Drs. Roberts & de Marsche are dedicated to making orthodontic treatment accessible and convenient to every patient. If it is difficult for you to take time off work or take your child out of school for appointments, our offices have Saturday hours.

Our staff is friendly and works hard to provide a comfortable, gentle, orthodontic experience from start to finish. After all, braces of any kind take time. We will get to know you and you will get to know us and, together we will develop relationships and establish trust. We are dedicated to making every individual’s braces journey as pleasant and easy as possible.

Take the path to a straight smile. Schedule your consultation at Roberts & de Marsche’s Center City or Lawrenceville, NJ, office.

Patient Reviews

  • Drs. Roberts and de Marsche are extremely experienced in their practice and its evident in their work. I was very excited about their Saturday hours in Lawrenceville. I have been able to make the commute from NYC easily as necessary. +1 for adult Invisalign!

  • SO GOOD I HAD TO WRITE IT IN CAPS! FINE PLACE! EVERYONE REALLY CARES ABOUT THE PATIENT – RECEPTIONISTS ARE AWESOME!

  • I’m so glad I went with Dr. Roberts! We’re finishing up my adult treatment and I am very happy with my smile. Dr. Roberts is skilled, personable, and truly cares about making sure his patients leave with nothing less than a stellar smile! As a patient, it can be really difficult choosing the right orthodontist for you when you don’t know anything about orthodontics (like me). I consulted with several doctors, read their online reviews, and looked at photos of their work, but in the end I still didn’t feel confident that I could choose the best treatment plan for me (was given vastly different treatments). I chose Dr. Roberts because I liked his work and because I felt very comfortable with him (and his staff) during my consultation. He explained my proposed plan to me and he and his staff didn’t mind answering my millions of questions when I called back later after doing more research. About a year after I started my treatment, I moved cross-country. This drastically slowed down my treatment because I couldn’t schedule regular appointments. Earlier this year when I went back out West after the holidays, I bit into something really hard and caused damage to my braces. It was an easy fix, but I couldn’t make it back for another six months. By the time I saw Dr. Roberts again, the problem was much worse than it would have been if I had just seen him soon after it happened. This added about half a year’s visits (with regular appointments) to my treatment. It was no problem at all and Dr. Roberts is taking care of it. I can’t imagine how much extra work he has had to put into my braces because of my insanely irregular visits. I’ll bet we could’ve ended my treatment sooner if he wanted (I’ve been seeing him for 3+ years), but Dr. Roberts won’t get these things off me until he’s sure I have my best smile. I don’t know if other doctors would have been as pleasantly accommodating as he’s been! (I’d even left some of my consultations feeling rushed and inconvenient.) His office is friendly, clean, and there’s always good music playing (and a movie for kids in the waiting area). Would recommend!

  • I just finished my invisaline treatment by Dr. Roberts. He did a fantastic job. Also, His staff was accommodating and very friendly. I would have no problem recommending Dr. Roberts to my friends and family. Thanks Again!

  • Excellent Service and Staff
