Board-Certified Orthodontist in Simpsonville, SC

To achieve certification by the American Board of Orthodontics (ABO), orthodontists must not only have significant knowledge and expertise – they must also demonstrate that they follow the highest standard of care by presenting consistent, high-quality orthodontic results from their own patients. Only 1 in 3 orthodontists succeed in meeting the stringent standards of ABO Certification, which Dr. Marshall achieved in 2013.

Even after receiving ABO Certification, Dr. Marshall strives to be the orthodontist in Simpsonville, SC that not only continually improves upon his own skills and orthodontic knowledge, but also those of his entire orthodontic team. This ensures that our orthodontic office has the experience and dedication to properly diagnose your case, expertly recommend the best-suited course of orthodontic treatment, and ensure that you get on the right path to your happiest and healthiest smile.

When it comes to the health and esthetics of your smile, working with an orthodontic team led by a Board-Certified Orthodontist is key!

Superior Sterilization

At Marshall Orthodontics, providing happy, healthy smiles is our goal. In order to accomplish this, we take the overall health of our patients very seriously. That’s why we hold our office environment and equipment to the highest sterilization standards and ensure everything is meticulously cleaned after every appointment. Non-disposable items (ie orthodontic tools/instruments) are sterilized in a high pressure and high heat sterilization machine. Disposable items such as suction tips, air/water syringe tips, and cotton rolls are always discarded and never reused. Our clinical team members use protective equipment such as surgical masks and non-latex gloves. Additionally, modifications have been made to our equipment that minimizes and nearly eliminates air and water spray that could potentially create aerosol.

When you visit our orthodontic office, you can rest assured that everything in our office meets the highest level of sterilization standards.

Advanced Technology for Orthodontic Care

Orthodontics has become a cutting-edge discipline, and all these innovations mean that we can offer patients like you the very best the industry has to offer. Here are just a few of the state-of-the-art diagnosis and treatment options you can take advantage of at Marshall Orthodontics:

3D Digital Scans with the Itero Element Digital Scanner – The Itero Element digital scanner replaces the old messy method for taking teeth impressions. You don’t need to hold a bad-tasting and uncomfortable putty tray in your mouth anymore! Thanks to the Itero Element, your diagnostic experience is healthier, more comfortable, and more reliable!

Discreet Teeth Straightening with Invisalign – The revolutionary development of Invisalign clear aligners has made it easy to straighten your teeth without disrupting your lifestyle. Invisalign’s aligners are removable, which means you can eat and drink anything you want without worrying about damaging your orthodontic appliance. This also means you can brush and floss normally, and you don’t need to worry about food getting caught in braces. Best of all, because Invisalign aligners are made from specialized clear plastic, you can straighten your teeth without your friends or coworkers noticing!

3D X-Rays with Cone Beam Technology – To ensure that the plan you and Dr. Marshall develop for your orthodontic treatment is the best one for your needs, a 3D x-ray may be needed to examine the exact positioning of one or more teeth in your jaws. Some orthodontic offices will refer to other dental specialists for these advanced 3D x-rays, but at Marshall Orthodontics, we take them in-house at no additional charge.

To see our state-of-the-art technology and treatment options up close, call Marshall Orthodontics at 864.249.4388 and schedule an appointment today. You’re going to love what you see!

Two Sets of Retainers Included

Transforming your teeth into a smile you’re proud to show off starts in the office. However, it’s important to remember that you will need to wear a retainer after treatment to keep your smile looking its best. We want you to keep your beautiful smile! That’s why you can count on extra support from Marshall Orthodontics, with two (2) sets of retainers INCLUDED with braces or Invisalign treatment.

This means that if one of your retainers is broken or lost, you’ll be equipped with a backup retainer to ensure that your teeth don’t shift in the time that it takes for you to have the broken or lost one replaced. This is just another way that Dr. William Marshall goes above and beyond as the best orthodontist in Simpsonville, SC.

Same-Day Starts for Orthodontic Treatment

Dr. Marshall and our team know your time is precious and important. With work, school, and extracurricular activities, finding time in your busy schedule for orthodontic appointments can sometimes be difficult. That’s why we are happy to offer patients the option to start treatment on the same day as your initial exam and consultation if certain conditions are met.

When scheduling your Complimentary Marshall Orthodontics Consultation, please inform our team that you are looking to get started with braces or Invisalign on that same day as your first visit, and we’ll be sure to share the next steps to make this possible.
