Meet Dr. Carroll

South Carolina’s Top Invisalign Orthodontist

Dr. Marshall Carroll is one of South Carolina’s renowned Invisalign orthodontists and a leading expert in transforming smiles. With a passion for creating beautiful and confident smiles, he combines extensive experience, a personalized approach, and state-of-the-art techniques to provide exceptional orthodontic care tailored to each patient’s unique needs.

Smiles By Design

Confident Smiles Need More Than Just “Straight” Teeth.

Smile Arc

Natural, aesthetic smiles tend to follow the contour of the lips. Although many orthodontists are obsessed with perfectly straight teeth, that’s actually not the secret to a better smile. Instead, we’ll make it so the bottom edge of your upper teeth matches the natural curve of your mouth.

Smile VME

Smile VME gets rid of that “Gummy Smile” and shifts the bite into the correct position to make the gums appear less prominent.

Smile width

Studies show that the wider your smile, the better. While we’re trying to show off as much of your individual teeth as possible, we’re also maximizing the number of teeth that are visible when you smile—from front to back.

Early Evaluation

At Carroll Orthodontics, we recommend that all children be evaluated at age 7, but this does not mean your child will need braces in second grade or even in the future. And you don’t need a referral by a dentist to take advantage of this free evaluation.

Invisalign
Invisalign is a series of removable and customized aligners that gradually shift your teeth into the desired positions. The aligners are worn like mouth guards over your teeth and are virtually invisible to the naked eye.

Orthodontic services for children, teens & adults!

While Carroll Orthodontics are recognized experts in caring for teens and adults, we also offer early evaluation for children, which we recommend at the age of seven. Unlike most orthodontic offices, we don’t require referral by a dentist and we offer the evaluation at absolutely no cost.

We had our first visit on Tuesday. I really felt comfortable with everyone at the office. I don’t think I laughed so much. I wasn’t worried the whole time. Everyone made me feel very comfortable. Plus I got ICE CREAM!!! The best part!!!

Great service. I have never met a staff so sweet and friendly. Dr. Carroll does a wonderful job. Just a few weeks after getting my braces put on.. I began to see changes!! Love them all!!

Just got my braces off and couldn’t be happier! I struggled with crooked teeth my whole life and finally feel good about my smile! Dr Carroll and team were very kind and supportive the whole time!

They are so quick! You come in, sit down, and in just a couple of minutes, your name is called. They do their thing, and you’re out of there in no time! Everyone is so friendly and always smiling (lovely teeth), you just want to hug them (well maybe not). I love Carroll Orthodontics!
