“The doctors at CMOA have been treating my autistic nephew for several years. He can’t wait for his appointments. He asks many questions to the doctors, and they patiently answer all of them. I highly recommend this practice.”

A Trusted Orthodontist in Spencer

Dr. Gregory Livanos graduated with a Bachelor of Science from Fairleigh Dickenson University in Teaneck, New Jersey. He then received his Doctorate of Dental Surgery from the Fairleigh S. Dickinson Jr. School of Dental Hospital before completing a general practice residency at St. Clare’s Hospital in Schenectady, NY.

Dr. Livanos practiced general dentistry for six years in Saratoga Springs while maintaining a faculty appointment at St. Clare’s Hospital. He later received his Certificate in Orthodontics at Tufts University School of Dental Medicine. As a board-certified orthodontist, he became a Diplomate of the American Board of Orthodontics in 2005.

Dr. Lisa Giarrusso is affectionately known as a Triple Jumbo, a three-time graduate of Tufts University. She received her Bachelor of Science from Jackson College of Tufts in Medford. She then moved to the Boston Campus, completed her Doctorate of Dental Medicine, and finished her Certificate in Orthodontics two years later. After graduation, she joined the orthodontic faculty and has always remained affiliated with Tufts.

Dr. Giarrusso taught from 1992-2008 as an assistant clinical professor of orthodontics. She achieved board certification when she became a Diplomate of the American Board of Orthodontics in 1999. She has extensive experience treating children and adults and numerous patients who require orthognathic surgery in combination with their orthodontics.

Spencer Braces

Traditional braces are one of the most efficient orthodontic tools we have. They’re made of metal or ceramic brackets attached to the teeth, then connected by wires and tiny rubber bands or elastics.

These brackets, wires, and bands work together to apply the gentle pressure that will gradually move the teeth into the positions we want them to be in as long as you have regular adjustments at our Auburn, Spencer, or Worcester office.

Braces are an excellent choice for correcting complex tooth issues. Because they can sometimes work faster at aligning teeth and closing gaps than other treatments, the time you wear them is shorter than other options.

Braces don’t need some of the more complex technology or expensive equipment that newer treatments can. This means Worcester braces are a cost-effective orthodontic option.


Spencer Invisalign

Invisalign is incredibly popular with patients and orthodontists in Spencer and is the top alternative to traditional braces. Instead of brackets and bands, the Invisalign system uses a series of clear, removable aligners to gradually straighten your teeth.

Invisalign aligners are made of a comfortable plastic material and customized to fit snugly over your teeth. To keep your teeth moving in the direction you want them to, you’ll need to switch your invisible trays out for the next one in the series every one to two weeks as directed by your orthodontist.

The Invisalign system can only work if the recommended guidelines are followed exactly! Aligners should be worn 20-22 hours per day throughout treatment. If patients neglect to wear the aligners as directed, it can impede the results and also add time to the orthodontic process.

Invisalign is at its most efficient when correcting many of the most common orthodontic issues. For some complex cases, Invisalign may not be a good option. A consultation with Dr. Livanos, Dr. Giarrusso, or Dr. Kotin at Central Mass Orthodontics in Spencer will allow us to determine your eligibility for Invisalign.
