Dr. Sarah Kowalski, DDS.
Braintree Born. Braintree Proud.

I grew up in Braintree, and I know this community. My goal has always been simple: make the dentist a place people actually want to come back to. No judgment, no pressure — just honest, gentle care.

After graduating from Boston University School of Dental Medicine, I completed advanced training in cosmetic and restorative dentistry. I opened South Shore Smiles in 2008, and many of my original patients are still with us — now bringing their own kids in for their first visits.

We're a small practice by design. When you call us, you get a person. When you come in, Dr. K remembers your name. That's how it should be.

Appointment confirmed instantly. No voicemail. No callback the next morning.

Call to Hear It Yourself

Most patients don't realize it's AI until we tell them.

What South Shore Families Are Saying

4.9 stars across 280+ Google reviews. We let our patients do the talking.

"I've been terrified of dentists my whole life. Dr. K completely changed that. She's patient, explains everything, and there's zero judgment. I actually look forward to my appointments now. That says everything."

— Jennifer M., Braintree

"Called at 8pm when my son had a toothache. Their AI receptionist answered immediately, booked us for the next morning. I was honestly shocked — I expected voicemail. Great practice, great experience."

— Mark R., Quincy

"We bring our whole family — three kids ages 5 to 14. The hygienists are incredible with the little ones. Clean, modern office, always on time, and Dr. Kowalski genuinely cares. Five stars isn't enough."

— Lisa P., Weymouth

"Had a crown done here — same day with their CEREC technology. In and out in two hours with a permanent crown that looks completely natural. No temporary, no second visit. Incredible."

— Dan H., Braintree

"I switched dentists after 10 years and wish I'd done it sooner. Modern equipment, friendly staff, and Dr. K took real time to explain my treatment options. They take Delta Dental too. Highly recommend."

— Christine B., Braintree

"Started Invisalign six months ago — my teeth are already transformed. Dr. Kowalski is so thorough and the app makes tracking progress easy. Best investment I've made in myself in years."

— Amanda S., Cohasset
