How to Do a Beautiful Class Four in the Same Time as a Regular Filling with Dr. Susan McMahon

What if you could do a beautiful class four in the same 30 minutes you’d spend on a regular filling? In this episode, Dr. Reza Ardalan sits down with Dr. Susan McMahon, an AACD-accredited restorative dentist out of Pittsburgh and one of the most recognized clinicians in the country. Susan is the founder of Smiles in the City, a fee-for-service restorative practice she built from the ground up after starting her career in a drill-fill-and-bill amalgam office.

The conversation takes a personal turn early when Susan tells the story of the $100,000 laser whitening system she signed up for without reading the contract — the moment her practice tipped from "what people need" to "what people want." From there, Reza and Susan go everywhere: why AACD accreditation rebuilds your eye, how she became a restorative referral source for teenagers and post-ortho cases, the conservative European mindset she picked up training in Italy, why diastema closure and class four restorations can be done predictably in the same time as a regular filling, and the tag-the-practice social media system that fills her chair.

A key part of the conversation lands at the end. Susan walks Reza through her upcoming online restorative course — five one-hour modules built for general dentists who want to elevate their everyday restorations without slowing down their day. Module one is the class four. Module two is the invisible class three (no gray, no lost sheen). Module three is her five-minute finish — the polish that puts surface anatomy back so composite reads as enamel instead of plastic. Module four is using provisionals as the prototype for final restorations. Module five covers her full enamel treatment toolkit — microabrasion, infiltration, whitening combinations. It's the first time she's put her actual restorative system online, and if you've ever felt the gap between what you see on social media and what you can actually produce in your operatory, this one is gold.
