Better Cosmetic Restorative Results, Same Appointment Time, with Dr. Susan McMahon

Ask a room of general dentists which procedure they least enjoy, and a lot of hands go up for the anterior Class IV. It looks flat when you finish, and you catch the fracture line the second the patient stands up. Dr. Susan McMahon, an AACD-accredited cosmetic dentist in Pittsburgh, sees that dread as a training problem rather than a talent problem.

When she joined me on the Dental Slang Podcast, the line that stayed with me was a simple one: the anterior work we all admire on social media comes from a system, and a system can be taught. Dr. McMahon teaches general dentists restorative skills well past the posterior Class II. She is blunt that most of them are closer than they think, and that what they are missing is a sequence of steps to follow.

Over the hour, we covered where the chair time actually goes, which materials have shortened the learning curve, why younger patients are where conservative esthetics pays off, and how she applies the same systematic thinking to the consult itself. If you have ever avoided a Class IV because you were not sure it would look right, this is where I would start.

Inside This Episode

1. High-end esthetics is a skill set you can learn and teach

Dr. McMahon's central claim is that beautiful anterior restorations are repeatable. She does not treat high-end esthetics as a gift a few clinicians are born with. She treats it as a skill you can learn and then hand to someone else. In her words, a beautiful restoration can be built predictably and simply, without turning a single Class IV into a two- or three-hour ordeal.

2. A system removes time instead of adding it

The objection she hears most is time, and she agrees that no insurance-based practice can add two hours to a restorative appointment. Her answer is that a systematic approach takes out the guesswork that was already costing you minutes. If you can do a Class III in 30 minutes now, she says, you can do a beautiful Class III in the same 30 minutes, one that does not turn gray, does not leave a black triangle, and does not lose its sheen a month later. The Class IV follows the same logic: knowing the exact sequence is what separates a flat restoration with a visible fracture line from one the patient stands up and thanks you for. She frames this as finesse. You keep most of your materials and your schedule. What changes is how you layer, and that you layer the same way every time.

3. Diastema closure and black triangles are the biggest wins

Diastema closure and black-triangle correction are where Dr. McMahon sees the most return in younger patients. By her estimate, black triangles show up in as many as 40 percent of clear-aligner cases, which means most practices are already seeing the problem whether or not they treat it.

4. The materials finally caught up

Part of why this is teachable now is that materials do more of the work than they used to. Dr. McMahon points to single-shade composites that polish well and hold up, no-prep veneers for cases the orthodontist has set up well, and a menu of enamel surface treatments, from microabrasion to resin infiltration to whitening used in combination. Add chairside 3D printing, and a learning curve that used to run 20 years has gotten a lot shorter.

This is where my pediatric side leans in. I see the same teenagers she does, finishing orthodontics unhappy with a lateral incisor or a bit of spacing. Bonding, enamel treatments, and no-prep work let us address that concern without committing a young patient to anything aggressive, and Dr. McMahon has built a real referral base on exactly that idea.

5. The smile consult is a system too

Every patient enters her practice through what she calls a smile consult, and it starts with photography. She never asks a patient what they dislike about their teeth, because the question puts people on the spot. She takes photos and reviews them with the patient instead, and that opens the conversation on its own. None of it requires a dedicated closing room. Her consults happen in a regular operatory with a piece of black felt on the wall as the studio. A face scanner and an intraoral scan gather the clinical picture, but the knee-to-knee conversation in the first few minutes is the part she values most.

Key Takeaways

• A beautiful Class III or Class IV fits in the chair time you already schedule when you follow the same layering sequence every time.
• Diastema closure and black-triangle correction offer the biggest esthetic wins in younger patients, and Dr. McMahon estimates black triangles appear in up to 40 percent of clear-aligner cases.
• Single-shade composites, no-prep veneers, enamel surface treatments, and chairside 3D printing have shortened the learning curve for anterior esthetics considerably.
• Teenagers finishing orthodontics are well served by conservative options: bonding, microabrasion, resin infiltration, whitening, and no-prep work.
• Opening a consult by reviewing photos with the patient works better than asking what they dislike, and it needs nothing more than an operatory and a piece of black felt.
