About Your Doctor
Dr. Michaelangelo Aust
DDS · Master of Oral Implantology · Fellow, California Implant Institute
I grew up believing that dentistry was about more than fixing teeth. It's about restoring the way people move through the world — the confidence to laugh out loud, to introduce yourself with a handshake and a smile, to eat whatever you want at a dinner table without thinking twice. That belief is what led me to over 20 years of practice, more than 10,000 patients treated, and an approach to dentistry that's intensely personal.

His Story
Doctor. Educator. Builder.
I grew up believing that dentistry was about more than fixing teeth. It's about restoring the way people move through the world — the confidence to laugh out loud, to introduce yourself with a handshake and a smile, to eat whatever you want at a dinner table without thinking twice. That belief is what led me to over 20 years of practice, more than 10,000 patients treated, and an approach to dentistry that's intensely personal.
I founded Advancements in Dental Care because I wanted every treatment decision to be made for the right reason: what's best for the patient. Not what's easiest, not what's fastest. My patients invest in their care, and I invest in the outcomes. That relationship — that mutual commitment — is what produces results that actually change lives. We accept all PPO insurance plans.
My specialty is dental implants and restorative dentistry, and I've dedicated my career to mastering it. While the minimum continuing education requirement to maintain a dental license is 25 hours every two years, I personally complete approximately 300 hours of advanced coursework per year. That's not a technicality — it's a reflection of how seriously I take my responsibility to the people who sit in my chair. When you choose me as your dentist, you're choosing someone who is relentlessly committed to being excellent at this.

His Philosophy
After treating more than 10,000 individual patients, I've learned that most people don't come to the dentist simply because they need dental work. They come because something in their life isn't working the way it should — they're in pain, they're embarrassed, they're frustrated, they've been putting something off for too long. My job isn't just to fix the clinical problem. My job is to listen to the whole story, understand what someone actually needs, and find the path forward that makes real sense for their life.
I believe that dentistry is an investment, not an expense — and I spend a lot of time helping patients understand that distinction. I also believe that the best dental outcome is one where the patient feels informed, respected, and heard throughout the entire process. Not rushed. Not judged. Not sold. Just genuinely cared for.
Smiles Change Outcomes™ isn't just our tagline. It's what I've observed in patient after patient over two decades. The way a restored smile changes how someone walks into a room. The way it changes the opportunities available to them. The way it changes their relationship with themselves. That's what we're building here.
“After treating over 10,000 patients, the one thing I know for certain is this: your smile affects everything you do. The way you introduce yourself. The way you hold yourself in a room. The opportunities you pursue”
— Dr. Michaelangelo Aust, DDS
After 10,000 Patients
5 Things I Learned
There Are Few Services as Personal as Dentistry
Think about what dentistry actually involves: a professional working inside your body as a matter of routine. Your physician checks your blood pressure, listens to your heart, places a thermometer in your ear — but a dentist has their hands in your mouth. That level of physical intimacy demands an equivalent level of personal trust and attention.
I've learned that the quality of care I can provide is directly tied to the quality of the relationship I build with each patient. When a patient trusts me — really trusts me — they're honest about their anxiety, their history, their fears. And that honesty allows me to design care that actually works for them. Personal attention isn't a soft skill in dentistry; it's a clinical necessity. If you feel comfortable enough to tell me the truth about your oral care, I can take far better care of you.
Your Oral Cavity Is a Window Into Your Overall Health
"Yes, I brush and floss every day." That's something I hear in almost every new patient consultation. And while I appreciate the sentiment, the oral cavity tells its own story — one that's often quite different.
Here's the thing I've come to understand after treating thousands of patients: the mouth is genuinely a window into your overall health. Gum disease is linked to cardiovascular disease, diabetes, and other systemic conditions. The state of someone's teeth and gums reflects not just their oral hygiene habits, but their nutrition, stress levels, medication use, and general health. I never judge what I find — I've seen every possible scenario — but I do take it seriously. More importantly, the patients who are honest with me about their habits, who follow through on recommended care, and who come in for regular check-ups consistently spend far less on dental care over their lifetime. Prevention is always less expensive than repair.
People Don't Like Paying for Dentistry — Until They Understand the Value
Many of the patients I see initially view dental care as an expense to minimize. I understand that. Quality dentistry isn't cheap, and the connection between dental care and overall quality of life isn't always obvious until you've experienced both sides of it.
Here's the equation I use to explain the value of dentistry to patients who are on the fence: take the body parts preserved (your teeth), add the daily functions restored (eating, laughing, speaking confidently), then divide by the cost of the procedure. That's your true return on investment. When a patient gets implants after years of hiding their smile — and suddenly starts going to events they were avoiding, eating foods they'd given up, engaging with people in a way they hadn't in years — that's not a small thing. That's a life rebuilt. The investment in quality dental care pays dividends that compound over a lifetime.
If You Skip the Dentist, You Cost Yourself Money
I once saw a patient who hadn't been to a dentist in years. He'd had a painful extraction done elsewhere, the fillings had fallen out, and he'd simply stopped going. By the time he came to see me, he was walking around with over $6,000 in compounding dental damage — and he'd been avoiding the dentist because he thought he couldn't afford care.
I gave him a comprehensive evaluation, built a treatment plan, and got him on a payment schedule of $90 a month. He was stunned — not just by the affordability, but by the fact that a dentist had actually sat down and explained his full situation to him instead of just patching one problem and sending him out the door. The lesson here is universal: small dental problems, left unaddressed, become expensive dental problems. A $200 filling left too long becomes a $1,500 root canal, then a $3,000 crown, then a $4,500 implant. Catching issues early — and addressing them — is almost always the less expensive path.
The More Serious Your Condition, the Less Insurance Typically Covers
This surprises almost every patient I explain it to, but it's consistently true: dental insurance is designed to cover routine, preventive care very well — and major restorative work very poorly. The more catastrophic your dental situation (full-arch reconstruction, complex implants, significant bone loss), the larger the gap between what the insurance covers and what the treatment actually costs.
This is one of the core reasons Advancements in Dental Care operates as a fee-for-service practice. I don't want insurance reimbursement rates to dictate what materials I use, what procedures I perform, or how much time I spend with a patient. My patients pay directly for the care they receive — and in return, they get decisions made entirely in their clinical interest, with out-of-network company involvement in those choices. For patients navigating significant dental needs, I believe this is the honest, better approach.
