Comprehensive Dental Care — From Preventive Exams to Complete Smile Restorations

Dental Services We Offer

We provide comprehensive dental care in Fenton, MO — where you'll see the same doctors every visit and never feel like you're just moving through a system. Our care spans preventive dentistry, restorative treatments, cosmetic services, periodontal therapy, dental implants, root canals, and emergency care — all in one place, without the runaround of outside referrals. With over 20 years of experience, advanced training through the Kois Center, and a diagnostic approach that goes beyond surface-level fixes, we focus on understanding why problems happen so they don't keep coming back. Every appointment is unhurried, judgment-free, and built around one simple question: what would we want if this were someone we care about?

Cosmetic Dentistry

Your smile affects how you feel in every conversation, every photo, and every room you walk into. Whether you're looking for a brighter smile, straighter teeth, or a complete transformation, we take the time to understand what you want and craft results that look natural and last. No cookie-cutter plans — just care designed around you.

  • Teeth Whitening

  • Porcelain Veneers

  • Invisalign®

  • Bonding

Restorative Dentistry

Missing, damaged, or failing teeth don't just affect your smile — they affect how you eat, speak, and feel every day. We handle everything from single-tooth replacements to full-mouth rebuilds right here in our office, with the same doctors who already know your history. One team, one plan, no runaround.

  • Dental Implants

  • Dental Crowns

General Dentistry

This is the foundation of everything we do — and the reason most problems never become emergencies. Regular visits give us the chance to catch small issues early, keep your gums healthy, and make sure your mouth stays in great shape for years to come. When something does need attention, we handle it here without referring you somewhere else.

  • Dental Cleanings & Checkups

  • Fillings

  • Tooth Extraction

  • Wisdom Teeth Removal

  • Root Canal Treatment

Emergency Dental Care

Dental pain doesn't wait for business hours — and neither do we. If something breaks, swells, or hurts, call us. We'll get you in, get you out of pain, and figure out what's next. And if you're already a patient here, we know your history, which means faster, safer care when it matters most.

  • Toothaches

  • Knocked-Out Teeth

  • Loss of Filling or Crown

  • Objects Stuck in Teeth

  • Chipped or Cracked Teeth

What OUR PaTIENTS are saying

MEET OUR DOCTOR

Dr. Mark Garner

Dr. Adam DeCota has spent more than a decade building a practice centered on one belief: that great dentistry solves problems at their source. Specializing in adult cosmetic and rehabilitative dentistry, Dr. Adam has invested hundreds of hours in continuing education through programs like the Seattle Study Club, the Dawson Center, and the Scottsdale Center — developing the clinical depth needed to handle complex, full-mouth cases with both precision and care. He has also completed a mini-residency in implant placement through the McGarry Implant Institute and earned recognition as one of the top 40 dentists under 40 by Incisal Edge magazine.

The cornerstone of Dr. Adam's clinical growth is his long-standing relationship with the Kois Center in Seattle — one of the most rigorous post-graduate dental programs in the country. After completing the nine-course curriculum, written examination, and clinical skills assessment required to earn his certificate, Dr. Adam went on to achieve the distinguished designation of Mentor — a role that means he now returns to teach and guide other dentists through the same advanced concepts in aesthetics, implant, and restorative dentistry. It's a responsibility he takes personally. "Becoming a Mentor has been a huge growth experience for me both personally and professionally," he shares. "As I go back and teach, I come away with even more knowledge. I truly consider this award a reward."

Beyond his clinical credentials, Dr. Adam is an active member of the St. Louis Dental Society, the Missouri Dental Association, the American Dental Association, and the Fenton Chamber of Commerce — reflecting a genuine commitment to both his profession and the community he serves. At DeCo Dental, that commitment shows up in how he approaches every patient: not as a case to fix, but as a person deserving of honest answers, thoughtful planning, and care that holds up for years to come.

FREQUENTLY ASKED QUESTIONS

Do you accept dental insurance?

Yes, we accept most major PPO dental insurance plans. Our team verifies your benefits and handles the paperwork so you don't have to worry about it. We'll always let you know what's covered before any treatment begins, and we offer flexible financing options if your care goes beyond what insurance covers. Give us a call at 636-251-4987 and we'll check your plan before your first visit.

What should I expect at my first visit?

Your first visit is a comprehensive exam, not a rushed cleaning. We take the time to look at everything — your teeth, your gums, your bite, and your overall oral health. We use digital X-rays and advanced imaging when needed, and we sit down with you to explain what we're seeing in plain language. There's no pressure to commit to a treatment plan on the spot. We believe the best decisions happen when you feel informed and comfortable.

Do you handle dental emergencies?

Absolutely. Dental pain doesn't follow a schedule, and neither do we. If you have a cracked tooth, a severe toothache, swelling, or any urgent dental issue, call us at 636-251-4987. Our phone rings directly to the doctors, even after hours. If you're already a patient, we know your history, which means we can treat you faster and more safely when it matters most.

Do I really need to come in twice a year if nothing hurts?

Yes, and here's why — most dental problems don't hurt until they've already progressed. A small cavity that's painless today can turn into a root canal six months from now. Early gum disease has no symptoms at all until bone loss begins. When you come in twice a year, we catch those small issues early while they're still simple and affordable to fix. Think of it less as "just a cleaning" and more as protecting your future health, your comfort, and your wallet.
