What Makes Us Different

The best smiles come from
Good Company Dental ( Cottleville Smiles)

Great dentistry doesn’t come from the fanciest equipment or the biggest office. It comes down to three things
— and we’ve built everything around them.

Good Doctors

Every provider we bring on is hand-picked — not just for clinical skill, but for how they treat people. Doctors who live in this community, invest in it, and genuinely care about the person sitting across from them.

Good Teams

From the first phone call to the final follow-up, every person on our team is here because they love taking care of people. The warmth you feel walking in isn't an accident — it's who we hire.

Good Patients

You're not a chart number. You're the reason we built this. We take on patients who are ready for a real relationship with their dental home — and we hold up our end every single visit.

The way dental care should feel.

We don’t just treat teeth. We take care of the person attached to them.

We listen first.

Before we look at a single X-ray, we want to hear from you. What's been bothering you. What you've been putting off. What you're hoping for. You'll never feel rushed, judged, or talked over here.

01

We educate, not pressure.

We'll show you exactly what we see and explain every option clearly. Then the decision is yours — always. No upselling, no pressure, no recommendations we wouldn't make for our own families.

02

We see the full picture.

From what needs attention today to where your smile could be in five years, we think long-term. Because the best care is proactive, not reactive — and we plan to be your dentist for life.

03

We build real relationships.

Your doctor remembers you. Your hygienist knows your history. The front desk knows your name when you walk in. That's not a small thing — that's the whole difference between a dental office and a dental home.

04

How We Can Help

Care that meets you where you are.

Whether something hurts right now, you want to stay on top of things, or you’re finally ready to do something about that smile — we’re here for all of it. No judgment on where you’re starting.

Relief

Something needs attention now
Pain, a broken tooth, something you've been putting off — we move fast when it matters. Same-day appointments available, clear answers, and a team that takes your discomfort seriously from the moment you call.

01

Maintenance

Keeping what you have
Consistent care, honest checkups, and a long-term relationship with a doctor who knows your history. The goal is a healthy smile for life — and a team who helps you actually get there.

02

Transformation

Life-changing dentistry
Veneers, implants, whitening, full smile design — for people who are ready to finally love what they see. Dr. Tanner personally handles every case and treats each transformation like it's his own. Because in a way, it is.

03

Our Specialties

The Experience

Every visit
should feel like this.

We obsess over every interaction — because the experience is the care. How you feel from the first phone call to the final follow-up matters just as much as anything that happens in the chair.

That’s how families started driving past other dentists to get here. And it’s how they keep finding their way back.

The First Call

"A real person picked up. They actually had time for me."

Walking In

"They knew my name. The doctor sat down before anyone touched anything."

The Conversation

"He showed me what he saw, explained my options, and let me decide. No pressure."

After the Visit

"They checked in on me the next day. I didn't expect that."

Real Words From Real Patients

My 3 year old daughter and I had our first visit today at Cottleville Smiles and could not be happier. Easy to schedule, front desk staff was super friendly. Laura, the hygienist, and Dr. Brown were extremely gentle and thorough. There was another hygienist that played with my daughter while I had my x-rays done and they gave us a branded tumbler and toys from the treasure chest. You will not be disappointed!

Maura S.

When we first arrived, one of the receptionists saw that my husband was pushing my wheelchair to the door. She quickly got to the door and held it open for us. Great! Lindsey, who cleaned my teeth was very gentle and she is such a friendly lady! She put me at ease and explained everything she was doing. She is very knowledgeable and professional. Dr. Tanner has a great team!

Betty C.

As always, I was greeted when I walked in to the office. It was a short wait and I was taken back to get my cleaning. The hygienist was very professional and easy to work with. A very good experience. Dr. Brown was also very professional and was very good at explaining what he was doing and what I needed to watch for. All in all, very enjoyable visit.

Timothy W.

Fantastic experience. Beautiful and clean office with warm, welcoming staff. Visit was timely and everyone was so helpful and kind. Laura did a great job and was wonderful with explanations. Dr. Beau was very kind and professional. I had new baby with me and everyone was very accommodating and understanding. Would highly recommend!

Lindsay T.

This is the best dentist office I have ever been to! The staff was so friendly and gentle with me as I had a bad experience at another place. I highly recommend anyone who has a fear of the dentist to come here, they will take great care of you! The environment is so warm and comforting it almost feels like you are at home instead of the traditional dentist office. They truly go above and beyond.

    A New Name. The Same People. An Even Bigger Vision.

    Cottleville Smiles is now Good Company Dental.

     

    As our practice has grown, we wanted a name that better reflects what has always mattered most to us: building meaningful relationships, caring for our community, and creating an exceptional experience for every patient who walks through our doors.

    You may still see our previous name throughout portions of this website as we complete updates, but you’re in the right place.
