Dr. Cynthia Blalock, DDS Dentist

“I HATE GOING TO THE DENTIST” – said almost every person, ever.

I get it. I really do. Going to the dentist can be an unpleasant experience. Believe me. If you had to take blood from my arm you had better treat me like a 4 year old and there had better be a lollipop with my name on it when we’re done! That’s why I’ve made it my mission to bring comfort to every person that comes into Cardinal Dental.

Allow me to introduce myself. I’m Cyndi Blalock, DDS and I am the founder of Cardinal Dental in St. Peters, MO. I became a dentist so I could help give people a reason to smile and beautiful teeth to do it with. 

No matter what your age, my team and I will do everything in our power to make the time you spend with us as enjoyable as possible.

At our office, we take extra steps to give you a more comfortable experience. Things like a warm cozy blanket, memory foam dental chairs, and coffee bar.

But that’s not all.

We become part of your family and really get to know your likes and preferences. Looking for fluoride-free products? We got you. Need a comfortable place to nurse your baby? We got you. Can’t get out of work during the day and need an evening appointment? We got you. Don’t have dental insurance and want to have a healthy, affordable smile? We got you. 

It is our mission to provide state-of-the-art, gentle dental care to every member of your family.


“I had a wonderful experience at Cardinal Dental. The office is very nice and the people are even more so. Fast and friendly, I was well taken care of. My hygienist was very delicate, no pain at all and a wonderful cleaning.”
