NOTICE: Temporary closure for non-emergency patients

Based on recommendations from the CDC, Missouri Dental Board, and St Charles County Health Department, we will be closing our office to non-emergency patients on 3/18/2020 until 4/1/2020. Dr. Blalock will be available for emergencies during that time. Please call the office at 636-441-7440 to leave an emergency voice message.

It has been recommended that people who are experiencing dental pain avoid crowding the hospital emergency rooms and urgent cares to make room for caring for patients experiencing coronavirus symptoms. Dr. Blalock will be available to the community for virtual visits for patients experiencing dental pain.

Emergency Virtual Visits can be made online and can be made 7 days a week.

The cost for a virtual visit is $29.

Every child is special and unique

children st peters mo at cardinal dental

Every child is special and unique, and their dental needs should be tailored to be as exquisite as they are. At Cardinal Dental, we provide tailored care for your child by focusing on prevention and education. Our goal is that your child grows up to be a good dental patient free of fear and anxiety. We faithfully provide compassionate and comfortable dental care services, and we treat your child as if they are a member of our own family.

A trip to the dentist doesn’t have to be scary.

That’s why at Cardinal Dental we have developed a program that eliminates the fear of going to the dentist and makes it a fun experience. Our popular Tooth Fairy and Friends event incorporates magic and compassionate care into making your child’s first trip to the dentist exciting and anxiety free.

Does your child have difficulty breathing while sleeping?

Does your child snore or suffer from ADD/ADHD, bed wetting, difficulty in school, or daytime drowsiness? Then he or she may have Pediatric Sleep-Disordered Breathing (SDB), and might benefit from the Healthy Start program. Dr. Blalock is one of only a handful of providers in the St. Louis area to offer this life changing treatment.

“Dr. Cynthia has been the sweetest and most patient dentist with my son. While doing dental work, she went above and beyond to comfort my son who was anxious. She has a very fun and gentle demeanor that put my son at ease. “

Brush their teeth 2 times a day

Children are encouraged to brush their teeth 2 times a day for two minutes. Parents should help their children brush their teeth until the age of 10 to prevent cavities. A soft bristled toothbrush and fluoride toothpaste are recommended for children over the age of 3. Children under the age of 5 should not brush their teeth unsupervised. The more parents can help their children with their oral hygiene, the less likely their chances of getting cavities.
