Why a Pediatric Dentist?

Just as a pediatrician specializes in children's health, pediatric dentists are experts in the growth and development of children's mouths.  They can spot problems such as early decay or crowded teeth - and correct them - before they do major damage.

Pediatric dentists know as much about kids as they do about children's dentistry.  They undergo extensive training in child development and child psychology, which means they can calm kids fears about dentists and make visiting the dentist a fun, positive experience.

The specialized care doctors at Post Oak Pediatric Dentistry provides can make a big difference in the way your child feels about going to the dentist.  That can have a major impact on the way they care for their teeth!  They are committed to helping kids learn how to properly care for their teeth and develop the good brushing habits that get their smiles started out right.

An Expert in the Special Dental needs of Children and Teens

"I love to see kids smile and I'm committed to giving them the best dental care available to make their smiles healthy and beautiful.  That is why I stay so active in professional associations and continuing education.  It takes a lot of work to keep up with the latest techniques but it's worth it when I see bright, healthy teeth smiling back at me after an exam."

"It's important that kids feel relaxed and comfortable with their dentist. That's why our office is filled with toys and activities."  We have a tooth-brushing center, where kids can see their teeth while we show them how to brush, and we send a pink-costumed bear, Molly the Molar Bear, and smiling Lion to local schools and day-care centers to teach kids about caring for their teeth. "I believe the positive experiences the children enjoy in our office encourage them to take an active role in taking good care of their smiles for the rest of their lives."

"Kids need a dentist who understands how to care for their teeth as they develop. I spent years learning what those needs are, and I'm committed to continuing my education so that I can provide the latest, best treatments available to help kids build strong, healthy smiles."

On the Forefront of Dental Technology and Interventive Orthodontics

"Offering quality care means keeping up with the latest equipment and techniques, such as digital x-rays and air-abrasion, no-drill dentistry for pain-free fillings."

"Wearing braces isn't the traumatic experience it used to be. With early intervention, kids can wear their braces for much shorter periods of time - and with the latest equipment, they choose from nearly invisible tooth-colored braces or bright, fun colors, like glow- dark or their favorite team colors."
