I’ve been going to Dr. Gary Riddle D.D.S. for a little over 30 years now.  I was one of his first patients when he purchased his office building in Scott City, MO.  and have only gone to one other dentist during that time.  I moved and hour and a half away so I went to a dentist that was closer to me.  That was the last time that happened.  I quickly decided that it was in my best interest to drive the hour and a half twice a year to see Dr. Riddle.

During those 30 years, I had 2 beautiful daughters that I brought to Dr. Riddle as soon as they were old enough to sit in the exam chair.  It’s very important to get a sealant put on their little teeth to prevent cavities.  Now, they bring their babies to him.  They each have at least a 2 hour drive to get to him but they don’t mind at all.

Dr. Riddle gave me a beautiful bright smile with Veneers and Zoom Whitening.  I couldn’t be happier!

pediatric dentistry

Parents often ask at what age they should bring their child in for a dental check up. We like to see the kids when they are about 2 1/2 to 3 years old, unless you see a problem before that, such as black or brown spots on the teeth, or no teeth or gum sores.
