Dr. Corey Hastings

I am passionate about dentistry for children and helping them reap the benefits of healthy teeth and a great-looking smile for life! If there’s one thing I hope to accomplish in my career, it’s helping all of my young patients learn to love visiting the dentist. There’s absolutely no reason a dental appointment should be intimidating. When children realize that seeing the dentist can be relaxing and enjoyable, they pay closer attention to their teeth and gums between visits. It’s my job to help children learn and understand the real benefits of excellent oral health.

When I’m not in the office, I enjoy staying active with my wife and son. We appreciate living so close to St. Louis and exploring all the city has to offer. We are avid Cardinals fans and cheer on the team at every possible chance! The top of my list of favorite things includes: everything having to do with Marvel Universe, traveling, spending time with friends and family, and seeing my patients and their families around town.

I absolutely love Gateway Little Smiles and the care they provide for my boys! Mo took great care of them and made sure they felt comfortable throughout their visits. He was patient, kind, and professional, and I truly appreciate the care and attention he gave my boys. The entire staff was friendly and welcoming, making the experience a positive one. As a mom, it means so much to know my children are in good hands and receiving excellent care. Thank you, Mo, and Gateway Little Smiles for taking such great care of my boys! I highly recommend Gateway Little Smiles to any parent looking for a wonderful dental office for their children! 🦷❤️

 Trustindex verifies that the original source of the review is Google. Our shy toddler was treated with warmth and patience as soon as we walked in the door! Her first appointment was very quick to help get used to visits, but everyone was still thorough and took time with our questions and concerns. The office is spacious and welcoming, with plenty to keep a little one distracted. Very happy that we chose a bit of a drive to Gateway Little Smiles!

 Trustindex verifies that the original source of the review is Google. Both of our toddler boys go here. They’re so patient and good with the littles. Our oldest is a social butterfly and doesn’t know a stranger, but our youngest is shy and very reserved until he warms up. They handle both of them so well. Explain things thoroughly. And we are so happy to start a healthy relationship with dental hygiene for both of our kids. We’re so glad we found little smiles. Oh and the welcome packet they send in the beginning is ADORABLE!
