To our family of patients,

We have made the very difficult decision to close our office to all elective dental procedures effective March 26, 2020. This closure is at the recommendation of the Missouri Dental Association, CDC and the American Dental Association. The safety of our patients, staff, and families is our primary concern during this ever-changing health crisis and we need to do our part to help “flatten the curve”.

Our office will plan to tentatively reopen April 30, 2020, but of course this is subject to change with the uncertainty surrounding the Covid-19 pandemic. We will be available to treat any true dental emergencies (i.e. pain, swelling, and trauma) throughout this time of closure.

My amazing dental team and I want to THANK YOU for entrusting us with caring for your oral health!  We value our relationships with you, and we assure you that we are doing everything we can to continue to provide you with excellent experiences in our office.  We are also dedicated to protecting your health, and the health of all those in our communities and beyond.

Thank you for your patience and understanding during this difficult time. We will be back to our normal schedule as soon as we possibly can. Take care, wash your hands, and be safe!

Dr. John G’Sell D.D.S., M.A.G.D.  and Staff

Making Your Dental Care Comfortable

We know that dental visits can be stressful for some patients, especially when you’ve had negative experiences in the past.

For patients who feel anxiety during dental visits, we offer nitrous oxide sedation to help make your visits a more positive and relaxing experience.
