At our Columbia office, we have plenty of parking right out front, and around the entirety of our building.

How Long Will My Dentist Appointment Take?

Everyone has different dental needs, and is in our office for a unique reason, so the length of your visit will vary depending on what you’re visiting for. If you’re just in for a routine cleaning, exam, or consultation your appointment will most likely take somewhere around an hour. Periodontal cleanings and other more complex services will last longer, although the length still varies, treatment to treatment, patient to patient.

With that said, however, we do understand that life can be busy, and that having at least a decent idea of how long your visit will be can be incredibly helpful. With that in mind, if you are curious about how long your appointment will be, give us a call at (618) 400-0550 and one of our friendly team members will be able to provide you with the answers you’re looking for, so you can plan accordingly.
