Before you come to the dentist near Gillette

We understand coming to a dentist near Sturigis can be a challenge, so here is some help:

  • Think positive. Try to be open minded about what the experience will be like. Less stress+relaxed=better experience.

  • Give yourself kudos for taking a step to care for your teeth.

  • If you’ve had a bad experience in the past, let us know so we can avoid repeating it.

  • Bringing in kiddos? Keep it light. Keep it positive. You are their role model.

  • Children do best without a parent in the room. They can then develop a good relationship with the doctor and staff.

Ideally we like to start with a new patient exam, but we understand emergencies do come up. We will recommend a full exam once the emergency has been dealt with.

Recare and restorative visits with a dentist near Gillette

Our philosophy is to keep your natural teeth for a lifetime with the least intervention by us. We do this by having regular check-up visits and teaching preventive measures. This allows us to monitor any changes you may have such as cavities, hygiene care, and diet. Also, it gives you the opportunity to ask questions and talk about any alternatives you may desire for your teeth. While the responsibility for returning for treatments rests with you, we try our best to schedule you in advance to reserve the time for your next visit. At the time of your visit please advise the office of any changes of contact info, dental insurance, and health/medication changes.

Gillette Dentist Scheduling Guidelines

  • Consider that restorative appointments are scheduled by treatment time needed. We have to allow time for items such as anesthetic to work or materials to set.

  • Consider other patients when running late as it could conflict with their care. Be aware of travel time to appointment.

  • Understand that we may have to reschedule you if you are running late to be able to assist others/emergencies.

  • Let us know if you cannot keep your appointment. The further the advance notice the better. (Preferably 24 hours)
