Five-minute checklist before you call
Federal data tells you a dentist exists and is enumerated. It does not confirm insurance acceptance, current availability, or office fit. Use this list when you call so the visit isn’t a surprise.
Confirm insurance & out-of-pocket cost
- “Do you accept my exact insurance plan? (give the carrier, plan name, and member ID)”
- “Are you accepting new AHCCCS patients right now?”
- “What is the out-of-pocket cost I should expect for the type of visit I need?”
- “If you are out of network for me, can you bill my insurer or only me?”
Verify the dentist & availability
- “Is John Malcolm Gillis the dentist who will see me, or another provider in the practice?”
- “Are you accepting new patients? When is the next available appointment?”
- “Will the same dentist handle follow-up visits, or rotate?”
Verify the license yourself

Match office services to your needs
- “Do you offer emergency or same-day appointments? After-hours number?”
- “What languages do your front desk and clinical staff speak?”
- “Is the office wheelchair-accessible? Any accommodations available on request?”
- “Do you offer sedation options for anxious patients (nitrous, oral, IV)?”
- “Do you treat pediatric patients in this practice, or refer them to a pediatric dentist?”
- “For surgical procedures, what post-op support is available the same day and overnight?”

What is an oral and maxillofacial surgeon?
An oral and maxillofacial surgeon (OMFS) handles the surgical end of dentistry: complex extractions including impacted wisdom teeth, dental implants, bone grafting, jaw reconstruction, treatment of facial trauma, and orthognathic (corrective jaw) surgery. They're also licensed to administer general anesthesia in-office.
Training. After dental school, an oral surgeon completes a 4- to 6-year hospital-based residency. Some programs include a medical degree (MD) integrated into the residency. Board certification is through the American Board of Oral and Maxillofacial Surgery.
