Before you book

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.

  1. 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 Montana Medicaid 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?
  2. Verify the dentist & availability

    • Is Charles Douglas Vandyck III 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?
  3. Verify the license yourself

    Search the Montana Board of Dentistry license-lookup to confirm the license is active and in good standing — federal records do not show state-level discipline. Open the Montana Board of Dentistry site →

  4. 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?

About periodontists

What is a periodontist?

A periodontist specializes in the structures around the teeth: gums, bone, and the periodontal ligament. They treat gum disease (gingivitis and periodontitis), perform gum and bone grafts, place dental implants, and handle aesthetic gum procedures like crown lengthening.

Training. After dental school, a periodontist completes a 3-year accredited residency in periodontics and implant dentistry. Board certification is through the American Board of Periodontology.
