How Sliding-Scale Fees Work
Sliding-scale dental clinics are federally funded health centers that adjust what you pay based on your household income. The goal is to make dental care affordable for uninsured and underinsured people.
Instead of a flat fee, your payment is tied to the Federal Poverty Guidelines—a measure the U.S. government uses to define poverty levels by household size. The clinic’s sliding scale typically has several tiers:
- At or below 100% of the Federal Poverty Guideline: You may qualify for the full discount, paying little to nothing.
- 100–200% of the guideline: You enter a middle tier, paying a reduced fee scaled to your income.
- Above 200% of the guideline: You may pay standard fees or a smaller discount, depending on the clinic’s policy.
Your income—not your ability to pay in full—determines your tier. The clinic calculates this at intake using documents you bring.
What to Bring to Your First Appointment
Bring:
- Photo ID (driver’s license, state ID, or passport)
- Proof of income (recent pay stubs, tax return from last year, Social Security statement, unemployment or benefit paperwork)
- Proof of residency (utility bill, lease, or mortgage statement—some clinics ask for this; call first to confirm)
- List of any current medications (write them down; don’t assume the clinic has your records)
- Your insurance card, if you have any coverage (Medicaid, AHCCCS in Arizona, private, etc.)
The clinic will review these documents during intake and calculate which tier you fall into. Be honest about your household income and size; the clinic uses this to set your fee, not to judge you.
Confirming Coverage and Services
Not every dental clinic offers every service. Before you schedule or show up, call and ask:
- “What dental services do you provide?” (Some clinics do cleanings and exams only; others include fillings, extractions, or emergency care.)
- “Do you accept patients with my income level?” (Rare, but some clinics may have wait lists or specific eligibility windows.)
- “Can you treat my specific tooth problem?” (Don’t assume; describe what you need.)
- “What if I can’t afford the sliding-scale fee?” (Some clinics have emergency funds or can negotiate further.)
If the clinic can’t help you, ask for a referral to another provider nearby.
The Connection to Arizona Medicaid (AHCCCS)
If you live in Arizona, check your eligibility for AHCCCS (Arizona’s Medicaid program) first. AHCCCS covers dental care for eligible members, and coverage may be broader or simpler than a sliding-scale clinic’s offerings. See our guide on AHCCCS dental coverage to learn more. If you’re not eligible for AHCCCS or it doesn’t cover your specific need, a sliding-scale clinic is a strong option.

Frequently asked questions
What income proof do I need to bring to a sliding-scale clinic?
Most clinics ask for recent pay stubs, tax returns, Social Security statements, or proof of benefits. Bring a photo ID and sometimes proof of residency (like a utility bill). Call ahead to ask exactly what documents your local clinic needs.
Does every sliding-scale clinic cover the dental service I need?
No. Some clinics focus on preventive care (cleanings, exams, X‑rays); others offer restorative work or extractions. Before your first visit, call and describe what you need—don't assume it's available.
If I'm on Arizona Medicaid (AHCCCS), should I go to a sliding-scale clinic instead?
Not necessarily. AHCCCS may cover your dental care at participating providers. Check your coverage first. If you're not eligible for AHCCCS or need services it doesn't cover, a sliding-scale clinic is a good backup option. See our guide on AHCCCS dental coverage for more details.
