Grandparent Consent for Dental Care in Wisconsin

Dental Offices Require Consent From Someone With Legal Authority

Dental clinics in Wisconsin — like any healthcare provider — need signed consent from a person with legal authority over the child before they will examine, clean or treat a minor's teeth. Being a grandparent is not enough on its own. Wisconsin does not recognize a self-executing caregiver affidavit for healthcare, so a grandparent needs either a Power of Attorney (Form GF-223) or a court-ordered guardianship.

This becomes an urgent problem when a child arrives in a grandparent's home with untreated cavities, a toothache that will not wait, or overdue routine cleanings.

Getting Dental Consent Through GF-223

Form GF-223 — the Power of Attorney Delegating Parental Power under Wis. Stat. § 48.979 — explicitly covers dental treatment. When a parent signs this form and names a grandparent as agent, the grandparent can:

• Schedule and attend dental appointments
• Sign intake forms and treatment consent
• Authorize routine cleanings, X-rays and fluoride treatments
• Consent to fillings, extractions and restorative work
• Present dental insurance cards and discuss coverage

The parent who holds legal custody must sign the form. If both parents share joint legal custody, both must sign. The form lasts up to one year and can be renewed.

What About Orthodontics and Oral Surgery?

The standard GF-223 covers routine dental care. For anything beyond routine treatment — orthodontic braces, wisdom tooth extraction under general anesthesia, jaw surgery — the line between routine and extraordinary care gets blurry.

The safest approach is to have the parent attach a written addendum to GF-223 specifying that the agent may consent to orthodontic treatment, oral surgery under sedation, or whatever procedures the child is likely to need. Without an express addendum, a dentist or oral surgeon may refuse to proceed on the standard form alone.

Getting the Paperwork to the Dental Office

Bring a copy of the signed GF-223 to the dental office at the first appointment and ask that it be scanned into the child's file. This prevents the front desk from asking for parental consent at every subsequent visit.

If the form is notarized, lead with the notarized copy. Notarization is optional under Wisconsin law, but dental office staff are more comfortable with a notarized document.

Also bring:

• The child's dental insurance card (if coverage exists through a parent's plan or BadgerCare Plus)
• A list of the child's current medications and allergies
• Any recent dental records from the child's previous dentist, if available

Dental Insurance Through BadgerCare Plus

If the child does not have dental coverage through a parent's insurance plan, apply for BadgerCare Plus through ACCESS.wi.gov. BadgerCare Plus covers children's dental care — cleanings, fillings, extractions and emergency dental services. Eligibility is based on the child's financial circumstances, not the grandparent's income.

Children enrolled in BadgerCare Plus can see any participating dentist in the Medicaid dental network. If the child's current dentist does not accept BadgerCare, the ForwardHealth provider directory lists participating providers by county.

If the Dentist Refuses

If a dental office refuses to see the child despite a valid GF-223:

1. Ask the front-desk staff to explain the specific policy basis for the refusal.
2. Point to Wis. Stat. § 48.979, which authorizes delegation of healthcare consent including dental care.
3. Ask to speak with the practice owner or office manager.
4. If the refusal continues, find another dentist and file the interaction in your records — the Wisconsin School and Medical Consent Guide includes a refusal and escalation log for tracking these situations.

Most refusals happen because the front desk has never seen a GF-223 before. A calm explanation of the statute and a notarized copy usually resolve the issue.

Emergency Dental Care

In a genuine medical emergency, a provider may render immediate life-saving care or emergency diagnostic treatment without prior consent when obtaining consent would dangerously delay treatment of an acute threat to the child's life or health. This does not extend to scheduled follow-up or non-urgent care once the emergency resolves.
