Who Signs the Consent Form? Guardianship, Supported Decision-Making, and Dental Treatment

Key Takeaways

• The person who accompanies a patient to a dental appointment is not necessarily the person who has legal authority to consent to treatment.
• Guardians, healthcare agents, or others with appropriate legal authority may make healthcare decisions in certain circumstances, but their authority depends on the applicable documents and state law.
• Supported decision-making helps patients participate in choices to the greatest extent possible, rather than automatically transferring every decision to someone else.
• Even when another person must provide legal consent, the dental team can still seek the patient’s understanding, preferences, cooperation, and assent.
• Families and caregivers should clarify decision-making authority and gather relevant documentation before treatment, particularly when complex treatment, sedation, or hospital dentistry may be necessary.

For many adults, agreeing to dental treatment is relatively straightforward: the dentist explains what is recommended, the patient asks questions, and the patient decides whether to proceed.

For patients who need additional assistance, however, the process can be more complicated.

An adult with a cognitive or developmental disability, dementia, a neurological condition, or another circumstance that affects decision-making may have family members, professional caregivers, care managers, guardians, or other representatives involved in their care. One person may manage finances, another may provide day-to-day support, and someone else may have legal authority to make healthcare decisions.

Understanding those roles before dental treatment begins can make the process easier for everyone. Just as importantly, having another person involved in legal decision-making does not mean the patient should be left out of decisions about their own care.

Who Can Consent to Dental Treatment?

Informed consent is more than a signature. It is a process in which the dentist explains the proposed treatment, its risks and benefits, reasonable alternatives, and the consequences of declining treatment, while giving the patient or authorized decision-maker an opportunity to ask questions.[1]

When an adult is able to make their own healthcare decisions, the patient generally provides their own consent.

When another individual has legal authority to make healthcare decisions, the situation may be different. Depending on the circumstances and applicable state law, that individual could be a court-appointed guardian or conservator, an agent named in an advance healthcare directive, or someone who has been granted healthcare decision-making authority through an appropriate power of attorney.[2]

Importantly, being a patient’s parent, sibling, adult child, caregiver, or emergency contact does not by itself establish authority to make every healthcare decision for that adult.

That distinction can surprise families, especially when a relative has been making appointments, paying bills, helping with daily activities, or coordinating medical care for years.

One Family, Several Different Roles

Consider an adult who lives in a supported residential setting.

A sibling may oversee the patient’s finances. A parent may remain closely involved in care. Residential staff may bring the patient to appointments. A professional care manager may coordinate with physicians. Meanwhile, a different individual may hold the legal authority to make healthcare decisions.

These responsibilities can overlap, but they are not necessarily interchangeable.

That is why a dental office may need to determine who has authority specifically for healthcare decisions and review the documentation establishing that authority. The scope matters too. Federal healthcare privacy guidance notes that someone’s authority may be broad or limited to particular healthcare decisions.[2]

Resolving these questions before treatment day is especially helpful when a patient may need extensive dentistry, sedation, anesthesia, or treatment in a hospital.

Supported Decision-Making: Helping Without Taking Over

Needing help making a decision is not necessarily the same as being unable to participate in that decision.

Supported decision-making is an approach in which a person receives help from trusted individuals to understand, consider, communicate, and make choices while retaining as much decision-making authority as possible.[3]

Support can take many forms.

A caregiver might explain information using familiar words. A family member might help the patient compare two options. The dental team might use pictures, demonstrate what will happen, break information into smaller steps, or give the patient additional time to respond.

The goal is not simply to obtain a signature. It is to make the decision-making process as accessible as possible.

Research examining healthcare consent for adults with intellectual disabilities has found that communication, accessible information, relationships with healthcare professionals, and appropriate support can all influence a person’s ability to participate meaningfully in consent decisions.[4]

This concept also reflects the dental profession’s emphasis on patient autonomy. The American Dental Association states that dentists should involve patients meaningfully in treatment decisions, taking their individual needs, desires, and abilities into consideration.[5]

Consent and Assent Are Not the Same Thing

There may be circumstances in which a patient cannot provide full legal informed consent and an authorized representative must consent on their behalf.

But that does not mean the patient’s response becomes irrelevant.

This is where the concept of assent can be useful.

In this context, assent means involving the patient in a way they can understand and looking for their willingness to participate, even when they are not the person providing formal legal consent. Clinical guidance for adults with developmental disabilities recommends adapting communication to the individual and recognizing that people who cannot independently provide informed consent may still be able to understand information, express preferences, and provide assent with appropriate support.[6]

For example, a patient may not be able to understand every clinical detail of a proposed restoration, but they may understand:

“We are going to help your tooth feel better.”

They may be able to indicate whether they are comfortable sitting in a particular chair, whether they want a caregiver nearby, or whether they would like a short break.

Those choices matter.

Small Choices Can Make Dental Care Feel More Manageable

Supported decision-making does not have to involve complicated decisions.

Sometimes meaningful participation starts with very small choices:

• “Would you like the blue toothbrush or the green one?”
• “Would you like your caregiver to stay next to you?”
• “Should we look at your teeth first or take the picture first?”
• “Would you like to sit up for a minute before we continue?”

Offering two manageable choices can be more effective than asking an open-ended question that may feel overwhelming.

These choices do not replace informed consent for treatment. Instead, they help preserve the patient’s sense of control within the treatment process.

For patients who have difficulty tolerating dental care, that sense of control may also help reduce resistance and make cooperation easier.

What Are Families Actually Signing?

Dental consent forms can appear intimidating, particularly when treatment involves multiple procedures or sedation.

Typically, informed-consent discussions address matters such as the condition being treated, the recommended procedure, expected benefits, material risks, alternatives, and what could happen if treatment is postponed or declined.[1]

The signed form documents part of that process. It does not replace the conversation between the dentist and the patient or authorized decision-maker.

For complex treatment, the ADA recommends obtaining informed consent in advance so that the patient has adequate time to consider the risks, benefits, and alternatives.[1] Consent should also be obtained before medications or sedation that could impair the patient’s ability to reason or make decisions are administered.[1]

That makes preparation particularly important for patients receiving sedation or hospital-based dental care.

What Families and Caregivers Can Do Before the Appointment

Before a first appointment or planned procedure, families can help by determining who has legal authority to make healthcare decisions and gathering the documents that establish that authority.

It can also be helpful to tell the dental team:

• how the patient best understands information
• how the patient communicates yes, no, discomfort, or anxiety
• which family members or caregivers should participate in discussions
• what tends to calm or overwhelm the patient
• how much assistance the patient typically needs when making decisions
• whether there are existing guardianship, conservatorship, advance-directive, or healthcare power-of-attorney documents

Providing this information ahead of time gives the dental team an opportunity to plan for the individual rather than trying to sort everything out immediately before treatment.

The Goal Is More Than a Signature

For patients who need additional support, the best consent process is not simply about identifying the person authorized to sign a form.

It is about balancing legal responsibility with respect for the person receiving care.

Sometimes a patient will make the decision independently. Sometimes they will make the decision with support. In other circumstances, an authorized representative will make the final legal decision.

Across all of those situations, the patient can still remain at the center of the process.

Whenever possible, explaining what is happening, adapting communication, offering meaningful choices, listening to preferences, and seeking cooperation can preserve something that matters just as much inside the dental office as it does everywhere else: the patient’s agency and dignity.

How Blende Dental Group Supports Patients and Decision-Makers

At Blende Dental Group, many of the patients we care for need more than a standard dental appointment. Some rely on family members, guardians, care managers, residential staff, or other healthcare professionals to help coordinate treatment. Others may need house-call dentistry, sedation, or hospital-based care because of medical, cognitive, physical, or behavioral needs.

Our approach is centered on coordination and individualized care. We work with the patient, the person authorized to make healthcare decisions when applicable, and the broader care team to understand the patient’s needs before treatment begins.

Whenever possible, we also involve the patient directly in the process. That may mean adapting how information is explained, allowing additional time, involving a familiar caregiver, or offering simple choices that help the patient maintain a sense of control and participation.

For more complex cases, including treatment involving sedation or a hospital setting, clarifying decision-making authority and gathering the appropriate documentation in advance can help make the experience smoother for the patient, family, caregivers, and clinical team.

The goal is not simply to obtain consent. It is to create a care plan that respects the patient’s preferences, supports their dignity, and gives everyone involved a clear understanding of how treatment will move forward.

If you are caring for someone who needs additional support receiving dental treatment, Blende Dental Group can help you understand the next steps and determine the most appropriate setting for care.
