When Non-Food Items Go in the Mouth: A Calm, Step-by-Step Guide for Middle and Late Stage Dementia

It can be startling and worrying when your loved one puts a non-food item in their mouth. This behavior often stems from confusion, sensory seeking, or a brain that no longer recognizes objects correctly. The good news is that you can respond gently and effectively without panic or shame. This guide gives you concrete words to say, exact steps to take, and practical tools to keep everyone safe and calm.

Key points

  • Stay calm and do not scold — the behavior is caused by the disease, not defiance.
  • Use a gentle trade or redirection instead of trying to forcibly remove the item.
  • Offer safe, cold, or crunchy alternatives to satisfy the oral need.
  • Remove small, dangerous objects from the environment to prevent incidents.
  • Look for patterns: the behavior may signal hunger, thirst, boredom, or pain.
  • In late stage, focus on comfort and safety, not correction.

Why This Happens: The Brain Is Misreading the World

In middle and late stage dementia, the brain can lose its ability to correctly interpret what an object is. A washcloth might look like a piece of bread, a button like a candy, or a leaf like a cracker. As Dr. Camille Sinclair explains, the brain can trick a person into thinking a non-food item is actually food — mashed potatoes might appear as a dirty puddle, or spaghetti as a tangle of wires. This is not stubbornness or defiance; it is a neurological misperception.

Sensory Needs and Oral Exploration

For some individuals, mouthing objects is a way to explore the world, especially as other senses decline. It can also be a self-soothing behavior, similar to how a baby mouths a teether. In late stage dementia, the person may have lost the ability to use their hands skillfully (Teepa Snow notes that finger skills decline), so the mouth becomes a primary tool for investigation. The behavior may also be linked to hunger or thirst cues that the brain no longer registers, as Dr. Sinclair points out — the person may be seeking oral stimulation because their brain isn't signaling hunger properly.

It's Not About You — It's About the Disease

When you see this happen, it is easy to feel frustrated or embarrassed, especially in public. But remember: the person is not trying to be difficult. Their brain is simply misfiring. The Dementia Careblazers remind us that if the person is pleasantly engaged in something, even if it's mouthing a safe object, we don't need to correct them. Our job is to redirect gently, not to scold. The goal is to keep them safe while preserving their dignity and sense of joy.

Step-by-step

  1. Stay calm and do not react with alarm — take a slow breath.

  2. Approach from the front at their eye level, use a warm neutral tone, gently extend your open palm near their chin, and say: 'Let me take a look' or 'Here, let me hold that for you.'

  3. Offer a safe oral alternative — a cold wet washcloth, popsicle, ice chip, or sugar-free hard candy (if swallowing is safe).

  4. If the item is already in their mouth, do not try to fish it out with your fingers; calmly offer a drink of water or a bite of soft food (like applesauce) to help them swallow it safely or spit it out.

  5. Once the item is out, remove it from sight without fuss — slip it into your pocket or a nearby bin — and redirect their attention to a different activity or safe snack.

  6. If the behavior repeats, look for patterns (time of day, boredom, hunger, thirst, or tiredness) and address the underlying need with a snack, drink, walk, or sensory activity like folding towels.

  7. If the item is dangerous (button battery, sharp object, or toxic substance), stay calm but act fast: use a finger sweep only if you can clearly see the item; otherwise call 911 or poison control immediately.

What not to do

  • Do not say 'No!' or 'Stop that!' in a sharp voice — use calm redirection instead.

  • Do not yank the item out of their mouth or grab their jaw — offer a trade or a drink so they release it voluntarily.

  • Do not lecture or explain why the item is not food — their brain cannot process that logic; just redirect.

  • Do not punish or take away privileges — this is a symptom of the disease, not a behavior problem.

  • Do not ignore a choking hazard or toxic item; for safe items (e.g., a clean washcloth), it is okay to let them mouth it briefly if they are calm and happy.

  • Do not assume they are hungry or thirsty — they may be seeking sensory input; offer a variety of safe oral options (cold, crunchy, chewy) to find what they prefer.

Practical tools

  • The 'Trade' Phrase

    Keep a few safe, mouthable items in your pocket. When you see a non-food item, say calmly: 'Let me trade you. Here, try this cold washcloth / popsicle / teether.' Offer it with an open palm and wait.

  • Cold Sensory Kit

    Prepare a small container with a cold wet washcloth, a chilled spoon, a popsicle, and ice chips. Cold sensations soothe and redirect oral exploration.

  • Visual Cue: Colored Washcloth

    Use a brightly colored washcloth (red or blue) to signal 'this is for your mouth' — a positive visual cue. A child-safe teether in a bright color works the same way.

  • Environment Scan Routine

    Before meals or activities, quickly scan the area for small tempting objects: buttons, coins, leaves, pet toys, craft supplies, or small batteries, and remove them from reach.

Discuss with your clinician

If the person frequently swallows non-food items (pica), ask the doctor about a referral to a speech-language pathologist for a swallowing assessment.

If the behavior is new or worsening, rule out a dental problem, mouth pain, or a medication side effect that might be causing the person to seek oral relief.

If the person has a history of choking or aspiration, ask about safe food textures and whether thickened liquids might be needed.

If the behavior is accompanied by weight loss or refusal to eat, discuss with a dietitian or doctor about nutritional supplements or alternative feeding strategies.

If the person is on medications that affect swallowing or alertness, review with the prescriber whether adjustments might help reduce the behavior.
