hand-under-hand for mouth and oral care
Key points
- Hand-under-hand gives the person a sense of control and reduces resistance during mouth care.
- Use an empty spoon or straw to cue the mouth to open naturally, rather than prying it open.
- Keep the person’s other hand busy with a washcloth or small object to reduce grabbing and pushing.
- In late-stage dementia, the main goal is mouth comfort and moisture, not perfect brushing.
- Approach from the front, at eye level, and give one step at a time to avoid overwhelming the person.
- Always consult a clinician before using any product that could be swallowed, such as mouthwash or toothpaste.

Step-by-step
Before you begin, gather everything you need: a soft toothbrush (or a moistened gauze pad or oral swab), a small cup of water, and a towel to catch drips. Set them within easy reach so you do not have to leave the person’s side.
Approach the person from the front, at eye level, and use a calm, warm voice. Say something like, ‘Let’s take care of your mouth together. I’ll help you hold the brush.’ Avoid asking ‘Do you want to brush?’ as this invites refusal. Instead, use a collaborative statement like ‘Let’s do this’ or ‘Time for a little mouth freshening.’
If the person is seated, sit or kneel so you are at their level. If they are in bed, raise the head of the bed if possible. This reduces the power dynamic and makes the task feel more like teamwork.
Offer the person something to hold in their other hand—a washcloth, a book, or a small object. This keeps their hands busy and reduces the urge to push you away. It also channels their focus away from the mouth care task.
Now use hand-under-hand: place your hand under the person’s hand, palm up, and gently place the toothbrush or oral swab between their fingers and your palm. Guide their hand slowly toward their mouth. If they resist, pause and wait. Do not force the movement.
If the person does not open their mouth, try using an empty spoon or a straw. Bring it gently to their lips, as if offering a sip or a bite. Their brain may interpret this as a familiar cue for eating or drinking, and they may open their mouth spontaneously. Once open, you can slide the toothbrush or swab in.
Once the mouth is open, focus on the front of the mouth first. Gently brush or wipe the teeth and gums in a circular motion. If the person clenches down, do not try to pry the mouth open. Instead, stop, wait, and then try again with a different cue—like touching the lips with a wet cloth.
If the person is able to spit, encourage them to do so by saying, ‘Let’s let the water out.’ If they cannot spit, use a suction toothbrush or gently wipe the excess saliva away with a cloth. The main goal is to keep the mouth moist and free of food particles.
After brushing, offer a sip of water from a cup or a straw, if the person can swallow safely. If there is a risk of aspiration, use a moistened oral swab to wipe the inside of the cheeks and tongue instead.
End the session with a positive, reassuring comment like, ‘You did a great job helping me. Your mouth feels so fresh now.’ Then remove the tools and give the person a moment to relax.
What not to do
Do not try to pry the mouth open with your fingers or the toothbrush. This can cause pain, fear, and a stronger clench. Instead, use the empty spoon or straw cue to trigger a natural opening.
Do not give multiple instructions at once, like ‘Open your mouth, tilt your head, and spit.’ This overwhelms the person’s processing ability. Give one step at a time: first ‘Let’s hold the brush,’ then ‘Let’s bring it to your lips,’ then ‘Let’s open.’
Do not stand behind the person to brush their teeth if they are in late stage. This can feel like an attack. Always approach from the front, at eye level, so the person can see you and feel safe.
Do not use flavored toothpaste or mouthwash without checking for swallowing risk. If the person may swallow, use plain water or baking soda toothpaste instead. Consult the dentist or doctor before using any rinse.
Do not rush the process. If you are in a hurry, your tension will transfer to the person. Allow at least 10–15 minutes for mouth care. Slow down, breathe, and treat it as a shared activity rather than a chore.
Practical tools
The empty spoon or straw cue
Keep a clean, dry spoon or a straw nearby. Before bringing the toothbrush to the mouth, gently touch the spoon or straw to the person’s lips. Their brain may interpret this as a cue for eating or drinking, and they may open their mouth reflexively. Once open, you can slide the toothbrush or oral swab in. This is especially useful when the person is clenching or turning away.
Something to hold in the other hand
Offer the person a small washcloth, a soft book, or a textured object to hold in their free hand. This keeps their hands occupied and reduces the likelihood of them grabbing the toothbrush or pushing you away. It also gives them a sense of purpose and control. Say something like, ‘Can you hold this for me while we brush?’
Moistened gauze pad or oral swab
If a toothbrush is too threatening, use a piece of moistened gauze wrapped around your finger (under the person’s hand) or a soft foam oral swab. Gently wipe the inside of the cheeks, gums, and tongue. This is less invasive and can be more acceptable in late-stage dementia. It also helps remove food debris and keep the mouth moist.
Suction toothbrush (discuss with clinician)
For people at high risk of aspiration, a suction toothbrush that removes saliva and toothpaste as you brush can be a game-changer. Discuss this with the person’s dentist or doctor to see if it is appropriate. It reduces the risk of choking and makes mouth care safer.
Baking soda toothpaste or plain water
If there is a concern that the person may swallow toothpaste, use a small amount of baking soda toothpaste (which is safe to swallow) or simply use plain water on the toothbrush. Avoid anti-plaque rinses unless the doctor or dentist has cleared them, as they can be harmful if swallowed.
Discuss with your clinician
Ask the person’s dentist or doctor about using a suction toothbrush if there is a high risk of aspiration.
Consult with a clinician before using any anti-plaque rinse or mouthwash, especially if the person may swallow it.
If the person has dentures and is unable to remove them, ask the dentist for guidance on how to clean them safely without causing discomfort.
Discuss the use of saliva substitutes or oral moisturizers if the person’s mouth is chronically dry, as some products may be safer than others.
