Your grandmother’s behavior of rubbing toothpaste on furniture is likely related to her dementia. This condition can cause unusual behaviors that may seem strange or confusing to others[1][3].
As dementia progresses, it affects memory, thinking, and behavior. Your grandmother might be experiencing confusion about the purpose of objects or how to use them correctly[1]. She may have forgotten what toothpaste is for or mixed up its use with furniture polish.
People with dementia often have trouble recognizing everyday objects and understanding their functions[4]. This can lead to using items in unexpected ways, like applying toothpaste to furniture instead of teeth.
Another possibility is that your grandmother is experiencing a symptom called “pica,” which involves eating or mouthing non-food items[7]. While toothpaste isn’t typically eaten, the urge to interact with inedible substances could explain her behavior.
Dementia can also cause repetitive behaviors or actions that may not make sense to others[1]. Your grandmother might find the act of rubbing toothpaste soothing or believe she’s performing a necessary task.
It’s important to approach this situation with patience and understanding. Your grandmother isn’t doing this on purpose to cause trouble. Her brain is changing, affecting her ability to think and behave as she once did.
To help manage this behavior, try gently redirecting her attention when you notice it happening. You could offer her a safe, engaging activity as an alternative. It’s also a good idea to store items like toothpaste out of easy reach to prevent misuse.
Remember, this behavior is a symptom of her condition, not a reflection of who she is. Providing a calm, supportive environment can help reduce confusion and anxiety that might contribute to such actions.
If you’re concerned about this or other unusual behaviors, it’s best to consult with her doctor. They can provide guidance on managing symptoms and ensuring your grandmother’s safety and comfort.
