When we talk about Alzheimer’s care, conversations usually centre around memory, medication, nutrition and safety. But Alzheimer’s oral care deserves attention too. For caregivers, something as simple as brushing teeth can become one of the most difficult parts of the day. As Alzheimer’s disease and dementia progress, patients may forget how to brush, spit or rinse, even when these were once familiar actions. They may clench their jaw, turn away or be unable to reliably spit out toothpaste or rinse. This makes it especially important to choose oral-care products that are safe if accidentally swallowed. For caregivers already managing meals, medication and changing moods, maintaining oral hygiene can easily become another daily challenge.

The Risks of Poor Oral Hygiene in Alzheimer's

For someone living with Alzheimer’s, keeping the mouth healthy can become difficult in ways that aren't always obvious. They may forget to brush, struggle to hold a toothbrush, become uncomfortable with certain textures or flavours, or simply lose interest in a task that once was effortless. Cognitive decline can make even familiar steps feel unfamiliar. This can allow plaque to accumulate, increasing the risk of tooth decay and periodontal disease. Medications and reduced saliva can also cause dry mouth (xerostomia), making the mouth feel uncomfortable and more prone to problems. The bigger challenge for caregivers is that a person with Alzheimer’s may not always be able to say, "My tooth hurts" or "My mouth feels dry." Instead, you might notice changes in behaviour, such as increased agitation, withdrawing from meals or becoming more resistant to brushing. These aren't necessarily signs of being difficult; they can sometimes be the only way discomfort is being expressed.
