What is Dry Mouth (Xerostomia)? Understanding the Impact on People Living with Dementia

Dry mouth, also known as xerostomia, occurs when the mouth does not produce enough saliva to stay moist and comfortable. While it may sound like a small issue, dry mouth can have a significant impact on daily life — particularly for older adults and people living with dementia.

Saliva plays an important role in oral comfort and overall wellbeing. It helps with speaking, swallowing, tasting food, and keeping the mouth feeling fresh and hydrated. When saliva production decreases, the mouth can quickly become dry, uncomfortable, and sometimes painful.

Common Causes of Dry Mouth

There are many common causes of dry mouth in older adults and people living with health conditions. These can include:

• Certain medications

• Dehydration

• Cancer treatments such as radiotherapy

• Diabetes and other medical conditions

• Ageing

• Dementia and neurological conditions

Dry mouth in dementia care is often overlooked, despite the significant impact it can have on comfort, eating, drinking, and quality of life. Many people living with dementia may struggle to communicate oral discomfort or maintain regular oral care routines independently.

The Impact of Xerostomia on People Living with Dementia

Xerostomia can become painful, distressing, and uncomfortable. A persistently dry mouth can affect:

• Speaking clearly

• Swallowing food and drinks

• Taste and appetite

• Confidence and social interaction

• Hydration and nutrition

For some people, dry mouth can even lead to avoiding eating or drinking altogether because of discomfort within the mouth. This can increase the risk of dehydration, poor nutrition, and further oral health complications.

In dementia care, these challenges can become even more complex. When oral care feels uncomfortable or unfamiliar, it can cause frustration, anxiety, and distress for both the individual and their carers.

Supporting oral comfort is an important part of supporting dignity, wellbeing, and quality of life for people living with dementia.

How DentaBlue Supports Oral Comfort

At DentaBlue, we are passionate about improving oral comfort for people living with dementia and other health conditions.

DentaBlue is a soft, chewable oral comfort gummy designed to support individuals who may struggle with traditional oral care methods.

Through our testing and feedback, we found that DentaBlue’s unique formula supported the stimulation of saliva, helping to improve moisture and comfort within the mouth. The act of chewing, alongside carefully selected ingredients such as xylitol, can encourage saliva production and provide a fresher, more comfortable feeling for individuals experiencing dry mouth.

Some users also shared positive feedback around feelings of freshness and improved comfort after using DentaBlue, particularly within dementia care settings and at home with carers.

Supporting Comfort, Dignity and Quality of Life

Dry mouth is common in older adults and people living with dementia, but it should not be ignored.

At DentaBlue, our mission is simple: to support oral comfort, dignity, and quality of life in a compassionate and accessible way.

As conversations around dementia care, oral health, hydration, and wellbeing continue to grow, we hope to help families, carers, and healthcare professionals better recognise the importance of supporting oral comfort for vulnerable individuals.
