Why a healthy mouth helps older adults eat well
Missing teeth, sore gums and loose dentures quietly change what older people eat. Here is why that matters, and what families can do.

When chewing becomes difficult, people often switch to softer foods without noticing. Fresh fruit, vegetables, nuts and meat are slowly replaced by bread, rice and soups. Over months and years, that can mean fewer vitamins, less protein and less fibre, at a stage of life when good nutrition matters most.
What the research shows
Dr. Rifat co-authored a study on the link between oral health and nutritional status in adults over 65, published in the Journal of Prosthodontic Research. Research like this shows a clear link: people with fewer working teeth, or dentures that don’t fit well, are more likely to have a poorer diet.
Signs to watch for at home
- Cutting food into very small pieces, or avoiding certain foods
- Eating more slowly, or leaving meals unfinished
- Taking dentures out to eat
- Weight loss without a clear reason
What helps
- Regular dental check-ups, even for people with dentures or very few teeth.
- Fixing problems early: a sore spot or loose denture is usually easy to treat.
- Daily mouth care at home. Our caregiver guides show you how.
- Talking to us about dry mouth, which makes chewing and swallowing harder.
A comfortable mouth helps people keep enjoying their food, and their meals with family.
