What Your Mouth Reveals About Your Health with Eimear Mithen #153

🎧 Episode Description

Laura is joined by dental hygienist Eimear for a clear, practical conversation about oral health and why it connects to the rest of the body, not just your teeth. They talk about plaque, tartar and gum disease, what causes bleeding gums, and why brushing your teeth without brushing your gums misses half the problem.

Eimear explains why interdental brushes work better than floss for most people, how electric toothbrushes remove far more plaque than manual ones, and why soft brushes are better than hard ones. She also talks about mouth breathing, tongue scraping, night guards for grinding, and what happens when plaque is left to harden under the gums.

The conversation then moves into some of the less expected links between oral health and things like menopause, pregnancy, arthritis, diabetes and cancer treatment. Throughout it all, Eimear keeps coming back to prevention, showing how small, realistic habits can reduce risk and protect your teeth and gums over the long term.

🔑 Key Points

Most people are not cleaning where it matters most

Bacteria sits along the gumline and between the teeth, which is why brushing only the visible surfaces leaves disease behind.

Plaque becomes harmful when it is left too long

Soft plaque hardens into tartar and creates a protected space where more aggressive bacteria can grow and damage gums and bone.

Tools matter more than people realise

Electric toothbrushes and interdental brushes remove far more bacteria than manual brushing and flossing.

Saliva plays a major role in oral health

Dry mouth, common during menopause, illness and medication use, changes the balance of bacteria and increases the risk of decay and gum disease.

Gum disease is not just a mouth problem

Inflammation and bacteria are linked with conditions like diabetes, arthritis, pregnancy complications and Alzheimer’s.

Grinding and clenching cause real damage

Night-time grinding can shorten teeth, irritate gums and strain the jaw.

Consistency beats perfection

Regular, simple habits protect the mouth better than occasional intense cleaning.
