Why Does Mint Make Your Mouth Feel Cold? A Dentist Explains the Science

That icy-cool feeling after brushing doesn’t mean your teeth are cleaner. It means your nerves were stimulated.

What Causes the Cooling Sensation?

Menthol activates TRPM8 receptors—your brain interprets this as cold, even without temperature change.

Does Mint Kill Bacteria?

Mint improves brushing experience but doesn’t replace mechanical plaque removal or professional cleaning.

Freshness vs Oral Health

Freshness is a sensation. Oral health is biology.

Dentist’s Perspective

Flavour supports habits—but hygiene depends on consistency, technique, and early gum disease detection.

Understanding the science behind everyday dental products empowers better choices and healthier mouths.

At our clinic, we believe patients deserve clarity, not marketing myths. Understanding how your mouth works helps you make better long-term decisions for your gum and dental health.
