What's behind it?

Mint is a genus of plants with over 20 species , ranging from peppermint to field mint. Mentha arvensis (field mint) is frequently used in dental care products. Its essential oil contains menthol – the substance that creates the typical cooling sensation on the tongue and gums . Even in demented mints , menthol is still present. oil The product still contains enough menthol . It only needs 20 ppm to produce a refreshing sensation .  Additionally The gentle freshness is enhanced by other ingredients, such as methyl acetate and limonene . supported (Lefingwell, 2009). This touch of freshness not only makes brushing teeth more pleasant, but also unconsciously gives us a feeling of cleanliness (Kamatou et al., 2013). 

Why is it relevant?

The flavor is more than just a nice bonus. Studies show that products with mint flavor are perceived as more beneficial (Dessirier et al., 2025). This can lead to you brushing longer and more thoroughly – a real plus for oral health (Roque et al., 2018). In addition, menthol stimulates saliva production . More saliva means better self-cleaning in the mouth and natural protection against cavities and gum problems (Kamatou et al., 2013).

Menthol tricks the brain : It feels cool because cold receptors are activatedbut in reality the temperature remains the same (Lasanen et al., 2016).

Scientific background

Menthol binds to so-called cold receptors (TRPM8) – tiny sensors in the mucous membranes. Your brain interprets the signal as cool, even though the temperature isn't actually dropping (Eccles, 2000). Studies in aroma research show that menthol has a mild antibacterial effect and can inhibit certain germs without disrupting the balance of the oral flora (Bacinska et al., 2025 & Adaszynka-Skwirzynka et al., 2025). This is precisely why modern products like the PeriTrap Microbiome toothpaste based on natural ingredients Mint oils – they provide freshness AND gentle support for the gums.
