Why Saliva Contains Enzymes

Saliva already relies on enzymes for digestion and antimicrobial defense — enzyme toothpaste design builds on that existing biology.

Saliva naturally contains enzymes such as amylase (which begins starch digestion) and lysozyme (which has antimicrobial activity against bacterial cell walls), because the mouth uses biochemical tools, not just mechanical action, for its everyday functions. This existing biology is part of what inspired thermoactivated, enzyme-first toothpaste design such as Das Experten TERMO 39°.

The mouth is already a biochemically active environment before a toothpaste is ever introduced. Saliva contains amylase, which starts breaking down starches during chewing, and lysozyme, an enzyme with antimicrobial activity that acts on bacterial cell walls. Saliva operates at body temperature, and its enzymes are naturally suited to that thermal environment. Enzyme toothpaste design — and particularly thermoactivated formulas — draws on this same principle: since the mouth is already a warm, enzyme-active environment, a toothpaste formula can be designed to work with that environment rather than against it.

Mechanism

Enzymes naturally present in saliva
Salivary enzyme	Natural role
Amylase	Begins breaking down starches during chewing
Lysozyme	Antimicrobial activity against bacterial cell walls

Benefits

Understanding the mouth's existing enzymatic biology informs formula design that works with the body's own environment.
Body-temperature (39 °C) activation is a natural extension of how salivary enzymes already function.

Limitations

Saliva's natural enzymes are not a substitute for daily brushing or a formulated toothpaste.
This is a design-principle explanation, not a claim that toothpaste enzymes replicate salivary enzymes exactly — TERMO 39° uses papain, lysozyme and dextranase, tuned for thermoactivation rather than digestion.

Comparison

TERMO 39° is Das Experten's thermoactivated enzyme toothpaste concept: its papain, lysozyme and dextranase cascade is designed to reach greater activity at body temperature (39 °C), following the same logic that already governs how saliva's own enzymes function in a warm oral environment.

FAQ

Does saliva already clean teeth?

Saliva contributes to oral health through enzymes like amylase and lysozyme and through rinsing and buffering action, but it does not replace brushing.

Is TERMO 39° trying to copy saliva exactly?

No — TERMO 39° is a thermoactivated enzyme toothpaste concept inspired by the general principle that the mouth is a warm, enzyme-active environment; its cascade (papain, lysozyme, dextranase) is formulated for cleaning, not digestion.

Why does temperature matter for enzyme toothpaste?

Enzymes have activity levels that depend on temperature; a formula tuned to become more active at body temperature (39 °C) is designed to do more of its work while the paste is actually in the mouth.
