Why Do Fizzy Drinks Tingle in Your Mouth?
The bite of carbonation includes a chemical sensory response, not merely bursting bubbles. Carbonic anhydrase contributes to that chemistry. In controlled human studies, bite persisted when bubbles were suppressed, although bubbles could change its strength.

What the illustration shows
Navy and gold educational poster titled “Why Do Fizzy Drinks Tingle in Your Mouth?” A mouth thumbnail points to a large cutaway of layered peach oral lining beneath blue liquid. Small blue dots represent dissolved carbon dioxide; larger spheres are labeled bubbles. A branching gold sensory ending lies within the tissue, with a rightward arrow labeled “Signals toward the brain.” A separate strip links dissolved CO2, chemical activation and sensory signals, noting that carbonic anhydrase helps this chemistry and that the diagram is not a molecular map. A bottom panel says bite remained when laboratory studies suppressed bubbles, while bubbles can still change its strength. Gold AllHumanBody.com and “REAL ANATOMY. REAL KNOWLEDGE. A HEALTHIER TOMORROW.” finish a flat navy footer.
How to interpret this poster
- Not a complete molecular map or exact human enzyme location. Small experimental studies; no beverage-health or provocation advice.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
