Dry Mouth → Cavity Risk 3D

The real salivary-buffering chain, rendered as a genuine 3D gland → duct → oral pool → tooth system you can orbit around.

Fluoride / remineralization support 0%

Saliva flow particle

Bicarbonate buffer ion

Calcium / phosphate ion

Critical pH threshold

Caries lesion

Dry Mouth & Cavity Risk — 3D Salivary Buffering Simulator

The same causal chain from reduced salivary flow to accelerated caries as the 2D lab, rendered as a real 3D gland, duct, oral pool and tooth you can orbit around, with a live 3D pH (Stephan curve) graph and demineralization gauge floating beside the model.

0.3-0.4 mL/min: normal unstimulated salivary flow
<0.1 mL/min: clinical dry-mouth (xerostomia) threshold
pH 5.5: critical threshold below which enamel begins dissolving
3-5×: caries risk increase in clinically dry mouths

Drag to orbit the camera and scroll to zoom. Salivary flow reduction and sugar exposure frequency drive the same buffering-capacity and caries-rate formulas as the 2D version; a fluoride / remineralization slider adds the clinically documented effect of fluoride slowing demineralization without altering the underlying salivary pH chemistry.
