Animate this original artwork as a refined five-second website hero media asset. A narrow soft cyan light travels gently through the exact translucent tooth model, with restrained glass reflections. Preserve tooth silhouette, roots and internal layers. No growth, cracks or medical transformation. Preserve original identities, proportions, palette and materials. Locked camera unless explicitly specified. No zoom, cuts, text, UI, new objects or distorted anatomy. Continuous restrained motion; begin and end near the same composition where physically plausible.
