Know every tooth, cold.
The permanent dentition, charted the way you face it in the chair. We give you a Universal number or a tooth name and you tap the tooth — or we light a tooth up and you pick its number. Orientation is clinical: the patient's right is on your left, so you build the instinct, not just the memory.
- ✓Universal system, both arches. All 28 teeth in view — 2 through 31, in correct clinical orientation.
- ✓Three ways, mixed. Number → tap the tooth, name → tap the tooth, and tooth → pick the number. You have to know it every direction.
- ✓Feeds your dashboard. Your score rolls into your Scientific readiness.
Why it starts at 2: the third molars — 1, 16, 17 and 32 — aren't in this view (they're the wisdom teeth, often absent). This drill locks in the 28 teeth actually in front of you.

This drill is a study aid using the Universal Numbering System for the permanent dentition, shown on a full-arch view in standard orientation (as you face the patient, the patient's right is on your left). It covers the 28 teeth in view; the third molars (1, 16, 17, 32) are not shown. It builds numbering and tooth identification, not clinical diagnosis.
