Tooth sensitivity, solved at the source.
If cold drinks make your patients wince, here's why Er:YAG laser desensitization is changing the conversation:
Seals tubules at the source — not a coating that wears off
2,940 nm wavelength — absorbed by water 10,000x more than Nd:YAG, so energy stays at the surface
No needles. No drill. No vibration.
~2 minutes of chair time per area
Long-lasting relief documented out to 6 months in clinical studies
Minimal collateral damage — safe for the pulp at appropriate settings
Naturally bactericidal — a bonus for cervical lesion cases
Conventional pastes and varnishes mask the symptom. Er:YAG addresses the mechanism — sealing the dentinal tubules so the fluid movement that triggers nerve pain can't happen.
Faster appointments. Calmer patients. Results that hold.
