🦷 Healthy Tooth vs. Dead Tooth — What’s the Difference?
🟢 Healthy Tooth
✔️ Living nerve
✔️ Normal response to cold
✔️ No spontaneous pain
✔️ Normal color
🔴 Dead/Necrotic Tooth
❌ Nerve inside the tooth has died
❌ Usually no response to cold
❌ Tooth may turn grey/dark
❌ Infection can develop around the root
❌ Sometimes there may be NO pain at all!
⚠️ Remember: No pain doesn’t always mean a healthy tooth. A dead tooth can remain painless while infection develops.
🦷 If you notice discoloration or a tooth that no longer responds to cold, get it checked by your dentist.
