How to Tell if a Tooth is Dead: Key Signs to Look For


Recognizing a dead tooth is crucial for timely dental care. If you suspect a tooth is dead, look for these key signs:

  • Discoloration: A dead tooth often appears discolored compared to surrounding teeth, turning gray or black.
  • Pain: Persistent pain or a dull ache could indicate the tooth’s nerve is dying or already dead.
  • Swelling and Abscess: Swelling around the gum line and the presence of an abscess indicate infection and a likely dead tooth.
  • Bad Breath: A foul odor from the mouth or bad taste can be a sign of decay within a dead tooth.
  • No Sensation: Lack of sensitivity to hot or cold foods suggests the tooth’s nerve is no longer functioning.

If you identify any of these signs, consult your dentist for an accurate diagnosis and appropriate treatment.
