What is the direct answer?
A badly decayed tooth may have exposed dentine, an infected pulp, sharp edges, or a root that still needs treatment.
What does this question mean?
Tooth decay removes enamel and dentine through bacterial acid damage. A collapsed visible crown does not show whether the pulp, root, or surrounding bone is infected.
What can you do next?
Keep the area clean, chew on the other side, and do not put aspirin or chemicals on the tooth. A dentist may restore it, perform root canal treatment, or extract it if it cannot be repaired.
When should you seek dental care?
Arrange prompt care for swelling, fever, pus, worsening pain, or a bad taste. Breathing or swallowing difficulty is an emergency.
What should you ask the dentist?
Ask whether the tooth is restorable, whether the pulp is infected, and which examination and radiograph are needed.
