The short answer
After a root canal, the tooth and nearby tissues may feel tender when biting while inflammation settles. A persistent flare, swelling, severe pain, or a loose temporary filling needs review because it may indicate an untreated canal, leakage, crack, or another problem.

What is the direct answer?
What does this question mean?
Root canal treatment removes inflamed or infected pulp, cleans the canal system, and seals it with a filling material. Short-term tenderness can result from manipulation of tissues around the root; later problems can arise if sealing, restoration, or tooth structure is compromised.
What can you do next?
Follow the dentist's eating and medication instructions, avoid chewing hard foods on a tooth with a temporary filling, and return for the planned permanent restoration. Keep brushing and cleaning between teeth gently.
When should you seek dental care?
Contact the treating dentist for increasing pain, swelling, fever, a bad taste, a bite that feels high, or a temporary filling that falls out. Trouble swallowing or breathing requires emergency care.
What should you ask the dentist?
Ask what symptoms are expected in your case, when the permanent crown or filling should be placed, and whether the tooth has a crack or missed canal. Ask how to protect it during healing.
