What is the direct answer?
Internal bleaching cost varies with diagnosis, prior root canal treatment, visits, sealing, and the final restoration.
What does this question mean?
Internal bleaching lightens a discoloured non-vital tooth from inside the crown. A dentist opens the access area or existing restoration, places peroxide-based material in the pulp chamber with a protective seal, and reviews the shade before restoring the tooth.
What can you do next?
Ask for an itemised plan covering examination, imaging, isolation, removal of old material, bleaching appointments, temporary sealing, and the final restoration. The diagnosis must be confirmed first because bleaching is not a substitute for treating decay, leakage, or failed root canal work.
When should you seek dental care?
Arrange assessment for a dark tooth with pain, swelling, a loose restoration, or a history of trauma. Urgent review is needed for facial swelling, fever, or difficulty breathing or swallowing.
What should you ask the dentist?
Ask what is included in the estimate, whether the root canal needs assessment, which material will seal the access, and whether a filling or crown is needed afterward.
