Non-vital tooth bleaching is a dental treatment used to lighten a tooth that has become dark after root canal treatment. When a tooth is no longer “vital” (the nerve has been removed), it can change color from the inside. Unlike normal whitening, this treatment works from inside the tooth, not just on the surface.

Your dentist may recommend this treatment if: • The tooth has had a root canal treatment • The tooth appears grey, brown, or dark yellow • The discoloration affects your smile or confidence • The tooth structure is otherwise healthy and restorable • You want a conservative option instead of veneers or crowns ⚠️ It is not recommended if: • There is active infection • The root canal filling is poor or leaking • The tooth has cracks or large fractures • There is significant loss of tooth structure

Common reasons include: • Breakdown of blood products inside the tooth • Old root canal materials • Trauma to the tooth • Previous dental treatments • Aging of internal tooth tissues

The procedure is usually painless and done over 1–3 visits. Step-by-Step: 1. Assessment X-ray to confirm the root canal is healthy Shade recorded for comparison 2. Access Opening A small opening is made in the back of the tooth 3. Protective Seal A protective barrier is placed over the root canal filling to protect the root 4. Bleaching Agent Placement Whitening gel is placed inside the tooth 5. Temporary Seal The tooth is temporarily sealed The whitening agent is left inside for several days (This is often called the “walking bleach” technique) 6. Review Appointment Shade is checked Bleaching may be repeated if needed 7. Final Restoration Once the desired color is reached, the tooth is permanently sealed ⏱️ Each appointment is usually short (30–45 minutes).

After treatment: Your dentist will monitor the tooth color A final permanent filling is placed Regular dental check-ups are important 🦷 You should: Maintain good oral hygiene Avoid biting hard objects with the treated tooth nform your dentist if you notice pain or color changes

Results can last many years Some teeth may slowly darken again over time Touch-up bleaching may be possible if needed

Non-vital bleaching is generally safe, but possible risks include: Temporary sensitivity (rare) Uneven color compared to neighboring teeth Color relapse over time External cervical resorption (very rare, but serious) Risk is minimized by proper technique and protective sealing Your dentist takes precautions to reduce these risks.
