Internal bleaching is a whitening technique used specifically for discoloured teeth that have had root canals. Unlike surface whitening, this treatment lightens the tooth from the inside out.
🦷 How It Works
- A small hole is made in the back of the tooth
- A bleaching agent is placed inside the tooth’s pulp chamber
- The hole is sealed temporarily while the whitening works over several days
- The process may be repeated before a final filling or restoration is placed
✅ Best Candidates for Internal Bleaching
- Teeth that have darkened after a root canal
- No signs of infection or structural damage
- Patients who want to avoid crowns or veneers
⚠️ Things to Know
- Only works on non-vital (root canal-treated) teeth
- Whitening is gradual and may require more than one visit
- Often followed by cosmetic restoration like bonding or a veneer
