Internal tooth bleaching before after

Internal bleaching lightens a darkened root-treated tooth from inside the crown after the dentist checks its seal and cause of discoloration.

Internal bleaching treats discoloration within a non-vital or root-treated tooth, where pigments inside dentine remain after pulp injury, bleeding, or some root-canal materials. A clinical examination separates these possibilities.

The dentist examines the tooth, reviews or takes a radiograph, checks the root filling and restoration, protects the root-canal entrance, places bleaching gel inside the access cavity, and seals it between visits. Arrange an examination if the problem persists or worsens.

Arrange assessment before bleaching if the tooth is painful, leaking, cracked, has gum swelling, or its colour changed after recent trauma, because the cause may need treatment first. Do not wait if swelling affects swallowing or breathing.

Ask whether the root filling and cervical seal are sound, what material will be placed, how the shade will be assessed, and whether a crown or veneer is needed afterward. Ask what the examination shows and what alternatives are reasonable.
