Regular whitening applies a whitening agent to the surface of teeth whose nerve is still alive. Walking bleach is a special whitening done from the inside. It is used on teeth that have lost their nerve and turned dark (non-vital teeth), for example because of past cavity treatment or an injury.
We make a small opening on the back of the tooth, place a high-concentration bleaching agent inside, and seal it. About once every few weeks, the agent is replaced at the clinic, and the tooth is whitened step by step until it regains an ideal whiteness that blends in with the healthy natural teeth around it.
Recommended for
- People who have just 1 tooth that looks unnaturally dark and who don't feel confident about their smile
- People whose tooth has had its nerve removed, so regular whitening did not make it whiter
- People who don't want a lot of their tooth ground down to fit a crown
