Conventional whitening gels are not as effective on intrinsic stains.

These stains reside beneath your enamel and can have a number of causes.

Your dentist may recommend internal bleaching as a tooth whitening option for intrinsic stains.

Why is it called “internal” bleaching?

It is called internal bleaching because the bleaching paste is placed in the root and not on the tooth’s surface.

Your dentist performs a root canal, removing infected pulp, and placing a sodium perborate paste deep inside the tooth. The paste reacts with stains and dissolves them. Your tooth is checked 5-7 days later and if the treated tooth is still dark more paste is added. The bleaching process typically requires 3 sessions.

Once the desired colour is achieved, bleaching reaction is neutralised, and the tooth is sealed with a composite filling or partial crown.

Is internal bleaching more effective than other whitening treatments?

Other whitening treatments, such as teeth whitening gels, only treat the surface of your teeth. Internal bleaching helps lighten teeth that appear dark due to infection or damage.
