Internal Tooth Whitening

Internal tooth whitening is a particular type of teeth whitening treatment that is specially designed for a discoloured front tooth which has previously had a root canal treatment.

Unlike home teeth whitening, internal teeth whitening is only suitable for very specific cases of tooth discolouration; your dentist will help you discover if it is the right treatment for you.

Internal tooth whitening treatment explained

Your dentist will firstly very carefully assess your tooth to make sure that the type of discolouration is suitable for internal tooth whitening.

Prior to your internal tooth whitening treatment, an X-ray of the tooth will make sure that the root canal filling is of a high quality as it is vital that a good seal between the top of the tooth and the root is in place for internal tooth whitening to be appropriate.

A photograph of your tooth will be taken and a shade guide used to correctly judge the shade so that your internal tooth whitening treatment can return the best possible results.

Once your dentist is satisfied that the tooth is a suitable candidate for internal tooth whitening, a small hole will be created in the back of your tooth and the top of the root canal filling exposed. An impervious lining will be placed over this and then a special whitening gel will be carefully placed into the tooth. A tooth coloured filling material will be used to close the hole.

After internal tooth whitening treatment

Normally your dentist will assess your tooth one or two days after your internal tooth whitening treatment. It is common for the gel to require replacement two or three times to achieve the required whitening effect. In some cases it is not possible to completely lighten the tooth to match its neighbours. Your dentist will discuss other treatment options with you if this is the case.

Once your tooth is whitened, a light tooth coloured permanent filling will be placed in the hole to seal the tooth. Make an appointment to discuss internal tooth whitening with one of our dentists today.
