Why have internal tooth whitening?

Traditional teeth whitening methods, such as laser whitening or home teeth whitening systems, are not effective on root filled teeth. Sometimes, a dentist may suggest porcelain veneers or crowns to hide the deep tooth discolouration. The problem with crowns and some porcelain veneers is that extensive irreversible tooth enamel reduction is necessary, which can be costly. However, internal tooth whitening and inside/outside tooth whitening techniques are available to tackle this problem effectively.

Internal Tooth Whitening

How is internal tooth whitening carried out?

During your assessment visit, our specialist endodontist will check the discoloured tooth and make sure it is suitable for internal whitening.

Using the dental microscope, we remove some filling and root filling material via the back of the tooth to create an access area for the whitening gel. The tooth will still look normal from the front. We then either place whitening gel directly over the root canal space (internal tooth whitening) or create a special whitening tray that has access to the inside of the tooth (inside/outside whitening).

After a week of internal or inside/outside whitening, we then reassess the tooth. Once the desired results are achieved, the access cavity is sealed using a bleach shade white composite filling.

How long do the results last?

Usually, this procedure will last for many years. Top-ups may be necessary from time to time. This could be every few years.

Whitening treatment risks

These kinds of whitening treatments (internal whitening and inside/outside whitening) do not always work. However, in the right hands, they are usually very successful treatments. It is always advisable to attempt an internal or inside/outside whitening procedure first before considering more invasive treatments like dental veneers or crowns. The whitening treatment preserves the precious tooth enamel.
