Internal tooth whitening
After root canal treatment, it is not unusual for a tooth to darken
gradually and take on a greyish shade, different from its neighbours.
Internal whitening can often restore a shade close to the original one,
without resorting to a veneer or a crown.
How internal whitening works
Unlike conventional whitening, which acts from the outside of the tooth, internal whitening involves placing a whitening agent inside the root-treated tooth, in the pulp chamber, which has first been cleaned and sealed. It is a targeted technique, reserved for teeth that have already had root canal treatment.What results to expect
The outcome depends on several factors specific to each patient: the discolouration being treated, how long it has been present and the initial colour of the tooth. In the great majority of cases the results are very satisfying and are visible from the very first session.
The result depends on the individual patient — a first appointment allows the
discolouration to be assessed and the expected result estimated.
Maintaining the result over time
To preserve the lightening achieved, top-up sessions may be offered if the clinician judges them necessary, particularly if the tooth tends to grey again over time.Why choose this approach?
- it avoids sacrificing healthy tooth structure, unlike a veneer or a crown;
- treatment is targeted on the single tooth concerned;
- the result is visible from the first session;
- it is a lasting solution, with simple maintenance if needed.
