Careful with Internal bleaching

If you have a tooth that had a previous root canal treatment and it's getting discolored, sometimes with a range of colors from grey to brown, sometimes even pink when the dentist left some live pulp inside the tooth, there's a good option to put that tooth with again, and that is Internal Bleaching.

So what do you do?

You drill the tooth through the same it was drilled to do the treatment and you protect it 2mm under the CEJ line with Glass Ionomer. You put the Hidrogen Peroxide in the pulp chamber and you close it for 3 to 5 days. Check the results and repeat if necessary.

So... All seems pretty easy and pretty good, and in fact the tooth get much whiter but the problem is that in clinical trials have showed that this kind of treatment has a recidive rate of aobut 50%, which means that after 3 years half the internal bleachs get back to dark again... Although it's never as the original dark color but it gets darker and you may need to internal bleach the tooth again so...

Should you go for internal bleaching? Or just solve the problem with a Ceramic Crown?

I don't have the answer to that, it depends on many factors, so you should be aware of this before choosing the treatment you want...
