Last year, two front teeth had root canal treatment, and now they want to have porcelain teeth. The root of the right tooth has a shadow, and the doctor said that root canal treatment must be done again. First of all, please upload X-rays.

Secondly, in principle, in order to prevent long-term root canal problems, leading to porcelain crown loss or tooth loss, try to do root canal treatment again. However, if the focus is limited or asymptomatic, in order to prevent the problem you mentioned, it is difficult to take out the original filler for root canal treatment, and there are many tissue injuries, so you can consider not doing it again.

However, since we haven't made porcelain crowns yet, we are going to make porcelain crowns. It's like laying a foundation in Gai Lou. It is best to get rid of the loose foundation and start over.

The problem you are worried about is also the problem that doctors are worried about, or the problem that needs attention. The doctor will definitely remove the original filler and do root canal therapy again while preserving the original tissue as much as possible.

As long as you do it again, you can generally ensure that you will not fall off when grinding your teeth.
