Hello, One of my

Hello,

One of my teeth top right 3rd from the back has 2 fractures less than 1cm apart which is causing it to wobble. i went to one of those walk-in dentists and the dentist said that the whole tooth has to be extracted. I asked why it was not possible to pull back this part of the tooth that wobbles, put some bonding material onto it and then push it back so that it sticks to the main body of the tooth and then seal the fractures up and also to put a crown on if necessary. She said it was not possible because the fracture go below the gumline. Is this the be on and end all in that once a fracture goes below the gumline the tooth has to be extracted.

Thank you
