Is it uncommon to have an extraction and dental bone grafting if there is an infection there? (Photo)

I currently have a infection at pulp of tooth on number 9 . They say those don’t actually go away with antibiotics . The tooth would need to be removed . Iam looking at getting implant. My question is that is it uncommon they want to extract tooth and do dental bone grafting even tho there is the infection in there . ? My thought is I figured they would want you to get it out clear infection then later do bone grafting . They say no. They typically can do it at time of extraction
