Is this fixable or is extraction necessary? If so, can I get an implant or only a bridge?
Just one look on at the x-ray tells me you have some bite issues. Your tooth is non-restorable, and needs to be extracted. You have two options. the best option , bone graft and placment of implant, and meanwhile have a removable temporary to cover the hole for the 6-8 months that it will take to complete the process. Option two is to extract and place a bridge. Having said that please look intot he bite issue, whatever you want to do, will fail if the bie is not corrected Good Luck
