I have two front teeth which have had root canal and crowns. Recently after several years one of them has an abscess, I've had antibiotics for 10 days. Been referred to endodontics to see if i am suitable for a apicoectomy.
I am nervous after watching a video of apicoectomy and hearing that it can cause the gum to shorten on surrounding teeth as well due to the procedure. But implants also have surgical intervention so I am not sure what to do?
Please advice, 
Thanks
