no implant is needed. just get cavity filled with composite. if u have pain in that tooth , in that condition xray is required to see caviy extension in that tooth.
Hi:From the photo it appears you might have a cavity at the gum line. If there is no nerve damage a simple tooth color filling will be the best option. Please make an appointment with a dentist as soon as possible before the cavity gets any deeper.Best,Dr. Maddahi
