Most people don't feel uncomfortable and their bones don't hurt. However, if the posterior teeth are to be implanted, the implanted titanium nail is very close to the mandibular nerve canal, which may compress the nerve and cause pain. Of course, because of the improvement of imaging technology (I don't know if you have done CBCT) and preoperative design, this situation has rarely appeared. Even if it appears, there will be a solution, so don't worry about the pain.

It's very convenient to use, just like a real tooth, but be careful not to bite too hard, because it's not as sensitive as a real tooth, and sometimes it's no problem to implant a tooth, but it shows the real tooth.
