Hi,
You shouldn’t be able to see the thread of the implant post or have soreness around that area after eating. It might be possible that some type of gum or bone graft could solve this issue, but I’d ask your oral surgeon why this problem has developed, how the graft will work and why he originally suggested removing the implant and replacing it. Alternatively, seek a second opinion before you have nay more work carried out on this implant.
Best regards,
Ali
