Hi there I just got my crown placed today on my implant site and feel like my gum line is too low. It is not symmetrical with the tooth on the other side of my mouth and is noticeable from the front when I smile. My dentist briefly mentioned in the chair that the gumline would recede a tiny bit with time. Can anybody verify this? I've been having trouble finding my exact concern on the Internet. Is there any other procedure or option? I should ask for when I visit him next.?
