If i get a dental implant for a front tooth, what takes the place of the missing space during healing if not having an immediate load or a flipper?

Healing cap: There will be a cover placed over the implant site called a 'healing cap.' it is essentially a man-hole cover for the gums to protect the implant (and gums) during the healing phase. If you choose not to use a flipper (during the healing phase) then, for all intents and purposes, you're choosing to have a space in your smile until the crown is completed.

Bonded tooth: A tooth, such as an acrylic denture tooth, can be bonded to the adjacent teeth for esthetics.(not function) ask your dentist if this would work in your situation.

Dental Implant Temps: In some cases a temporary implant abutment and crown could be made for esthetics. It is not to be used for function. If it is a back tooth sometimes it's best to just leave the space during the healing period.
