What will happen if i don't get a dental implant?

Teeth could shift: Teeth that shift will not occlude correctly, resulting in an inefficient bite. This will put additional stress on your other teeth. The shifting, tilted teeth can end up with periodontal bone loss. Supererupted antagonist teeth may result in occusal prematurities. Consider replacing the missing tooth.

Bone loss: After a tooth is removed, the most obvious result is a gap in your smile. Less obvious is the loss of chewing ability. While these are serious issues to consider, a potentially bigger problem lies hidden beneath the gum call bone loss. Without your teeth and bone loss, your face will begin to look prematurely aged. The good news is that tooth replacement with dental implants help prevent bone loss

Depends: What is the implant for -- missing tooth/teeth, holding in a denture?? If tooth or teeth, then you will not have them replaced unless you go to removable prosthesis. If denture, then it will not be as stable. Without implant, the bone will deteriorate faster (resorb) than with one. Ask your Dentist or Prosthodontist. Good Luck.
