When is bone grafting necessary for dental implants?

If you have lost bone density, your jawbone may no longer be thick enough for an implant. When replacing your teeth with dental implants, a dentist will be surgically placing a small titanium post under your gums and securing it to your jawbone. As such, your jawbone must be dense enough to support the post. Think of it in the same way as if you were building a piece of furniture. The wood you were using would need to be thick enough for the screw. Otherwise, it would not be able to screw in all the way. A bone grafting procedure can increase the density of your jawbone so that the titanium post is a perfect fit.
