One of my teeth in my lower jaw was loosed for years and it finally fell out. what can be done to fill that big space in my mouth?

Implant: See a dentist for an exam and discuss your treatment options. In many cases the best way to replace a missing tooth is with an implant. A dentist can evaluate your mouth and re maiming teeth to see if this can work for you. Other options may be a bridge or a partial denture.

Bone support: Teeth don't just fall out. Bone/gum support must be lost for this to happen. Often adjacent teeth also have support loss. If no bone, nothing to support implant or bridge/partial. How long has it been since your last Dental Exam? Please see Dentist for comprehensive evaluation and treatment plan rather than just a patch.

Implant and crown: If you are missing a single tooth, one implant and a crown can replace it. A dental implant replaces both the lost natural tooth and its root. The result is a tooth that looks and functions as close as possible to the one that you lost.

Several Options: A fixed partial denture (bridge), removable partial denture ("plate") or an implant-retained crown can be used to replace missing teeth. Consult with your dentist regarding the best option for your situation.
