A dental implant is a titanium post that is surgically positioned into the jawbone beneath  the gum line that allows your dentist to mount replacement teeth or a bridge into that  area. An implant doesn’t come loose like a denture can. Dental implants also benefit  general oral health because they do not have to be anchored to other teeth, like  bridges.
Because implants fuse to your jawbone, they provide stable support for artificial teeth.  Dentures and bridges mounted to implants won’t slip or shift in your mouth — an  especially vital benefit when eating and speaking. This protected fit helps the dentures  and bridges as well as individual crowns placed over implants, feel more natural than  conventional bridges or dentures.
For some people, ordinary bridges and dentures are simply not comfortable or even  possible, due to sore spots, poor ridges or gagging. In addition, ordinary bridges must  be attached to teeth on either side of the space left by the missing tooth. A benefit of  implants is that no adjacent teeth need to be prepared or ground down to hold your new  replacement tooth/teeth in place.  To receive implants, you must have healthy gums and adequate bone to support the  implant. You must also commit to keeping these structures healthy. Meticulous oral  hygiene and regular dental visits are critical to the long­term success of dental implants.
