Implants offer firm support to man-made teeth. Single teeth attached to the implants, bridges or dentures won’t slip or switch in your mouth-a quite important benefit talking and when eating. This secure fit also helps man made teeth feel more natural than typical bridges or dentures. Many people may find implant-supported dentures more comfortable than dentures that do not use implants. Where teeth are missing, dental implants also help in keeping the jawbone from shrinking. Implants really are a great value, simply because they could last a lifetime with good care. Single Tooth Implants. The single tooth implant replaces the missing tooth’s roots. A single tooth implant is a standalone component and doesn’t include treating the teeth next to it.
