Sometimes teeth roots may be retained underneath a partial or full denture called an ‘overdenture’, in order to maintain bone to help support the denture. It’s important that these roots are kept clean, otherwise they’ll decay rapidly or gum disease will develop.

The roots may need to be root-canal-treated in order to cut the teeth close to the gums, or have fillings or root caps inserted. In other cases the natural teeth may be worn so heavily that we can just place the denture over them. It’s also possible to have attachments put in the root caps to help hold the denture in place or to construct overdentures with implants underneath – see implant overdentures.

Overdentures are considerably more complicated to make than conventional dentures and therefore cost more. They can be also a bit more bulky, due to the roots sitting underneath.
