Dentures are becoming less used in dentistry, primarily because people
are keeping their teeth later into life.  But dentures still have their place.  
Their are two main types of dentures, partials and full dentures.  Partial
dentures are to replace some missing teeth in an arch where there are
still some natural teeth.  A full denture is a replacement of all of the
teeth on an arch.  Dentures take many appointments to make, because
different steps require trying in the denture.  Then after the denture is
made, a few adjustment appointments may be necessary.  Now it is also
possible to have
implants placed that help to hold in dentures.
