Modern dental treatment can save teeth that were routinely extracted decades ago.  However, you may have a badly decayed or fractured tooth that needs to be extracted or pulled out.  Don’t just have the tooth pulled out without a plan.  Will you replace that tooth with a bridge or implant?  Is the tooth a front tooth?  If the tooth that needs to be pulled out is a front tooth, speak to your dentist about possible ridge collapse after the extraction.  Teeth are held in place inside bone called alveolar ridge.  Alveolar ridge is a functional structure.  In other words, if there are no teeth in the ridge, the ridge (the bone inside the ridge) will gradually resorb.  You will see the ridge getting thinner over time.

soft-tissue-aug-1When a tooth has been missing for a long time, the ridge will look very thin and short.  However, this ridge resorption can occur rather rapidly in cases involving front teeth.  When a back tooth is extracted, the remaining walls of the sockets are usually quite thick and will last long enough for bone to fill the extracted socket where the tooth used to be.  When a front tooth is extracted, the thin outside bone, or bone wall on the outside, will resorb too quickly for bone to fill in the extracted socket.  The result is that the outside of the ridge will collapse.  When a bridge is made over this collapsed area of ridge, the fake tooth (pontic) will need to be made longer and will affect the smile.  When an implant is planned in the area, there may not be enough bone to receive an implant, making a grafting procedure necessary.

There may be a reasonably simple way to prevent this ridge collapsing seen after the extraction of a front tooth.  If the outside bony wall of the socket is thin and is likely to resorb quickly, a socket preservation procedure may be done to prevent the ridge collapsing.  Only your dentist can tell if a socket preservation is needed with some special radiographs or by visual exam right after the extraction.  Socket preservation procedures are usually done immediately after the extractions.  Remember that socket preservation procedures are not always necessary and may not be applicable to all front tooth extraction cases.  There may be cases where nothing can prevent the ridge from collapsing.
