it is essential to have strong adjacent supporting tooth for the placement of fixed partial denture.
ie,the teeth should not be compromised by dental carries/periodonitis/gingival recession
for this,the broken tooth has to be removed by your dentist
such extraction is not a great task for agood dentist.
if you are not medically compromised with diabetes
,etc.the socket will heal within 2 weeks after extraction.
after this the supporting teeth has to be done crown cutting and impression should be taken.on this basis,you can get new fixed partial denture.
if the missing tooth is not replaced,it can effect occlusion,mastication,malalignment of teeth etc.
