Vowel Lady,

What tests are used to evaluate for infection? I have no swelling or redness around my gums. Does this mean anything at all?
A DENTAL CT SCAN WOULD SHOW ABNORMALITIES IN THE BONE INDICATIVE OF INFECTION. INFECTION RESIDING IN THE BONE DOES NOT ALWAYS SHOW AS SWELLING OR REDNESS AT THE GUM LEVEL UNTIL IT IS ADVANCED.

What is the best way to test tooth 30 for infection?
IF TOOTH #3O HAS BEEN ROOT CANALED, IT IS INFECTED. THERE IS NO CURE FOR AN INFECTED TOOTH.

How might a dental professional determine if the graft is infected?
DIAGNOSIS VIA DENTAL CT SCAN... SOMETIMES A PANORAMIC RADIOGRAPH.... SOMETIMES THEY HAVE TO SURGICAL GO IN AND LOOK AT IT.

Tooth #31 has been extracted. Perhaps 30 will be at some time. Can I get a partial bridge without some kind of anchoring tooth?
YES, YOU HAVE SAID THAT #31 IS ALREADY EXTRACTED. A UNILATERAL PARTIAL DENTURE REPLACES TEETH THAT ARE MISSING ON ONE SIDE OF AN ARCH. THIS TYPE OF APPLIANCE USUALLY HAS A METAL BAR THAT COMES ACROSS THE BACK OF THE LOWER FRONT TEETH. YOU WOULD HAVE TO DISCUSS YOUR REPLACEMENT OPTIONS WITH YOUR DENTIST.
