Can an exposed nerve in one lower right molar tooth cause deep pain in other molars upper and lower, right and left?
Ans. No - The tooth with an exposed nerve cannot cause deep pain in other teeth.
Is it possible for an exposed nerve under a cap to cause dull aching pain in its own location and these others - but not react to being tapped on by a dentists metal hammer?
Ans No - In case of a pulp exposure, the tooth has positive tender on percussion.
The reason for dull aching pain many times on a crowned tooth, in absence of any nerve damage, could be due to pocket formation which is a pathological deepening of gingival sulcus. It is a periodontal disease ( disease of supporting structure of the tooth ).However, an accurate diagnosis could be made by radiographical examination.
For the time being, you could take warm saline rinses few times in a day.Keep optimum oral hygiene. Floss the concerned area after every meal.You could apply oral metronidazole gel ( in combination with chlorhexidine - 0.12% ) thrice daily for 3 days.
Note - The metronidazole gel has to be applied topically on the gums.
