hi...u didnt mention on which side u got your root canal
done? whether the same side u had tingling of tongue? pz check the root canal filling any small canals left unfilled? And in some cases vitamin deficiency
causes tingling sensation
and feeling of heviness in tongue. pz take vitamin C
tabs available as examlpe limcee
for 10 days will solve yr problem. In some cases after administration of local anesthesia
causes this problem. In most of the cases vit C will give the best result.
take care ,
