Causes of Tooth Sensitivity After a Filling
Similar to crowns, fillings are another form of dental procedures that is associated with tooth sensitivity to hot and cold. There are a few reasons for this, such as:
– The filling may become loose over time because of recessed gums, wear, or tooth grinding
– The cavity is not completely removed and filled
– The crown or filling is too deep
If tooth sensitivity becomes worse or persists after fillings, your dentist may suggest a root canal. [7]
