One of the most alarming changes a patient can notice is when a tooth suddenly becomes darker than the surrounding teeth. A dark tooth may appear yellow-brown, gray, blue-gray, or even black in severe situations. Many patients in Fresno, California, initially assume the discoloration is simply a stain caused by coffee, tea, wine, tobacco, or aging. However, when only one tooth becomes noticeably darker than the others, it often signals an underlying dental problem that requires professional evaluation.

One of the most alarming dental emergencies a patient can experience is waking up with significant facial swelling accompanied by severe tooth pain. Many patients in Irvine, California, contact a dentist only after noticing that one side of their face has become noticeably enlarged, tender, and painful. In many cases, the underlying cause is an infected tooth that requires immediate root canal treatment.

As a dentist who has treated thousands of root canal patients over the years, one of the most concerning phone calls I receive is from a patient who develops a fever after a root canal procedure.

Many patients in San Diego, California ask:

"Is a fever normal after a root canal?"

The short answer is:

A mild increase in body temperature can occasionally occur after dental treatment, but a true fever is not considered normal and should never be ignored.
