Exposed Tooth Nerve: Why It Hurts and How to Get Relief
An exposed tooth nerve causes sharp, sudden pain. Learn the causes, how to ease it, and why you need prompt care from our Palm Beach Gardens dentists.
Exposed Tooth Nerve: Why It Hurts So Much and What to Do
What Does an Exposed Nerve Feel Like?
An exposed tooth nerve causes some of the sharpest, most sudden pain in all of dentistry, because the sensitive nerve inside your tooth is no longer shielded by its enamel and dentin. When decay, a crack, a lost filling, or an injury reaches the inner pulp, hot drinks, cold air, and sweet foods can each trigger a jolt of pain that lingers long after the trigger is gone. An exposed nerve will not heal on its own, and the pain tends to escalate, so prompt emergency dental care is the surest way to stop the discomfort and save the tooth.
What Causes a Tooth Nerve to Become Exposed?
Decay, Cracks, Lost Fillings, and Worn Enamel
Knowing the cause helps you understand how urgent the problem is. A nerve usually becomes exposed in one of these ways:
Deep decay that eats through the enamel and dentin until it reaches the pulp.
A broken or cracked tooth, which can split far enough to uncover the nerve. Our guide on a broken tooth walks through the first steps.
A lost filling or crown that leaves the inner tooth open, covered in our lost filling or crown guide.
Worn enamel or gum recession from heavy grinding that exposes sensitive root surfaces.
How to Relieve Exposed Nerve Pain and Treat It
At-Home Comfort and Lasting Dental Treatment
While you wait to be seen, you can take the edge off the pain by rinsing with warm salt water, taking over-the-counter pain relievers as directed, and avoiding very hot, cold, or sweet foods. If there is a visible hole, temporary dental filling material or a dab of dental wax from the pharmacy can shield the area, and sleeping with your head slightly elevated can ease throbbing, as our fast toothache relief guide explains. These steps only buy time, though. The lasting fix depends on the cause: our dentists may place a new filling or crown to re-cover the nerve, or recommend root canal therapy if the pulp is already infected, which reliably removes the pain and preserves your natural tooth.
