Cracked Tooth Treatment in Johnson City, TN

Medically reviewed by Dr. Riley Sturgill, DMD, MSD. Last reviewed June 2026.

A cracked tooth rarely announces itself. One day a bite of something crunchy sends a sharp jolt through a back tooth, and then it fades. You start chewing on the other side without really deciding to. Days later it happens again, maybe with something cold, maybe out of nowhere. By the time you make it to a dentist's chair, the pain has gone quiet, the X-ray looks clean, and you half wonder if you imagined the whole thing.

You did not imagine it. Cracks in teeth are one of the hardest problems in dentistry to pin down, and plenty of people live with the discomfort for months before anyone puts a name to it. A fracture too thin to show on a standard X-ray can still run deep enough to hurt every time you bite. That gap, between what you feel and what an X-ray can show, is why cracked teeth so often end up needing a specialist.

Sturgill Endodontics is a specialty practice in Johnson City, TN, and finding and treating cracked teeth is part of the daily work here. If a tooth is hurting badly right now, you do not have to wait it out.

What to do if you cracked or broke a tooth

Whether the tooth cracked or a piece broke off entirely, a few things help in the hours before you can be seen. Rinse gently with warm salt water to keep the area clean. If chewing or cold air sets the tooth off, bite down on a piece of clean, damp gauze and favor the other side when you eat. An over-the-counter anti-inflammatory such as ibuprofen, taken as directed on the label, brings down pain and swelling, and a cold compress against your cheek helps with swelling too.

Our office is open Monday through Thursday, 8am to 5pm, and closed Friday through Sunday. If you reach us during the week, call as early in the day as you can so we can find you the soonest opening.

What a cracked tooth actually is

Your tooth has three layers. The hard white outer shell is enamel. Beneath it sits dentin, a softer layer that carries sensation. At the center is the pulp, the living tissue that holds the nerve and blood supply. When a crack opens a path through those layers, chewing flexes the pieces against each other and irritates the nerve underneath. That movement is why the pain so often spikes the moment you bite down, then again the moment you let go.

Not every crack means the same thing. The American Association of Endodontists sorts them into a handful of types, and the type decides almost everything about what comes next. Craze lines are shallow lines in the enamel that nearly everyone picks up with age. They cause no pain and need nothing beyond a cosmetic fix. A fractured cusp, where a piece of the chewing surface breaks off near a filling, usually spares the nerve and can be rebuilt with a filling or a crown.

The trickier case is a true cracked tooth, where the fracture runs from the chewing surface down toward the root without splitting the tooth apart yet. Caught early, that tooth can often be saved. Ignored, the crack tends to spread.

Two types carry a harder outlook. A split tooth has already separated into segments. With a vertical root fracture, the break starts down at the root and creeps up under the gum, often hidden until the surrounding bone gets involved. Sometimes a portion of the tooth can be rescued with surgery. Often the honest answer is that it needs to come out, and we would rather tell you that plainly than charge you to treat a tooth that cannot be saved.

One thing every type shares is that a cracked tooth does not repair itself. Bone knits back together. Tooth structure does not. Once a crack forms, the whole job is to stop it from getting worse and protect what is left.

What causes a cracked tooth?

Teeth rarely crack out of nowhere. Years of grinding or clenching, often during sleep, fatigue a tooth the way bending a paperclip back and forth eventually snaps it. A tooth with a large old filling has less of its own structure left to absorb a hard bite, which leaves it more likely to give way. Everyday habits add up too. Chewing ice is a common culprit, along with biting into hard candy or down on a stray popcorn kernel, or using your teeth to tear open packaging. A direct blow from a fall or a sports injury can crack a tooth on the spot. Age plays a quieter role, since teeth grow more brittle over the years, and a bite that would have been harmless at thirty can split a tooth at sixty.

Symptoms of a cracked tooth

A cracked tooth usually gives itself away through how it feels, not how it looks, which is why people live with it for so long. The signs tend to come and go, so they are easy to wave off until they are not. A few that are worth paying attention to:

Why a cracked tooth is so hard to diagnose

Here is the part that frustrates so many people. Those same symptoms are remarkably easy to miss or misread. The pain travels, so it can feel like it belongs to a different tooth, or to your ear, your sinus, even your jaw joint, which sends plenty of people chasing the wrong problem. A standard X-ray captures the tooth from one flat angle, and a hairline fracture running the wrong direction can disappear on it completely. People get sent home with a clean film and a shrug far more often than they should.

How we find the crack

Finding a crack takes equipment built for the job. Every case here gets a dental operating microscope and a CBCT scan, a three-dimensional X-ray that shows the tooth from every angle instead of a single flat one. Under high magnification, a fracture line that is invisible to the bare eye comes into view. We also use transillumination, shining a focused light through the tooth so a crack interrupts the glow as a dark seam, and a bite test that isolates one cusp at a time to reproduce the exact pain you have been trying to describe. Alongside those, sensibility testing checks how the nerve inside the tooth responds, which tells us whether the pulp is healthy or already in trouble.

The goal of all of it is the same: name the problem precisely before anything touches the tooth. You can see the imaging setup we use on our endodontic technology page.

What treatment looks like

Treatment follows the crack. If the fracture stays in the outer layers and the nerve is still healthy, a crown that caps and binds the tooth may be all it needs. When the crack has reached the pulp and the nerve is inflamed or infected, the tooth usually needs root canal treatment, which clears out the damaged tissue inside, cleans and seals the canals, and removes the source of the pain. A crown then goes over the top to hold everything together and keep the crack from creeping further.

Depending on the case, that final restoration can often be handled as part of your treatment here, rather than sending you to a second office to finish the job. You can read how the procedure itself actually goes on our root canal treatment page.

Can my tooth be saved?

This is the question almost everyone asks first. The honest answer is that it depends on where the crack sits and how far it has traveled, and we will not know for certain until we look closely with the right tools. Fractures caught early, before they reach below the gum, carry the best odds. A crown gives a cracked tooth strong protection, though no honest dentist will promise a crack can never progress. What you will get here is a straight read on your specific tooth and a recommendation you can trust, grounded in what the exam and the imaging actually show.

Comfort while you are in the chair

Dread keeps a lot of people in pain longer than the tooth ever would. If that sounds like you, the room is set up to take the edge off. Bose noise canceling headphones and Netflix run during treatment. The chair itself is a massage chair, with a sherpa or weighted blanket and a memory foam pillow for your neck or knees if you want one. Nitrous oxide is available when it helps, though additional fees may apply for it. None of it speeds up or slows down the actual work on your tooth. It just makes the time in the chair easier to sit through.

What it costs and how insurance works

Sturgill Endodontics is out of network with dental insurance plans. In practical terms, that means we do not file claims for you, but we do prepare the paperwork you need, with the procedure codes your insurer asks for, so you can submit it and be reimbursed under your out-of-network benefits. Many plans cover a portion of cracked tooth and root canal treatment after your deductible, though the exact share varies by plan. Before treatment begins, you will get a clear estimate of the cost, so the number is in front of you ahead of any decision. The fastest way to understand your own coverage is to call and walk through it with our team.

Why patients across the Tri-Cities come here

General dentists throughout the region refer their cracked tooth cases to specialists for a reason. A practice that does nothing but endodontics sees these fractures every day and keeps the equipment on hand to find them. Patients drive in from Kingsport, Bristol, Elizabethton, and across Northeast Tennessee and Southwest Virginia because specialist-only care is not waiting on every corner.

Dr. Colton Fischer is a Board Certified Diplomate of the American Board of Endodontics, the highest credential the field offers, and founder Dr. Riley Sturgill built the practice around saving teeth that other offices were ready to give up on. The office carries a 5.0 star rating across its Google reviews. If you want to understand what actually separates a specialist from a general dentist for a problem like this, our overview of endodontics lays it out.
