The 5 Types of Tooth Cracks

The type, location, and depth of a crack determine your treatment options and whether the tooth can be saved. Tap each type to understand what it means for you.

Craze Lines Low Risk

Tiny surface cracks in the enamel only. Extremely common in adults, especially on back teeth. They cause no pain, pose no structural risk, and require no treatment beyond monitoring. Often noticed only during a dental exam.

Fractured Cusp Same-Day

A piece of the tooth's chewing surface breaks away, usually around a large filling or weakened enamel. Often causes minimal pain because the pulp (nerve) is rarely involved. A crown typically restores the tooth completely.

Cracked Tooth Same-Day

A crack that starts at the chewing surface and extends down toward -- or into -- the root. This is the classic cracked tooth syndrome. Pain when biting and releasing is the hallmark symptom.

If the crack has not yet reached the pulp, a crown can stop its progression. Once the pulp is involved, a root canal is needed first. Do not delay -- every bite deepens the fracture.

Split Tooth Urgent

The tooth has fully separated into two distinct segments -- the end stage of an untreated cracked tooth. The segments can no longer be united. Whether a portion of the tooth can be saved depends on the location of the fracture. Extraction of at least one root is usually required.

Vertical Root Fracture Urgent

A crack that begins in the root and extends upward toward the crown. Often painless for months until the surrounding bone and gum become infected. Frequently discovered on X-ray or CBCT. The prognosis is poor -- extraction is usually necessary, but a dental implant can replace the tooth predictably.

Symptoms of a Cracked Tooth

Cracked teeth are notoriously difficult to self-diagnose. The symptoms are often intermittent and can mimic other dental problems. You might have a cracked tooth if you notice:

  • Sharp pain when biting down that is immediately relieved when you release pressure
  • Sensitivity to cold, heat, or sweet foods that lingers longer than a few seconds
  • Pain that comes and goes with no consistent pattern -- sometimes absent for days
  • Discomfort localized to one area of the mouth but difficult to pinpoint to a single tooth
  • Swelling or tenderness in the gum around one tooth
  • A visible chip, crack line, or piece of tooth that has broken off

Why Cracks Happen

Teeth crack for a variety of reasons, and it can happen to anyone regardless of how well they care for their teeth. Common causes include:

Biting hard objects

Ice, hard candy, popcorn kernels, unpopped seeds, or using teeth as tools places sudden impact force that enamel was not designed to absorb.

Teeth grinding (bruxism)

Chronic nocturnal grinding produces sustained lateral forces that fracture enamel over time, often starting at the edges of existing fillings.

Large fillings and old restorations

A tooth with a large amalgam or composite filling has less structural integrity. The remaining walls of enamel are thinner and more susceptible to fracture.

Trauma

A blow to the face, a fall, or a sports impact can crack teeth even without knocking them out. Cracks from trauma are not always immediately painful.

Temperature extremes

Eating very hot food followed immediately by cold -- or vice versa -- causes rapid expansion and contraction that can initiate micro-fractures over time.

What Happens If You Leave It Untreated

Cracks do not close or heal on their own. Every time you chew, biting forces push on both sides of the fracture line. Here is how the progression typically unfolds:

1
Crack deepens into the dentin

Sensitivity and pain intensify. The dentin tubules conduct temperature and pressure changes directly to the nerve, making eating increasingly uncomfortable.

2
Crack reaches the pulp

Bacteria now have a pathway to the nerve and blood supply. The pulp becomes inflamed (pulpitis) and then infected. Constant, throbbing pain sets in. A root canal is now required to save the tooth.

3
Abscess forms

Infection spreads to the root tip and into the surrounding bone, forming a periapical abscess. Swelling, pus, and fever may develop. The bone around the root begins to dissolve.

4
Tooth splits or must be extracted

Once the crack completes and the tooth separates, or infection destroys enough bone support, extraction becomes unavoidable. At this point, an implant or bridge is required to restore the space.

The earlier a crack is treated, the simpler and less expensive the treatment. Many cracked teeth caught before they reach the pulp need only a crown.

How We Diagnose a Cracked Tooth

Cracks are often invisible on standard X-rays. Our diagnostic process uses multiple methods to locate and assess the fracture before recommending any treatment.

Visual Exam with Magnification

Dental loupes and focused lighting reveal hairline fractures that are invisible to the naked eye. We examine all surfaces of every suspect tooth.

Transillumination

A high-intensity fiber optic light is shone through the tooth. Cracks scatter light differently than intact enamel, revealing fracture lines that would otherwise be invisible.

Bite Test (Tooth Sleuth)

We have you bite on a small plastic instrument one cusp at a time. Sharp pain when biting on a specific cusp and releasing pressure localizes the crack to a precise location.

Digital X-Rays

Periapical X-rays reveal infection, bone loss, and widening of the periodontal ligament space -- indicators that a crack has progressed or an abscess has formed at the root tip.

CBCT Cone-Beam CT

For complex or suspected vertical root fractures, our in-house CBCT scanner produces a 3D image of the tooth and surrounding bone. This is the most precise tool available for assessing fracture depth and extent.

Periodontal Probing

We probe around the entire perimeter of the gumline. A narrow, isolated deep pocket -- a "draining sinus" -- often indicates a vertical root fracture even before it is visible on X-ray.

Treatment Options by Severity

Treatment is matched to the type and depth of the crack. Our goal is always to use the most conservative approach that reliably solves the problem.

CRAZE LINES

No Treatment Required

Craze lines confined to enamel require only monitoring. We note their presence and recheck at your regular appointments. No intervention is needed unless they deepen or cause symptoms.

MINOR CHIPS & SURFACE CRACKS

Dental Bonding

For small chips or cosmetic cracks limited to enamel, tooth-colored composite resin is bonded and shaped directly to the tooth in a single visit. No anesthesia is often needed. This is the fastest and most conservative repair.

FRACTURED CUSP / CRACKED TOOTH (INTACT PULP)

Dental Crown

A crown is the standard treatment for a cracked tooth whose pulp is still healthy. The crown encases the entire tooth, preventing the crack from spreading further under biting forces. We fabricate same-day CEREC crowns on-site -- no temporary crown, no second appointment. The crown must be placed promptly; delay risks the crack reaching the pulp.

CRACK INTO PULP / PULPITIS

Root Canal + Crown

When the crack has reached the pulp, root canal therapy removes the infected or inflamed nerve tissue and seals the canals. The tooth is then restored with a crown. Modern root canals with proper anesthesia are straightforward -- most patients are surprised how comfortable the procedure is. The tooth is preserved and functional.

SPLIT TOOTH / VERTICAL ROOT FRACTURE

Extraction + Implant Replacement

When a tooth cannot be saved, prompt extraction prevents ongoing infection and bone loss. Dr. Dawson places the dental implant in the same surgical site once healing is adequate. A dental implant is the most durable, natural-feeling tooth replacement available and does not require altering adjacent teeth.

Can My Cracked Tooth Be Saved?

The most important factor is timing. Most cracked teeth are completely saveable when treated before the crack reaches the pulp. Once infection has set in, the tooth can still usually be saved with a root canal and crown -- but cost and treatment time increase.

The crack types that cannot generally be saved are split teeth (where the tooth has separated into two pieces) and vertical root fractures that have compromised significant bone support. In those cases, we focus on the cleanest possible extraction and the best replacement option.

If you are unsure whether your tooth is saveable -- call us. A 30-minute diagnostic appointment gives you a clear answer and a specific treatment plan. You do not have to guess.

Cost Factors for Cracked Tooth Treatment
  • Bonding: $150 -- $400 per tooth (often partially covered by insurance)
  • Crown: $1,200 -- $1,800 per tooth (same-day CEREC available, insurance often covers a portion)
  • Root canal: $900 -- $1,500 depending on tooth location (molars are more complex)
  • Extraction: $175 -- $350 for a straightforward extraction
  • Dental implant: $3,500 -- $5,500 all-in including crown (CareCredit, Cherry, Sunbit financing available)

Not a diagnosis. Fracture type and urgency are confirmed by clinical exam, transillumination, and bite tests. If you have severe pain, facial swelling, or a visible piece of tooth has broken off, call (480) 530-3663 or seek emergency care now.

Reference

A field guide to tooth fractures

Tooth cracks follow five distinct patterns from surface-only craze lines to root fractures. The signature symptoms on the left are what your dentist tests for; the description and treatment are on the right. Only an in-person exam with bite tests and transillumination can confirm a fracture type.

Signature symptoms

  • No pain or very mild sensitivity to cold
  • Visible fine lines in the enamel surface
  • No pain on biting

Craze Lines

Hairline cracks limited to the outer enamel layer. No structural threat to the tooth and no treatment required — but a dentist should confirm there is no deeper involvement.

Signature symptoms

  • A piece of the tooth broke off or feels sharp
  • Sharp pain when biting in one spot
  • Brief cold sensitivity at the site

Fractured Cusp

A cusp — one of the pointed corners of a back tooth — has broken away, usually around an existing filling. The nerve is rarely involved. A crown restores the tooth.

Treated with Crown or onlay →

Signature symptoms

  • Sharp pain when biting down
  • Sharp pain when releasing the bite
  • Intermittent pain over weeks or months
  • Cold or sweet sensitivity that lingers

Cracked Tooth (Cracked Tooth Syndrome)

An incomplete crack running from the crown downward — it has not yet split the tooth into two pieces. The hallmark is pain on releasing the bite as the crack flexes open. Without treatment, it progresses to a split tooth or root fracture.

Treated with Crown; root canal if the nerve is involved →

Signature symptoms

  • A crack that visibly separates two parts of the tooth
  • Severe pain or complete relief once the tooth splits
  • Tooth feels loose or pieces feel separate

Split Tooth

A cracked tooth that has propagated all the way through, splitting the tooth into distinct segments. The tooth is usually not restorable as a whole. Extraction is nearly always required, and replacement planning begins immediately.

Treated with Extraction and tooth replacement planning →

Signature symptoms

  • Dull or absent pain despite signs of infection
  • Pimple-like bump on the gum next to the tooth
  • Previous root canal on the tooth
  • Recurring abscess or swelling around one tooth

Vertical Root Fracture

A crack that begins in the root and extends upward toward the crown, often after root canal treatment. It is frequently silent until an abscess forms around the root. Extraction is almost always required.

Treated with Extraction in most cases →

Frequently Asked Questions

No. Tooth enamel cannot regenerate or repair itself. A crack will not close, seal, or shrink over time. It will remain the same or deepen under normal biting forces. The sooner you have it evaluated and treated, the simpler and less expensive the solution.

Yes. Many cracked teeth are not very painful in the early stages -- especially craze lines and fractured cusps. But absence of pain does not mean the crack is not progressing. A cracked tooth treated before symptoms worsen nearly always requires simpler treatment. Waiting until it hurts significantly often means the crack has reached the pulp.

Yes, for the vast majority of cases. A crown holds the tooth together and distributes biting forces across the entire crown, preventing the crack from deepening. This is why prompt crown placement after a cracked tooth diagnosis is important -- the longer you wait, the more likely the crack progresses to the pulp during that interval.

Bonding can be done in a single 30 -- 60 minute visit. A crown with our CEREC system is completed in a single 90 -- 120 minute appointment -- no temporary and no return visit for a crown cementation. If a root canal is also needed, that typically adds 60 -- 90 minutes and can often be combined with the crown prep in the same visit.

The crack will deepen. A tooth that needed only a crown can become a tooth that needs a root canal and crown. A tooth that needed a root canal and crown can split in half or develop an abscess. In the worst case, the infection spreads to surrounding bone and the tooth is lost entirely -- leaving you needing an implant or bridge at considerably greater expense.

It depends on depth. A visible hairline in enamel may be a craze line -- cosmetic only, not a concern. A visible crack that extends toward the gumline or appears to separate tooth structure warrants same-day evaluation. If you can see daylight through it, or if it involves a tooth with a large filling, call us today.

Most dental insurance plans cover crowns and root canals at 50 % after your deductible, subject to annual maximums. Some plans cover bonding. We will verify your benefits before treatment and give you a clear breakdown of estimated out-of-pocket costs. Financing through CareCredit, Cherry, and Sunbit is available with no-interest options.

Yes -- and you should be significantly more comfortable eating once the crown is placed. Immediately after the anesthetic wears off, the area may be tender for a day or two, particularly if a root canal was also performed. By the end of the first week, most patients report no discomfort whatsoever. We recommend avoiding extremely hard foods (ice, hard candy) on any crown permanently.
