Treatment by fracture type — from same-day bonding to extraction with implant replacement
Tooth fractures are not all the same. The treatment for a small chip is dramatically different from the treatment for a vertical root fracture. Knowing what kind of break you have is the first step toward knowing your options. As an emergency dentist serving St. Charles, IL, Geneva, Batavia, and the Fox Valley, Dr. Aqil Valika at Bliss Dental Center sees the full range of broken teeth weekly. This guide explains the five fracture classifications, treatment by type, and which fractures usually mean extraction.
The Five Fracture Classifications
Dentists categorize tooth fractures into five types, in order of severity:
1. Craze lines: superficial cracks in enamel only. Look like fine vertical lines on the front of teeth. Cosmetic concern, not structural. Treatment: usually nothing required; cosmetic bonding if visible enough to bother you.
2. Fractured cusp: a piece of the chewing surface broken off, usually around an old filling that left the tooth weakened. Treatment: filling for small fractures, crown for larger ones.
3. Cracked tooth: a vertical crack extends from the chewing surface toward the root. The tooth is still in one piece. Pain on biting is the classic symptom. Treatment: crown to hold the tooth together; root canal if the crack reaches the pulp.
4. Split tooth: the crack has progressed and the tooth has broken into two distinct pieces. Treatment: usually extraction. Sometimes one half can be saved if the fracture line is favorable, but this is uncommon.
5. Vertical root fracture: a crack that starts in the root and extends upward. Often asymptomatic until infection sets in. Treatment: extraction in nearly all cases.
The Clinical Insight: Why Vertical Root Fractures Mean Extraction
This is the part most patients do not know but should. A vertical root fracture occurs in the root of the tooth — below the gumline, sometimes deep in the bone. Crowns cannot fix it because crowns sit on the visible part of the tooth. Even root canal cannot fix it because the canal seal does not address the structural break in the root itself.
Once a vertical root fracture is diagnosed, the tooth is unsavable. The fracture allows bacteria to seed into the bone surrounding the root, and continued chewing forces deepen the fracture. Extraction is the only path. The good news: replacement options (dental implant or bridge) restore full function — see our implant vs bridge blog post.
Vertical root fractures are most common in: teeth that have had root canals (the canal procedure removes some structural support), teeth with large old fillings, and teeth in patients who grind heavily.
Diagnosis — How We Tell Which Fracture You Have
Cracks are notoriously difficult to diagnose. Even on x-rays, hairline cracks often do not show until they have separated. Diagnostic tools we use at Bliss Dental:
- Visual exam with magnification — finds visible cracks
- Methylene blue dye disclosing — reveals cracks invisible to the naked eye
- Bite test — biting on a small instrument reveals which cusp moves under pressure (the cracked side)
- Cold sensitivity testing — tells us whether the pulp is involved
- Periapical x-rays — show changes in surrounding bone that suggest fracture, even if invisible
- CBCT 3D imaging — for cases where 2D x-rays are inconclusive; can detect vertical root fractures invisible on 2D
If you have biting pain that comes and goes, is hard to localize to a specific tooth, and gets worse with cold drinks, the diagnosis is almost certainly “cracked tooth syndrome.” See our cracked tooth page.
Treatment by Fracture Type
Craze lines: nothing required, optional cosmetic bonding ($300-$500 per tooth) for visible cases. See our dental bonding page.
Fractured cusp: large composite filling ($150-$400) for small fractures, full crown ($1,000-$2,500) when too much tooth is lost to support a filling. See our porcelain dental crowns.
Cracked tooth: typically a crown to hold the tooth together. If the crack reaches the pulp (you have temperature sensitivity that lingers, or constant throbbing pain), root canal is needed before the crown — total $2,000-$4,000.
Split tooth: usually extraction. Replacement with implant or bridge.
Vertical root fracture: extraction. Replacement with implant or bridge.
What to Do Immediately After Breaking a Tooth
- Save the broken piece if you can find it. Put it in milk if it is a meaningful piece. Sometimes we can bond it back.
- Rinse with warm water to clear debris.
- Apply pressure with gauze if there is bleeding.
- Cold compress externally if there is swelling.
- Take ibuprofen + acetaminophen as directed for pain.
- Avoid chewing on the affected side — additional force deepens fractures.
- Avoid temperature extremes — exposed dentin is very sensitive to hot/cold.
- Call (630) 549-7916 for a same-day appointment.
