Broken Tooth Thornhill: What Type of Fracture You Have Determines What Happens Next
Same-day broken tooth assessment and treatment in Thornhill — call (289) 597-7191.
A broken tooth is rarely a single, clear-cut problem. The term covers everything from a hairline crack that causes occasional discomfort to a complete split that leaves a root fragment behind. What you should do, how urgently you need to act, and whether the tooth can be saved all depend on the type and extent of the fracture. At MiNa Family Dentistry, Dr. Neda Kadivar assesses broken teeth with on-site digital X-rays and provides treatment the same day whenever structurally and clinically possible.
Five Types of Tooth Fractures
Understanding fracture types helps set realistic expectations before you arrive. Dr. Kadivar will confirm the classification during your examination.
Craze Lines
Craze lines are superficial cracks in the outer enamel only. They are extremely common, often caused by temperature fluctuations, minor trauma, or years of grinding. They do not penetrate to the dentin or pulp, cause no pain, and require no treatment other than monitoring.
Fractured Cusp
A cusp is one of the raised points on a back tooth. When a cusp breaks off from biting hard food or from a weakened tooth, the fracture is usually not painful because it rarely reaches the nerve. Treatment is typically a dental crown to restore the tooth's structure and prevent further fracture.
Cracked Tooth
This fracture extends from the chewing surface downward toward the root but has not separated into two pieces. The classic symptom is sharp pain when biting and an instant release of that pain when pressure is removed. Cold sensitivity that lingers is another indicator. A cracked tooth that has not yet reached the nerve can often be saved with a crown. If the crack has extended into the pulp, root canal therapy followed by a crown is required. A crack that has reached below the gumline may not be saveable.
Split Tooth
A split tooth is the end stage of an untreated cracked tooth — the tooth has separated into two distinct segments. In most cases it cannot be saved intact. Extraction followed by tooth replacement is the most common outcome, though in multi-rooted teeth one root may sometimes be preserved through a procedure called hemisection.
Vertical Root Fracture
A vertical root fracture begins at the root and propagates upward. It is frequently seen in teeth that have previously had root canal therapy without a crown to protect the brittle root-treated tooth. Symptoms can be minimal for months, often presenting as a persistent low-grade infection or gum abscess alongside the root. Vertical root fractures almost always require extraction.
Which Broken Teeth Can Be Saved?
The sooner a cracked tooth is treated, the better the odds of saving it. A crack that has not yet reached the nerve can be stopped with a crown. Delaying treatment allows the crack to propagate deeper, at which point root canal therapy may become necessary or the tooth may become unsaveable.
| Fracture Type | Can the Tooth Be Saved? | Likely Treatment |
|---|---|---|
| Craze lines | Yes — no treatment needed | Monitoring only |
| Fractured cusp | Usually yes | Crown, possibly bonding |
| Cracked tooth — nerve not involved | Yes | Crown |
| Cracked tooth — nerve involved | Often yes | Root canal plus crown |
| Cracked tooth — below gumline | Unlikely | Extraction |
| Split tooth | Rarely | Extraction plus implant or bridge |
| Vertical root fracture | No | Extraction plus implant or bridge |
Immediate First Aid for a Broken Tooth
What you do in the hours before your appointment can affect both your comfort and the treatment options available.
- Rinse gently with warm water — not cold, which can intensify sensitivity in exposed dentin
- Save any tooth fragments, rinse gently, and bring them to your appointment stored in milk or saline
- Stop any bleeding by applying gentle pressure with clean gauze for 10 to 15 minutes
- Cover sharp edges with dental wax or sugarless chewing gum to protect your tongue and cheek
- Avoid biting on the affected side and avoid hard, crunchy, sticky, or temperature-extreme foods
- Take ibuprofen as directed — it reduces both pain and inflammation
What Happens at a Broken Tooth Appointment
When you arrive at MiNa Family Dentistry, Dr. Kadivar examines the tooth using magnification where needed, probing for crack depth and assessing the gum tissue around the tooth. Digital periapical X-rays are taken immediately to reveal root involvement, bone level, and whether infection is present.
Transillumination — a fibre-optic light shone through the tooth — can illuminate crack lines that are otherwise invisible. A bite test, where you bite on a small instrument in different positions, helps identify crack location and depth. For fractured cusps and chips, bonding or crown preparation can begin the same visit. For teeth requiring root canal therapy, that process is initiated the same day in most cases.
Treatment Options
Dental Bonding
For minor chips involving only enamel where the nerve is not exposed, composite resin bonding can restore the tooth's appearance in a single visit. Bonding is less durable than a crown but requires minimal tooth preparation and is a cost-effective solution for cosmetic chips.
Dental Crown
A broken cusp or cracked tooth that has compromised tooth structure requires a crown to hold the tooth together and distribute bite forces evenly. Crown preparation and placement are handled in-house at MiNa Family Dentistry.
Root Canal Therapy Plus Crown
When the fracture has exposed the pulp, root canal therapy removes the infected or inflamed tissue, disinfects the canals, and seals the tooth. A crown is then placed over the root-canal-treated tooth to restore full function.
Extraction and Implant or Bridge
When a tooth cannot be saved, extraction followed by a dental implant is the closest replacement to a natural tooth in terms of function and bone preservation. Dr. Adibrad, our on-site dental surgeon with an MSc in periodontics, performs surgical extractions and implant placement at MiNa Family Dentistry without a referral. A fixed dental bridge is an alternative when an implant is not indicated.
Recovery After Treatment
- Bonding: no recovery required — avoid biting hard objects directly with the bonded area
- Crown: mild temperature sensitivity for a few days after preparation, settling once the permanent crown is seated
- Root canal plus crown: soreness around the tooth for two to four days, managed with over-the-counter ibuprofen — most patients return to normal function within a week
- Extraction: soft diet for 24 to 48 hours, no smoking, no straws, and gentle rinsing after the first 24 hours
What Does Treatment Cost?
Bonding for a minor chip ranges from approximately $150 to $350 per tooth. A dental crown is typically $1,200 to $1,800. Root canal therapy on a molar is $900 to $1,400, with the crown additional. Extraction ranges from $200 to $400 for a simple procedure. Most dental insurance plans cover a portion of these treatments. MiNa Family Dentistry submits directly to major insurers and will review your coverage before treatment begins.
