Can a Cracked or Broken Tooth Get a Root Canal?

Imagine this, you’re enjoying a casual lunch with colleagues, biting into a sandwich, when suddenly crack! A sharp pain shoots through your tooth. At first, you wonder if it’s just something stuck, but later that evening, the pain returns whenever you chew. The next day, you notice a fine line running across your tooth in the mirror.

Situations like this are far more common than you might think. Cracked teeth are one of the leading reasons patients end up needing root canal treatment in Vancouver, BC . And here’s the tricky part: not all cracks are the same. Some can be treated and saved with a root canal and crown, while others may be too deep and require extraction.

In the article, we’ll explore the different types of cracks, the symptoms that signal trouble, how dentists diagnose them, what happens if a tooth with a root canal cracks, and when to seek care from a Vancouver dentist.

Types of Tooth Cracks (and Whether a Root Canal Helps)

When it comes to cracked teeth, location, depth, and direction of the fracture are the three most important factors that determine whether the tooth can be saved with a root canal or whether extraction becomes necessary. Understanding these categories helps patients set realistic expectations and take action before the crack spreads further.

Craze Lines: Cosmetic Only, No Root Canal Needed

Craze lines are the most superficial type of cracks. They are tiny, hairline fractures limited to the enamel, the outer protective shell of the tooth. Almost everyone develops them over time due to normal wear and tear, habits like teeth grinding, or frequent temperature changes from hot and cold foods.

Symptoms: Typically, painless, though some patients may notice staining along the lines.
Treatment: No root canal is required. If the appearance bothers you, cosmetic options such as enamel polishing or whitening can help.

Think of craze lines as the “laugh lines” of teeth; they’re a sign of age and use, but not a danger to the health of the tooth.

Fractured Cusp: Root Canal + Crown if Deep

A fractured cusp occurs when a portion of the tooth’s chewing surface breaks away, often around a large filling or weakened tooth structure.

Symptoms: You may feel a sudden sharp edge with your tongue, experience mild discomfort when chewing, or notice food trapping in the fractured area.
Treatment: If the fracture is shallow and does not reach the pulp, the dentist can restore it with a crown alone. But if the fracture extends deep enough to irritate the pulp, a root canal will be necessary before crowning.

In short, the deeper the fracture goes, the more likely the pulp is involved, and that’s when a root canal becomes essential.

Cracked Tooth (Extending Into Dentin): Root Canal + Crown if Pulp Is Involved

This is more serious than a fractured cusp. The crack begins on the chewing surface and extends vertically toward the root, passing into the dentin layer.

Symptoms: Patients often report sharp pain when biting down, especially when releasing pressure. Sensitivity to temperature (hot or cold) is also common. Without treatment, the pulp may become inflamed or infected.
Treatment: If the pulp is affected, the standard solution is a root canal treatment to remove infection, followed by a full crown to reinforce the tooth and prevent the crack from spreading further. Prognosis is usually good if caught early.

This type of crack is often what people imagine when they say “my tooth cracked.” It’s treatable, but timing is everything.

Split Tooth / Vertical Root Fracture: Extraction Usually Required

The most severe category is when the crack travels deep into the root or splits the tooth into separate segments. Unfortunately, once the root itself is fractured, the tooth cannot usually be saved.

Symptoms: Pain when chewing, mobility of the tooth, swelling of the gums, or even a visible separation of the tooth segments.
Treatment: Extraction is almost always necessary. Depending on the case, your dentist may recommend replacing the tooth with a dental implant, bridge, or partial denture to restore function.

The goal is to prevent cracks from ever reaching this stage, which is why early diagnosis and protective crowns are so critical after a root canal.

Do You Need a Crown After a Root Canal?

One of the most common questions patients ask is, do you need a crown after a root canal? In most cases, yes. After root canal treatment, teeth are more brittle. Without a crown, there’s a higher chance of a fracture or chip. A crown works like armor, restoring both function and appearance. Skipping it is a common reason patient later face failed root canal symptoms.

Symptoms That Suggest the Crack Needs a Root Canal

How do you know when a crack is more than cosmetic? Look for:

Lingering sensitivity to hot or cold
Sharp pain when biting or releasing
Spontaneous toothaches that come and go
Swelling or gum tenderness near the tooth

If these sound familiar, it’s time for an exam at a general dentistry clinic in Vancouver.

How Dentists Diagnose a Cracked Tooth

Cracks can be sneaky. X-rays alone often miss them. That’s why your dentist may use:

Bite test: pain when pressure is released is a tell-tale sign
Trans illumination: shining light to highlight crack lines
CBCT scans: advanced 3D imaging of tooth roots
Periodontal probing: measuring gum depth for signs of hidden cracks

What If the Tooth Cracks After a Root Canal?

This is a worry for many patients. Here are common situations:

Root canal tooth chipped: often restorable with a crown or filling.
Root canal tooth chipped off near the gum line: may still be saved if enough structure remains above the bone.
Root canal cracked tooth syndrome: ongoing pain may point to a vertical root fracture, which often can’t be saved.

The good news: not every cracked root canal tooth is doomed. Quick diagnosis gives the best chance of saving it.

Treatment Timelines & Prognosis

When it comes to cracked teeth, timing is everything. The earlier the problem is diagnosed and treated, the higher the chances of saving the tooth with simple restorative care. Delays allow the crack to spread deeper, often leading to pulp involvement, infection, or even fractures that require extraction.

Early cracks (before pulp damage): Excellent prognosis with a crown.
Cracks into dentin but not root: Good prognosis if treated quickly with root canal + crown.
Vertical root fractures: Poor prognosis; extraction and replacement (implant or bridge) needed.

What Happens During a Root Canal for a Cracked Tooth?

If you’ve never had one, here’s what happens step by step:

Numbing: a local anesthetic makes the process pain-free.
Cleaning: removing the infected pulp.
Sealing: disinfected canals filled with biocompatible material.
Restoring: placing a crown to protect against further damage.

Think of it as repairing the inside (root canal) and shielding the outside (crown).

Can an Endodontist Do a Root Canal on a Cracked Tooth?

Yes, and in complex cases, it’s recommended. Endodontists are specialists in root canal therapy. If you’ve been told your cracked tooth needs extraction, a second opinion may reveal it can still be saved.
