You bit down on something hard and felt a sharp pain for a second, then nothing. No swelling. No obvious damage. So you left it alone.
That is one of the most common ways a cracked tooth gets ignored. And it is also one of the most common reasons patients end up needing much more involved dental work months later.
At DentMind CBD Dental Centre on Kimathi Street, we see cracked teeth regularly. Most patients arrive hoping it is nothing serious. When a crack is caught early, treatment is usually straightforward. But when it has been left too long, options become fewer and the process more complex.
Here is what you need to understand.
Why Cracked Teeth Are So Easy to Miss
Unlike a cavity you can sometimes see, or a broken tooth that is obvious, a crack often gives no visible warning. The pain comes and goes. It appears when you bite down at a certain angle, then disappears completely. Some patients notice cold sensitivity that fades within seconds. Others feel nothing at all.
Research shows that up to 70% of adults have at least one posterior tooth with a visible crack, yet only about 20% of those teeth produce any symptoms.¹ That gap between having a crack and feeling it is precisely why so many people wait too long before seeing a dentist.
What Happens When a Crack Goes Untreated
A crack does not stay the same size. Every time you chew, bite, or clench, the two sides of the crack flex against each other. Over time, that movement pushes the crack deeper.
The concern is not only structural. Crack lines harbour bacteria in biofilms that work their way into the dentinal tubules, triggering inflammation inside the pulp, which is the living nerve tissue at the centre of the tooth.¹ What starts as mild sensitivity can progress to irreversible pulp damage, at which point root canal treatment becomes necessary.
A large clinical study of nearly 2,900 patients with cracked teeth found that biting pain, spontaneous pain, and radiographic evidence of a crack were all strong predictors of needing restorative treatment rather than simple monitoring.² The longer those signs go unaddressed, the further the crack tends to progress.
The Symptoms Worth Taking Seriously
Not every cracked tooth needs urgent treatment, but certain symptoms call for a same-week appointment:
Sharp, brief pain when biting down that disappears quickly. Cold sensitivity that lingers for more than a few seconds. Discomfort that seems to shift around the tooth without a clear source. Intermittent swelling near the gum around a single tooth.
These are the signs the team at DentMind CBD assesses during examination, using bite tests and transillumination where needed. Catching a crack at this stage typically means a composite filling, an onlay, or a crown, depending on how far the crack has progressed.
What Treatment Actually Looks Like
The good news is that a cracked tooth caught early carries a very good outlook. Teeth with a healthy or mildly inflamed pulp that receive prompt treatment with direct or indirect composite restorations have shown pulp survival rates of around 93% over seven years.¹
When a crack has progressed and root canal treatment becomes necessary, survival rates after endodontic treatment remain comparable to non-cracked teeth that receive the same procedure, generally between 84% and 90%.¹ The key factor in both situations is not waiting.
Teeth left without a permanent restoration after a crack is identified face a risk of failure more than 12 times higher than those that receive proper coverage.¹ Doing nothing is rarely a neutral choice.
Do Not Wait for the Pain to Get Worse
A tooth that can be restored today with a filling or a crown may not be restorable in six months. Once a crack extends below the gum line or into the root, treatment options narrow sharply, and both the complexity and cost increase considerably.
