INTRODUCTION
Understanding Cracked Tooth Syndrome
The term cracked tooth syndrome (CTS) refers to an incomplete fracture of a posterior tooth that intrudes the dentine and occasionally extends into the pulp. This condition is more common in patients aged between 30 and 50 years. Cracked tooth syndrome generally occurs in mandibular second molars, mandibular first molars, and maxillary premolars. It is a common dental problem. Unlike teeth with obvious fractures, teeth with cracked tooth syndrome usually have fractures that are difficult to see on X-rays or with the naked eye. Sometimes the fracture is below the gum line, making it even more difficult to examine or treat.

Sometimes the fracture is below the gum line, making it even more difficult to examine or treat.
The Diagnostic Procedure Involves
History and Visual Examination
1
The diagnostic procedure includes assessment of your previous dental history and a visual examination to look for signs of cracking on the tooth surface.
Exploratory Excavation and Percussion
2
Exploratory excavation and percussion tests help identify which tooth is affected. The dentist may tap on teeth to identify the source of pain.
Bite Tests
3
Bite tests using special instruments can isolate which cusp is cracked. Sometimes a crack affects one or more cusps of a tooth. In this case, the tooth may be fixed with dental crowns. About 20% of teeth with cracked tooth syndrome need root canal treatment.
PREVENTION
Preventions for Cracked Tooth Syndrome
You can protect your teeth's functionality and avoid cracked tooth syndrome by following various preventive care measures: Avoid chewing hard food items. Practice good teeth and gum care. Wear a mouthguard fabricated by your dentist if you play sports or have teeth-grinding habits. Visit your dentist regularly. Visit your dentist regularly. People with one cracked tooth are likely to have cracks in the adjacent teeth as well, either at the same time or in the future. An occlusal spint or night guard can prevent you from grinding or clenching your teeth, reducing the chances of cracking another tooth. At Balsam Dental in The Beaches, we can custom-fit an occlusal splint for you.

SYMPTOMS
Common Symptoms of Cracked Tooth Syndrome
The first symptom of a cracked tooth is intermittent or persistent pain in the affected tooth when you bite or chew. Sometimes people feel pain sensations only when they eat certain foods or bite in a specific way. Moreover, it can get worse with the consumption of sugary foods as the sugar leaks into the tooth crack, causing severe pain. Generally, in cracked tooth syndrome, people do not feel consistent aches, but their teeth become more sensitive to extreme temperatures.
Common signs of CTS
• Intermittent or persistent pain when biting or chewing
• Increased sensitivity to extreme temperatures
• Pain when eating sweet foods
• Swelling around the tooth
• Infection or inflammation in the affected tooth
• Dysfunctional teeth
Many people with cracked tooth syndrome have symptoms for months, but it's difficult to diagnose because the symptoms are not consistent. If your teeth show any of these symptoms, you might have CTS and need immediate treatment. At Balsam Dental in The Beaches, we intend to correct every kind of oral irregularity and effectively restore oral health.
BENEFITS
Diagnosis, treatment, and timeline: what to know.
Why Do Cracked Teeth Hurt?
Our teeth generally consist of three layers: the outer layer (enamel), the middle layer (dentin), and the innermost layer (the pulp). When the outer layer of teeth gets cracked, it makes the pulp irritated or damaged, resulting in pain sensations while chewing food. Cracks in teeth also make them sensitive to extreme temperature conditions. Moreover, extensive cracks in teeth lead to pulp tissue infection, which also damages adjacent teeth's functionality.
What Are the Common Treatments for Cracked Tooth Syndrome?
Minor cracks in teeth are generally treated with dental crowns or fillings. However, these approaches are unable to cure deep cracked teeth. In such situations, root canal therapy becomes necessary. If a crack exceeds the gumline or the pulp, the tooth no longer remains treatable and dentists usually extract those teeth. After tooth extraction, you can replace it with various dental alternatives, such as dental implants or a bridge.
How Long Can You Live with a Cracked Tooth?
If a crack is minor, it does not show extreme symptoms, and the person would normally feel minimal pain while chewing hard food items. However, if a cracked tooth remains untreated for prolonged periods, it can severely affect the form and function of the tooth. That's why a cracked tooth should not be ignored for more than two weeks, as immediate treatment can save the affected tooth's functionality and prevent severe oral issues.
Why Does Cracked Tooth Syndrome Occur?
Cracked tooth syndrome usually occurs in molars or lower molars, which severely affects your chewing forces. People who grind or clench their teeth are more susceptible to having cracked tooth syndrome because of the consistent strain and force on teeth. Teeth with large fillings or teeth that have undergone root canal treatment are weaker than other teeth and are usually more likely to crack.
Can a cracked tooth heal on its own?
Unfortunately, no. Unlike bone, tooth enamel can't regenerate. A crack won't heal itself, and left untreated it usually gets worse over time — spreading deeper into the tooth or leading to infection. The good news is that most cracked teeth can be saved if treated early with a crown or, if needed, a root canal followed by a crown.
How can I prevent cracking another tooth?
If you cracked one tooth, you're at higher risk of cracking others — especially if grinding or clenching played a role. A custom night guard is one of the best preventive measures we can offer. Also avoid chewing hard objects (ice, pens, popcorn kernels), get large old fillings replaced with crowns when they weaken the tooth, and come in for check-ups so we can catch stress fractures early.
Why is my cracked tooth so hard to diagnose?
Cracks are often microscopic and don't show up on standard X-rays. Symptoms can also be intermittent — pain that comes only when biting a certain way, or sensitivity to specific temperatures. We use special diagnostic tools (like bite tests with a tooth sleuth) to isolate which tooth is cracked and which specific cusp is affected. It sometimes takes patience to pinpoint.
Should I get my other teeth checked if one is cracked?
Yes — this is a good idea. If one tooth cracked, others may be under similar stress, especially if you grind or clench. We'll check adjacent teeth and any that have large fillings or previous root canals, since those are the most vulnerable. Catching a stress fracture before it becomes a full crack often means a smaller, cheaper treatment.
