That sudden, sharp pain when you bite down on something can be alarming, especially when you suspect it might be a cracked tooth.
If you’re reading this, you’re probably wondering the same thing many patients ask: ‘Will I lose my tooth?’
The answer is probably not: most cracked teeth can be saved with the proper treatment approach.
In fact, only 3% of cracked teeth will fracture, and only 12% will show crack progression in three years. Lack of pain and minimal teeth movement usually means you have a better chance of saving the tooth.
What Causes a Cracked Tooth?
Other contributing factors include large dental fillings that weaken tooth structure, facial injuries from accidents or sports, and sudden temperature changes that cause teeth to expand and contract rapidly.
Tooth cracks may also result from biting down on hard things, clenching during sleep, or an uneven bite. Large fillings, injuries, and sudden shifts in temperature also increase the risk of tooth cracks.
Habitually chewing on tough objects such as popcorn kernels, candies, pencils, and rice cubes may put excessive pressure on teeth, eventually causing minor fractures.
When your bite is uneven, certain teeth bear more of the force than others during chewing. This unequal pressure distribution increases your risk of developing cracks in those teeth. Teeth cracks are endemic; studies show that 70% of adults have at least one posterior tooth with visible cracks.
Teeth grow less durable and more brittle with age, increasing the possibility of a tooth breaking or cracking.
Types of tooth cracks
Understanding what causes cracks helps, but knowing the different types is equally essential for treatment decisions. Dental professionals classify tooth cracks into four categories based on their location and severity.
- Craze Lines are the mildest cracks, tiny ones confined to the tooth enamel. They don’t cause pain, but can cause cosmetic concern to some.
- The cracked cusp goes from the chewing surface to the gumline. It doesn’t reach the pulp and causes mild pain when biting down.
- A split tooth is a significant crack that frequently separates the tooth from the root below the gum line. It causes excruciating pain, swelling, and sensitivity to heat and cold.
- Vertical root fractures- While less common, vertical root fractures may result in tooth loss.
Symptoms of a cracked tooth
Now that you understand the different types of cracks, let’s explore how to recognize if you might have one. Cracked teeth don’t always cause noticeable symptoms, causing many cases to go undiagnosed.
Cracked teeth typically present with several telltale signs. You may experience sharp pain when biting down, increased sensitivity to temperature changes or sweet foods, general discomfort, localized swelling, or visible crack lines on the tooth surface.
If you suspect you have a cracked tooth, see your dentist immediately. Early diagnosis and treatment are crucial for preventing further damage and saving your natural tooth.
Treatment Options for Cracked Teeth
Your dentist will carefully evaluate the crack’s type and severity before recommending the most appropriate treatment to restore the look and function of the affected tooth.
- Dental bonding is a good option for repairing small cracks, especially craze lines that remain within the enamel. A tooth-colored filling material is applied and shaped to conceal the fracture and completely preserve the tooth’s structure.
- Dental crowns: Dental crowns are a good option for deeper cracks or cracks that affect the overall tooth structure. A crown is a custom-made cover that fits the whole tooth and offers improved stability, strength, and appearance.
- Root canal therapy: If the crack reaches the pulp, the nerves and blood vessels are exposed, making root canal therapy necessary. This procedure removes the infected pulp, clearing and sealing the inside space to prevent further infection. Your dentist will typically place a crown after root canal treatment. Studies show an 84.1% success rate for root canal treatment of cracked teeth at 5 years.
- Tooth extraction: In cases where the damage is extensive and beyond repair (extensive caries, vertical root fracture, crack extending up to the root), extraction is the only option left.
Does a cracked tooth always need to be pulled?
The answer to ” Does every cracked tooth need to be pulled out?” is thankfully a resounding no!
Modern dentistry provides a variety of treatments to save damaged teeth when possible. The right and best treatment option for your damaged tooth will depend on several factors, including the type and extent of the crack, your symptoms, and the tooth’s overall health.
Before considering extraction, your dentist is going to consider these factors carefully:
Location and extent of crack: Cracks extending deeper into the tooth or reaching the pulp require more extensive treatment, but do not necessarily need to be extracted. Small, hairline cracks in the enamel (craze lines) typically don’t require extraction.
Symptoms: Sensitivity, pain, or swelling might indicate the need for medication, but not extraction.
Overall condition of the affected tooth: If it is already severely damaged, grossly decayed, or has large fillings, it might be beyond repair.
Alternative Treatment Options to Extraction
Depending on the case, dentists might be able to repair or restore an affected tooth through different treatments, such as root canal therapy, dental bonding, and dental crowns.
Conclusion
A crack in your tooth isn’t automatically a death sentence (extraction) for that tooth.
Today’s dentistry offers numerous ways to preserve your natural teeth, and most cracks can be successfully treated without extraction.
The key is early detection and proper treatment. If you suspect you have a cracked tooth, don’t wait—schedule an appointment with your dentist promptly.
With timely intervention, you can keep your natural smile intact and avoid more complex procedures.
