Cracked teeth can be a real mystery. At first, you may feel a sharp pain when biting down on something hard, but then it vanishes. Sometimes, it returns, leaving you wondering what’s going on with your tooth. This is where the bite test for cracked teeth comes in handy. This diagnostic tool helps dental practitioners detect elusive cracks, which can be symptomatic of cracked tooth syndrome (CTS).
In this blog, we’ll explore how bite tests work, why cracked tooth syndrome is tricky to diagnose, and what treatment options are available to restore the health of affected teeth. From understanding the types of tooth fractures to learning about the risks of invasive procedures, you’ll gain insight into how your dental health can be safeguarded with the right approach.
What Is a Bite Test for Cracked Tooth?
A bite test is a simple but effective tool that helps identify cracks in teeth, especially in posterior teeth like molars and premolars. Dentists use instruments like a “tooth slooth” or rubber abrasive wheels to apply biting pressure on specific areas of the tooth. This test is often key in detecting cracked teeth, particularly when the crack is hard to spot through traditional clinical examinations.
When a patient bites down, they may feel a sharp pain, indicating the presence of a cracked tooth or incomplete tooth fracture. A bite test might be your dentist’s go-to solution if you’re experiencing tooth pain that flares up when chewing.
What Causes a Cracked Tooth?
Cracked teeth can happen for various reasons. The most common causes include:
- Biting on Hard Objects: Chewing on tough items such as ice, nuts, or hard candies can lead to tooth fractures, particularly if the tooth is already compromised or weakened.
- Trauma or Injury: An injury or trauma to the face or mouth, often from sports injuries or accidents, can lead to tooth fractures. Even less forceful impacts, such as accidentally biting down on a fork, can result in cracks.
- Grinding or Clenching Teeth: Bruxism, the habit of grinding or clenching teeth (especially during sleep), can put excessive pressure on teeth, leading to cracks over time.
- Large Fillings or Dental Restorations: Teeth that have undergone extensive dental treatment, such as large fillings, crowns, or restorations, can become weakened and more prone to cracking.
- Wear and Tear with Age: Over time, our teeth naturally wear down, making them more susceptible to cracks. Older individuals often experience more enamel cracks and fractures.
- Sudden Temperature Changes: Eating something extremely hot and then drinking something cold (or vice versa) can cause rapid temperature changes in the mouth, potentially leading to cracks in the teeth.
- Poor Oral Health: Teeth affected by dental caries (cavities) or gum disease are more vulnerable to cracking because they are structurally compromised.
The location and depth of the crack in the affected tooth will determine the severity of the issue. Cracked tooth syndrome (CTS) often affects posterior teeth because of the high biting forces they endure. By being mindful of these causes and taking preventative actions, you can minimise the risk of developing cracked teeth. Regular dental visits are also essential for identifying early signs of tooth weakness before cracks occur.
Cracked Tooth Syndrome (CTS): The Silent Culprit
Cracked tooth syndrome (CTS) occurs when a tooth has a crack that hasn’t yet split the tooth apart but is deep enough to cause discomfort, especially under biting pressure. It’s a notoriously difficult condition to diagnose because cracks can be microscopic and may not show up on traditional dental X-rays. CTS is typically identified in vital posterior teeth, where biting pressure exacerbates pain.
Common signs of cracked tooth syndrome include:
- Sharp pain when chewing or biting
- Sensitivity to hot or cold temperatures
- Pain that comes and goes unpredictably
- Discomfort when releasing bite pressure
Because cracks are so elusive, dental practitioners rely heavily on bite tests and clinical examinations to diagnose CTS. In certain cases, more advanced imaging methods like a cone beam CT scan or microscopic evaluation may be needed to reveal fracture lines or detect cracks that would otherwise remain hidden.
Types of Cracked Teeth and Tooth Fractures
Tooth fractures can range from minor enamel cracks to severe cases like split teeth or vertical root fractures. The magnitude of the crack usually decides if the tooth can be repaired or if tooth loss is inevitable.
Here are some common forms of cracked teeth:
- Craze lines: superficial cracks in the enamel that often don’t cause pain. These cracks are more common as we age and don’t require treatment.
- Fractured cusp: When a cusp (the pointed part of the tooth) breaks off. This usually doesn’t affect the dental pulp and can be repaired with composite resin restorations or crowns.
- Cracked tooth: A crack that runs from the chewing surface down toward the gum line. This type of crack can sometimes affect the dental pulp and may require root canal treatment to save the tooth.
- Split tooth: When a crack splits the tooth into two distinct pieces. This type of fracture is more severe and often leads to tooth loss.
- Vertical root fracture: A crack that starts in the root and moves toward the chewing surface. Vertical root fractures are challenging to treat and may require extraction.
Diagnosing Cracked Tooth Syndrome: The Role of the Bite Test
During a bite test, the patient is asked to bite down on a small, hard object, such as a tooth slooth or stainless steel orthodontic bands, while the dentist monitors their reaction. If the patient feels a sudden, sharp pain when biting on a specific spot, it could indicate a crack in the tooth.
However, detecting cracked teeth isn’t always straightforward. While the bite test is useful, additional diagnostic tools like cone beam CT scans, periodontal probing, or imaging cracks using microscopic techniques may be necessary. These methods allow dental professionals to evaluate the tooth’s structural integrity and detect cracks that are not visible during a clinical examination.
Early Diagnosis of Cracked Teeth: Why It Matters
Cracks often worsen over time if left untreated, potentially leading to severe complications such as pulpal inflammation, dental infections, or even catastrophic failure of the tooth. Early diagnosis of a cracked tooth can save the tooth from further damage and avoid invasive procedures like extractions or extensive restorative treatments.
If detected early, cracks in the enamel or dentin can often be treated with minimally invasive procedures like composite resin restorations. For deeper cracks that reach the dental pulp, root canal treatment may be crucial to remove the affected tissue and restore the tooth’s function.
Treatment Options for Cracked Teeth: What to Expect
After diagnosing a cracked tooth, the treatment approach will be based on the crack’s location and severity. Here are some common treatment options:
- Composite resin restorations: Minor cracks can often be repaired with tooth-coloured composite materials, which restore the tooth’s structure and prevent further crack propagation.
- Crowns: If the crack affects a large portion of the tooth, a crown may be necessary to protect it from further damage. Crowns are customised coverings that encircle the entire tooth, offering long-term protection.
- Root canal treatment: Root canal treatment may be critical to remove the damaged tissue and prevent infection for cracks that extend into the dental pulp. A crown often follows this procedure to restore the tooth’s strength.
- Extraction: Extraction may be the only option in cases of severe cracks, such as split teeth or vertical root fractures. While tooth loss is a possibility, there are replacement options like dental implants to restore function and aesthetics.
Preventing Cracked Teeth: Protecting Your Oral Health
Prevention is always better than cure. Here are some tips to avoid cracked teeth:
- Avoid biting on hard objects like ice, candies, or pens.
- Use a nightguard to protect your teeth if you tend to grind them while sleeping.
- Seek treatment for dental caries or weakened dental restorations before they worsen.
- Visit your dentist regularly for frequent check-ups and cleanings.
- If you engage in contact sports, use a mouthguard to protect your teeth from trauma.
The Importance of Early Detection and Diagnosis
Cracked teeth can be tricky to spot, but with tools like bite tests and advanced imaging techniques, dental practitioners can accurately diagnose and treat tooth fractures. Early diagnosis is key to preventing tooth loss and ensuring successful restorative management of symptomatic cracked teeth.
If you suspect you have a cracked tooth or are experiencing atypical facial pain when biting down, don’t hesitate to contact your emergency dentist for an evaluation. A thorough dental history, clinical examination, and imaging can help detect cracks early and prevent further damage.
Keep in mind that your oral health is important, and untreated cracked teeth can result in the need for more complex dental treatments. Stay proactive and keep your smile healthy by addressing any signs of tooth fractures or discomfort early on.
