Can You Put a Crown on a Cracked Tooth?
A cracked tooth is a serious dental problem, and whether or not you can put a crown on it depends entirely on the severity and location of the crack. While a crown is often the solution, it's not always the best option, and sometimes other treatments are necessary. This comprehensive guide explores the possibilities and helps you understand what to expect.
What Happens When a Tooth Cracks?
A cracked tooth, also known as a fractured tooth, can range from a minor surface crack (fracture) to a significant break extending deep into the tooth's root. The severity of the crack dictates the necessary treatment. Minor cracks may only require monitoring, while more severe cracks necessitate restorative work to prevent further damage and save the tooth. The location of the crack is also crucial—a crack in the cusp (the raised point of the tooth) is different from a crack that extends down the root.
Can a Crown Fix a Cracked Tooth?
Yes, a crown can often successfully repair a cracked tooth, particularly those with cracks that don't extend below the gum line. A dental crown is a cap placed over the entire tooth, essentially protecting it from further damage and restoring its shape, strength, and function. The dentist will carefully prepare the tooth by removing a layer of enamel and dentin, then take an impression to create a custom-fitting crown. This is generally made of porcelain or ceramic for a natural-looking finish, or metal for increased durability.
What Types of Cracked Teeth Can Be Treated with a Crown?
- Craze lines: These are tiny, superficial cracks that usually don't require treatment.
- Fractured cusp: A crack confined to a cusp can often be repaired with a crown, restoring the tooth's biting surface.
- Vertical root fracture: This is a serious crack extending down the root. A crown is unlikely to be successful here, and other treatments like root canal therapy or extraction might be necessary.
What if a Crown Isn't the Right Solution?
If the crack is extensive, reaches the root, or involves significant damage to the tooth's pulp (the soft tissue inside), a crown alone may not be sufficient. In these cases, other treatments might be necessary:
- Root canal therapy: If the pulp is infected or inflamed due to the crack, a root canal is required to remove the infected tissue and save the tooth. A crown is often placed after a root canal to protect the weakened tooth.
- Extraction: In severe cases, particularly with vertical root fractures, extraction might be unavoidable. This can be followed by placement of a dental implant, bridge, or partial denture to replace the missing tooth.
How Do I Know if I Need a Crown or Other Treatment?
Only a dentist can accurately diagnose the extent of a cracked tooth and recommend the appropriate treatment. If you suspect you have a cracked tooth, schedule an appointment immediately. Symptoms may include pain when chewing, sensitivity to temperature changes, or a visible crack in the tooth. Early diagnosis and treatment are crucial to maximizing the chances of saving the tooth.
What are the Alternatives to Crowns for Cracked Teeth?
Depending on the severity and location of the crack, alternatives to crowns might include dental bonding (for minor cracks), fillings (for small cracks in the cusps), or onlays (for larger cracks). Again, a dentist’s examination is essential for determining the best course of action.
How Long Does a Crown Last on a Cracked Tooth?
With proper oral hygiene and regular dental checkups, a crown can last for many years, even on a previously cracked tooth. However, the longevity depends on factors like the severity of the initial crack, the quality of the crown, and the patient's oral health habits.
