Cracked teeth are a common dental problem and often require restorative procedures to prevent further damage. One of the most effective treatments is the application of a dental crown. But how exactly does a crown help in fixing a cracked tooth, and is it the best option for every type of crack?

In this comprehensive article, we’ll explore the role of crowns in repairing cracked teeth, when they are needed, the materials used, and what to expect during and after the procedure.

What Types of Cracks Can Be Fixed With a Crown?

There are several types of tooth cracks, and not all require the same treatment. Here’s a breakdown of common cracks and when a crown is recommended:

1. Craze Lines: These are tiny, shallow cracks that only affect the enamel. They’re mostly a cosmetic issue, so a crown is not usually necessary.

1. Fractured Cusp: This crack usually occurs around a dental filling, where part of the tooth’s chewing surface breaks away. A dental crown is often used to protect the remaining tooth structure.

1. Cracked Tooth: A more serious crack that extends from the chewing surface towards the root. In many cases, a crown can stabilise the tooth, preventing the crack from worsening.

1. Split Tooth: A severe crack that splits the tooth into two distinct parts. While a crown might help if caught early, a split tooth often requires extraction.

1. Vertical Root Fracture: A crack that starts in the root and moves upwards. Unfortunately, crowns typically do not help in these cases, and more extensive treatment, including potential extraction, may be needed.

How Does a Crown Fix a Cracked Tooth?

A dental crown acts like a protective cap, covering the cracked or damaged tooth and holding it together. This prevents further damage while restoring functionality, allowing the tooth to withstand biting and chewing forces.

Procedure for Applying a Crown:

1. Initial Assessment: The dentist will first assess the severity of the crack. X-rays may be taken to ensure that the crack has not affected the tooth root or surrounding bone.

1. Tooth Preparation: Once it is confirmed that a crown is needed, the tooth is reshaped to accommodate the crown. This involves removing part of the tooth enamel to create space for the crown.

1. Impression Taking: The dentist will then take an impression of the tooth, which will be used to create a custom-made crown that fits perfectly.

1. Temporary Crown: In many cases, a temporary crown will be placed while the permanent one is being fabricated.

1. Fitting the Crown: On the second visit, the permanent crown is fitted and bonded to the tooth. Adjustments may be made to ensure a comfortable bite.

1. Post-Crown Care: After receiving a crown, it’s essential to maintain good oral hygiene to prolong the crown’s lifespan and prevent future complications.

What Are the Best Materials for a Crown?

Choosing the right material for your crown can have a significant impact on the outcome. Each material has its pros and cons, and your dentist will recommend the most suitable option based on the tooth’s location, function, and your budget.

How Durable Is a Crown for a Cracked Tooth?

Crowns are an excellent long-term solution for cracked teeth, but their durability depends on the material used, the tooth’s location, and how well you maintain your oral hygiene.

• Porcelain crowns, commonly used for front teeth, offer a natural appearance but are less durable than metal or zirconia crowns. With proper care, porcelain crowns can last around 5–10 years.

• Zirconia crowns are highly durable and suitable for molars where biting pressure is greatest. These crowns can last 15 years or longer with good care.

• Metal and Gold crowns are the most durable but less aesthetically pleasing. These can last decades but are typically used for less visible areas.

Factors Influencing Crown Lifespan:

• Material: As shown in the table, materials like zirconia and metal offer the longest lifespan.

• Oral Hygiene: Maintaining good dental hygiene, such as brushing twice a day and regular dental check-ups, ensures the crown stays intact.

• Avoiding Hard Foods: Excessive biting on hard objects or foods can reduce the crown’s longevity.

• Regular Dental Visits: Monitoring the condition of the crown during routine check-ups helps catch potential issues early.

When Is a Crown Not Enough?

Although crowns are highly effective for most cracked teeth, there are situations where a crown alone may not suffice.

1. If the Crack Extends Below the Gum Line: If the crack reaches below the gum line or into the root, a crown may not be enough to save the tooth. In these cases, a root canal treatment or extraction might be necessary.

1. Extensive Tooth Damage: If the crack is part of a more extensive fracture, such as a split tooth or vertical root fracture, alternative treatments like extraction and implants might be required.

1. Pain and Infection: If the tooth is infected or if the crack exposes the pulp, a crown may need to be paired with a root canal treatment to save the tooth.

Can a Root Canal Be Needed Before Placing a Crown?

A root canal is not always necessary before placing a crown. However, if the crack has reached the inner pulp of the tooth, causing infection or significant pain, a root canal is required to remove the damaged tissue before the crown is placed.

Steps for Root Canal and Crown Combination:

1. The root canal is performed to remove the infected pulp.

1. The tooth is then sealed and prepared for the crown.

1. A crown is placed to protect the remaining structure and restore functionality.

Research shows that combining a root canal with a crown can significantly increase the tooth’s longevity, especially in cases of severe cracks.

What Is the Cost of a Crown for a Cracked Tooth?

The cost of a crown can vary depending on several factors, including the material used and the dentist’s expertise. On average in Australia, crowns can range from AUD $1,200 to AUD $2,500. The price may be higher for premium materials like zirconia.

Cost Breakdown:

• Porcelain Crowns: AUD $1,200 – $1,800

• Zirconia Crowns: AUD $1,500 – $2,500

• Gold Crowns: AUD $1,600 – $2,200

It’s always advisable to check with your health insurance provider as they may cover part of the cost, depending on your policy.

What Should You Expect After Getting a Crown?

After your crown has been placed, it’s essential to follow some guidelines to ensure the tooth heals well and the crown stays intact.

Post-Crown Care Tips:

1. Avoid chewing hard or sticky foods for the first few days.

1. Continue with your usual oral hygiene routine—brushing and flossing around the crown carefully.

1. Use a soft-bristled toothbrush to prevent scratching the crown surface.

1. Schedule regular dental check-ups to monitor the crown’s condition.

Crowns can last for many years if well cared for, but it’s crucial to pay attention to any changes in sensation or discomfort around the crowned tooth.

FAQs on Crowns for Cracked Teeth

1. Can a crown fix any type of cracked tooth? A crown can fix many types of cracked teeth, but not all. It is most effective for cracks like fractured cusps and cracks that extend toward the root without affecting the tooth pulp. However, more severe cracks, such as split teeth or vertical root fractures, may require alternative treatments, including extractions.

1. How long does a crown last on a cracked tooth? The lifespan of a crown depends on the material used and how well it is cared for. Porcelain crowns typically last 5–10 years, while zirconia or metal crowns can last 15 years or more. Maintaining good oral hygiene and regular dental check-ups can help prolong the life of the crown.

1. Will a cracked tooth hurt after getting a crown? Mild discomfort or sensitivity is common after receiving a crown, especially if the tooth was cracked. This discomfort usually subsides within a few days. If pain persists or worsens, it’s important to consult your dentist, as further treatment such as a root canal may be needed.

1. Is a root canal always necessary before getting a crown for a cracked tooth? No, a root canal is not always necessary. A root canal is only required if the crack has reached the tooth’s pulp, causing infection or severe pain. If the crack is less severe and does not affect the pulp, a crown alone is sufficient to protect the tooth.

1. How much does it cost to get a crown for a cracked tooth? In Australia, the cost of a crown can range from AUD $1,200 to AUD $2,500 depending on the material and the complexity of the case. Porcelain crowns are generally on the lower end of the spectrum, while zirconia and gold crowns are more expensive.

1. What should I do if my crown feels loose after being placed on a cracked tooth? If your crown feels loose, contact your dentist immediately. A loose crown can allow bacteria to get under it, leading to decay or further damage to the cracked tooth. Your dentist may need to adjust or re-cement the crown to ensure it fits properly.
