Why Are Dental Crowns So Easy to Break

Dental crowns are a common dental treatment used to restore damaged teeth, but they are not immune to damage themselves. Many patients find themselves surprised when their dental crowns break or become damaged, leading to discomfort and the need for additional dental work. So, why are dental crowns so easy to break? In this article, we will explore 10 factors that contribute to the vulnerability of dental crowns and discuss potential solutions.

1. Material Quality

The quality of materials used in dental crowns plays a significant role in their strength and durability. While high-quality porcelain or ceramic crowns can be incredibly strong, cheaper materials may be more prone to breaking. It is crucial to work with a reputable dentist who uses premium materials to ensure the longevity of your dental crown.

Price Range: On average, porcelain or ceramic crowns cost between $800 to $3,000, depending on the location and specific dental clinic.

2. Insufficient Tooth Structure

If a tooth has substantial decay or damage, it may require extensive restoration before a dental crown can be placed. In some cases, there may not be enough tooth structure left to support a crown adequately. In these situations, the weakened tooth may be more susceptible to fractures or breakage.

3. Bruxism

Bruxism, or teeth grinding and clenching, can put excessive pressure on dental crowns, leading to their eventual failure. The constant force exerted on the crown can cause cracks or fractures over time. Dentists often recommend wearing a nightguard for individuals who grind their teeth to protect the crown and promote its longevity.

4. Improper Bite Alignment

If a dental crown is not correctly aligned with the opposing teeth, it can create an uneven bite force distribution. This excessive force on specific areas of the crown can cause weakness and result in a higher risk of breakage. Regular dental check-ups can help identify and address any bite alignment issues.

5. Trauma or Injury

Dental crowns are designed to withstand normal chewing forces, but they may not be able to withstand trauma or injury. Accidents or blows to the mouth can cause dental crowns to crack or break. In such cases, immediate dental attention is necessary to evaluate the damage and replace the crown if needed.

6. Tooth Grinding Habits

Aside from bruxism, habits such as chewing on hard objects like ice, pens, or fingernails can weaken dental crowns and make them more prone to breakage. It is essential to avoid using your teeth as tools and instead opt for appropriate tools for tasks.

7. Age of the Crown

Over time, even the most durable dental crowns can weaken or deteriorate. It is recommended to replace dental crowns every 10 to 15 years to maintain optimal functionality. Aging crowns may develop cracks or fractures, making them more susceptible to further damage.

8. Improper Oral Hygiene

Poor oral hygiene can contribute to the deterioration of dental crowns. Bacterial plaque buildup around the gum line can lead to gum disease, which in turn can weaken the supporting structures of the crown. Maintaining a proper oral hygiene routine, including regular brushing, flossing, and dental check-ups, can help prevent these issues.

9. Improper Crown Placement

The success and durability of a dental crown depend on proper placement. If a crown is not fitted correctly or if there are issues with the cementation process, it may become loose or unstable, leading to potential fractures or breakage. Working with an experienced dentist is crucial to ensure proper crown placement.

10. Biocompatibility

In rare cases, patients may experience adverse reactions to the materials used in dental crowns, resulting in inflammation or gum irritation. This can weaken the crown's bond and increase the risk of breakage. Dentists should carefully consider the patient's medical history and potential allergies when choosing crown materials.

Frequently Asked Questions

1. Can a broken dental crown be repaired?

In some cases, a broken dental crown can be repaired. However, the extent of the damage and the crown's material will determine whether repair or replacement is the best option. It is essential to consult with your dentist to assess the situation and determine the appropriate course of action.

2. How long does a dental crown typically last?

Dental crowns can last anywhere between 10 to 15 years on average. However, with proper care and regular dental check-ups, they can sometimes exceed 15 years. It is essential to monitor the crown's condition and seek professional advice if any issues arise.

3. Can dental insurance cover the cost of repairing a broken crown?

Dental insurance coverage varies depending on the specific plan. While some insurance plans may cover a portion of the cost for repairing a broken crown, others may not provide coverage for repairs and only cover crown placement. It is advisable to check with your insurance provider to understand their coverage policies.
