Dental crowns are a popular restorative treatment designed to cover and protect damaged or decayed teeth. They can restore both the function and appearance of your teeth, providing a long-lasting solution for those who need extra support. However, many patients at McLevin Dental Clinic ask whether crowns will eventually crack or break over time. While crowns are designed for durability, like any dental restoration, they can be susceptible to wear and tear under certain conditions.
In this blog, well explore the factors that can affect the longevity of crowns and help you understand whether or not they will inevitably crack.
What Are Dental Crowns?
A dental crown is a cap that is placed over a damaged or weakened tooth to restore its size, shape, strength, and appearance. Crowns are made from various materials, including porcelain, ceramic, metal, or a combination of these. Each type has its own benefits, depending on the location of the tooth and the patient’s specific needs.
Crowns are commonly used to:
Restore teeth that are broken or severely worn down
Protect a tooth that has undergone a root canal
Improve the appearance of discolored or misshapen teeth
Support dental bridges
When properly cared for, dental crowns can last for many years, but they are not indestructible. Factors such as material, maintenance, and lifestyle habits can all influence how long they last.
Factors That Can Cause Crowns to Crack
While dental crowns are durable, they are not immune to damage. Here are some of the common reasons why a crown might crack or fail:
1. Poor Oral Hygiene
One of the most important factors in the longevity of your crown is maintaining good oral hygiene. Plaque and bacteria can accumulate around the crown, leading to gum disease or tooth decay beneath the crown. If the tooth underneath the crown becomes compromised, it can weaken the crowns support, making it more likely to crack. Regular brushing, flossing, and professional cleanings are essential to keep your crown and surrounding teeth healthy.
2. Bruxism (Teeth Grinding)
Bruxism, or the habit of grinding or clenching your teeth, is a leading cause of crown damage. People who grind their teeth, especially at night, apply significant pressure on their crowns, which can cause them to wear down or crack over time. If you suspect that you grind your teeth, talk to your dentist about using a night guard to protect your crowns and natural teeth from damage.
3. Trauma or Impact
Just like natural teeth, crowns can be affected by external forces. A blow to the face, such as from a sports injury or accident, can cause a crown to crack or break. If you have a crown in a tooth that is more prone to physical impact, like your molars, you should take extra precautions, such as wearing a mouthguard during sports or other activities.
4. Chewing Hard Foods
While dental crowns are designed to withstand everyday chewing, they are not invincible. Eating hard or sticky foods, such as ice, hard candy, or sticky toffees, can place excessive pressure on the crown, potentially causing it to crack. Its a good idea to avoid these types of foods or cut them into smaller pieces to reduce the stress on your crowns.
5. Old Age of the Crown
Dental crowns are durable, but they do have a finite lifespan. Over time, they may wear down, lose their structural integrity, or even begin to discolor. Depending on the material of the crown, it may be more susceptible to cracking or chipping as it ages. For example, metal crowns tend to last longer than porcelain crowns but may need to be replaced eventually.
Will All Crowns Eventually Crack?
Not all crowns will crack eventually, but it is a possibility. The lifespan of a crown depends largely on the material used, the location of the crown, and how well you care for it. High-quality crowns made from materials like porcelain fused to metal or all-ceramic crowns can last for many years, sometimes even up to 15 years or more, with proper care.
If you are careful about your oral hygiene, avoid habits like teeth grinding, and make sure to protect your crown from trauma, you can significantly extend its lifespan and reduce the risk of cracking.
How to Prevent Crowns from Cracking
To ensure the longevity of your crowns and prevent them from cracking prematurely, here are some tips to follow:
1. Practice Good Oral Hygiene
Brush your teeth at least twice a day with fluoride toothpaste, and floss daily to remove plaque and food particles from around the crown. Regular dental checkups at McLevin Dental Clinic are also important for monitoring the condition of your crown and detecting any issues early.
2. Wear a Night Guard for Bruxism
If you grind or clench your teeth at night, a custom-fitted night guard can protect your crowns from the pressure of grinding. Night guards act as a cushion and prevent the damaging forces of bruxism from affecting your dental work.
3. Avoid Chewing Hard or Sticky Foods
Be mindful of what you eat. Avoid chewing on ice, hard candy, or other foods that can stress your crowns. If you cant resist these treats, try breaking them into smaller pieces to reduce the pressure on your crowns.
4. Address Any Problems Early
If you notice any discomfort, sensitivity, or visible cracks in your crown, dont wait to address the issue. Promptly visiting McLevin Dental Clinic will allow your dentist to assess the condition of the crown and take action before the problem worsens.
5. Choose the Right Material
When selecting a crown, discuss the materials with your dentist. For those who want a highly durable crown that will last for many years, metal crowns may be a good option. However, for those who want a more natural appearance, porcelain or ceramic crowns may be better, though they may require a bit more care.
Conclusion
While not all crowns will inevitably crack, they are still susceptible to wear and damage, particularly if they are not properly cared for. The best way to ensure the longevity of your crown is to maintain good oral hygiene, avoid habits that can cause damage (like grinding), and visit your dentist regularly. By following these steps, you can enjoy the benefits of your dental crowns for many years to come.
