What are the disadvantages of zirconia crowns?

Answered by Jason Smith

As an expert in dental care, I can provide you with a detailed answer regarding the disadvantages of zirconia crowns. While zirconia crowns are generally considered a reliable and aesthetically pleasing option for dental restorations, there are a few potential drawbacks to consider.

One concern is the material’s toughness, which may cause friction against the tooth root. This friction could potentially result in damage or irritation to the surrounding tissues. However, it is important to note that this risk is minimal and can be mitigated by regular check-ups with your dentist. During these check-ups, your dentist can evaluate the fit and function of the crown, ensuring that it is not causing any harm to your tooth root or surrounding tissues.

Another potential disadvantage is the possibility of wearing down opposing teeth. Zirconia crowns are highly durable and can withstand the forces of biting and chewing. However, in some cases, the hardness of the zirconia material may cause excessive wear on the opposing teeth when in contact during biting or grinding motions. This can lead to the need for additional dental work in the future, such as fillings or crowns on the opposing teeth.

To minimize the risk of wearing down opposing teeth, it is essential to have regular dental visits for check-ups and cleanings. Your dentist can monitor the condition of your zirconia crown and address any concerns about wear on the opposing teeth. They may also recommend the use of a nightguard if you have a habit of grinding your teeth while sleeping, as this can help protect both your zirconia crown and your natural teeth from excessive wear.

While zirconia crowns have minimal disadvantages, it is important to be aware of the potential for friction against the tooth root and wearing down opposing teeth. Regular check-ups with your dentist can help mitigate these risks and ensure the longevity and functionality of your zirconia crown. By maintaining good oral hygiene practices and following your dentist’s recommendations, you can minimize any potential drawbacks and enjoy the benefits of a durable and aesthetically pleasing dental restoration.
