Can a Crown be Replaced?

Dental crowns are a unique and efficient way of restoring and rebuilding cracked or broken teeth. It works like a tooth cap that helps to increase the life of your natural teeth. While dental crowns can last very well for around 10 to 15 years, every crown is designed differently and may have to be repaired or replaced earlier. To determine when your crown needs to be replaced or repaired, your dentist will need to examine it. Is crown replacement possible? When is it needed and how is a crown replaced? Here is everything you need to know!

What are Dental Crowns?

Dental Crowns

Dental crowns are described as a restorative option for protecting teeth that are weakened from fracture or decay. If decay has caused damage, the filling doesn’t work since too little of the tooth is left. In this case, dental crowns, also called caps, are useful for replacing discolored, misshapen, or broken teeth. 

Sometimes, if the crowned tooth suffers too much damage or decay, it may not be replaced with another crown, so a dental bridge or implant may be a suitable option. 

While dental crowns are designed to last for a good 10 to 15 years, they can sometimes need a repair or replacement before that. So, in that case, you will need to get your crown replaced with a new one. Your dentist will examine your crown and see whether it needs to be replaced. How to replace a crown? You’ll know about it ahead.

Why Do You Need to Replace Your Crown?

There are several reasons for replacing a crown. Here are some signs to consider as they can be a pointer towards needing a new crown. 

Damage

All crowns can undergo damage, even the zirconia and gold ones that are least likely to be damaged. This can be because of trauma to your mouth or biting something hard. If you feel that the edges of your crown are rough, try making a visit to the dentist for crown repair or replacement. Chewing and biting regularly can reduce the life expectancy of the crown. This is especially true when hard substances are chewed or acidic beverages are taken. While the acid corrodes the crown, hard foods can damage the surface. If the crown seems odd or worn out, you may need to get it repaired or replaced.

Infection

While a crown can offer protection the same as the tooth enamel, it can still get cavities or infections. In some cases, the crown will need to be removed and replaced to treat or fill the cavity developed. In the case of an abscess, antibiotic treatment is used to end infection but if it doesn’t work, you’ll need to remove the crown to drain the abscess. This is later replaced by a new crown.

Receding of the Gum Line

A crown designed from synthetic material can result in plaque and bacteria collecting around the site that can lead to receding gums. While this can often be because of poor oral hygiene, it may be because of a poorly set crown. If you experience any gum sensitivity around the crown, visit your dentist as soon as possible.

The Crown Doesn’t Look Good Anymore

In some cases, cosmetics can be enough of a reason to get a crown replaced. Those having porcelain crowns mixed with metal may see a dark line appear along with the teeth. This is because the metal of the crown is showing. In such a case, sometimes the dentist may recommend the replacement of the crown.

The Crown is Very Old

Sometimes, even when any physical signs aren’t evident, your crown may need a replacement when it has lived its lifespan. While the lifespan depends on the way your crown is used and its material, your crown should be replaced after 10 or 15 years. When this time span is complete, your dentist may recommend a crown replacement.

How Often Do Dental Crowns Need to be Replaced? 

Why Dental Crowns Need to be Replaced

Dental crowns are a common solution to replace teeth that have become damaged, if the pulp has become infected, or if a root canal is required. Nevertheless, it can sometimes be because of cosmetic reasons. The lifespan of your crown will depend on multiple factors, most importantly the material that is used to make them. Porcelain crowns, while being the most popular, are also the least expensive and can last around 15 years. Metal crowns can last about 20 years or more, with Zirconia or Gold crowns lasting a lifetime. 

Nevertheless, under some circumstances, a crown may need an earlier replacement before the life expectancy is complete. Some cases of “wear and tear” can cause the crowns to damage before time. Here are some mouth-related habits that can cause wear and tear to your crowns.

  • Chewing on ice
  • Biting fingernails
  • Clenching or grinding the teeth
  • Opening packing with your teeth

How Are Dental Crowns Replaced?

The process of crown replacement depends on the crown type you have, but the process is rather simple. To remove the crown, your dentist may use soft adhesive to ease the removal. While this is the case of removing most crowns, the removal of permanent ones is more challenging. The process is described below.

  • The dentist will start by numbing the area around the gums to minimize discomfort. 
  • To weaken the cement around the crown, an adhesive may be used. Sometimes the old crown may be reused if it isn’t damaged too much. In most cases, however, a new crown is used especially if the prior crown is discolored. 
  • The teeth are then cleaned to remove decay and debris. The dentist may use a root canal process to get rid of decay.
  • Next, the dentist will take your teeth impression to make the crown again. This can take around four weeks. During this time, temporary crowns will be used to cover the teeth. 
  • After your new crowns are prepared, they will be fixed with the same procedure as the previous.

Permanently cemented or casted crowns require certain techniques to be removed and replaced. The current state of the crown determines the method used for replacement. These opportunities have three categories. 

Destructive

This is a condition where the damaged crown is not capable of being reused. The method involves cutting a section of the crown with a speedy rotary instrument, enabling the crown to be levered and pried from the tooth.

Semi-Conservative

In this crown removal process, the crown undergoes minimal damage and can be reused potentially. In this method, the crown will be cut completely from the exposed hole, breaking the seal of cement and lifting the crown from its place.

Conservative

In this method of crown replacement, the crown may be removed while staying intact. In this method, the crown is removed by the application of a certain that breaks the cement seal and releases the crown.

Dental crowns are a great replacement option for broken or damaged teeth. These tend to be a long-term solution and can last 10 or 15 years if taken care of.
