How to Know When You Need to Replace a Crown?

replace a crown

A dental crown is a cap placed over a tooth to cover it and restore its former shape, size, and strength to enhance its appearance. Once cemented, dental crowns enclose a tooth’s visible part above the gum line entirely.

Dental crowns are meant to replace a previous tooth that has suffered a fracture due to an accident or disease or has deteriorated over time. This way, dental crowns, made of a material similar to the tooth, allow the user to chew and drink their food without worries.

However, this does not mean that the issue of dental crowns should be taken lightly because even though they are not natural teeth, if they are not taken care of, they can harm other teeth or reduce their lifespan. Therefore, it is important to comply with the dentist’s instructions so that the dental crown does not generate problems for the patient.

The dental crown placement will depend mainly on the dentist’s decision since sometimes this is not an option. 

This means that before requesting a dental crown, an evaluation should be made with a dentist so that a decision can be made as to whether or not a dental crown will be needed. Some reasons why a dental crown may be required are:


  • Because the tooth has a cavity that is too large to be solved with a filling.
  • Because the tooth is weakened or cracked.
  • Because the tooth has become more fragile due to root canal treatment.
  • Because the tooth is discolored or poorly formed and therefore it is necessary to improve its appearance.

Signs That You Need to Replace a Crown

While dental crowns are not forever in the sense that they should be replaced within 15 to 20 years (as this is their lifespan), some factors could influence the need to replace a crown with another one. There are five main reasons why this could happen, which are:

  • Worn crown: There are many reasons why dental crowns can wear down even faster than an ordinary tooth. First, this wear could occur from eating very hard foods, such as nuts or hard candy. The second reason would be certain habits, such as chewing objects, which will cause the dental crown and other teeth to wear down precipitously. Thus, when a dentist needs to replace a crown due to wear and tear should be done quickly to prevent it from affecting the mouth’s health.

  • Loose or broken crown: It is possible that the dental crown loosens or breaks over time or for some external reason. If, for any reason, the patient feels that his dental crown is loose, it is necessary to go immediately to the dentist since, in this way, the dentist will be the one who will decide whether to replace a crown or simply adjust it. In the case that the dental crown has broken, then it will be mandatory to replace a crown with another one; the reasons why a dental crown can break are due to certain habits such as those mentioned in the previous point, so it is necessary to do everything possible to avoid doing them.

  • Pain or discomfort in the crown area: As with any other dentistry service, if the patient has any type of pain or discomfort, it is necessary to visit the dentist. Sometimes this pain is caused because the gum is in the process of adapting to the dental crown; however, no conclusions should be drawn until you visit the dentist and indicate whether or not it will be necessary to replace a crown.

  • Caries or infection under the crown: As mentioned in the previous point, during the recovery process, the gum is in the process of adaptation, so there may be some gaps that make the part under the crown exposed to some kind of infection. One could be the famous cavities that can appear under dental crowns, although many patients do not believe it. It should be remembered that this crown functions as a sheath, so part of the tooth is still in the mouth. Tooth decay is more common than it seems, and if it is not treated in time, it can infect and rot other teeth, cause the sufferer bad breath, and generate unbearable pain. If they do spread, then it is very likely that replacing a crown will be necessary.

  • Fractured or broken tooth under the crown: In some cases, patients suffer some kind of fracture in the tooth under the dental crown, which forces them to replace a crown.


While these are not the only reasons patients need to replace a crown, they are the main reasons. Other reasons for needing a crown replacement may be due to dental crowns that no longer match the surrounding teeth, so to replace a crown would be necessary.

Factors that Affect the Lifespan of a Crown

Some factors should be taken into account if you do not want to replace a crown and that, on the contrary, it lasts for a long time. The first one would be the material the dental crown is made of. Currently, the most popular materials are ceramic crowns and zirconia crowns, both of which have the benefit of being a material very similar to that of teeth.

Of course, for a dental crown to last, it is necessary to have excellent dental service. When referring to the service, the preparation and experience of the dentist are taken into account when placing a dental crown. In addition, it will also be necessary to know if the dentist and the clinic have the certificates required to perform this and any other type of dentistry service needed. 

A good diet will help avoid having to replace a crown in a short time. Eating healthy decreases the chances of getting a disease such as cavities or oral cancer. By doing so, you will benefit not only the lifespan of the crown but also the rest of your teeth.

Long-lasting dental crowns

Taking care of the dental crowns will be essential to avoid having to replace a crown every so often. Thus, patients are responsible for following the dentist’s instructions, so they do not have to worry that their dental crown will not allow them to enjoy their favorite foods.

The use of dental crowns does not guarantee total protection against any other type of anomaly or disease, so it is necessary to have a dental treatment that helps to avoid any kind of inconvenience. It is for this same reason that you should not miss the appointments that have been scheduled with the dentist in question since attending will guarantee the duration of the crowns and oral health.
