Dental Crown needs Repair or Replace


Although today’s dental crown are strong and durable, they are not likely to last the rest of your life. Most crowns last between five and 15 years before needing to be replaced (or at least repaired).


So How do you know when a Dental Crown needs a Repair or to be Replace?


In some cases it is obvious that you need to replace a crown because it has fallen out or suffered extensive damage; in other circumstances, it is less obvious that there is a problem with a crown. Ignoring signs of a problem could end up causing you pain and discomfort.

Below it discusses scenarios in which your dental crown may need to be replaced.

There can be a variety of reasons why a dental crown might need to be replaced. Some of them are:


A) Tooth decay has formed at the edge of the crown.

While a dental crown cannot decay the tooth on which the crown is cemented certainly can. If dental plaque is allowed to accumulate on a tooth in the region where the crown and tooth meet, a cavity can start.

While there can be a lot of variables with this type of situation, the worst-case scenario for your dental crown is that in order for your dentist to be able to get at and remove the decay the crown will need to be taken off and replaced with a new one.


B) The dental crown has become worn excessively.

Dental crowns are not necessarily significantly more resistant to wear than your own natural teeth, nor is it in your best interest that they should be. The ideal dental crown would be one made out of a material that has the same wear characteristics as tooth enamel. This way neither the dental crown nor your teeth would wear the other excessively.

Dental crowns can wear out, especially in those cases where a person has a habit of clenching and grinding their teeth. A dentist will sometimes detect a small hole on the chewing surface of a dental crown in that area where it makes contact with an opposing tooth (meaning a tooth that touches on the crown when you bite). Since the seal of the crown has now been lost your dentist will probably recommend that a new crown should be made, before that point in time when dental plaque has seeped in underneath the crown and has been able to start a cavity.


C) The dental crown has broken.

Dental crowns can break, or more precisely the porcelain component of a dental crown can fracture. Some dental crowns are made in a fashion where their full thickness is porcelain (all-ceramic dental crowns). If this is the case then if the crown breaks it will most likely have broken all of the ways through, thus compromising the seal of the crown and necessitating its replacement. Even with a less catastrophic fracture, it seems likely that the aesthetics or function of the crown could be compromised, thus providing a reason why the crown should be replaced.


D) The aesthetics of the crown has become objectionable.

Some dental crowns are replaced because, from a cosmetic standpoint, their appearance is no longer pleasing. Two situations where the cosmetic aspects of a dental crown can change with time are:


E) The dental crown’s edge has become visible and it has a grey appearance.

As time passes the gum line of a tooth on which a dental crown has been placed will sometimes recede. This is especially likely in those cases where diligent brushing and flossing have not been practised. If enough recession takes place the edge of the dental crown, which was originally tucked out of sight just under the gum line, will become visible. Many times this edge of the crown will have a grey appearance.

Inherent to porcelain-fused-to-metal dental crowns (related to their construction) is the fact that the very edge of these crowns will typically show some darkness (a hint of the grey metal that lies underneath the porcelain). If enough gum recession occurs this dark edge will become visible, thus spoiling the cosmetic appearance of the crown.

F) The colour of the dental crown no longer matches its neighbouring teeth.

Also related to the cosmetic appearance of a dental crown, there can be times when, as years have elapsed, the colour of the crown no longer closely matches the shade of its neighbouring teeth. In these cases, it is not the colour of the porcelain crown that has changed but instead, the neighbouring teeth have stained and darkened.

There can be two solutions to this situation. The dental crown can be replaced with a new one that more closely matches the current colour of its neighbouring teeth. Another solution could be to use a teeth whitening process so to attempt to return the neighbouring teeth to the colour they were when the dental crown was originally placed.


Symptoms you will feel that let you know when your Dental Crown needs to be Replaced


1. Your bite feels “off.”

When your crown is first fitted and placed, your bite should feel completely normal. If, over time, your bite starts to feel uneven, something may have occurred with your crown and it may need to be adjusted or replaced.


2. The gums around your crowned tooth are receding.

If you notice your gum tissue pulling away from the crowned tooth, it could indicate that the crown was improperly placed. It could also indicate that you have gum disease and need to seek periodontal treatment with your dentist.


3. Your crown is very old.

Crowns that are older than five years are more likely to develop problems due to natural wear and tear. It is critical to have your crowns checked twice a year to allow your dentist an opportunity to inspect your restorations and ensure everything is healthy and functioning properly.


4. You have pain in or around a crowned tooth.

While it is very rare for a metal crown to break or chip, porcelain crowns or the porcelain component of a porcelain-fused-to-metal crown can sometimes suffer surface damage due to the wear and tear of everyday use, eating or excessive force caused by bruxism. Broken or cracked crowns may expose the underlying tooth and can cause pain, swelling or tenderness.

In the case of a fractured or damaged crown, it is crucial to restore the crown’s integrity so it can continue to protect the underlying tooth. Depending on the extent of the damage, it may be easily repaired with a quick buffing, or it may require replacement.


Is your Dental Crown showing signs of Failure?


If you’d like to see your dentist but are in a fix in terms of finances, you should know that most dental insurance companies cover costs of crown replacement or repair in 5 years. So, if you have dental insurance, don’t hesitate to book an appointment with us if a crown you recently got is giving you problems. Before your dentist performs any procedures, they’ll first examine your oral cavity and determine your existing crown’s health.

Dental crowns help prevent further decay to your tooth, protect it from further damage in addition to preventing the loss of your tooth. This is not to mean that you should only see your dentist when you have a dental issue. You should visit your dentist at least twice a year for regular cleanings and check-ups. We can help you address any dental concerns you may have.
