Dental crowns are caps placed over teeth that have been damaged or weakened. Crowns help restore the original shape, strength, and function of that tooth. Over a period of years, crowns can wear out, crack, or be damaged and/or become loose. Understanding the signs of a failed dental crown helps you protect your tooth and maintain proper oral health. This article will explain how to know if you have a dental crown that needs to be replaced and when you should talk to your dentist in St. Albert.
What is a Dental Crown?
A dental crown is a custom-made cap that covers and protects a damaged tooth. A dentist will recommend a dental crown in St. Albert for teeth that are weakened, broken, or require a large filling. Crowns can be made of metal, porcelain, ceramic, or a combination of materials. Crowns are manufactured with the same shape and appearance as a natural tooth, which allows you to chew and speak normally.
Crowns are generally a strong prosthetic. However, they can become damaged over time from normal wear, an injury, or decay underneath the crown. Knowing the signs of a failing dental crown helps you avoid serious dental problems.
Signs of a Failing Dental Crown
Here is a list of common signs that can indicate you may need a dental crown replacement
1. Pain or Sensitivity
If you feel pain when biting, chewing, or eating hot or cold foods, it may mean the crown is loose or the tooth underneath is decayed. Sometimes the cement holding the crown weakens, letting bacteria enter. If ignored, this can lead to infections or abscesses.
2. Visible Cracks or Chips
Sometimes, a cracked or chipped crown puts the tooth’s structure at risk. Small cracks may not cause pain at the moment, but they can get worse over time. A broken crown can also trap food and bacteria that can lead to decay.
3. Looseness or Movement
Crowns are made to fit securely and snugly in place. Thus, if it feels either too loose or moves whenever you bite, it would likely need to be replaced. Loose crowns would eventually end up falling off and damaging the tooth below it.
4. Dark Lines at the Gum Line
If any dark lines can be observed around the gum lines of your tooth with the crown, then that most likely means the crown margin is either worn down or under decay. This is common with older crowns, especially those with metal bases.
5. Gum Irritation
Swollen gums or inflamed tissue near the crown can also be a warning sign of gum disease or crown failure. Irritation can simply occur when bacteria build up underneath a damaged or loosened crown.
6. Bad Taste or Bad Breath
A bad taste you cannot get rid of or persistent bad breath could mean that there is decay or infection underneath your crown. Ignoring it can lead to a more complicated dental issue in the future.
When to Replace Old Dental Crowns
Dental crowns can last anywhere from 5 – 15 years, depending on the material used as well as your oral hygiene habits. You should be visiting a dentist regularly to monitor the longevity of your crowns. If you are observing any of the signs above, it may be time to replace it.
Here is an easy table showing common signs of a failing dental crown.
| Sign of Failing Crown | Possible Cause | Action Needed |
| Pain or sensitivity | Decay under the crown or loose cement | Visit the dentist immediately |
| Visible cracks/chips | Trauma or wear | Crown replacement recommended |
| Loose crown | Worn cement or damaged crown | See a dentist for re-cementing or replacement |
| Dark lines at the gum | Decay or old crown material | Dental evaluation needed |
| Gum irritation | Infection or poor fit | Professional cleaning and crown check |
| Bad taste or breath | Infection or decay | Urgent dental visit |
What Happens If I Ignore a Damaged Crown?
You may be asking yourself why you should be concerned about minor damage to your crown. The failing crown will most likely cause some decay to the natural tooth below and could lead to infection. At this point, the treatment could mean a root canal or even extraction. Also, note that fabricating a crown would be so much easier if the tooth were not damaged. Early treatment will save time, money, and pain.
How to Know If a Dental Crown Needs to Be Replaced
To determine if a crown needs to be replaced, watch for the signs above and schedule return visits to your dentist. A dentist near you will be able to assess the crown, looking for decay, cracks, or even loosening. Together, you can identify the best solution. Occasionally, your crowns will need to be replaced when the tooth, crown, and materials appear to be without visible problems, especially in the cases of crowns that are older and/or the material is prone to issues.
