Should Your Crowns Be Replaced?

November 28, 2023

Dental crowns are a common solution for restoring damaged or decayed teeth. They are designed to be durable and long-lasting, but like any dental restoration, they may eventually require replacement.

Knowing when your dental crowns need to be replaced is crucial to maintaining optimal oral health and avoiding potential complications. Here are some signs to watch out for that may indicate it’s time to consider replacing your dental crowns.

Visible Damage or Wear

Dental crowns are designed to withstand normal biting and chewing forces. However, over time, they may become damaged or worn. Although dental crowns are durable and can last for years, they are not immune to damage, especially from teeth grinding [1]. Inspect your dental crowns regularly for signs of cracks, chips, or fractures that could mean they need to be replaced.

Tooth Sensitivity

When used to protect an intact natural tooth, dental crowns cover the entire visible portion of a tooth, protecting it from sensitivity caused by hot or cold temperatures. If you start experiencing sensitivity in a tooth with a crown, it could be a sign that the crown is no longer protecting the tooth underneath.

This sensitivity may indicate that the underlying tooth structure is exposed or that the crown has become loose, allowing irritants to reach the affected tooth. In either case, it’s essential to have your crown evaluated to prevent tooth decay or infection underneath your restoration.

Discoloration

Dental crowns are made of materials that resemble natural tooth enamel, such as porcelain ceramic, making them less likely to stain than your natural teeth. However, loose or damaged dental crowns may begin to discolor around your gumline, especially if you have porcelain fused to metal crowns [2]. Any discoloration around your crowns is a sign they may need to be repaired or replaced.

Gum Inflammation or Recession

Healthy gums should tightly hug the base of dental crowns, allowing you to have a natural appearance. If you notice gum inflammation, swelling, or bleeding around a dental crown, it could indicate an underlying issue.

Loose or ill-fitting dental crowns can cause irritation or infection in the gum tissue. Additionally, if you notice gum recession around the crown, it may be a sign that it needs to be replaced or adjusted to prevent further problems and ensure a proper fit.

Changes in Fit or Bite

Dental crowns should fit snugly and comfortably. If you notice changes in the fit or bite of a crown, it may need to be repaired or replaced [3]. A loose or ill-fitting crown can cause discomfort and create a breeding ground for bacteria, potentially leading to decay or infection.

If you experience any changes in the way your crown feels or if it feels loose, consult your dentist.

Schedule a Check-up for Your Dental Crowns

Although these are all signs that your crowns may need to be replaced, only your dentist can identify a crown needing replacement. Regular dental check-ups and good oral hygiene practices are essential for monitoring the health of your dental restorations. If you notice any of the above signs, schedule an appointment with your dentist, as early intervention can potentially save your crown and help you maintain a healthy smile!
