Dental crowns are designed to be durable, but they aren’t meant to last forever. Most crowns last between 10 and 15 years, though some can last longer with excellent care. Still, daily wear, bite pressure, and gradual changes in your oral health can cause a crown to break down over time. If your crown is aging or you’ve begun noticing changes, it’s important to pay attention to warning signs that suggest it may need to be replaced. Acting early can help prevent discomfort or dental emergencies and keep your smile functioning at its best.
Tooth Sensitivity or Discomfort
A sudden increase in sensitivity, especially to hot, cold, or pressure, is often one of the earliest signs that something may be wrong with a crown. When a crown begins to loosen or no longer seals the underlying tooth correctly, bacteria can seep underneath, leading to decay or inflammation. This irritation can make everyday activities like chewing or drinking uncomfortable. Even if the discomfort is mild, it’s worth getting evaluated before the issue escalates.
Visible Cracks, Wear, or Damage
Crowns can chip, crack, or wear down just like natural teeth. If you notice jagged edges, fractures, or a change in the crown’s shape, it may no longer be providing full protection. Wear is especially common if you grind your teeth, chew on hard foods, or have a misaligned bite. Even small cracks can spread and eventually compromise the stability of the entire restoration. Replacing a damaged crown promptly helps shield the vulnerable tooth underneath from further harm.
A Loose or Shifting Crown
A dental crown should always feel secure. If it begins to wiggle, shift, or sit differently when you bite down, it’s a strong indication that the cement holding it in place has weakened. In some cases, underlying decay softens the tooth structure, causing the crown to lose its grip. A loose crown can fall off at any time, leaving the tooth exposed and sensitive. Having it inspected quickly can prevent an unexpected emergency visit.
Gum Recession or Dark Lines at the Margin
Changes in the gumline can affect how a crown fits. If your gums recede, the margin of the crown may become visible, creating small crevices where bacteria can accumulate. This can lead to decay or irritation around the restoration. You may also notice a thin dark line near the gumline, especially if you have a porcelain-fused-to-metal crown. While sometimes cosmetic, it can also signal that the crown is aging or deteriorating.
The Importance of Regular Dental Visits
Even if your crown feels fine, routine dental checkups are essential. Your dentist can identify early warning signs, detect decay beneath a crown, and monitor its structural integrity long before problems become noticeable. This proactive approach helps ensure your crowns last as long as possible while keeping your natural teeth healthy.
Keeping an eye on these symptoms can help you stay ahead of crown failure and protect your smile.
