If you have a crown or are thinking about getting one, you might wonder if the tooth underneath can decay. This guide shows how decay can happen, the warning signs to watch for, and how to protect your dental health long-term.
Can a tooth under a crown develop decay?
A crown protects a damaged tooth, but the natural tooth underneath remains. This means decay can still affect the tooth under a crown if bacteria reach it.
Crowns are quite strong, but the edges of the crown fit perfectly with the shape of your original tooth. If you skip regular dental care, plaque around your crown can lead to tooth decay.
Why do teeth go bad under a crown?
Teeth can go bad when bacteria enter small gaps between the crown and the tooth. If a crown fits poorly or becomes worn over time, this increases the risk of decay.
If a crown is old or compromised, it may allow bacteria to affect the underlying tooth. This can lead to decay beneath the crown if left untreated
What causes tooth decay under a crown?
Several factors cause decay under crowns. Poor oral hygiene is the most common. When plaque builds up around the edges of the crown, it can cause decay beneath the crown.
Diet also plays a role. Frequent sugar intake can increase the risk of decay. Over time, even crowned teeth can become vulnerable to decay if bacteria remain trapped.
What are the warning signs of decay under a crown?
Recognising the signs of decay early can save your tooth. Common symptoms of tooth decay include tooth sensitivity, pain, and bad breath.
Watch for a bad taste or smell, discolouration under the crown, or swelling nearby. If you notice decay or a cavity under the crown, contact your dentist immediately.
Can a crown prevent tooth decay completely?
While crowns strengthen and restore your teeth, they cannot fully stop decay. They cover most of the tooth, leaving a bit of natural tooth exposed.
Even with a crown, decay can form at the tooth-gum edges. A crown safeguards your tooth, but some risk of decay remains.
How common is decay under crowns?
Many patients ask how common decay under crowns is. It is a known issue, especially in older crown restorations.
Crowns typically last 10–15 years, and as they age, they may not seal as well. This increases the chance of decay under the crown and problems with the underlying tooth.
How can you prevent tooth decay under a crown?
Prevent decay by brushing twice daily and paying close attention to cleaning around your crown.
Seeing your dentist every six months allows early detection of problems. At Southside Dental Care, we monitor your crowns and underlying teeth to support healthy teeth and gums.
What happens if a tooth decays under a crown?
Your dentist may need to take off the crown to treat the tooth if decay forms. The type of treatment depends on the extent of the damage.
Early decay can be treated by removing it and fitting a new crown. If the nerve is affected, a root canal may be required.
What are the treatment options for a decayed tooth under a crown?
The level of decay determines your treatment. If the tooth beneath the crown remains healthy, we can repair it and fit a new crown.
Severe damage might require a tooth extraction. Dental implants can be used to fill gaps and restore proper function when teeth are missing.
When should you contact a dentist?
Contact your dentist if your crown feels loose, causes pain, or shows signs of decay.
