Tooth Decay Under a Crown: Pictures, Causes, and Treatment
Dental crowns are excellent restorations for protecting severely damaged teeth. However, even with a crown in place, decay can still occur underneath. This often goes unnoticed until significant problems arise. This comprehensive guide explores tooth decay under a crown, including visual examples (though we can't display actual pictures here), causes, symptoms, and treatment options. Understanding this issue is crucial for maintaining long-term oral health.
What Does Tooth Decay Under a Crown Look Like?
Unfortunately, I can't display images directly. However, imagine this: decay under a crown is invisible from the outside, hidden beneath the porcelain or metal cap. X-rays are the primary diagnostic tool for detecting this type of decay. Radiographs will reveal dark areas under the crown indicating the presence of decay. Clinically, your dentist might notice discoloration or sensitivity in the surrounding gum tissue, which may be an indirect sign.
How Can I Tell If I Have Decay Under My Crown?
Symptoms of decay under a crown can be subtle:
- Persistent toothache: This pain might be sharp, dull, or throbbing, and could worsen when chewing or biting.
- Sensitivity to hot and cold: An increased sensitivity to temperature changes is a common sign of decay.
- Discoloration of the gums: The gums around the affected tooth may appear darker or inflamed.
- Bad taste or odor: Decay can cause a persistent bad taste or unpleasant odor in the mouth.
- Loose crown: In advanced cases, the crown may become loose due to the underlying decay weakening the tooth structure.
If you experience any of these symptoms, it's crucial to consult your dentist immediately.
What Causes Tooth Decay Under a Crown?
Several factors can contribute to decay developing under a crown:
- Inadequate preparation before crown placement: If the tooth wasn't properly cleaned and prepared before the crown was cemented, bacteria can remain, leading to decay.
- Poor oral hygiene: Failure to maintain a diligent oral hygiene routine (brushing, flossing, and regular dental checkups) creates an environment conducive to bacterial growth, even under a crown.
- Leaking crown: Over time, the cement holding the crown in place may deteriorate, allowing bacteria and food particles to seep underneath.
- Existing decay before crown placement: If decay was present before the crown was placed and not completely removed, it can continue to progress under the crown.
- Pre-existing cracks or fractures in the tooth: These can provide entry points for bacteria.
Can Decay Under a Crown Be Treated?
Yes, decay under a crown is treatable. Treatment typically involves:
- Removing the crown: The dentist will carefully remove the crown to access the decayed area.
- Removing the decay: The decayed tooth structure will be carefully removed using dental drills.
- Restoring the tooth: The tooth will be cleaned and restored using a filling material, or in severe cases, may require a root canal.
- Replacing the crown: Once the decay has been removed and the tooth restored, a new crown will be placed.
Early detection is key to minimizing the extent of treatment required.
How Can I Prevent Decay Under My Crown?
Prevention is always better than cure. To minimize the risk of decay under a crown:
- Practice impeccable oral hygiene: Brush and floss thoroughly twice daily.
- Use fluoride toothpaste: Fluoride helps strengthen tooth enamel and prevent decay.
- Avoid sugary and acidic foods and drinks: These contribute to bacterial growth.
- Visit your dentist regularly: Schedule regular checkups and cleanings to detect and address any issues early.
Does Decay Under a Crown Always Require a Root Canal?
Not necessarily. The need for a root canal depends on the extent of the decay. If the decay has reached the pulp (the nerve of the tooth), a root canal will be necessary to remove the infected pulp and prevent further infection. However, if the decay is confined to the outer layers of the tooth, a filling and crown replacement might suffice.

Regular dental checkups are crucial for maintaining optimal oral health, especially for individuals with dental crowns.
