Experiencing pain when chewing after a dental crown procedure is a common concern. While a dental crown restores a damaged tooth and protects it, some discomfort or sensitivity can occur as the mouth adjusts. Understanding the reasons behind this pain helps determine if it is normal healing or requires dental attention.
Expected Post-Crown Sensitivity
Some temporary tooth sensitivity is common after dental crown placement. This sensitivity often arises because the tooth’s outer enamel layer is reduced during preparation, which can irritate the underlying nerve. The tooth and surrounding tissues need time to adjust to the new crown, and this initial discomfort is a normal part of healing.
This sensitivity typically manifests as a reaction to temperature changes, such as hot or cold foods and drinks, or to mechanical pressure from biting. In most cases, these symptoms are mild and should gradually subside within a few days to a couple of weeks. If sensitivity persists or worsens, it may indicate a more significant issue.
Underlying Causes of Chewing Pain
When chewing pain persists or becomes severe after a crown, it often points to an underlying issue requiring dental evaluation. One common cause is a “high spot” on the crown, meaning it is slightly taller than surrounding teeth. This leads to excessive pressure on the crowned tooth when biting down, causing discomfort.
Inflammation of the dental pulp, known as pulpitis, can also cause pain. This inflammation can be reversible, often due to tooth preparation trauma, or irreversible if nerve damage is extensive. While reversible pulpitis might resolve on its own, irreversible pulpitis typically requires a root canal to remove the infected pulp.
New or worsened tooth decay under or around the crown is another frequent culprit. Decay can occur if the crown does not seal properly, allowing bacteria to penetrate the tooth, or if pre-existing decay was not fully addressed. This can lead to sensitivity, a dull ache, or sharp pain when chewing.
A cracked tooth, present before or after placement, can cause sharp pain when biting or releasing pressure. An ill-fitting crown that does not properly seal the tooth can allow bacteria to enter, potentially leading to decay or infection. Such a crown might also feel loose or cause gum irritation. Finally, referred pain from another tooth or area can sometimes be perceived in the crowned tooth.
When to Consult a Dentist
It is important to recognize when chewing pain after a crown goes beyond normal, temporary sensitivity and warrants professional dental attention. Consult a dentist if the pain worsens, becomes severe, or is throbbing. Severe pain interfering with eating, sleeping, or daily activities signals a needed evaluation.
Other symptoms indicating a potential problem include pain with swelling, fever, or a persistent bad taste. If you experience sharp pain when biting down or releasing pressure, or if sensitivity to hot or cold lingers, seek dental advice. Timely intervention can prevent minor issues from escalating.
Home Care and Management
For mild discomfort after a crown, several home care measures can provide temporary relief while awaiting a dental appointment or during normal healing. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain and inflammation. Rinsing with warm salt water can also reduce inflammation and soothe irritated gums.
Adjusting your diet by avoiding chewing on the affected side and consuming softer foods can minimize discomfort. If sensitivity to temperature is present, avoid very hot or cold foods and drinks. Using a desensitizing toothpaste, containing ingredients like potassium nitrate or fluoride, can help block pain signals. Maintaining good oral hygiene, including gentle brushing and careful flossing, is also important to prevent further irritation. These measures are temporary and not a substitute for professional diagnosis and treatment if pain is persistent or severe.
