Getting a dental crown is a common procedure to restore a damaged or decayed tooth. While crowns are generally effective, some patients experience tooth sensitivity afterward. This sensitivity can range from mild discomfort to significant pain, impacting your ability to enjoy hot, cold, sweet, or even acidic foods and drinks. Understanding the causes, treatment options, and preventive measures is crucial for managing this common post-crown complication.
Why Does My Tooth Hurt After Getting a Crown?
Several factors can contribute to tooth sensitivity after receiving a crown. The most common reasons include:
-
Irritation to the dentin: The dentin, the layer beneath the enamel, contains tiny tubules that lead to the tooth's nerve. During crown preparation, these tubules can become exposed or irritated, leading to increased sensitivity. The cement used to attach the crown might also irritate the dentin.
-
Cement residue: Excess cement left behind during the crown placement can irritate the gum tissue and the tooth, causing sensitivity.
-
High bite: If your bite is too high after the crown is placed, it can put excessive pressure on the tooth, leading to sensitivity and pain.
-
Gum recession: Gum recession, exposing more of the tooth's root, can increase sensitivity as the root dentin is less protected than the enamel. This can be unrelated to the crown placement but exacerbated by it.
-
Cracked tooth: In some cases, the underlying tooth might have a crack or fracture that was not detected before the crown was placed. The crown might not fully address the underlying issue, leading to continued or increased sensitivity.
-
Pulpitis (inflammation of the tooth pulp): While less common, pre-existing inflammation of the tooth's pulp (the inner part containing nerves and blood vessels) might worsen after crown placement. This requires immediate professional attention.
How Long Does Tooth Sensitivity After a Crown Last?
The duration of tooth sensitivity after a crown varies greatly depending on the cause and individual responses. For many, the sensitivity is mild and resolves within a few days to a few weeks. However, persistent or severe sensitivity could indicate a more significant underlying problem. If the sensitivity persists for several weeks or worsens, it's crucial to seek professional dental advice.
What Can I Do to Relieve Tooth Sensitivity After a Crown?
Managing tooth sensitivity at home can help alleviate discomfort while you wait for professional dental assessment. Some effective strategies include:
-
Using desensitizing toothpaste: These toothpastes contain ingredients like potassium nitrate or strontium chloride that help block the tubules in the dentin, reducing sensitivity.
-
Avoiding irritating foods and drinks: Temporarily abstaining from extremely hot, cold, sweet, or acidic foods and drinks can minimize discomfort.
-
Using a soft-bristled toothbrush: Aggressive brushing can further irritate sensitive teeth. Using a soft-bristled brush with gentle brushing techniques is essential.
-
Rinsing with salt water: A warm salt water rinse can help soothe irritated gums.
What if My Tooth Sensitivity After a Crown Doesn't Go Away?
If home remedies fail to alleviate the sensitivity, or if the sensitivity worsens or becomes unbearable, scheduling a follow-up appointment with your dentist is crucial. They can:
-
Evaluate the crown: The dentist will examine the crown placement to ensure there is no excess cement or other issues contributing to the sensitivity.
-
Adjust the bite: If the bite is too high, adjustments can be made to alleviate pressure on the affected tooth.
-
Treat underlying issues: If a cracked tooth or pulpitis is suspected, appropriate treatment will be provided.
-
Recommend additional treatment: Depending on the cause, your dentist might recommend other treatments like fluoride treatments or a dental bonding procedure to further seal the dentin tubules.
Can Tooth Sensitivity After a Crown Be Prevented?
While some sensitivity is difficult to prevent entirely, you can take steps to minimize the risk:
-
Thorough initial examination: Ensure your dentist performs a comprehensive examination before crown placement, identifying any potential underlying issues.
-
Proper crown preparation: A skilled dentist will carefully prepare the tooth for the crown, minimizing damage to the dentin.
-
Careful cement application: The dentist should meticulously remove any excess cement after crown placement.
-
Regular dental check-ups: Maintaining regular dental visits helps detect and address any dental problems early on, reducing the risk of complications.
Remember, post-crown tooth sensitivity is a relatively common experience. While it often resolves on its own, persistent or severe sensitivity demands professional evaluation and treatment. By understanding the causes and taking appropriate measures, you can effectively manage the discomfort and maintain optimal oral health.
