Tooth Pain Under a Crown Comes and Goes

Q: What Causes Tooth Pain Under a Crown?

Decay Under the Crown Cause: Even with a crown, the underlying tooth can still develop decay. Bacteria can seep under the crown, leading to cavities and subsequent pain. Symptoms: Sensitivity to hot, cold, or sweet foods, and persistent discomfort in the affected area. Why It Comes and Goes: Decay-related pain can fluctuate with exposure to certain foods or temperatures. Loose Crown Cause: Over time, the cement holding your crown in place can weaken, causing the crown to become loose. Symptoms: Pain when biting down, a sensation that the crown is moving, and possible food debris trapped under the crown. Why It Comes and Goes: The pain may only occur when pressure is applied, such as when eating or biting. Gum Recession Cause: Receding gums can expose the edge of the crown and the tooth root, making them sensitive to temperature changes and pressure. Symptoms: Sensitivity to temperature changes and pain near the gum line around the crown. Why It Comes and Goes: The pain might be triggered by hot or cold drinks and might not be constant. Nerve Damage or Infection Cause: If the tooth pulp under the crown becomes infected or inflamed, it can cause intermittent pain. This can occur if the crown was placed over a tooth with pre-existing nerve damage or if an infection develops after the crown is placed. Symptoms: Throbbing pain, swelling, and sometimes a bad taste in the mouth if an abscess forms. Why It Comes and Goes: Pain from nerve issues can be sporadic, often intensifying at night or when chewing. Bite Issues Cause: If the crown is not properly aligned with your bite, it can cause uneven pressure and pain when chewing. Symptoms: Pain when chewing, jaw discomfort, and potential wear on adjacent teeth. Why It Comes and Goes: Pain typically arises during chewing or biting and subsides when not eating.

Q: Treatment Options for Tooth Pain Under a Crown

Crown Adjustment or Replacement: If your crown is loose or not fitting properly, your dentist may need to adjust or replace it to ensure a proper fit and alleviate pain. Decay Treatment: If decay is present under the crown, your dentist will need to remove the crown, clean out the decay, and possibly perform a filling or root canal before placing a new crown. Gum Treatment: If gum disease or recession is the cause, your dentist may recommend treatments to improve your gum health, such as deep cleaning, scaling, and root planing. Root Canal Therapy: If the tooth pulp is infected or damaged, a root canal may be necessary to remove the infected tissue and relieve pain. Afterward, the crown may be re-cemented or replaced. Bite Adjustment: If bite issues are causing pain, your dentist may need to adjust the crown or other teeth to ensure a proper and comfortable bite.

Experiencing tooth pain under a crown can be concerning, especially when the pain comes and goes. Understanding the potential causes and knowing what steps to take can help you address this issue effectively.

How to Address Tooth Pain Under a Crown

Schedule a Dental Appointment

If you experience intermittent pain under your crown, it's essential to see your dentist. They can examine the crown, take X-rays, and determine the cause of the pain.

Good Oral Hygiene

Maintain excellent oral hygiene by brushing twice a day, flossing daily, and using an antibacterial mouthwash. This can help prevent decay and gum disease, which can contribute to pain under a crown.

Avoid Hard Foods

Avoid chewing on hard foods like ice, hard candies, and nuts, which can cause damage to the crown or underlying tooth structure.

Use Sensitivity Toothpaste

If gum recession is causing sensitivity, using a toothpaste designed for sensitive teeth can help alleviate discomfort.
