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. Here’s a comprehensive guide to help you understand intermittent tooth pain under a crown and how to manage it.

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.

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.

oral hygiene

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.

hard food

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.

sensitive toothpaste

Use Sensitivity Toothpaste

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

monitor and report symptoms

Monitor and Report Symptoms

Keep track of when the pain occurs, how long it lasts, and any other symptoms you experience. This information can be valuable for your dentist in diagnosing the issue.

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.

When to Seek Immediate Help

While intermittent tooth pain under a crown can often be managed with a dental visit, there are situations where immediate help is necessary:

  • Severe or Persistent Pain: If the pain becomes severe or doesn't go away, it could indicate a serious infection or other issues that need urgent attention.
  • Swelling and Fever: These symptoms can indicate an abscess or serious infection that requires prompt treatment.
  • Loose Crown: If your crown becomes very loose or falls out, seek dental care immediately to protect the underlying tooth.

Conclusion

Intermittent tooth pain under a crown can be a sign of various dental issues, ranging from decay to nerve damage. Maintaining good oral hygiene and scheduling regular dental checkups are crucial for preventing and addressing these problems. If you experience tooth pain under a crown, don’t hesitate to contact your dentist. Early diagnosis and treatment can prevent more serious complications and help maintain your healthy smile.
