A crown, or dental crown, is a cap placed over a damaged tooth to restore its shape, strength, and appearance. While crowns are generally durable and effective, experiencing pain when biting down can be a significant concern. Let's explore the potential reasons behind this discomfort.
What Could Be Causing the Pain?
Several factors can cause pain in a crowned tooth when biting down. Understanding these possibilities is crucial for seeking appropriate dental care.
1. Irritation or Inflammation Under the Crown:
This is a common cause. Even with meticulous crown placement, microscopic food particles, bacteria, or saliva can get trapped between the crown and the tooth. This can lead to inflammation of the underlying tooth structure (pulpitis) or gum tissue (gingivitis), causing sensitivity and pain, especially when pressure is applied during biting.
2. Cracked Tooth Under the Crown:
A pre-existing crack in the tooth that wasn't fully addressed before crown placement can worsen over time. Biting down can exacerbate the crack, leading to significant pain. This requires immediate dental attention.
3. High Crown:
If the crown is placed too high, it can interfere with your bite, putting excessive pressure on the tooth and surrounding structures. This can result in pain, discomfort, and even damage to the jaw joint (temporomandibular joint or TMJ).
4. Infection:
An infection under the crown can lead to severe pain, especially when pressure is applied. This infection could originate from a variety of sources, including pre-existing decay or trauma.
5. Gum Recession:
As gums recede, they may expose the margin of the crown, leading to sensitivity and pain when biting. This is a gradual process, but the resulting pain can be noticeable.
6. Abscess:
A severe infection that forms a pocket of pus at the root of the tooth can cause intense pain when biting down. This requires immediate professional dental intervention.
7. Sinus Infection:
While less common, a sinus infection can sometimes refer pain to the upper teeth, mimicking the feeling of a problem with a crown.
What Should I Do If My Crown Hurts When I Bite Down?
Don't ignore the pain. Contact your dentist immediately. Delaying treatment can worsen the problem and lead to more extensive and potentially costly procedures. Your dentist can:
- Examine the crown and surrounding tissues: A thorough examination will help pinpoint the cause of your pain.
- Take X-rays: X-rays can reveal hidden cracks, infections, or other underlying issues.
- Adjust the crown: If the crown is too high, it can be adjusted to restore a comfortable bite.
- Address any infection: Antibiotics or root canal treatment may be necessary to address an infection.
- Replace the crown: In some cases, the crown may need to be removed and replaced.
How Can I Prevent Crown Pain?
- Maintain excellent oral hygiene: Brush and floss regularly to prevent bacteria buildup.
- Avoid biting hard objects: This can put excessive stress on your crowns.
- See your dentist regularly for checkups: Regular checkups allow your dentist to identify and address any potential problems early on.
