Understanding Dental Crown Tooth Pain: 10 Common Causes

Discovering that a dental crown doesn't guarantee freedom from tooth pain can be surprising for many. While a dental crown effectively shields a fractured tooth, it doesn't make the tooth immune to various issues. Discomfort, sensitivity, or even chronic toothaches can still arise in the vicinity of the crown. Let's delve into the reasons behind dental crown tooth pain and how to address it.

What is a Dental Crown?

A dental crown, essentially a cap, serves the purpose of covering a damaged tooth. It is securely bonded in place, encapsulating the visible portion of the tooth. These crowns play a vital role in protecting and restoring the tooth's size and shape. They are often used on either side of a missing tooth to support a bridge – a dental prosthetic that fills a gap in your mouth. These crowns can be crafted from various materials like porcelain, ceramic, or metal, depending on the specific dental needs. Choosing high-quality materials for your crown is crucial. Some individuals may be sensitive or allergic to certain materials, leading to discomfort or pain. Discuss material options with your dentist.

Your dentist might recommend a dental crown for:

  • A cracked or weakened tooth
  • Discolored or misshapen tooth
  • A severe cavity that cannot be addressed with a filling
  • A missing tooth requiring a bridge or implant

Common Causes of Dental Crown Tooth Pain

1. Tooth decay under the crown

Despite the protective cover, the tooth under the crown is still susceptible to decay. The junction between the tooth and crown can harbor tooth decay, leading to chronic pain.

2. Infection

If a root canal wasn’t performed before crown placement, the tooth retains its nerves. The crown pressing against an injured nerve can lead to infection. Old fillings under the crown may also leak bacteria, causing nerve infections.

3. Sore gums from crown procedure

Discomfort following a crown placement is normal, but it should be temporary. If the discomfort persists beyond two weeks, consulting your dentist is essential.

4. Fractured tooth or crown

A cracked crown or a fractured tooth beneath it can cause mild pain, particularly when exposed to cold, heat, or air. Prompt repair is necessary for a cracked or loose dental crown.

5. Teeth grinding

Nighttime teeth grinding, or bruxism can strain the crown, resulting in pain. Using a mouthguard can help alleviate this issue.

6. Recessed gums

Gum recession around the crowned tooth can expose roots, leading to discomfort and sensitivity. Brushing too vigorously can contribute to gum recession, making the area more prone to plaque buildup and gum dise ase.

7. Incorrect crown fit

A poorly fitting crown can cause discomfort and affect your bite or grin. Discomfort while biting down may indicate a crown that is too high on the tooth.

8. Nerve issues

If the crowned tooth still experiences nerve-related problems, such as inflammation or damage, it can result in persistent pain. Further dental evaluation may be necessary.

9. Adjacent tooth problems

Issues with teeth adjacent to the crowned tooth, such as decay or infection, can radiate pain to the crowned tooth. A comprehensive dental examination is essential to identify and address these concerns.

10. Allergic reactions

Some individuals may develop allergic reactions to the materials used in dental crowns. Allergies can manifest as pain, swelling, or discomfort in the surrounding tissues. If you suspect an allergic reaction, it's vital to communicate this to your dentist for appropriate material alternatives.

The bottom line

If you're experiencing severe or persistent tooth pain around a crowned tooth, seeking professional dental guidance is crucial. Depending on the issue, solutions may involve a root canal, crown replacement, or even tooth extraction. Don't ignore persistent discomfort, as timely intervention can prevent further complications and ensure optimal oral health. Your dentist is your ally in addressing dental crown-related concerns and maintaining a pain-free smile.
