What Causes Pain in a Crowned Tooth? + Treatment Methods

Why Does a Crowned Tooth Hurt?

 This is a question that crosses many people’s minds days, months, or even years after getting a dental crown. The cause of pain in a crowned tooth can vary—from a crown that's too high to hidden infections or decay underneath it.

In the following sections, we’ll take a close look at these causes and also present some effective solutions for reducing the pain. If you're looking for remedies that don’t require an immediate visit to the dentist, several home treatments for crowned tooth pain are also introduced, which can help you temporarily manage the discomfort until you see a professional.

 

10 Common Causes of Pain in a Crowned Tooth

 While dental crowns are an effective solution for restoring the function and appearance of teeth, in some cases, patients may experience issues like pain and sensitivity after treatment. Pain in a crowned tooth is not always a sign of a serious issue, but it should not be ignored. Several factors could be responsible for this discomfort, which we will explore in detail below:

1. Pain After Tooth Shaping for Crown Placement

 One of the most common causes of pain in a crowned tooth is the sensitivity that occurs after the enamel has been trimmed. When a layer of enamel is removed to prepare the tooth for a crown, the underlying dentin—containing sensitive nerve tubules—becomes exposed to external stimuli. This may lead to temporary pain or sensitivity to hot and cold temperatures.

 

2. Improper Bonding and Bacterial Infiltration

 If the crown is not properly bonded to the tooth surface, tiny gaps can remain between the crown and the tooth, allowing bacteria to penetrate. This can result in sensitivity, pain in the crowned tooth, and even recurrent decay or pulp infection.

 

3. Nerve Irritation During Preparation

In some cases, the process of preparing the tooth for a crown may place pressure on the tooth’s root or nerve, leading to irritation or inflammation. This can cause temporary or sometimes long-lasting pain, and may eventually require more advanced treatment like root canal therapy if left untreated.

 

4. Crown Height and Chewing Pain

 One of the most important causes of pain when chewing is an overly high crown. This issue typically becomes noticeable a few days after placement. In such cases, when chewing, the crown puts excessive pressure on the opposing tooth. This misaligned contact creates abnormal force on the crowned tooth and can lead to significant discomfort or pain.

 

5. Preexisting Dental Issues

 If the tooth had prior issues such as decay, cracks, or similar conditions before getting the crown, the likelihood of pain and sensitivity afterward increases. A thorough examination before the crown procedure is essential to prevent intensified discomfort afterward.

 

6. Gum Inflammation and Irritation

Sharp or poorly fitted crown edges can irritate the gums, leading to pain, swelling, and inflammation. Additionally, poor oral hygiene may result in plaque buildup and gum disease, which can also be a cause of crowned tooth pain.

 

7. Nighttime Teeth Grinding (Bruxism)

 Teeth grinding is a harmful habit that some individuals may experience. This condition can put excessive pressure on the crown and result in pain in the crowned tooth.

 

8. Crown Fracture or Damage

 Although crowns are designed to last for years, they may crack or break under excessive pressure, such as grinding or chewing hard objects. This can lead to pain or heightened sensitivity.

 

9. Allergic Reactions

 Although rare, some individuals may experience allergic reactions to the crown materials or dental adhesives used, resulting in discomfort or pain.

 

10. Infection or Decay Under the Crown

 Pain beneath a crowned tooth is often due to untreated infection or decay under the crown. If root canal treatment was not properly performed before placing the crown, residual infection may cause pain, inflammation, and sensitivity. In such cases, it’s crucial to visit a dentist promptly for root canal retreatment and crown replacement to prevent the infection from spreading.

In conclusion, if your crowned tooth is hurting or extremely sensitive, you should definitely consult your dentist. Early diagnosis and intervention can help prevent more severe complications and extend the life of your crown.

 

 

What Causes Pain in a Crowned Tooth Months After Placement?

 Pain in a crowned tooth several months after placement may be due to issues such as misaligned bite, decay under the crown, or bacterial infiltration around the crown. Structural problems like improper fit or the use of low-quality materials can also contribute to the pain.

What Causes Pain in a Crowned Tooth Years Later?

 Sometimes, a person may experience pain years after getting a dental crown. In such cases, identifying the cause of pain in a crowned tooth after several years is important, as it could indicate serious issues within the inner tooth structure or the surrounding gum tissue.

• If the adhesive or cement used for crown placement was of poor quality or improperly applied, the crown may loosen over time, creating a gap. This space becomes a breeding ground for bacteria and can lead to infection, decay, and pain.
  
  
• One of the most common causes of crowned tooth pain years later is decay underneath the crown. This usually starts at the junction between the natural tooth and the crown and gradually extends to the dentin or even the pulp. If the pulp or nerve becomes irritated, severe pain can occur.
  
  
• Another factor contributing to delayed pain is increased tooth sensitivity. If the root canal treatment was not thoroughly and correctly performed before crown placement, the tooth may react to cold or heat, causing discomfort. In such cases, the pain is related to unresolved issues in the root or pulp of the tooth.
  
  

 

Common Causes of Gum Pain Around a Crowned Tooth and How to Prevent It

 After crown placement, some individuals may experience discomfort or inflammation in the gum area. This is often temporary but can sometimes signal an underlying problem. Below are the main causes of gum pain around a crowned tooth:

 

1. Crown Edge Irritation

If the crown's edges are not properly designed or smoothed, they may rub against or press on the gum tissue. This constant contact can lead to inflammation, sensitivity, and ultimately, gum pain.

 

2. Residual Dental Cement

 In some cases, small particles of cement used to fix the crown may remain near the gum. These foreign materials can irritate the gum tissue and cause pain around the crowned tooth.

 

3. Allergic Reaction

 Though rare, some individuals may have allergies to the metal or composite materials used in the crown or even the dental cement. These reactions usually manifest as gum inflammation, burning sensations, and pain.

 

4. Gum Infection

Inadequate oral hygiene can allow plaque and bacteria to easily accumulate around the crown, potentially leading to gum inflammation or periodontal disease. Gum pain in these cases may be accompanied by swelling, bleeding, or even bad breath.

In any case, if you experience gum discomfort after crown placement, it’s strongly advised to consult your dentist as soon as possible. A thorough examination can help prevent serious complications down the road. Regular brushing, flossing, and dental check-ups play a key role in preventing these issues.

 

 

Effective Solutions for Treating Gum Inflammation After Crown Placement

 If you experience gum inflammation and pain after receiving a crown, don't worry—this issue is treatable. Depending on the severity of the inflammation, your dentist or periodontist may recommend various treatments. Below are the most effective methods for treating gum inflammation after a dental crown:

 

Improving Oral Hygiene

 The most fundamental step in reducing gum inflammation is maintaining proper oral hygiene. Brushing at least twice a day with a soft-bristled toothbrush, regular flossing to clean between the teeth, and using an antibacterial mouthwash can reduce plaque and bacteria buildup and speed up the healing process.

In fact, improving oral hygiene is also considered the first step in treating pain in a crowned tooth.

 

Professional Dental and Gum Cleaning

 If the gum inflammation is more advanced, your dentist may recommend professional dental cleaning and deep gum scaling. This procedure removes plaque and hardened deposits below the gumline and helps repair damaged tissue.

 

Prescribing Anti-Inflammatory or Antibiotic Medications

 In cases where inflammation is associated with bacterial infection, antimicrobial mouth rinses or topical antibiotics may be prescribed to control the infection. It’s important to note that using medication without a prescription can be dangerous, so avoid self-medicating.

Although gum irritation may be one of the causes of crowned tooth pain, with timely action and professional supervision, this type of discomfort can be effectively managed and treated.

 

 

How to Tell If a Crowned Tooth Is Infected

 Recognizing the signs of infection in a crowned tooth and seeking prompt dental care is essential. Sometimes, an infection beneath the crown may go unnoticed, but the body often sends warning signals that should not be ignored. Here are key symptoms to watch for:

1. Unusual Redness or Swelling in the Gums
    If the gums around the crowned tooth appear abnormally red or swollen, it may indicate an underlying infection.
   
   
2. Persistent, Localized, or Throbbing Pain
    One of the most common signs of infection is continuous or throbbing pain in the area of the crown.
   
   
3. Warm Sensation or Inflammation Without External Cause
    A feeling of warmth or inflammation around the crowned tooth—even without eating hot food—can be an early sign of infection.
   
   
4. Yellow or Green Discharge Around the Crown
    Any pus-like discharge near the crown is a clear indication of an active infection.
   
   
5. Bad Breath That Doesn’t Go Away
    If bad breath persists despite brushing and using mouthwash, it could be a sign of an infection.
   
   
6. Noticeable Swelling in the Area or Jaw
    Visible swelling around the crowned tooth—or even extending into the jaw—can suggest that the infection is spreading to surrounding tissues.

 

 

Medication for Crowned Tooth Pain

 Antibiotics such as penicillin, metronidazole, or clindamycin help reduce inflammation and eliminate the bacteria causing the infection. However, alongside medical treatment, some home remedies can also help alleviate symptoms. Below are the most effective ones.

 

Home Remedies for Pain in a Crowned Tooth

Sometimes, mild infections may develop under a dental crown due to bacterial intrusion. If the infection is at an early and superficial stage, it can often be controlled with medications prescribed by a dentist. However, several home remedies may also be helpful. These include:

 

Cold Compress (Ice)

 If your crowned tooth suddenly starts hurting and there’s swelling, applying ice is one of the best options. Place an ice pack or a cloth-wrapped bag of ice on the cheek near the affected area for 15 to 20 minutes. This numbs the surrounding nerves and helps reduce swelling.

 

Warm Towel

 When the pain is due to muscle inflammation around the jaw or nerve pressure, placing a warm towel on the face can provide relief. Heat helps increase blood circulation, relax jaw muscles, and reduce pain.

 

Clove Oil

 One of the most well-known natural remedies for crowned tooth pain is clove oil. It contains eugenol, which has numbing and anti-inflammatory properties. Simply apply a drop to a cotton ball and place it on the painful area for relief.

 

Salt Water Rinse

 Salt water is one of the simplest natural ways to reduce inflammation and bacteria in the mouth. Rinsing for 30 seconds can help ease crowned tooth pain and prevent the infection from worsening.

 

Garlic

This powerful plant contains strong antibacterial compounds. Crushing a clove of garlic and mixing it with a bit of salt, then placing it on the painful area, may reduce discomfort and stop bacterial growth.

 

Thyme Oil

 Thyme oil can also be used to relieve crowned tooth pain. It contains thymol, which has disinfectant properties and can help reduce inflammation and discomfort.

 

Turmeric

Thanks to its antibacterial and analgesic properties, turmeric can serve as a useful home remedy for infections under a crown. Mix one spoon of turmeric with a bit of water and apply it to the infected area. This can be repeated several times a day.

 

Ginger

Ginger contains glycerol, which helps combat harmful bacteria. You can crush ginger into a paste and apply it to the affected area, or chew a piece to release its antibacterial properties. Ginger tea also works well as a complementary treatment.

Although home remedies for crowned tooth pain are temporary, they can be a good emergency solution until you can see a dentist.

 

 

Is Gum Inflammation After a Dental Crown Dangerous?

One of the most common concerns among dental patients is pain in a crowned tooth and gum inflammation following the procedure. If gum inflammation (such as gingivitis) is not treated promptly, it can progress into a more serious condition called periodontitis.

 Periodontitis may lead to jawbone loss and, eventually, tooth loss. That’s why it is crucial to visit your dentist as soon as possible and receive professional care to control the inflammation and prevent the progression of gum disease.

 

Do Dental Crowns Put Pressure on the Gums?

 Normally, a dental crown should not put pressure on the gums. These crowns are placed over the tooth and, if properly designed and fitted, they align well with the gumline. However, if the edges of the crown are not properly contoured, or if there are issues with bite alignment (how the teeth come together), the crown may irritate the gums and cause inflammation.

For this reason, the dentist’s skill in placing the crown accurately and attending to technical details plays a key role in preventing post-crown gum pain or issues.

 

When Should You See a Dentist for Pain in a Crowned Tooth?

If you feel pain in a root canal-treated, crowned tooth, some discomfort in the first few days after placement is completely normal and usually subsides on its own within 3 days.
 However, if the pain persists longer than that or becomes more intense, it’s important to consult your dentist.

 Additionally, if pain occurs months or even years after crown placement, it could indicate a more serious problem such as decay under the crown, infection, or issues with the tooth’s nerve.

In such cases, prompt consultation with a dental specialist is essential.
 Chronic or persistent pain with no clear cause also requires thorough examination and professional treatment to prevent further damage.

Conclusion: Crowned Tooth Pain and Pain Relief Methods

In conclusion, pain in a crowned tooth is a common yet concerning issue that should not be overlooked. Sometimes, the cause of crowned tooth pain is an underlying problem such as decay or infection, which can worsen over time. In such cases, home remedies for crowned tooth pain may provide only temporary relief and are not a substitute for visiting a dentist.
