What You Need to Know About Dental Crown Infections

Dental crown infections can be serious, and preventing them requires proper dental crown care and maintenance. These infections have various causes, symptoms, and risks. Here’s what you need to know:


  • Ill-fitting crowns:
    A poorly fabricated tooth crown or one that doesn’t fit well can allow bacteria to gain access to the underlying tooth, leading to decay of the tooth and infection around the crown.
  • Gum infections:
    Infection of the gum tissue surrounding a dental crown can cause bleeding gums, bone loss, and tooth mobility, which can impact the crown and adjacent teeth.
  • Poor oral hygiene:
    Neglecting daily routine care, like brushing and flossing, and consuming sugary and acidic foods can contribute to a dental crown infection.


  • Tooth sensitivity and pain:
    Sensitivity and pain on the tooth with the crown is a common sign of infection.
  • Gum pain and recession:
    Pain in the gums and gum recession around the crown may indicate an infection.
  • Signs of infection:
    Swelling, redness, and foul taste can signal an underlying tooth crown infection.


  • Tooth decay and infection:
    Without proper dental hygiene and maintenance, dental decay can develop under the crown, leading to an infection. The treatment for this condition may include root canal therapy or crown replacement.
  • Damage to adjacent teeth and gum tissue:
    Without proper treatment, dental crown infection may spread to adjacent teeth and gums, complicating dental treatments and risking one’s oral health.
  • Impact on overall health:
    Chronic infections can affect your dental health and general health condition, making dental appointments and adherence to a healthy diet vital.

Recognising the Symptoms of Dental Crown Infections

Recognising the symptoms of a dental crown infection is crucial to maintaining dental hygiene and seeking the right course of treatment.

Whether you’ve just had a dental crown procedure or want to understand how to avoid having a decayed tooth underneath a crown, knowing the signs that indicate infection is vital.

  • Swelling around the tooth crown area:
    One of the common symptoms of dental crown infection is swelling around the tooth. This may or may not be accompanied by pain.
  • Increased sensitivity to temperatures:
    If the tooth under the crown becomes more sensitive to hot or cold, it might indicate inflamed nerves or a developing infection.
  • Pain and discomfort:
    Dental crown infections often present themselves with pain. It could be a dull, constant pain or sharp shooting pain, and the area around the crown may also feel sensitive when touched.
  • Bad taste or bad breath:
    Bacteria can lead to decay of the tooth underneath the crown, resulting in a bad taste or bad breath. In some cases, pus may also develop and seep into the mouth, resulting in a metallic taste.
  • Oozing pus:
    If you notice pus around the area where the crown is, it means immediate attention is needed. Dental abscesses can lead to tooth and bone resorption and have the potential to spread to nearby teeth or other areas of the body.
  • Difficulty in chewing:
    An infection under the crown can cause discomfort or difficulty chewing. When this happens, visit your dentist for proper treatment.
  • General health symptoms:
    Sometimes, severe tooth crown infection could manifest as fever or fatigue.

Causes Behind Dental Crown Infections

Dental crown infections can be perplexing, inconvenient, and, in severe cases, painful. Understanding the root causes behind these infections is key to promoting dental crown care and maintaining good dental hygiene.

Here are factors that may lead to dental crown infections:

  • Improper crown placement:
    If a crown is not fitted properly over the natural tooth, it might leave gaps where bacteria can enter, which can cause decay and infection.
  • Cracks in the crowns:
    Dental crowns have the potential to crack when subjected to high forces, such as chewing hard foods or experiencing a sudden impact. A cracked or defective crown may expose the underlying natural tooth structure, allowing the bacteria to cause tooth decay, potentially leading to infection.
  • Poor oral hygiene practices:
    Neglecting regular oral hygiene practices or using improper methods can result in dental crown infections.
  • Underlying tooth issues:
    If the tooth with the crown has underlying issues, like active decay, that were not addressed prior to crown installation, the decay can progress and cause dental crown infection.
  • Delay in treatment:
    Ignoring common signs of dental decay, like sensitivity to hot and cold or persistent pain, may lead to the development of an infection. Seeking prompt dental treatment is an essential step in dental crown care.
  • Previous dental work:
    If a dental implant treatment, root canal therapy, or dental crown procedure was not completed by an experienced dentist or the proper protocols were not followed, it may set the stage for infection later on.

Dental crown infections don’t just occur; they’re often the result of a combination of factors. Several aspects play a role, from the quality of the treatment provided to the attention given to dental hygiene and dental crown maintenance.

Recommendations for Dental Crown Infections

A dental crown infection can be concerning, but there are treatments available to address it.

Both medical interventions and home remedies exist to address the situation. These recommendations align with dental crown care principles and aid in dental crown maintenance.

Let’s explore some options:

Medical interventions

  • Consulting a health professional:
    A visit to a dentist for an infection around crown treatment is often the first step. An experienced dentist can diagnose the condition and provide the appropriate care within a reasonable time frame.
  • Dental fillings and replacements:
    Sometimes, resolving the infection might involve placing dental fillings on the underlying tooth and replacing the dental crown. This approach prevents the further progression of decay.
  • Antibiotics:
    In cases of severe infection, dentists may recommend the use of antibiotics alongside dental treatment. This aids in addressing the infection more quickly.
  • Root canal treatment:
    A root canal treatment might be necessary if the infection has reached the nerve of the tooth. An experienced dentist can assess this through oral examination, diagnostic tests and radiographs.

At-home measures for relief

  • Pain medication:
    Using over-the-counter pain relief medication can provide relief for severe pain caused by a dental crown infection. It is important to adhere to the instructions provided by your dentist when taking any medications.
  • Saltwater rinses:
    A simple yet effective method to alleviate discomfort or pain, saltwater rinse has natural anti-inflammatory properties that can bring temporary relief to patients.
  • Avoid certain foods:
    Reducing the intake of sugary, hot, or cold foods can alleviate the symptoms and help promote dental crown maintenance.
  • Maintain oral hygiene:
    Regular brushing, flossing, and following a proper dental hygiene routine can help maintain a healthy mouth.

Essential considerations

  • Follow professional advice:
    Always follow the instructions given by dental health professionals. Self-diagnosis or delaying your treatment could worsen the situation.
  • Monitor symptoms:
    Keep track of symptoms and inform your dentist if they persist beyond the expected time frame. Monitoring is part of comprehensive dental crown care.

Preventive Measures to Avoid Dental Crown Infections

Prevention is a central part of dental crown care, and there’s no overstating its importance. By adopting responsible habits and daily practices, you can minimise the risk of dental crown infection. The following preventive strategies are designed to promote good oral hygiene and extend the life of dental restorations.

Dental Hygiene Practices

  • Regular cleaning:
    Brushing and flossing at least twice daily maintains oral cleanliness. Incorporate an appropriate dental hygiene routine to keep crowns and natural teeth healthy.
  • Professional check-ups:
    Regular visits to an experienced dentist allow for early detection of dental problems, including inflamed gum tissue surrounding the crown and common infection signs. This also provides patients with the opportunity to have a dental cleaning.

Food and Lifestyle Choices

  • Avoid sticky and hard foods:
    Eating these foods might lead to crown cracks or damage. Choose foods that do not exert excessive pressure on dental crowns or require excessive chewing.
  • Limit sugary foods:
    Sugary foods increase the risk of bacterial plaque accumulation and infection around crowns. Moderation is important.
  • Avoid extremely hot and cold foods:
    Temperature sensitivity can lead to discomfort. Being mindful of food temperatures promotes comfort with your dental crown.

Consideration for Specific Crowns

  • Proper care for temporary crowns:
    Be extra cautious if you have a temporary tooth crown. Following the dentist’s recommendations is a crucial step.
  • Maintenance for root canal-treated teeth with dental crowns and dental bridges:
    Individual care practices might be required to deal with crowns in root canal-treated teeth or dental bridges. Consulting a health professional for advice on dental crown maintenance is advisable.

Dental Crown Procedures and Selection

  • Choose the right materials:
    Various materials, like metal or zirconia, offer maximum protection. Discuss the different crown materials with your dentist to know which one will suit your needs.
  • Correct installation:
    An infected crown might result from improper crown placement. Choosing a qualified dentist to provide you with quality dental crown treatment can mitigate this risk.

Additional Tips

  • Avoid tooth grinding:
    Consider wearing a night guard if you grind your teeth.
  • Educate yourself on the causes of dental crown infections:
    Knowing about the risk of bacterial plaque and improper oral hygiene and dietary habits can help make informed decisions about oral health.
  • Follow post-procedure guidelines:
    After a dental crown treatment, following post-procedure care as advised by health professionals is vital.

Choosing the Right Dental Care for Your Crowns

Choosing an experienced dental professional to perform your dental crown treatment can significantly reduce the risk of dental crown infection. Though the process may seem invasive, several thoughtful considerations can guide you towards a decision that aligns with your needs and goals.

Here’s how to approach this decision:

Evaluate experience and knowledge.

  • Ask about their experience with dental crown procedures:
    Seek dental professionals who have handled numerous dental crown restorations.
  • Ask about the dental crown infection prevention approach:
    A dental professional who emphasises dental hygiene and infection prevention practices is a valuable asset.

Consult previous clients and reviews.

  • Read client testimonials:
    Customer feedback can offer insights into the quality of dental crown care.
  • Consider recommendations from friends and family:
    Personal recommendations can often lead to finding a qualified dentist.
    Assess the approach to dental hygiene.
  • Inquire about dental hygiene practices:
    Ask about their dental hygiene and dental crown maintenance approaches to gauge if they align with their needs.
  • Look for continuous education and training:
    Dental professionals who stay abreast of the latest oral hygiene methods will likely provide top-notch care.

Discuss materials and techniques.

  • Talk about crown materials:
    Different materials, from metal to ceramic, offer different benefits. The dentist should discuss these with you.
  • Discuss dental procedures like root canal treatment or dental bridge:
    Have an open conversation about the specific procedures that may be involved, such as the root canal treatment, and what cases may require a dental bridge.

Evaluate Overall Approach

  • Visit the clinic for a first-hand view:
    A visit to the dentist can provide insight into the perspective of the dentist, their team, and the overall clinic atmosphere.
  • Assess communication and comfort:
    An experienced dentist who makes you feel comfortable and communicates clearly can make dental crown care a more pleasant experience.
  • Consider financial aspects:
    Transparent pricing and flexibility in payment for tooth crown procedures can indicate a thoughtful and patient-centric approach.

Consider Additional Factors

  • Location and accessibility:
    The clinic’s location, opening hours, and accessibility might be factors that suit your lifestyle.
  • Emergency services:
    Knowing how the clinic handles emergencies related to dental crown infections can add to your peace of mind.

The Importance of Regular Dental Check-Ups

Regular dental check-ups are essential in maintaining your dental health, including those with crowns. These visits are pivotal in dental crown care, prevention of dental crown infection, and overall dental hygiene. Here’s a concise look at why these check-ups matter:

  • Early detection of potential problems
    Regular visits to a dental professional provide them with an opportunity to catch problems like crown cracks or infected crowns during the early stages, allowing for timely intervention and reducing the risk of more severe complications.
  • Dental crown maintenance
    Caring for dental crowns requires unique considerations. Regular check-ups are important for examining and assessing the crowns, as they help to prevent complications and allow for necessary maintenance before the situation becomes more complex.
  • Emphasis on dental hygiene
    Dental hygiene is essential for overall health. Regular check-ups allow dentists to offer tailored advice on dental hygiene routine, including advice on methods to maintain natural teeth alongside dental restorations like crowns and bridges.
  • Education and personalised advice
    A dental check-up is valuable for education and receiving personalised advice on dental crown care from a health professional. This includes dietary guidelines that might affect crowns and proper cleaning techniques.
  • Monitoring overall oral health
    Regular dental visits allow for continuous assessment of oral health, including factors such as decay, tooth condition, implant status, and other important aspects of maintaining a healthy mouth. This continuous monitoring makes dental treatments, such as dental fillings or root canal procedures, remain effective as intended.
