can a tooth crown get infected

Dental crowns are a cornerstone of modern restorative dentistry, offering a durable solution for damaged or weakened teeth. However, despite their protective design, complications can arise beneath a crown, particularly infections. If you’ve ever wondered, can a tooth crown get infected?, the answer is yes, though it’s not the crown itself but the underlying tooth or surrounding gum tissue that may become compromised. This comprehensive guide delves into the causes, symptoms, prevention strategies, and treatment options for tooth crown infections.

What Are the Causes of Infections Under a Dental Crown?

Infections under a dental crown typically result from several preventable or unforeseen factors:

• Poor Oral Hygiene: Neglecting daily brushing and flossing can lead to bacterial accumulation around the crown, seeping into small crevices and attacking the underlying tooth.
• Ill-Fitting Crowns: Crowns that don’t fit snugly against the tooth can create spaces where food particles and bacteria collect, increasing the risk of decay and infection.
• Pre-Existing Decay: If a tooth wasn’t properly treated for decay or damage before the crown was placed, residual bacteria can continue to thrive beneath the crown.
• Root Canal Failure: If a tooth required a root canal before crowning, incomplete removal of infected pulp can result in persistent infection.
• Crown Damage: Chips, cracks, or wear in the crown can expose the tooth underneath, allowing bacteria to infiltrate.

What Are the Symptoms of an Infected Tooth Crown?

Recognising the signs of infection is crucial to seeking timely treatment. Symptoms of an infected crown include:

• Persistent Pain: Sharp or throbbing pain, especially during chewing or biting.
• Gum Inflammation: Swollen, red, or tender gums surrounding the crowned tooth.
• Sensitivity: Heightened sensitivity to hot, cold, or sweet foods and beverages.
• Bad Breath or Foul Taste: Bacterial infections often result in unpleasant odours or tastes in the mouth.
• Discharge or Pus: In severe cases, pus may be visible near the gum line.
• Fever and Fatigue: Advanced infections can lead to systemic symptoms such as fever or a general feeling of unwellness.

What Are the Risks of Leaving an Infected Crown Untreated?

An untreated infection under a crown can lead to:

• Spread of Infection: Bacteria can travel to adjacent teeth, gums, and even the jawbone.
• Dental Abscess: Pockets of pus may form, requiring urgent care.
• Tooth Loss: Severe infection can compromise the integrity of the tooth, necessitating extraction.
• Systemic Health Issues: Oral infections can enter the bloodstream, potentially leading to serious health problems, including endocarditis.

How Can You Prevent Infections Under a Crown?

Prevention is the best approach to avoiding infections under a crown. Simple yet effective habits include:

• Maintain Proper Oral Hygiene:
  • Brush your teeth at least twice a day with fluoride toothpaste.
  • Floss daily to remove debris and plaque from between teeth and around the crown.
  • Use an antibacterial mouthwash to minimise bacteria in the mouth.
• Schedule Regular Dental Visits:
  • Professional cleanings and check-ups can identify potential issues before they escalate.
• Avoid Hard Foods:
  • Hard or sticky foods can crack or dislodge crowns, increasing infection risks.
• Address Gum Health:
  • Treat gum disease promptly, as it can weaken the tissues supporting the crown.

What Are the Treatment Options for an Infected Crown?

If a crown becomes infected, prompt treatment is essential. Here’s what you can expect:

1. Diagnosis:
   Dentists will perform a clinical examination, supported by X-rays, to pinpoint the source of the infection.
2. Cleaning and Debridement:
   The area around the crown may need thorough cleaning to remove debris and plaque.
3. Antibiotics:
   For bacterial infections, antibiotics may be prescribed to manage swelling and control the spread of bacteria.
4. Root Canal Therapy:
   If the infection has reached the tooth pulp, a root canal procedure may be required to remove the infected tissue.
5. Crown Removal and Replacement:
   Damaged or poorly fitted crowns may need to be removed and replaced to ensure proper protection and functionality.
6. Surgical Intervention:
   For severe cases, procedures like an apicoectomy (removal of the tooth root tip) may be necessary to eradicate the infection.

How Do Healthy and Infected Crowns Differ?

The table below illustrates the key differences between a healthy crown and one affected by infection:

Attribute	Healthy Crown	Infected Crown
Pain	No pain or discomfort	Persistent or sharp pain
Gum Appearance	Pink and firm	Red, swollen, or tender
Sensitivity	Minimal	Sensitivity to heat, cold, or pressure
Odour/Taste	Neutral	Foul taste or bad breath
Swelling or Discharge	None	Possible pus discharge

 

What Steps Are Involved in Treating an Infected Crown?

The treatment process can be broken down as follows:

Step	Description	Duration
Diagnosis	Dental exam and X-ray to locate the infection	1 visit
Cleaning	Removing plaque and debris around the crown	1 visit
Antibiotic Prescription	To control bacterial infection	5–7 days
Root Canal Therapy	Treating the infected pulp if necessary	1–2 visits
Crown Replacement	Replacing damaged or ill-fitting crowns	1–2 visits

FAQs About Infections Under Tooth Crowns

• Can a crown infection occur years after placement?

Yes, infections can develop years after placement if the crown becomes damaged, ill-fitting, or oral hygiene declines.

• Is tooth pain under a crown always a sign of infection?

Not necessarily. Pain could result from sensitivity, a loose crown, or minor decay.

• How is a crown infection diagnosed?

Dentists diagnose infections using X-rays, visual examinations, and patient-reported symptoms.

• Will I need to replace my crown after an infection?

It depends on the crown’s condition. If it remains intact and functional, replacement may not be necessary.

• Can antibiotics alone resolve a crown infection?

Antibiotics can manage symptoms temporarily but are often paired with additional treatments like root canal therapy.

• Are infections under temporary crowns common?

While less common, temporary crowns can become infected if poorly fitted or if temporary cement allows bacterial leakage.
