The market for pediatric dental crowns expanded at a rate of 7.8%, rising from $6.69 billion in 2022 to $7.21 billion in 2023.

With many people wearing it, an infected dental crown is a severe issue often dismissed as just a normal part of aging. Whether the height is infected or not, inflammation of the gums is not something anyone wants to experience.

When you add the cause of crown infection, it sounds even worse. The idea of an infection spreading to your bloodstream and throughout your body is unpleasant. If your dental crown is infected and causing inflammation and bleeding in your mouth, you need to take action.

This guide will help you to understand the signs of an infected crown, what they mean, and what course of action you should take.

Persistent Pain

One of the primary signs of a dental crown infection is persistent pain around the affected tooth. It may show an infection if you notice a throbbing pain or heightened sensitivity to hot or cold substances.

Such discomfort is often a result of inflammation or nerve damage caused by bacteria that have infiltrated the area surrounding the dental crown. If the pain persists or worsens, you must consult your dentist for an evaluation.

Swollen or Inflamed Gums

Healthy gums are crucial to the stability and health of dental crowns. If you observe swelling or inflammation in the gum tissue surrounding the crowned tooth, it may be a sign of infection.

When brushing or flossing, swollen gums may appear red, puffy, or even bleed. In some cases, you might also notice a foul taste or odor in your mouth, which can indicate an underlying issue.

Bad Breath

Bad breath, also known as halitosis, can be more than a result of the food you consume. It can be a symptom of a dental crown infection.

The presence of bacteria in an infected crown can release foul-smelling gases, leading to chronic bad breath. If your bad breath persists despite maintaining good oral hygiene practices, it's time to consult your dentist to rule out any underlying dental issues, including a crown infection.

Sensitivity to Temperature

Bacteria can enter the crown during installation or due to bad oral hygiene. This makes the tooth sensitive to temperature. The germs can cause the gums around the crown to hurt, which can make it very hard to eat or drink hot or cold things. If this happens, you should see a dentist immediately to get a professional opinion.

The dentist can take X-rays and look at the crown and the tissue around it to ensure the infection hasn't spread. If this infection is treated quickly, it can be cleared up before it spreads and does more damage to the mouth and jaw.

Pus or Discharge

The presence of pus or any type of discharge around the dental crown is a definite sign of infection. Infections can cause an accumulation of pus within the gum tissues, leading to swelling and discomfort.

If you notice any oozing, discharge, or unpleasant taste in your mouth, addressing the issue is essential. Delaying treatment can result in further complications, such as spreading the infection to surrounding teeth or jawbone.

Loosening of the Crown

A dental crown that becomes loose or dislodged without trauma can indicate an underlying infection. Bacterial infection can weaken the bond between the crown and the tooth, causing it to feel loose or unstable.

If you notice crown chipping that causes any movement or changes in the fit of your dental crown, it is essential to schedule an appointment with your dentist as soon as possible. Remember, taking proactive measures is critical to maintaining your dental health. Check more on this page for dental crown on how to keep your smile healthy and infection-free.


If the fever is with throbbing pain, then it is likely that the infection has reached the crown. It is usually caused by the body working to fight infection and rid the body of bacteria. The fever can range in intensity but must be continuously monitored and brought to a medical professional's attention if it worsens.

A dental crown infection can become so severe that it reaches the bloodstream, requiring further investigation and treatment. In such cases, a medical professional may order a course of antibiotics or any other medicines that may be necessary. Regardless, it is essential to seek care immediately if a fever is present.

Discoloration of the Crown

The discoloration is due to bacteria and other microorganisms accumulating on the crown's surface. These organisms cause the crown to become stained or yellowed, a sign of infection. The discoloration can even penetrate the peak itself, leading to discoloration of the enamel.

In addition, a patient may notice inflammation in the gums surrounding the crown or tenderness in the affected area. This inflammation and tenderness may be caused by the presence of an infection.

Difficulty in Biting or Chewing

Dental crowns are generally placed over a damaged tooth to protect it from further damage. While they can be very effective in preserving teeth, they can also create a tight seal over the tooth that can trap bacteria.

If a dental crown infection develops, it may cause the crowned tooth to feel tender and give you difficulty when biting or chewing. Common symptoms include tenderness along the gum line, chewing pain, and a leaking crown.

Prolonged Healing Time

Following the placement of a dental crown, there is a standard healing period during which any discomfort or sensitivity should gradually subside. However, if you notice that the healing process is taking longer than expected or that the pain persists beyond a reasonable timeframe, it could be a sign of a dental crown infection. Delayed healing suggests that the body's natural defense mechanisms struggle to overcome the infection.
