Overview
A dental crown, also known as a cap, is a commonly used dental restoration tool. It is a coverage placed over a damaged or decayed tooth to repair its shape, size, and strength, as well as improve its appearance. While dental crowns are designed to be durable and long-lasting, they can still become infected due to various reasons, including poor oral hygiene practices, inadequate crown fit or malfunction, trauma to the tooth or crown, and excessive teeth grinding. In this article, we will discuss the common signs and symptoms of a dental crown infection, the potential causes behind it, and how to prevent such an infection.
Symptoms of Infection in a Crown
If a dental crown becomes infected, patients may experience a variety of symptoms. These can include:
-
Tooth sensitivity to temperature changes or sweet foods: The infected tooth or crown may become more sensitive to hot or cold foods or drinks, causing pain or discomfort when eating or drinking.
-
Pain or tenderness around the crown: Patients may experience pain or tenderness directly underneath or around the crown, which may worsen when biting or applying pressure.
-
Swelling or inflammation of the gums: Inflammation or swelling of the gums in the area of the crown may indicate an infection involving the underlying tooth.
-
Discolored or foul-smelling discharge: Patients may notice a clear, yellow, green, or brown discharge coming from around the crown, which could be a sign of an infection.
-
Fever and swollen lymph nodes: Unexplained fever and swollen lymph nodes in the neck may suggest an underlying infection.
Causes of Infection in a Crown
Infections in dental crowns can occur due to various reasons, including:
-
Poor oral hygiene: Bacteria can thrive in a dental plaque, which forms on the surface of teeth. If not properly cleaned and removed, this can lead to tooth decay and eventually an infection under the crown.
-
Temporary crown: If a temporary crown is used for too long, it may become poorly fit or damaged, allowing bacteria to invade the tooth and cause an infection.
-
Malformed or maligned crown: A crown that is misshapen or incorrectly fitted may crowd the gums and trap food particles, leading to gingivitis and periodontal disease. This can increase the risk of infection.
-
Trauma to the crown or underlying tooth: A blow to the face or a hard object striking the tooth and crown can damage the crown, loosen the bond, or expose the underlying tooth to an infection.
-
Excessive teeth grinding: Teeth grinding, particularly during sleep, can exert excessive pressure on the crown and underlying tooth, potentially causing a fracture or decay.
Preventing Infection in a Crown
To prevent infection in a dental crown, it is essential to practice good oral hygiene habits, including daily brushing and flossing, and to schedule regular check-ups and cleanings with your dentist. If a temporary crown is used, it should be replaced as soon as possible to prevent bacterial growth. Additionally, if you notice any signs or symptoms of an infection, such as increased sensitivity or pain, you should及早 contact your dentist for an examination and treatment.
##Infection in a dental crown is a possible并发症 that can affect the health and aesthetics of your teeth. By understanding the common signs and causing factors of such infections, taking proactive preventive measures, and noticing any symptoms early on, you can safeguard your dental crown and maintain a healthy, radiant smile.
