### What is a Dental Abscess? A dental abscess is an infection in the mouth, face, jaw, or throat that starts from a tooth infection or cavity. It is common in people with poor dental hygiene and can result from not getting proper dental care in time. ### Causes The main cause of a dental abscess is the direct growth of bacteria from a cavity into the soft tissues and bones of the face and neck. Poor oral hygiene, smoking, alcohol, a poor diet, and certain medical conditions and medications can increase the risk of cavities and subsequent abscesses. ### Symptoms Common symptoms of a dental abscess include: - Severe toothache - Sensitivity to hot and cold - Swelling in your face or cheek - Tender, swollen lymph nodes under your jaw or in your neck - Fever - A bad taste in your mouth ### When to Seek Medical Care If you suspect you have a dental abscess, contact your dentist immediately. If you cannot reach a dentist, go to a hospital's emergency department, especially if you feel unwell. ### Diagnosis A dentist can often diagnose a dental abscess through a physical exam. X-rays may be needed to identify smaller abscesses deep within the tooth. ### Home Treatment Over-the-counter pain relievers like ibuprofen, naproxen, or acetaminophen can help manage pain. If the abscess ruptures, rinsing your mouth with warm water can help cleanse the area. ### Medical Treatment A dentist may need to drain the abscess by cutting it open or through the infected tooth during a root canal procedure. Antibiotics and pain relievers are often prescribed to manage the infection and pain. ### Follow-Up Care Follow your dentist's instructions for follow-up care, which may include multiple visits or a referral to a specialist. Proper dental hygiene and regular checkups can help prevent future abscesses. ### Prevention Daily brushing and flossing, along with regular dental checkups, are crucial for maintaining good dental health and preventing tooth abscesses. ### Recovery Recovery from a small dental abscess is generally good once it has been drained. Follow-up care is essential to ensure the infection does not worsen or spread. Untreated abscesses can lead to severe complications, including spreading to the jaw, neck, or even causing sepsis.
