The most common types of dental emergencies include severe toothaches, knocked-out teeth, chipped or broken teeth, and abscesses. Severe toothaches can indicate deep decay or infection, requiring immediate attention. Knocked-out teeth need prompt action to increase the chances of saving the tooth. Chipped or broken teeth can result from trauma or biting hard objects, often needing restoration or extraction. Abscesses are serious infections at the tooth root or gums, causing pain and swelling, and require urgent treatment to prevent the infection from spreading. Addressing these issues promptly can help alleviate pain and prevent further complications.
