An impacted tooth is a tooth that fails to emerge properly through the gums. This often occurs when there is not enough space in the jaw or when the tooth is misaligned. Commonly affected teeth include the wisdom teeth, which are the last molars that typically appear in late adolescence or early adulthood. Impacted teeth can lead to various dental issues, such as pain, infection, or damage to neighboring teeth. Dentists may recommend monitoring the situation or performing a procedure to remove the impacted tooth if it causes significant problems. Regular dental check-ups can help identify impacted teeth early.
