Wisdom tooth pain can range from being a cause of irritation to potentially serious health complications, in either case visiting the dentist for wisdom tooth pain is the best course of action.   Wisdom tooth impaction can cause pain and infection. Brushing these teeth can be challenging. When food and bacteria get stuck between a wisdom tooth and its surrounding teeth, it can cause tooth decay and gum infection called pericoronitis. It is common for wisdom teeth that are crowded to lean sideways and rub against the cheeks. As a result, cheek ulcers and chewing difficulties may develop.   An abscessed tooth or dental abscess can cause severe pain and discomfort. Some people delay treatment because they cannot get an appointment with a dentist or are worried about paying for an ER or urgent care visit because they suffer from dental pain or infection.
