Wisdom teeth, also known as third molars, are large molars located at the back of the dental arch. There are four wisdom teeth, two on each side of the upper and lower jaws, and they typically start erupting during early adulthood, between the ages of 18 to 25. These teeth may need to be extracted for various reasons, such as jaw insufficiency, crowding, decay, or gum diseases. However, the decision to extract them depends on individual circumstances, and proper care and attention should be given after the extraction. Following the dentist's instructions, supporting the healing process, and promptly seeking dental attention for possible complications are crucial.
