It is possible to grow teeth at the age of 18. Teeth that emerge in adulthood are generally referred to as supernumerary teeth or wisdom teeth. As wisdom teeth develop, they may pierce through the gums, causing pain and swelling, which can affect daily life and eating. It is recommended that patients seek timely medical attention at a hospital, where imaging can be used to evaluate the specific development and mobility of the tooth, as well as to check for periodontitis and dental calculus. If dental calculus is present, ultrasonic cleaning should be performed to remove it.
