Wisdom teeth, also known as the eighth teeth in the dental arch, typically emerge in the early 20s. When healthy, properly aligned, and fitting into the biting plane, they can be valuable components of the dentition.
Wisdom teeth are usually the largest teeth in the oral cavity.
However, problems arise when wisdom teeth develop in improper axial positions due to crowding. This may result in horizontal, oblique, or outward/inward tilting, or being positioned away from other molars. For about 13% of individuals, wisdom teeth may not erupt at all (impaction) or may be entirely missing. In some cases, only one or a few wisdom teeth are absent.
Improperly positioned wisdom teeth can lead to crowding or damage to adjacent teeth, the jaw, or nerves. When wisdom teeth lean toward the second molars, they are more prone to decay due to increased plaque buildup and food residue. These teeth may also become trapped in soft tissues or the jaw, partially erupted, a condition known as impaction.
Partially erupted wisdom teeth are susceptible to bacterial infections, leading to painful inflammation, swelling, gagging, and general discomfort. Additionally, these teeth are difficult to clean with regular oral hygiene tools, making them more vulnerable to decay and gum disease.
Wisdom teeth causing such issues are often recommended for removal. Fully erupted wisdom teeth can typically be removed quickly and painlessly under local anesthesia. In cases where the tooth is partially erupted or impacted, surgical extraction is performed under local anesthesia.
To promote faster healing after the extraction, a collagen sponge is placed in the tooth’s socket, the wound is sutured, and antibiotics are prescribed.
Proper post-operative care is crucial for a smooth recovery. This includes maintaining good oral hygiene, cooling the affected area, taking prescribed medications as directed, and handling the area with care. These steps help ensure the recovery process is as quick and trouble-free as possible.
