Operculectomy is a dental procedure performed to remove an operculum, which is a flap of gum tissue that partially covers an erupting tooth, typically a wisdom tooth (third molar). This flap can become swollen, inflamed, or infected, a condition known as pericoronitis.Operculectomy is generally a safe and effective procedure for managing pericoronitis and promoting oral health. However, it's essential to follow your dentist's post-operative instructions carefully to ensure proper healing and to minimize the risk of complications.
