Which procedure is not commonly performed in general dental practices?

In the context of general dental practices, heart surgery is definitively not a procedure that is performed. General dental practices focus primarily on oral health, including preventive care, restorative treatments, and common surgical procedures related to the teeth and gums. These may include tooth extractions, root canal treatments, and various other dental surgeries that are directly related to the oral cavity.

Heart surgery, on the other hand, is a complex medical procedure carried out by specialized cardiothoracic surgeons in a hospital setting, dealing with conditions affecting the heart and major blood vessels. This separation between general dentistry and heart surgery highlights the specialized skills and environments required for different types of medical procedures, making it clear that heart surgery falls outside the scope of what is performed in a dental practice.
