During the treatment of teeth by a dentist or dental specialist the patient's head rests on a headrest. The position of the head towards the caretaker, as well as the comfort of the patient, are very important for a successful treatment. Such comfort is often prevented due to hairstyling that is not accommodated by the design of the headrest. The invention provides a U-shaped headrest that allows for comfortable resting of a patient's head on the headrest. The U-shape may be subject to a variety of mechanical changes, for example, making an opening bigger or smaller, or changes in the angle of the headrest itself so that it better fits the counter of a patient's head. Such changes may be made through manual, pneumatic, or electrical control, or combinations thereof.
