Hypnosis is the quieting of the conscious mind. It is characterized by a trance state. Trance is a state of mind in which our normal awareness of the outside world is reduced and our attention is focused on some activity, physical stimulus, image fantasy, thought or feeling. People enter this state every day when lost in thought or day dreaming, working out at the gym, reading or listening to music. When someone is hypnotized, they are given a set of instructions which assist them in achieving the trance state. And it is now being used in general dental care.
Some applications of hypnosis in preventive dental care include controlling a strong gag reflex, treating chronic facial pain and modifying habits like teeth grinding.
The use of hypnosis in dentistry falls into two categories: therapeutic and operative. The therapeutic use of hypnosis includes relaxing the patient, removing their anxieties, fears and pain, helping him remain comfortable throughout a dental procedure and developing positive habits of personal oral health care. Hypnosis can be used to help eliminate nail biting, thumb sucking, abnormal swallowing patterns and smoking. Operative uses include relaxation and the control of salivation and bleeding, the prevention of gagging and nausea, reduction of post operative swelling, discomfort and shock and promotion of post operative healing and recovery.
Hypnosis can help reduce the tension, nervousness and fear of pain that certain people have about the dentist and thus allow for proper general dental care. Once the patient has been hypnotized, he is asked to imagine his favourite place, a place that makes him always feel relaxed and happy. This might be a place such as a garden, a beach or a river. They are to imagine how their five senses would respond to this place.
The post hypnotic suggestion is given before awakening the patient that they will be able to relax as deeply as this once they are seated in the dental chair. They are asked to close their eyes when they sit in the chair, take three deep breaths and then they will be able to relax and enjoy their special place.
Apart from mere relaxation, it may be possible to help patients who have the unfortunate habit of gagging every time something is placed in their mouth. It is a natural reaction to prevent choking but some people have this so highly developed that any dental work becomes impossible. With light hypnosis, patients can learn to effectively control this gagging reflex.
Under deep hypnosis, a patient can make an area feel completely numb and even have a tooth extracted without feeling anything. Hypnosis can even be used in conjunction with nitrous oxide (laughing gas) to enhance the effect and provide deeper relaxation.
