The purpose of patient-doctor communication: to help patients understand the objective existence of periodontal problems and to inform them that these problems are solvable problems, problems that must be solved, the benefits of solving them and the dangers of not solving them. The language should be firm and decisive, plain, easy to understand, logical, with clear cause-and-effect relationships, and convincing. Repeat the emphasis when necessary to draw the patient’s attention and help him or her realize the dangers of periodontal disease. Examples of communication with patients before, during and after periodontal treatment: A few words to tell patients before treatment 1. Bleeding gums are inflammatory and destructive because the teeth are not clean (medical theory considers them to be bacteria). 2, teeth and mouth are not clean, so bad breath. 3, gum destruction, the following bone also follow the destruction, that is, the root of the teeth destruction (periodontal disease), the teeth will be loose and fall off. 4. As the saying goes, “old people lose their teeth”, you may also think that you will naturally lose your teeth when you get old, but in fact you will not lose your teeth as long as you keep your teeth clean, and you will not lose your teeth even at the age of 100. A few words to tell patients during treatment 1, gum inflammation, bleeding when touched, the treatment process will inevitably bleed, clean up, gum inflammation subsided, will not bleed again. 2, the calculus has grown into the gums, I must clean it up, it may hurt a little, but it must be cleaned up even if it hurts, please insist on cooperating with me, and if necessary, use some anesthetic. 3, gum redness and swelling after treatment we hope will reduce the swelling, after the swelling will be manifested as gum recession, the root will be more exposed than now, will be more afraid of cold and acid, that must also be cleaned, or the gums and bone will be destroyed more powerful. (Desensitizing toothpaste is available). 4.After cleaning the calculus, the gap between the teeth will be more obvious and there will be food stuffing, you must and can only use dental floss or a toothbrush to clean it in time. 5. In fact, before the treatment, you have calculus between your teeth every minute, but you don’t feel it. A few words to the patient after the treatment I have cleaned your teeth and it is up to you. How do I keep my teeth clean? Just do the following three things 1. Toothbrush: Brush all sides of each tooth with a toothbrush 3-4 times a day for 3-5 minutes each time. 2.Floss or toothbrush: Brush the side of each tooth cleanly, 1-2 times a day. 3. Come to me every 6 months~1 year so that I can monitor your dental hygiene. After periodontal treatment patients are asked to remember three phrases: 1. Clean teeth are healthy; 2. Every tooth should be clean; 3. Every side of every tooth should be clean.
