Pyorrhea is also known as periodontist is basically inflammation and deterioration of the tissue and bone surrounding the teeth. The condition is caused by several bacteria in combination, and is often worsened by a faulty immune system response - either a response that is too aggressive or a weak response.
To answer your question - no, pyorrhea is not contagious. The main reason for the development of pyorrhea is inadequate dental hygiene and, as mentioned before, an abnormal immune system reaction. Your immune system's response cannot really be controlled, apart from trying to stay healthy in general - if you have a disease such as diabetes or cancer, which affects your immune system, you are more susceptible to gum disease.
The best way to prevent the development of pyorrhea is to maintain excellent dental hygiene. This is well within your control, and only takes a little extra time and effort daily. You should brush your teeth thoroughly at least twice a day, and if necessary after every single meal; this need not be done with great force, but you should be sure to cover every bit of your gums and teeth. In addition, you should floss your teeth daily and also use an antibacterial mouthwash. You should also regularly visit your dentist, particularly if you already have or have had pyorrhea.
