Conditions such as heart disease, diabetes, stroke, rheumatoid arthritis and other inflammatory conditions have been shown to often go hand in hand with periodontal disease. The best way to improve overall health, including the mouth, is to balance the body chemistry. Bacteria, viruses, yeasts, parasites, and molds will attack the body until balance is restored. Nutritional support is effective with the non-surgical support. Biological periodontal therapy focuses totally on the bacteria living in the pockets around the teeth. Many use a phase contrast microscope to check for pathogens and progress of treatment. The pockets are irrigated (flushed out) with all-natural anti-bacterial solutions. Then root planing is done where the hard material under the gums is scraped off. The patient is often asked to irrigate regularly as part of their home hygiene ritual. Ozone therapy may be used to kill off bacteria sensitive to oxygen.
