Dental knowledge
Most dental treatment is done to prevent or treat the two most common oral diseases, cavities and periodontal disease (gum disease or pyorrhea). Common treatments include dental restorations, extractions and surgical extractions, calculus removal and root canal therapy. Dentists also encourage the prevention of oral disease through proper personal hygiene, professional cleaning and evaluation at regular biannual checkups. Oral conditions can reflect systemic diseases like osteoporosis, diabetes or cancer. Many studies have also shown that gum disease increases the risk of diabetes, heart disease and premature birth.
