Dental hygiene is the drill to keep the mouth clean and is considered the best way of preventing cavities, gingivitis, periodontitis, and other dental disorders. It also helps to prevent bad breath. Dental hygiene is essential for all people to maintain the health of their teeth and mouth. A good set of healthy teeth have fewer cavities. They are clean and have minimal or no plaque deposits. The most common dental problems such as cavities or gum disease can interfere with your ability to eat and speak properly, recurring pain, and bad breath. Many people may not understand that poor dental health can have a significant, negative effect on the areas outside of the mouth, including the heart, diabetes, and chronic inflammation, such as arthritis.
