2. Gum Disease
According to the Centers for Disease Control and Prevention, almost half of adults over 30 in the US have some form of gum disease. This condition is caused by bacteria built up around your gumline and has turned into plaque (a soft, sticky, colorless film). In its earliest stages (gingivitis), you may experience red and swollen gums. If your gingivitis goes untreated, your inflammation can develop into a more severe condition called periodontitis. Periodontitis can cause your tissue to recede, bone to wear away, teeth to loosen, and your teeth could even fall out. Luckily, gum disease is preventable by practicing good oral hygiene, and its more severe stages can be treated with deep cleaning (and, in some cases, surgery).
