1.  A.  According to Colgate’s Oral and Health Basics, gum disease is the leading cause of tooth loss. “Moreover, a Surgeon General’s report issued in May 2000 labeled Americans’ bad oral health a “silent epidemic” and called for a national effort to improve oral health among all Americans,” the site says.

2. B.  Periodontal means, “around the teeth” which is the location of your gums.

3. C. Plaque grows both on the teeth and below the gum line. When it reaches too far below the gum line, you need to see a dentist to have it professionally removed.

4. C. Bleeding gums is one of the first signs on gum disease. Others include bad breath; receding gums; red, swollen, or tender gums.
