Plaque buildup on teeth and along the gum line is the most common cause of gum disease. Plaque is a bacteria-containing sticky covering. With an inflammatory response, the immune system attempts to eliminate plaque. If you have swollen or bleeding gums or are concerned about anything related to your mouth, consult an Emergency Dentist 24/7 in Kennewick, WA 99336. Call 1-888-896-1427 to schedule a same-day dental appointment.
