    Tonsillitis - Cause

    Tonsillitis is usually caused by a virus. Bacteria can also cause tonsillitis. The most common bacterial cause of tonsillitis is group A beta-hemolytic streptococcus (GABHS), which also causes strep throat.

    Tonsillitis can also be caused by fungi or parasites. But these causes are rare in people who have healthy immune systems.

    The Importance of Early Dental Visits

    At the sight of my son's first tooth, it dawned on me: I had been so focused on every other detail of his development that I knew almost nothing about dental care for little choppers. According to Clarice Law, DMD, MS, assistant professor in the Pediatric Dentistry and Orthodontics sections at the UCLA School of Dentistry, it pays to start dental visits early.

    How tonsillitis is spread

    Tonsillitis is spread by close contact with an infected person. Droplets of disease-causing agents (pathogens) pass through the air when an infected person breathes, coughs, or sneezes. You may then become infected after you breathe in these droplets. Infection can also occur if pathogens get on your skin or on objects that come in contact with your mouth, nose, eyes, or other mucous membranes. Symptoms usually appear about 2 to 5 days after exposure.

    A person with tonsillitis caused by strep bacteria is contagious early on and, without treatment, can remain so for up to 2 weeks. Antibiotics shorten the contagious period, and an infected person is no longer contagious about 24 to 48 hours after beginning antibiotic therapy.

    Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.
