Some people have more of a gag reflex than others. If when you brush, you occupy your mind with something else while still using the proper brushing technique, you won't focus on gagging. For example, try sitting in a chair when brushing, straighten one leg, then lift and hold it in the air.
Antibiotic Resistance Threats in the US. Antibiotics are powerful tools for fighting illness and disease, but overuse of antibiotics has helped create bacteria that are outliving the drugs used to treat them. Antibiotic resistance is a quickly growing, extremely dangerous problem. World health leaders have described antibiotic-resistant bacteria as nightmare bacteria that pose a catastrophic threat to people in every country in the world.
The discovery and use of antibiotics for bacterial infections is considered one of the most important breakthroughs in medical history. Unfortunately, bacteria are extremely adaptable, and the overuse of antibiotics has made many of them resistant to medical treatment. This has created serious problems, especially in hospital settings. Antibiotics are ineffective against viruses -- including those which cause most upper-respiratory tract infections -- and many leading organizations now recommend against the routine use of antibiotics unless there is clear evidence of a bacterial infection.
