As I said my profession is selling dental materials, I have a very good friend professor at the university with the object of research. He told me that it is good to rinse the toothbrush well before each use and that we should often leave it in a glass with oxygen or in an alcoholic solution or even in a water solution with vinegar.Thanks for that. I note the following from your link:
"Is There Anything Else I Can Do to Lower My Risk for Bacterial Endocarditis?
- Practice good oral hygiene. Brush your teeth at least twice a day; floss at least once daily; rinse with an antiseptic mouthwash at least once a day. Good oral and dental health is very important for patients at risk for endocarditis."
Also razors are good before use rinse well with warm water. I use safety razors and blades that are very cheap about 0.20 euros each which I change every 2-3 shaves. Also ALWAYS rinse before use with hot water and often with isopropyl alcohol.
I also always have it at home and when I travel I take some doses of antibiotics in case I have an accident or a deep cut. Generally know that we all need to have a good pathologist or family doctor that we can consult at any time, still do not hesitate to go to a hospital in outpatient clinics if you are injured.
