I own four toothbrushes, each for a different particular use. One, I love. The others, I use simply because my dentist advised me to implement a "softer" brush. I found this advice to be incorrect, for these so-called softer brushes just don't do the job. I scrub my teeth at least 4 times a day and I like to use a different toothbrush each time. Drying out each individual brush is part of my regimen, and I find that once I reach the last one, the first one is dry and therefore sans any bacteria, though I give each one a quick microwaving just to be sure. These softer toothbrushes just don't do the job and my teeth feel dirty immediately after a hard brushing. I love the medium brushes because nothing feels as pure after a good cleaning. Sometimes I'll find ants on my brushes and I have to then go out and buy new ones. I use a mixture of boric acid and sugar to get rid of ants, and it works wonders. I don't know why my dentist would recommend a soft brush, they just don't work. Maybe they're in cahoots with the manufacturers of said ineffective toothbrushes, I don't know. Either way, I don't like it when rats come up my toilet, which they sometimes do. I call the county when that happens though, I think they're in charge of such things.
