Here's one in the category of "Has anyone else noticed this?" For years I have bought my toothbrushes at large department stores, usually WalMarts. They have large displays of toothbrushes, a good variety of all types and sizes. Over time I have noticed that the smaller the toothbrush, the less its life expectancy. Never mind, I prefer larger toothbrushes anyway. I have also noticed that the sparser the bristles, the shorter the life expectancy. Never mind, I prefer the fuller bristled large headed brushes, almost always an Oral B.
For about the last couple of years I have noticed that the usually ample supply of straight shaped, fuller bristled, large headed brushes have disappeared. Completely disappeared! I have asked at WalMart and been told that they are "not available". I have checked a variety of smaller drug stores, again being told they can't get larger headed (adult sized) toothbrushes. So, I contacted Oral B. They told me that they did indeed have larger sized brushes available, suggesting an "Indicator 60". No, none of their brushes are straight shaped. In spite of Oral B's claim, I have been unable to get a larger brush anywhere.
Here are a few thoughts. Small brushes wear out faster than large brushes. A Win for the manufacturer and the retailer if we can be weaned onto smaller brushes. Sparser bristles wear out faster than fuller brush heads. A Win for the manufacturer and the retailer if we can be weaned onto sparser headed brushes. I am starting to get the drift. Is there a conspiracy here? Are we consumers being quietly bilked?
Next time you are at a large display of toothbrushes, check it out. They are all small headed, poorly shaped brushes. A flat handle is easier to control so why are handles almost all rounded these days? They have coloured bristles angled back and forth, odd shaped heads rarely with parallel sides, all small, all sparsely bristled. Check the web. Look for an adult sized, full bristled brush with a straight, flat handle and parallel sided heads of the sort that were everywhere to be found just two or three years ago. Good luck. I'm still looking.
