The Hard Toothbrush is the way to go
The Benefits of Using a Hard Toothbrush
The hard toothbrush gets the job done efficiently. I don't get how anyone could use soft bristles when they don't scrub as hard. The idea of brushing your teeth is to remove all the food and stuff that gets caught on them throughout the day, so why not remove it right? The hard brush scrubs harder and does more than the medium or soft brush. You don't need to be easy on your gums, you need to toughen them up and let them know who's boss.
Where to buy
I have found it increasingly harder to find a hard toothbrush these days. If you go to the store and check out the dental section you will find a pretty even split between soft and medium brushes, but you will have trouble finding a hard brush. I don't know why this is but I have my suspicions. Perhaps the large corporations that create the toothbrushes are looking to give us less efficient tools to keep us coming back and having to spend more money with them. I really can't think of why else there would be a drop-off in the number of hard brushes. Like even 5 years ago I could go around and spot countless numbers of hard brushes. These days the only one I can find is a hard brush made by Reach. It's a treasure hunt just to brush my teeth the right way.
So there you have it. I sport the hard brush as should you if you are all about maximum cleaning. Everything about the hard brush makes sense.
