Having had gingivitus (a hereditary gum disease) all of my adult life, I have needed to take extra care of my teeth. Over the years and after three surgeries (ten years apart) I now have a lowered gum line which results in wider spaces between my teeth. When used regularly I think these types of brushes work better than floss and the proof for me is when the dentist says there are no problems (like bleeding gums). So why is this brand better? It is because the little rubber coated handles DO NOT BEND. This is a big deal! Years ago with another brand.....the handles were likewise rigid and hard. And then this other (major) brand changed to a little handle that flexes. And all of a sudden, I could not clean my teeth because there was no control in wide gaps. If I tried to push the little brush against the tooth, the handle flexed. Imagine trying to get into any kind of a gap with something that is limp and flexible. So with great anticipation, I ordered this Pikster brand hoping they would be rigid and do the trick. And they did! Perhaps order several different sizes to find your best size. This product is perhaps the best on the market today. Also I have learned that electric toothbrushes really do clean better than manual. If you have a gum problem or want to keep your teeth and gums healthy, use an electric tooth brush and use these brushes (even if you don't floss). Use the Pikster between each of your teeth (and don't forget the very back where food hides). Do this routine at least morning and night. Other wise bacteria has time to take hold. It took me decades and much money given to dentists to learn this routine and I give the advice to you hoping to save you money and save you from surgical pain. Thanks to Pikster, my teeth feel clean again!
