Query: The Best Ulra Soft Bristle Toothbrush

I've used many so-called ultra soft toothbrushes in my 58 years of life, and in my opinion The Preserve toothbrush stands alone. For the last 2 years I have been using Preserve. It is truly the best for comfort and good dental hygiene. My dentist has noticed my gums are much healthier.
