These brushes are amazing! So very soft and conforming to your teeth and gums. I don’t think I can ever go back to a regular brush again! Thank you from a woman who has upper and lower implants and now dealing with stage 4 cancer! My gums get tender at times from treatments. I only found your products because a high school friend, highly educated in dental hygiene, gave her whole 50th class reunion a brush! I have since ordered brushes and will give my family some!
