I recently bought this product. It even removes food trapped between teeth that flossing misses yet is gentle on the gums. O should have bought one these years ago.
I am addicted to my cordless Waterpik! I use it after every meal. I am amazed that, after brushing and using pics, there are still bits that wash out - gross, but healthier for my teeth.
I use it every night and it's so much more fun than flossing. I fill it 2-3 times. It's great at getting to the hard to reach places. It removes food from pockets with ease.
