So had a couple of cavities at the dentist this week. They suggested I use a different toothbrush....so I bought a new Oral-B Triumph.....I LOVE to brush my teeth now! Seriously...never thought I would say that! It has a timer that syncs with it that tells me to switch quandrants every 30 seconds! It even has a cute smiley face that smiles at me when I have brushed for 2 minutes!
