I love electric toothbrushes and there are definitely dentists on each side of the Oral B vs. Sonicare camp. They get your teeth really clean and force you to brush longer.
You really should try and get into the habit of flossing, if not just for hygiene (you really don’t want food rotting and calcifying in between your teeth) and oral health reasons but for cardiac reasons as well. There are studies that show that a lack of flossing can contribute to cardiac problems.
Try those pre-loaded, disposable flossers to get you started and after a few weeks, what seems like a chore will become easy, second nature. Once you start flossing more often, you’ll be completely grossed out by what stays in your mouth when you don’t floss and no amount of swishing or mouthwash will cut it.
