You should be brushing your teeth twice a day & flossing at least once a day. Most people brush in the morning when they wake up & brush & floss at night before bed. If you want to brush after lunch too, we highly approve. When you brush your teeth it should be for a full two minutes. Make sure you get the back & front sides of your upper & lower teeth & their biting surfaces. Floss with about an arm span’s worth of floss, using a clean two inches for each tooth to prevent cross-contamination from one tooth to another. If you’d like the dentist or hygienist to demonstrate proper brushing & flossing technique, please just ask during your visit!
