It might be a good idea to brush with the radio on, since dentists generally recommend brushing 3-4 minutes, the length of an average song. Using an egg timer is another way to measure your brushing time. Patients generally think they're brushing longer, but most spend less than a minute brushing. To make sure you're doing a thorough job and not missing any spots, patients are advised to brush the full 3-4 minutes twice a day, instead of brushing quickly five or more times through the day. Definitely, but most Americans don't brush during the workday.
Dentists recommend keeping a toothbrush at work.
Getting the debris off teeth right away stops sugary snacks from turning to damaging acids, and catches starchy foods like potato chips before they turn to cavity-causing sugar. If you brush with fluoride toothpaste in the morning and before going to bed, you don't even need to use toothpaste at work. You can just brush and rinse before heading back to the desk. If you don't have a toothbrush, rinsing your mouth with water for 30 seconds after lunch also helps. Brush teeth right after lunch, before you become absorbed in work.
