For patients with a high caries risk (ie. likely to get cavities), the dentist will often prescribe a high-fluoride tooth-paste or rinse (for instance PreviDent 5000) for the patient to use twice a day. The directions to the patient are to 1) brush your teeth for 2 minutes with regular toothpaste right before bed-time. 2) Rinse your mouth. 3) Use a dry toothbrush with the prescription toothpaste to re-brush your teeth for another 2 minutes (gently scrubbing all surfaces). 4) Spit, but do not rinse. 5) Go promptly to bed without eating or drinking or rinsing. The goal is for the residual fluoride to 'soak into your teeth' increasing their natural strength. My personal suggestion is, even if you don't have the prescription-grade toothpaste, use your regular fluoridated toothpaste in the same manner. Those hours you spend asleep can either benefit your teeth if you've brushed properly, or allow the bacteria and germs to accumulate and wreak havoc!
