Don't rinse your mouth immediately after brushing, as it'll wash away the concentrated fluoride in the remaining toothpaste. Rinsing dilutes it and reduces its preventative effects.

The "333 dental rule" refers to two different concepts: a hygiene guideline (brush 3 times a day for 3 minutes, replace brush every 3 months) and a temporary toothache relief method (take 3 ibuprofen tablets, 3 times a day, for 3 days).
