Should i use mouthwash immediately after brushing and flossing? if not, how long should i wait before using mouthwash?

Immediate or delayed use of mouth wash will not affect the efficacy of brushing. You should brush thoroughly and use a floss as well and get dental check ups as advised by your dentist.

Mouthwash contributes approx 1% to overall oral health efficacy. Brushing 2 FULL MINUTES by the clock 2x/day, using a timer, w soft t'brush & pea-sized portion of fluoridated t'paste removes about 65% of harmful bacteria. FlLOSS removes bacteria from the 35% of tooth surfaces that a brush can't reach. You MUST see Dentist 2x/year. Mouthwash is an adjunct to, not a substitute for, any of these step
