No offense to any OCD people out there, but teeth brushing should take 5 minutes.
20 minutes is average.
20 minutes at 60 mph.
Time = Distance/Speed So time = 9 miles / 20 mph = 9/20 hours = 60*9/20 minutes = (60/20)*9 minutes = 3*9 minutes = 27 minutes.
20 minutes
In slow walking pace, about 15 - 20 minutes.
20 thousand gallons I know that's a lot
You should try to avoid brushing your teeth straight after drinking coke (and soft drinks, energy drinks, sports drinks and juices) as these have a lot of acid in them with softens the enamel of your teeth. Rinse with water after drinking something acidic and wait 20-30 mins before brushing. Brushing too soon will wear off the softened enamel. However, not brushing at all will leave all of that acid (and sugar) in your mouth for much longer which puts your teeth at risk for wearing down and getting decay. The best idea is to limit the amount of acidic drinks you have. And if you do have them, try to have with a meal, instead of sipping for 20mins (or longer). Long-term acid (and sugar) in your mouth only results in harm for your teeth. Look after your teeth. Dentures are no fun.
plaque begins to form on your teeth within 20 minutes of brushing. it feels more prominent when it drys out. many people are mouth breathers at night. also the actions of chewing and speaking act to self cleanse the mouth, this is not happening when you sleep. if someone did not brush before sleeping this dirty feeling is even worse
