Yoghurt bacteria vs. tooth-decay-causing bacteria: probiotic dental hygeine?

Question

I'm not suggesting eating youghurt INSTEAD of brushing your teeth. Brushing and flossing are OBVIOUSLY the best approach to taking care of your teeth.

But there are times when you're on the go and can't stop, etc., when you need a snack or light lunch during the day. I think youghurt might be not just safe to eat but more beneficial to my teeth than other foods.

The bacteria in yoghurt are supposed to thrive in acidic environments. Decay-causing bacteria excrete acid, which cause decay. I realize they're not necessarily the same acid.

Would the bacteria in unsweetened yoghurt compete with, displace, overwhelm, kill or otherwise counter the presence of decay-causing bateria on the teeth...?

Has any research been done on this...? How significant is the difference...?

(I specify unsweetened because sugar would remain long after you swallowed most of the youghurt bacteria.)

Please cite your sources. Thanks to all serious answers

Answer 1

The bacteria in the mouth that cause cavities are not affected by the bacteria in yogurt.

Most foods are acidic so soaking your mouth in yogurt is not a good idea.
