How bad is it to not brush your teeth for the night?

And how about only once a day?How bad is it to not brush your teeth for the night?
Brushing day and night is very important, if you only brush at night, your breath will smell bad in the morning, if you only brush in the morning, your teeth will be dirty at night and you will get cavities easily, because of all the bacteria.





If you only want to brush once a day, brush at night instead of in the morning, your mouth is dirtier at night. Maybe instead of brushing your teeth in the morning, you can use only mouth wash in the morning and gargle really well.How bad is it to not brush your teeth for the night?
Just imagine the smell if you did not brush at bedtime....! Bacteria work all night....regardless.
