More than likely not. Dental hygiene recommendations are a shit show. Almost as bad as diet.

I’d advise what I advise everyone, don’t believe me and doubly disbelieve what you were told as a kid (e.g. cereals are actually awful for you and fats are the corner stone of a healthy metabolism and long term nervous health). Look it up, see what you find.

I was told (by a dentist) that I was overbrushing (only twice a day, but for more than 2 minutes at a go) and that I was excessively abrading my enamel, which was making my sensitive teeth worse. I was also warned to knock the lysterine on the head, because its been connected to damaging your internal fauna which has all kinds of negative effects. So I did both, and my morning breath improved no end as a side-effect.

My dentist recommends against mouthwash unless there’s something going on that can’t be treated (like when I was pregnant), and then she gave me a prescription mouthwash that uses a different chemical than alcohol to clean. She says the dryness caused by alcohol/menthol gives bad bacteria a better environment than if you don’t use it at all.

I also floss before rinsing all the toothpaste from my mouth, that way I’m getting some fluoride action between my teeth.

The toothbrush can also make a difference. I used to get my toothbrushes at the dollar store. I had to pick out a $3 brush at a grocery store one time and in a month, my gum receding was almost completely better! And this was while pregnant, a notoriously difficult time to maintain dental health, let alone improve things.
