Edit: Since it's come up a couple times in the comment, I'll add that there's evidence use of a water flosser is more effective than dental floss.

I floss and electric toothbrush every night. My dentist routinely complements my hygiene. Every cavity I’ve had filled in the past 8 years started from before I had an e-brush.

At a recent visit after remarking on how little plaque I had, my dentist asked if I brush twice a day. I told him no, only once a day.

He immediately changed his tune and told me that I should brush twice a day for better results.

I think he’s in the pocket of Big Paste.

Healthy teeth have a lot to do with genetics too. I’m a once/day brushed (with a powered brush) and never flush unless something’s stuck in my teeth and I don’t get cavities or have other teeth and mouth problems. My wife brushes twice a day, flosses, and uses mouth wash, and has had 12 root canals, and has cavities 25% of the time she gets her cleanings done.

There are two other main differences between us. She loves sugar and I’d prefer anything salty. I’m sure this isn’t helping her and is helping me since sugar is our mouths’ enemy.

[–] [email protected] 31 points 3 days ago* (last edited 3 days ago) (1 children)

The sugar is honestly probably the biggest factor here. Plaque is just bacteria poop, and giving them a bunch of sugar is basically speedrunning their growth and telling them to produce as much poop as they possibly can.

[–] [email protected] 7 points 2 days ago* (last edited 2 days ago)

What I left out is that I don’t know anyone in my family with teeth issues and she definitely does. Her mother had garbage teeth as does her father. But yeah, sugar is bad for you period.

Not brushing in the morning and at night is noodling my melon. Always brushed twice a day, floss at night. Surely you have morning breath everyday?

After going with a sonic toothbrush, I felt my teeth were actually clean. Much cleaner than before.

[–] [email protected] 20 points 3 days ago (1 children)

This was my experience as soon as I went electric too, yes. If anything, the only thing that's surprising about the article title to me is that it's only 20% more plaque!

[–] [email protected] 7 points 3 days ago

Maybe it's because the authors gathered research papers on all types of electric toothbrushes?

In my experience, the difference between manual and electric toothbrushes is huge. I'm no longer nervous about visiting my dentist.

[–] [email protected] 61 points 3 days ago (5 children)

I feel like it’s more than that…

When I switched to electric 7 or 8 years ago, I really didn’t like it. It was super uncomfortable and tickled my mouth.

I just powered through it because I was told that I would get used to it.

Indeed I did get used to it and quickly began to feel that I had never actually properly brushed my teeth before going electric.

Part of what helps is the little extra pulse every 30 seconds and auto shut off after two minutes. Really keeps you on track with 30 seconds in each quadrant of your mouth.

Two minutes is a long time so having the timer built into the toothbrush is super helpful.

Only concern to note is that applying too much pressure and/or using the maximum vibration setting can be bad for your gums and cause recession.

Be very gentle with the electric toothbrush so that you do not cause any excessive gum recession.

Once you get used to electric, a conventional toothbrush will seem archaic.

An electric toothbrush and more importantly a water flosser have saved me thousands in dental treatment costs.

[–] [email protected] 11 points 2 days ago (3 children)

Right now electric toothbrushes just need to become more repairable.

[–] [email protected] 2 points 2 days ago

Having to buy new ones because the battery can no longer hold a charge seems so wasteful.

I've got a waterpik and I just can't get on with it at all. How on earth are you supposed to use it? You can't use it sideways because there's no pressure, so it has to be sort of vertical, which feels really weird to aim and you can't see what you're doing. The last time I tried, it was like I hosed down the bathroom, with water everywhere. It also managed to be so powerful that it cut my gums.

[–] [email protected] 14 points 2 days ago (1 children)

The right way to use one certainly doesn't feel elegant. You just have to flip it around a lot while facing down at the sink and hope you don't snipe a spider on the ceiling by accident.

[–] [email protected] 3 points 2 days ago

Made me chuckle

[–] [email protected] 9 points 2 days ago* (last edited 2 days ago) (1 children)

Use the lower pressure settings to start and just get a feel for manipulating it around your mouth. I try to spray between my teeth and you can reach that gap from the sides as well as the bottom.

I will add that a waterpik is a really nice tool to add to your dental hygiene routine.

[–] [email protected] 23 points 2 days ago (4 children)

I would like to taint this info with the knowledge that pik means 'penis' in Dutch

[–] [email protected] 18 points 2 days ago (1 children)

oh wait till I tell you what taint means!

I used to brush 3 times a day, but I’m not using the filthy office restroom for my dental hygiene, so dialed it down to two. I can’t fathom brushing only once a day. I should floss more though. Once every blue moon isn’t exactly dentist recommended.

[–] [email protected] 16 points 2 days ago

I blame the moon for not being blue more often.

[–] [email protected] 21 points 3 days ago (3 children)

I trust approximately zero science about dental care, given the industry's track record.

[–] [email protected] 19 points 3 days ago (1 children)

You mean the elusive 5th dentist?

A systematic review by Cochrane is probably the most trustworthy source in medicine.

I wish in countries like mine things like electric toothbruses weren't like luxury items but things everyone could have. Got mine too late for my teeh but ever since I got it I no longer worry about dental plaque. Cavities and such things are hell on earth. Or, well, in your mouth.

[–] [email protected] 18 points 3 days ago (1 children)

I mean, as they kind of point out in the article, this doesn't actually say terribly much. I've always had the impression that electric toothbrushes are great for scrubbing off the plaque on the big surfaces of your teeth, while they're probably worse at reaching all the weird little angles of your teeth. This could result in 20% less plaque in total, while not removing it from where it lingers around and causes cavities. At the same time, if you also floss regularly, maybe you've got your weird little angles covered differently already. It depends on quite a few factors, for which a meta study like this can hardly do justice...

Are they equally more effective at removing gums?

[–] [email protected] 11 points 3 days ago (4 children)

I also sprinkle a little baking soda on my toothpaste to further remove plaque

[–] [email protected] 7 points 3 days ago (2 children)
[–] [email protected] 9 points 3 days ago (2 children)

I don't think that this removes more plaque, but it does neutralize the acids that they produce which damages teeth.

Baking soda can be used to brush teeth. There are brands of baking soda that have their own line of toothpastes that have baking soda as an ingredient.

[–] [email protected] 6 points 3 days ago (4 children)

What if we add baking soda on those toothpastes? Is it legal?

I was surprise it was this low. The wording of the study result is a bit different, it's not % of effectiveness, it's a % reduction in plaque.

The evidence produced shows benefits in using a powered toothbrush when compared with a manual toothbrush. There was an 11% reduction in plaque at one to three months of use, and a 21% reduction in plaque when assessed after three months of use. For gingivitis, there was a 6% reduction at one to three months of use and an 11% reduction when assessed after three months of use. The benefits of this for long-term dental health are unclear.
