What with the multiple recommendations for a water pick in the comments, lemme drop some aggregated info I’ve gathered about them after asking multiple dentists and hygienists over the last few years while sitting around waiting for various things.
They’re great for what they are, but they aren’t as great as people think they are.
They do definitely work, no doubts, every single one that I talked about them with said that they’ll get the job done.
The problem is that they have a higher learning curve than you’d think, and that means they can cause more trouble than they fix.
See, you’re using the water pressure at an angle because of how you have to hold the pick and move it. The angle that you’ll likely use them at is the wrong one, and this means you are probably going to be shooting the plaque and debris the pick dislodges under your gums.
Obviously, that is not a good thing.
You can definitely learn how to avoid doing that with a bit of research, but most people don’t do that bare minimum research, they just start spraying and then wonder why their gums are bleeding and sore.
So, if you want to invest in a water pick (and tbh, saving the money to pay for a yearly cleaning would be better), make sure you take the time to use it properly. But, they aren’t better than floss at all, so unless you have some reason you can’t floss, why spend the money?
Point one is key! I will add to it, floss of any sort is great. And for my mouth 'interdental brushes' do just a little bit more, so the combination has become a key part of my dental routine.
Most importantly: Brush at least once, better twice a day. No exceptions ever. Make it part of your daily morning or evening rituals. It takes about a day for plaque to harden and then you can no longer brush it away. Don’t ever let it get to that.
If you can afford one, get an electric toothbrush.
Be gentle with the brush. All you need is a very soft scrubbing. Pressure can damage your teeth and gums.
Chewing gum can reduce acids and help remineralize your enamel after eating. Sugar free is better, but afaik even gum with sugar has a net positive effect if you chew it long enough after the sugar has dissolved.
Try to avoid getting into a routine that leaves out spots when brushing. Personally, I switch hands every day and once or twice a week I use a non-electric brush.
If you want to optimize this: those tablets that the dentist uses to stain plaque to check where you missed a spot are cheap, you don’t necessarily need a dentist for that if you can’t afford one.
Floss and use interdental brushes regularly. Use mouthwash every now and then, and at the first sign of gum inflammation. Preferably one without alcohol, because that seems to increase the risk of cancer.
If you can’t afford professional tooth cleaning, try asking for calculus removal, if you have any. Here in Germany that’s ~15€ instead of ~100€. Once it’s gone prevent it from building up again (see above).
If you have cavities, try to get rid of them as early as possible. Maybe there are some charity or teaching clinics. Cavities only ever get more expensive in the long run. And it is much easier to maintain an infection free mouth than to constantly fight to keep the decay from spreading.
A toothpaste that restores your enamel. It’s prescription in the US but you can get Apagard Premio off Amazon.
It’s probably a good idea to get some extra fluoride since the Apagard doesn’t have any. I use purple Listerine, but I kinda hate it, so find something you like.
You should floss, which I’m shitty at, so I use a water pick a few times a week. All kinds of nasty crap comes out, even after brushing, so it’s gotta be better than nothing.
I use a Philips Sonicare toothbrush, no need to get the fancy ones, it’s mostly extra accessories. There are probably less expensive ultrasonic toothbrushes out there that work well… doing it twice a day manually is probably better for you than once a day with a fancy toothbrush.
Hang in there, clinical trials of a drug that regrows teeth are underway and the results are promising.
Disclaimer: This is not personal medical/dental advice, just my own understanding that I'm sharing.
Floss (or water pick) first, then mouthwash, then brush, then don't rinse.
Floss to open up the gums and knock loose anything stuck in between teeth.
Mouthwash to get rid of the solids and get a bit of fluoride in between teeth.
Brushing after mouthwash, because toothpaste typically has a much higher concentration of fluroide than mouthwash does.
And avoid rinsing after brushing so you don't wash away the residual fluoride from the toothpaste.
If you are truly struggling and need actual dental care, try searching for a local dental school near you. Many will take patients for cheap or free, with the caveat that a dental student will be performing the treatment.
Otherwise, brush at least twice a day and floss. Do not re-use strands of floss, like with those convenient plastic picks. You’ll just be transferring bacteria to each crevice after it’s been used.
Get a water pick (whatever it’s called) - I heard those are great but I don’t have one myself.
Shop around, you can frequently get discounts or cheaper rates if you tell them you're uninsured / self pay. I've had to do this during tough financial times.
There may also be some luxuries or other corners you can safely cut if you go over your budget with a fine toothed comb.
