How to brush your teeth in a truck without a sink

You are parked for the night, the nearest sink sits in a bathroom you would rather not stand in, and your teeth have not been touched since this morning.

Brushing inside the cab is ordinary, and most drivers who do it have worked the whole thing down to two minutes. Here is what that looks like.

Why the cab beats the truck stop bathroom

Truck stop bathrooms are the single biggest reason drivers skip brushing altogether. The sinks are shared, the air is bad, and standing at one with a brush in your mouth for two full minutes feels worse than going to bed unbrushed.

The cab has none of that. You control the water, the surface and how long you stand there. Nothing about a public sink cleans teeth better than a bottle of clean water does.

I brush my teeth in truckstop parking lots. Is this disgusting? I just don't want to inhale the billions of shit fumes in the bathroom while I brush my teeth. I'm also pretty sure toothpaste washes away quite easily

What you actually need in the cab

A full brushing routine needs three things: a brush, toothpaste and clean water. A sink is not one of them, and neither is a mirror.

Keep a sealed bottle of drinking water for your mouth and nothing else, so it never ends up holding coffee or washing hands. A wide cup makes rinsing the brush easier than tipping from the bottle.

Store the brush head up in a vented holder rather than a closed travel case. A sealed case keeps a wet brush wet, and a wet brush shut in the dark for ten hours starts to smell.

• clean water you keep only for your mouth
• a brush in a vented holder, not a sealed case
• toothpaste, with a spare tube in the bunk
• something to spit into, or a door you can open

Just need a cup and water... You can spit into a bottle or on the ground depending on how you feel about that. Also no one would bat an eyelash if you walked into a truck stop bathroom and brushed your teeth.

Where to spit, and why drivers argue about it

Spitting splits drivers more than any other part of this. Some keep a bottle in the cab, some open the door and spit on the ground, and each camp thinks the other has lost the plot.

A spit bottle works as long as you empty and rinse it daily. Toothpaste foam is mostly water and does not build up the way chewing tobacco does, so the bottle stays clean with almost no effort.

If the bottle is the part you cannot stomach, the door works fine. Toothpaste foam breaks down in the first rain and leaves nothing behind on the asphalt.

For real though. It's not like I'm rubbing my toothbrush on the counter and spitting on the floor. I'd rather be brushing my teeth at my house, but I'm not a local driver. Not keeping a spit bottle in my truck either.

Rinsing is the step worth skipping

Rinsing with a mouthful of water washes away the part of the toothpaste that was meant to stay on your teeth. Spit it out and leave the rest where it is.

The habit matters more in a truck than anywhere else, because water is the thing you have least of. Skipping the rinse saves the water and keeps the mineral on the enamel at the same time.

It feels wrong for about a week and then stops feeling like anything at all.

When I started otr, dentist told me no need for a sink to brush your teeth. Brush in the truck and spit into a bottle. Don’t worry too much about rinsing cause the fluoride in toothpaste is good for teeth. The bottle doesn’t stink like a dip spitter. Better than brushing in a public restroom with people shitting.

Keeping your mouth comfortable between stops

Long stretches between stops are when the mouth dries out, and a dry mouth gets worse by the hour. Cab air, heater air and talking on the radio all pull moisture out of it.

CariSpray is an alcohol-free, fluoride-free nano-hydroxyapatite oral spray built for exactly this moment: a few seconds, no rinsing, no sink, and nano-hydroxyapatite left sitting on the enamel afterwards. It fits a door pocket and works while the truck is moving.

Plain water helps as well, and it is the cheapest thing in the truck. Sipping through the day does more for a dry mouth than anything you do at the end of it.

The overnight routine that takes two minutes

Parked for the night is when the full routine earns its keep, because whatever you leave on your teeth sits there for eight hours. Brush, floss if you can manage it, and skip the rinse.

Floss picks are easier in a bunk than string and can be done lying down. Nobody is watching.

Then the brush goes head up, the bottle gets emptied, and that is the whole thing.

Common questions

Is it disgusting to brush your teeth in a truck stop parking lot?

No. Toothpaste foam is water, detergent and a small amount of mineral, and it washes away in the first rain. Drivers who brush in the lot are usually taking their teeth more seriously than average, not less.

Where do you spit if you do not want a spit bottle?

Out of the door onto the ground, or into a disposable cup you bin at the next stop. A bottle is the tidiest option in a cab you also sleep in, but it is one choice among several.

How much water do you need to brush your teeth?

Very little. A dry brush with toothpaste still removes plaque, and water mostly makes the whole thing feel normal. A quarter of a cup covers wetting the brush and rinsing it afterwards.

How do you keep a toothbrush clean on the road?

Let it dry. Store it head up in a holder with air holes rather than a sealed travel case, and keep it somewhere it cannot get knocked onto the cab floor.

Does skipping the rinse really make a difference?

Yes. Rinsing washes off most of what the toothpaste left behind. Spitting and walking away is the easiest single improvement to a routine that is otherwise fine.

Start with the water bottle. Buy one you keep only for your mouth, put it in the door pocket, and the rest of the routine builds itself around it.

The cab is a cleaner place to brush than any truck stop bathroom and always has been. The only thing standing between most drivers and a two-minute routine is deciding where the spit goes.
