You be the judge: should my roommate stop brushing her teeth at the kitchen sink?

The Prosecution: Raquel

I can hear Gina brushing her teeth from my room—the swishing and spitting really gets to me. It’s a gut-level reaction.

We’ve lived together for two years now, after both of us went through breakups and needed a fresh start. Gina is fun and kind, but at home, her tooth-brushing habits drive me crazy. Sometimes she brushes her teeth in the kitchen sink if she’s in a rush to leave.

Gina has ADHD and is always multitasking. She’ll leave her keys in the door, which worries me, or misplace her toothbrush in the morning. I’ll come home and find it sitting on the kitchen counter after she’s used it. That grosses me out—the kitchen is for cooking, not spitting. It’s where we wash vegetables and rinse cups. I shouldn’t have to look down and see toothpaste foam sliding toward the drain.

In the bathroom, she has another bad habit: drinking straight from the tap while brushing. Not just once or twice—four or five times per session to rinse her mouth. She leans over, sucks water right from the faucet, swishes, and spits. I can hear the whole performance from my room, and it makes me cringe. Why not just use a cup?

I don’t know if her mouth touches the tap, and I don’t want to know. That’s the same tap I use to wash my face and fill my water bottle.

I don’t think I’m being overly sensitive. It’s about hygiene and respecting shared spaces. Brushing your teeth should stay at the bathroom sink, and the tap shouldn’t become a public drinking fountain.

Gina says she’ll try to stop, but every time I bring it up, she’s careful for about a week before slipping back into old habits. Living with someone who has ADHD can be challenging, but sometimes it feels like she uses it as an excuse. I’m not perfect either, but when someone asks me to change, I make an effort. Gina could try a little harder.

The Defence: Gina

Living with ADHD isn’t easy, and honestly, the kitchen isn’t some holy space reserved only for food.

Raquel is exaggerating and missing the bigger picture. Yes, I sometimes brush my teeth in the kitchen sink, drink from the tap, and leave my things around—but that’s just how my brain works. With ADHD, I get distracted easily.

In the morning, I’m often multitasking—brushing my teeth while putting on my shoes or making lunch. The kitchen sink has running water and a drain, just like the bathroom. It all goes to the same pipes. It’s not some sacred zone, like Raquel seems to think.

I rinse the sink afterward—I’m not leaving spit everywhere. And honestly, the kitchen sink probably gets cleaned more often than the bathroom one. I don’t do this every day, either. The only evidence is if I leave my toothbrush out, which I know I shouldn’t do, but sometimes I forget.

As for drinking from the tap—lots of people do it. I grew up doing it with my brother. To me, it’s normal to rinse your mouth that way. Using a cup every time feels like extra work. I don’t put my mouth right on the tap—I just lean in and catch the water. Raquel makes it sound like I’m lapping it up like a cat. I like to rinse thoroughly, so yes, I take a few sips. It might sound like a lot, but it leaves my teeth feeling clean.

Bathrooms aren’t sterile labs. Germs are everywhere. Unless Raquel is disinfecting the tap every day, we’re both exposed to the same things.We all come into contact with germs in the bathroom. Living with ADHD is challenging. I could point out things Raquel does that bother me—everyone has habits that can be annoying, but I accept them because we live together. I can’t promise I’ll change. I’ve tried to stop walking around while brushing my teeth, but I keep forgetting.

The Guardian readers’ panel weighs in:

Should Gina take Raquel’s complaints more seriously?

Raquel should understand that sharing a home means they’re already exposed to each other’s germs. Drinking from the tap isn’t unhygienic—even if Gina put her mouth on it—because the water flows from inside the pipe. But it seems like Gina is using her ADHD as an excuse. She should respect Raquel’s feelings and try to adjust her behavior. Also, rinsing after brushing washes away fluoride—it’s better to just spit.

Mark, 64

Raquel’s issue seems to go beyond toothbrushing. If Gina changes, Raquel will likely find something else to complain about. It sounds like this living arrangement has run its course.

Caroline, 60

Gina is right that living together requires compromise, but she’s refusing to respect a reasonable request from her roommate. This is less about hygiene and more about respecting each other’s boundaries.

Molly, 26

Drinking from the tap is fine as long as there’s no direct mouth contact. But leaving a toothbrush on the kitchen sink is just gross. I don’t have ADHD, but it feels like Gina is using it as an excuse.

Thomas, 30

If Raquel can learn to work with Gina’s ADHD, Gina should also show some willingness to adapt. Not rinsing after brushing would help Gina get the full benefit of her toothpaste and could solve two issues at once.
