Okay, So I Gave In to the Purple Foam Hype
Listen, my TikTok “For You” page was absolutely bombarded with this stuff. Every other video was someone squeezing out this bizarre, vibrant purple paste, looking shocked when it foamed up. I finally cracked after the third coffee stain incident on my favorite mug—and, you know, my teeth. I ordered the West&Month Purple Mousse Toothpaste, fully expecting a gimmick. I gotta say, I was wrong. Mostly.
First Impressions: It’s Weird (In a Good Way?)
Honestly, the texture threw me off. It’s not a gel or a cream; it’s a proper mousse. Like, whipped cream for your teeth. The purple is intense—think grape soda vibes. The smell is mild, vaguely minty but not that aggressive, chemical blast you get from some brands. It feels…gentle? Which concerned me at first because my old toothpaste felt like it was sandblasting my enamel. Here’s the thing: it doesn’t foam up a crazy amount in your mouth. It’s a soft, dense foam that feels like it’s actually coating everything.
The Stain Test: Coffee vs. Purple Mousse
My main goal was those pesky surface stains. I drink an ungodly amount of coffee, and my morning scroll is usually paired with a giant mug of it. After about two weeks of using this twice a day, I actually noticed a difference. My teeth looked…brighter? Not “bleached white magazine cover” bright, but like they’d returned to their natural, off-white color instead of the sad, dingy yellow they were heading towards. It’s a subtle win, but a win. I think the mild abrasion from the mousse action works without being harsh.
Where It Shines (And Where It Doesn’t)
The breath freshness is legit. It’s not the “minty for 5 minutes then gone” kind. It’s a clean feeling that lasts. I don’t feel self-conscious after lunch, which is a big deal for someone who loves garlic as much as I do. Now, for the downside, because nothing’s perfect. It contains sodium lauryl sulfate (SLS). My mouth isn’t super sensitive to it, but if you get canker sores easily, you might want to be aware. Also, at nearly $27 a tube, it’s an investment. I made a quick comparison chart for you lazy folks:
| Feature | West&Month Purple Mousse | My Old Drugstore Paste |
|---|---|---|
| Price | $26.99 | $4.99 |
| Main Thing | Sodium Lauryl Sulfate, Sorbitol (Mousse base) | Abrasives, Strong Detergents |
| Texture/Feel | Soft, coating purple mousse | Gritty paste, intense foaming |
| Effect on Stains | Gentle, gradual brightening | Harsh, minimal effect |
Final Verdict: Is It Worth Your Money?
Can you believe this? I’m actually going to repurchase it. I was binge-watching Netflix last night and caught myself smiling at a funny scene, and I thought, “Huh, my teeth don’t look bad.” That’s the real review right there. If you’re looking for a dramatic whitening treatment, this isn’t it. But if you want a gentle, effective daily cleanser that tackles surface stains and keeps your breath fresh without making your mouth feel like it went through a chemical wash, the Purple Mousse is a solid choice. The price is the biggest hurdle. But for me, the gentle effectiveness and that lasting clean feeling make it worth it as a treat.
Just maybe hide it from your roommate or partner so they don’t use half the tube in a week. Not that I’m speaking from experience or anything.
