Just apply a pea-sized amount to both sides of the brush head. Since regular toothpaste is thicker, consider adding a little hot water to help it foam up before you start brushing. For a thorough clean, you might want to use a longer brushing cycle. After brushing, don’t forget to rinse your brush head well. This approach ensures your brushing routine is as effective and enjoyable as possible!

Ruby X. ★★★★★

The hot water trick works better than I expected—the foam gets so much fluffier and reaches everywhere. Been using it for a week now and my teeth feel noticeably slicker and cleaner after each brush.

Victoria ★★★★★

I was skeptical about the pea-sized amount but it really does cover both sides of the brush head without wasting anything. Adding a little hot water to thin out my regular toothpaste worked perfectly and created a nice foam for a deeper clean.

Claire ★★★★★

The hot-water trick really works—it foams up nicely and gets every corner of my mouth feeling fresh. I’ve been using it for a week and the brush head comes out noticeably cleaner than with my old paste.
