Part of the joy of getting a new toothbrush is the ability to use the old one to clean hard-to-reach places, such as inside the mouth of a pet piranha. Brush your way to a beaming smile with today’s Groupon: for $14, you get two Justin Bieber singing toothbrushes from Brush Buddies (a $29.90 value).

The dental-hygiene heroes at Brush Buddies transform ho-hum teeth-brushing sessions into enamel-whitening extravaganzas with a signature line of fun, ergonomic toothbrushes designed to ensure kids polish their pearlies for at least 120 dentist-recommended seconds. Endorsed by dentists and screaming tweens around the country, each replaceable brush head sports soft DuPont bristles and a plastic sheathing that complements a thick handle graced with Justin Bieber’s dreamy doe eyes, floppy crop of hair, and incandescent halo. After pressing one of two buttons—one for both morning and evening brushes—cavity-crushers can enjoy Bieber’s cherubic croon for 120 seconds, the exact length of time dentists recommend for shining smile bones. Brushers can serenade bathroom-mirror reflections with the echoing sounds of Bieber’s “Baby” and “U Smile” from one brush, or whip out its counterpart to show off hygiene habits and subtly court secret crushes with midday brushes set to the tunes of “Love Me” and “Somebody to Love.”
