Teeth & Tongue released four albums, Monobasic (November 2008), Tambourine (April 2011), Grids (March 2014) and Give Up on Your Health (September 2016), before disbanding early in 2017.

Teeth & Tongue were formed in Melbourne in 2007 by Jessica Cornelius (ex-Moscow Schoolboy) on lead vocals, keyboards and guitar, as a vehicle for her song-writing.

"[1] Teeth and Tongue's debut album, Monobasic, was issued in November 2008 via Inertia Records/Crystal Chain Records with Cornelius co-producing with Casey Rice.

Teeth & Tongue, with the line-up of Cornelius, Steve Masterson, Marc Reguiro-Mckelvie and "Patto" Millman, were chosen as Triple J's radio programme Home & Hosed's Next Crop artist in November 2009.

[2] Steph Hughes of that programme explained, "Her latest songwriting output has seen the group remaining true to initial brooding sensibilities – with an added special sauce.

Kat Mahina of The AU Review caught a live gig in July 2011, where, "Cornelius was in fine form and visibly less nervous than she was at her own album launch a few weeks ago.

[6] In March 2012 Teeth & Tongue undertook a solo North American tour, including performances at the SXSW festival and New York's Piano's.

She’s got a real knack for setting the scene in her songwriting, and has a novelist’s gift for conveying the kind of minute details in her lyrics that really put the listener in her head space.

Teeth & Tongue's third album, Grids, was released in March 2014, with a line-up of Cornelius and Reguiro-Mckelvie joined in the recording studio by Damian Sullivan on bass guitar and synthesiser.

Jake Cleland, of music website thevine.com.au, observed, "equal parts piano balladry, electronic squall and guitar buzz, but its most distinct component is Cornelius's voice.

One moment a David Bowie yawp, the next a Kate Bush howl, another soulful crooning, and occasionally joining herself in choirs both weeping and thunderous, Grids features some of her most adventurous vocal work to date.

"[15] The second single, and video from the album, "Good Man", premiered on Pages Digital,[16] A writer for Australian Independent Record Labels Association (AIR) described it as "jawdropping" and "breathtaking" and explained, "We've never heard a song like it before.

[18] During 2014, Teeth & Tongue had expanded to a five-piece band to recreate the Grids album for live shows, Cornelius, Reguiro-Mckelvie and Sullivan were joined by James Harvey on drums and Jade McInally on backing vocals, keyboards and percussion.

Teeth & Tongue has supported J Mascis, Vance Joy, EMA, The Drones, The Mountain Goats, The Dodos, Laura Marling, Courtney Barnett, Juana Molina, Sons and Daughters (band), Jack Ladder, Adalita and Dan Kelly in Australia.
