Teeth

"Teeth" by 5 Seconds of Summer delves into the complexities of a toxic and volatile relationship. The lyrics portray a love that is simultaneously passionate and destructive, characterized by a constant push-and-pull dynamic. Lead vocalist Luke Hemmings has stated that the song reflects a tumultuous and trying time in his own relationship. The central theme is the duality of a partner who can be both incredibly loving and dangerously hurtful. This is captured in the line, "Fight so dirty, but your love so sweet / Talk so pretty, but your heart got teeth." The song explores the addictive nature of this kind of love, where the highs are euphoric, but the lows are perilous, creating a cycle of emotional whiplash for the narrator.

The song chronicles the tumultuous and volatile nature of a deeply passionate yet destructive relationship. The narrator describes a lover who is a source of both intense comfort and extreme unpredictability. One moment, they are the only source of warmth and something to hold onto, the next, a complete stranger who evokes fear and uncertainty. This duality is a constant push and pull; the lover might push the narrator away only to desperately beg them to return. This confusing dynamic is a core theme, highlighting a relationship teetering on the edge of love and a desire for something akin to mutual destruction.

The cycle of hurt and reconciliation is a recurring pattern. The lover will apologize in the morning for their harsh actions, and these apologies, despite being built on lies, have an intoxicating effect on the narrator, described as giving him 'butterflies'. There's a dangerous allure in the way his partner looks at him, a look that makes him question his very survival within this love affair. The chorus powerfully summarizes this conflict: the relationship is a dirty fight, yet the love is incredibly sweet. The partner’s words are beautiful and seductive, but their heart is predatory, having 'teeth'. This 'late-night devil' has a physical and emotional hold on the narrator that he cannot, and perhaps will not, ever break free from.

The internal conflict of the narrator deepens as he contemplates the future. Some days, he envisions a life with this person, seeing them as his wife. However, this beautiful image is quickly shattered when their unpredictable nature takes over, transforming them into an unrecognizable and hostile person who once again pushes him away. The bridge of the song paints a stark, visceral image of the aftermath of their conflicts: 'Blood on my shirt, rose in my hand'. This suggests a simultaneous experience of pain and romance, a perfect metaphor for the entire relationship. He feels like his partner looks at him as if he's a stranger, emphasizing the emotional distance and the loss of identity he experiences within this chaotic bond. Despite the turmoil, the raw, physical, and emotional addiction remains, an unbreakable cycle of pleasure and pain that he is perpetually caught in.

"Teeth" was released on August 21, 2019, as the second single from 5 Seconds of Summer's fourth studio album, CALM. It was written by band members Luke Hemmings and Ashton Irwin in collaboration with Ali Tamposi, Ryan Tedder, Andrew Watt, and Louis Bell. The production was handled by Watt and Bell. Luke Hemmings mentioned that the song emerged after a period of intense writing where the band aimed to evolve their sound beyond their previous work on the album Youngblood. The song features a guest appearance by legendary guitarist Tom Morello of Rage Against the Machine, who contributes his signature guitar sounds throughout the track. The track's instrumental also contains a sample from an unreleased song by the late rapper Juice Wrld titled "So What". "Teeth" was also included on the soundtrack for the third season of the Netflix series 13 Reasons Why.

The song's rhythm is a key component of its intense and driving feel. It features a steady, pulsating beat with a prominent bass line that creates a sense of urgency and relentless forward motion. The tempo is moderate but feels energized due to the heavy percussion and industrial elements. The song is written in the key of D♯ Minor. The rhyme scheme in the verses is somewhat loose, following a pattern that prioritizes emotional delivery over strict structure. For example, in the first verse, 'know' and 'cold' create a rhyme, as do 'bed' and 'dead'. The pre-chorus follows an AABB rhyme scheme ('apologize'/'butterflies', 'eyes'/'alive'). The chorus is structured with rhyming couplets ('sweet'/'teeth', 'me'/'go'). This combination of free and structured rhyme contributes to the song's dynamic and unpredictable nature, mirroring the lyrical themes of chaos and control.

Musically, "Teeth" marks a significant stylistic shift for 5 Seconds of Summer, embracing a darker, more industrial sound. The song is built upon a prominent, driving bassline, heavy percussion, and distorted electronic sounds. The inclusion of Tom Morello's distinctive guitar work, characterized by techniques like whammy pedal stabs and toggle-switching, adds a layer of aggressive, rock-infused texture. Lead vocalist Luke Hemmings employs a dynamic vocal delivery, shifting from restrained falsetto in the verses to powerful, raw belts in the chorus, conveying a wide range of emotions. Lyrically, the song uses stark juxtapositions to create tension, such as "fight so dirty, but your love so sweet." The narrative voice is first-person, offering an intimate and raw perspective on the emotional turmoil. The repetition of the chorus and the phrase "never, never, never ever let go" acts as a hook while reinforcing the theme of inescapable attachment.

"Teeth" achieved significant cultural recognition and was praised for its darker, more mature sound, representing a stylistic evolution for 5 Seconds of Summer. The song was prominently featured on the soundtrack for the third season of the popular Netflix series 13 Reasons Why, which exposed it to a wider audience. It was also used as the official theme song for the WWE Survivor Series event in 2019. The track received critical acclaim and won Song of the Year at the 2020 ARIA Music Awards, and was nominated for the same award at the APRA Music Awards of 2020. The music video, directed by Thibaut Duverneix, is known for its dark and creepy aesthetic, depicting the band members undergoing a harrowing psychological experiment, further cementing the song's unsettling tone.

The central metaphor in the song is the concept of a "heart having teeth." This imagery powerfully conveys the idea of a love that is deceptive and dangerous. While the partner's words may be sweet and alluring, their true nature is predatory and capable of inflicting deep emotional pain. The 'teeth' symbolize the sharp, biting, and raw inner turmoil and the potential for hurt that lies beneath a beautiful exterior. The recurring phrase "late night devil" is another key metaphor, personifying the partner's seductive yet malevolent influence, particularly in moments of intimacy. The imagery of "blood on my shirt, rose in my hand" in the bridge symbolizes the juxtaposition of pain and romance that defines the relationship; even in the aftermath of a fight, a gesture of love is present, highlighting the confusing and inseparable nature of their love and conflict.

The most significant recurring motif in "Teeth" is the lyrical contrast between sweetness and violence, love and pain. This is most explicitly stated in the chorus: "Fight so dirty, but your love so sweet / Talk so pretty, but your heart got teeth." This phrase is repeated multiple times, becoming the central hook and thematic anchor of the song. Another recurring lyrical element is the push-and-pull dynamic, expressed in lines like "Push me away, push me away, then beg me to stay." The plea "never, never, never ever let go" is also repeated, emphasizing the narrator's deep-seated, almost desperate, attachment despite the toxic nature of the relationship. Musically, the driving bassline serves as a recurring motif that propels the song forward and establishes its dark, menacing tone from the very beginning.
