"Teethsucker (Yea3x)" was released as the lead single from Lethal. The song's music video was premiered by Pitchfork at the time of the album's announcement. Rico Nasty stated that the song was the first written for the album and marked her first collaboration with Imad Royal, who served as the album's executive producer. She said that the song was intended to introduce the album's new creative era.
Stereoboard described the track as striking a balance between rap and electro-rock, while Beats Per Minute called it a "distorted electro-punk banger." The song has been described as a heavy, riff-driven rap rock track, while Billboard called it a "rambunctious rock-rap" track. According to HotNewHipHop, the song features a guitar-driven instrumental with loud 808s, along with Rico Nasty's exaggerated vocal delivery, which the publication said evokes pop-punk influences.
The song received a positive response from HotNewHipHop, which described it as a strong introduction to Lethal. The lyrics were described as focused on self-assertion, with the reviewer attributing their effectiveness to her charisma. Billboard highlighted Rico Nasty's performance, noting that she navigates the raucous instrumental from Rayman on the Beat and Imad Royal with ease, and suggested that the single could represent a moment for her to reach a wider mainstream audience.
