Reunited Couple Kanye West and Bianca Censori Sue His Dentist for Malpractice, Providing Nitrous Oxide

Kanye West and his wife, Bianca Censori, are back together as a couple after an apparent split, their publicist confirmed to The Hollywood Reporter, and are preparing to sue the rap mogul’s former dentist for medical malpractice by supplying him with nitrous oxide and the intravenous anesthetic and sedative propofol, fraudulent billing, and multiple other alleged crimes.

In a formal notice of intent to initiate litigation sent to Dr. Thomas Connelly from Golden Law on Wednesday and signed by Andrew Cherkasky, the law firm’s president, the dentist’s alleged malpractice involving West is outlined in detail. Ye was a patient of Connelly starting in 2024 through earlier this year. During that time, he underwent various cosmetic procedures, including the placement of specialized prosthodontic work, a custom titanium crown and other cosmetic treatments. Connelly allegedly supplied the rapper with nitrous oxide and encouraged unsupervised self-administration while ignoring clear adverse neurological and behavioral signs apparent in the patient, the letter states. 

“Evidence shows that during the time Ye was under your care, you engaged in numerous inappropriate and dangerous practices that were far outside the bounds of any legitimate medical purpose or standard of care,” the letter states. “These actions were not isolated incidents but rather part of a pattern of improper conduct by you from 2024 through 2025 while Ye was your patient. Ms. Censori, as Ye’s spouse, was a witness to and impacted by many of these events (some of which took place at their shared residence).”

Connelly’s website touts him as a pioneer in luxury cosmetic dentistry for men, stating that “the world’s most influential men trust Dr. Thomas Connelly to craft their signature smiles. Designed for high-profile men, athletes, and those who demand the best.” He offers his services out of Beverly Hills, Manhattan offices and by appointment anywhere. A message sent by THR to his practice asking for a comment on Thursday did not harder an immediate response. 

West, who was diagnosed with bipolar disorder in 2016, displayed behavior that was erratic before and during the period when he was in Connelly’s care, but in those months, he did make several bizarre public statements and go on social media tirades, where he at one point praised Adolf Hitler and denounced the #MeToo movement. West also purchased local advertising during Super Bowl LIX, in which he appeared for his fashion and shoe brand, Yeezy, that aired toward the end of the game. In the spot, West was shown lying down at the dentist, shooting the spot on an iPhone front-facing camera, with sunglasses on.

“I spent, like, all the money for the commercial on these new teeth,” the rapper said, showing off his diamond-encrusted teeth. “Once again, I had to shoot it on the iPhone. Um … Um … Go to Yeezy.com.” 

The following day, the e-commerce section for Yeezy.com contained a single item — a black t-shirt emblazoned with a red swastika. The T-shirt is labeled on Kanye’s website as ‘HH-01,’ which is code for Heil Hitler.

In April 2025, West rapped in a new song titled “Bianca” that Censori had left him after his Twitter tirade that followed the Grammys, where the couple grabbed headlines after they unveiled Censori’s near-nude look on the red carpet. Yet the couple has been spotted together in Spain in recent days and on Thursday morning, their rep, Milo Yiannopoulos, confirmed to THR that the couple remains married and has reconciled.

Connelly is accused of a bevy of misdeeds in the letter, including instructing West on how to self-administer nitrous oxide without any medical supervision or safeguards. The dentist is accused of providing the rapper with tanks, masks, and other equipment and instructions on how to administer the “laughing gas” himself. The firm writes that the dentist “went so far as to deliver large ‘surgical-size’ nitrous oxide tanks to Ye’s residence (including the residence he shared with Ms. Censori), effectively enabling and encouraging him to inhale nitrous oxide outside of any medical setting.”

The letter noted that Connelly allowed this to carry on as West showed symptoms of neurological and behavioral distress. This can include confusion, memory lapses, incoherence, unpredictable changes in mood, impaired motor function, and other cognitive and behavioral problems, the letter states. It also notes that Connelly wrote apologies for his actions.

“On multiple occasions, you acknowledged in writing that your treatment of Ye was improper,”  the attorney’s letter to Connelly states. “In various communications (including text message exchanges and/or emails), you apologized to Ye and Ms. Censori and admitted that you had made mistakes in your treatment decisions.”

The letter also notes that Connelly extracted “exorbitant payments” from West for his services, to the tune of $50,000 per month, and alleges “cumulatively reaching into the hundreds of thousands of dollars.” 

In addition to the stream of nitrous oxide, Connelly allegedly supplied to West, he is accused of administering the drug propofol on multiple occasions in non-medical settings. One alleged incident took place at a hotel in Las Vegas, according to the letter, and another saw the dentist administer the drug, then discharge West from his care prior to verifying his state of mind. 

“As a result, in this instance, Ye suffered extreme mental and physical distress leading to urgent medical care,” the letter states. “In another instance, evidence suggests additional improper usage of propofol or similar controlled substances when Ye had diminished capacity and was not aware of or capable of knowingly consent for the usage of this substance due.”

Connelly is finally accused of reckless abandonment of West as his patient, failing to provide follow-up medical care, detoxification, or any referral as the mogul was in the depths of nitrous oxide dependency and suffering neurological damage.

In August, the issue of West’s dependency on the laughing gas was addressed by Yiannopoulos, who alleged that Connelly was intent on “[diminishing] Ye’s mental faculties so that Connelly and his business associates could extract millions of dollars from him,” as he wrote on X, denouncing the dentist. He also posted an affidavit he’d filed to the California Dental Board that week in early August, claiming Connelly had installed Ye’s permanent titanium prosthodontics earlier in 2024.

The former right-wing political pundit claimed in the affidavit that Connelly “charges rappers and cartel bosses for natural stones but puts vastly cheaper, lab-grown diamonds in their mouths instead.” He also asserted that a staffer at Yeezy saw the nitrous tanks brought to Censori’s apartment; in the end, five Yeezy staffers photographed the home nitrous installation. Connelly later claimed that the tanks were, in fact, empty. At the time, a rep for Connelly said that Yiannopoulos’s memory of events was “not only factually incorrect but also intentionally misleading,” and that he intended to damage Connelly’s reputation. 

Yiannopoulos had also posted a text message between himself, West and Connelly in which the dentist agreed to deliver tanks of the gas to the Chateau Marmont in L.A. as the West’s on-off publicist protested, listing some of the dangerous long-term damage of prolonged use of the gas.
