‘Inappropriate and dangerous practices’: Kanye West and Bianca Censori sue dentist over alleged nitrous oxide abuse

Kanye West and his wife, Bianca Censori, have started legal proceedings against Dr. Thomas Connelly, a cosmetic dentist based in Beverly Hills. They are accusing him of medical malpractice, fraud, and other serious wrongdoing.

The lawsuit, which was formally announced with a notice of intent to sue, claims that Connelly engaged in a series of inappropriate and dangerous actions during West’s treatment between 2024 and early 2025, according to TMZ. The main accusations focus on Connelly allegedly giving West excessive amounts of nitrous oxide, also known as “laughing gas,” for reasons not related to medical treatment while also encouraging him to use it on his own without supervision.

The legal filing further states that Connelly ignored clear signs of West’s declining neurological and behavioral health, which the lawsuit says was directly caused by nitrous oxide abuse. The notice explains that Connelly not only provided West with large amounts of nitrous oxide, including big tanks delivered to West’s home, where he lived with Censori, but also gave him the equipment and instructions to use it himself.

This allegedly happened even though Connelly noticed and acknowledged symptoms of neurological and behavioral problems in West, such as confusion, memory loss, and sudden mood changes. The lawsuit argues that these actions show a complete disregard for standard medical practices and patient safety. Censori, as West’s wife and someone who witnessed many of these alleged incidents, is also listed as a plaintiff, emphasizing how Connelly’s actions affected both of their lives.

In addition to the nitrous oxide allegations, the lawsuit claims that Connelly gave West propofol, a strong anesthetic, in non-medical settings on multiple occasions. One of these instances supposedly took place at a Las Vegas hotel. Another incident allegedly involved Connelly giving West propofol and then sending him away without checking his mental or physical condition, which the legal documents say led to “extreme mental and physical distress” that required emergency medical care.

The lawsuit also accuses Connelly of abandoning West as a patient in a reckless manner, failing to provide necessary follow-up care, detoxification, or referrals, even though West appeared to be dependent on nitrous oxide and suffering from neurological damage as a result.

The financial side of the accusations is also significant. The notice claims that Connelly charged extremely high fees for his services, reportedly billing West $50,000 per month, adding up to hundreds of thousands of dollars over the course of the treatment. This is presented as part of a larger pattern of exploitative behavior, suggesting that Connelly’s actions were motivated by money rather than genuine patient care.

These allegations match previous claims made by Milo Yiannopoulos, West’s former publicist, who had earlier accused Connelly of unethical behavior. Yiannopoulos previously said that Connelly was intentionally weakening West’s mental state to take advantage of him financially, even claiming that Connelly used cheaper, lab-created diamonds instead of natural ones in West’s dental work. He also said that Connelly provided nitrous oxide to West for financial gain.

While Connelly denied Yiannopoulos’s statements in the past, the current lawsuit presents what West and Censori believe is supporting evidence. The seriousness of the lawsuit is heightened by the fact that West had previously been diagnosed with bipolar disorder, a condition that, according to the plaintiffs, was made worse by Connelly’s alleged actions.
