In China, a new trend is reshaping adult coping culture and it’s not herbal tea, meditation apps, or plush toys. It’s adult-sized pacifiers. Once the domain of babies, these silicone soothers have found a surprising audience among stressed-out grown-ups looking for calm, better sleep, or even help quitting smoking.Available on platforms like Taobao and JD.com for as little as 10 yuan ($1.40) and as much as 500 yuan ($70), they’re marketed with a wellness twist: stress relievers, sleep aids, even bite guards to prevent teeth grinding. Some users swear they help curb late-night snacking or silence a snoring partner. And they’re selling fast! According to South China Morning Post, top vendors are moving thousands every month.The phenomenon has exploded on Chinese social media. On Sina Weibo, hashtags related to “adult pacifiers” have racked up over 68 million views. Douyin (China’s TikTok) is packed with short videos of young people unboxing, testing, and explaining why they’ve embraced the trend. The most popular pacifiers measure 4.5 centimeters—nearly twice the size of those for infants—and are designed for adult mouths.For some, it’s about breaking a habit. A Douyin user credited the pacifier with stopping her constant snacking, claiming it even helped with weight loss. Another posted that it helped her finally quit smoking after years of failed attempts. Many describe the sensation as instantly calming, a tactile anchor in a chaotic day.Is This A Use Of Regression As A Coping Mechanism?Psychologists point to the “regression phenomenon” to explain why this works for some. When stress overwhelms, people may subconsciously revert to behaviors from an earlier, more secure stage of life. In infancy, sucking is a natural source of comfort and self-soothing. For adults, the pacifier becomes a symbolic return to a time without deadlines, bills, or complex emotional burdens.“It feels like the safety of childhood,” one office worker wrote in an online review. That feeling can be powerful—especially in high-pressure work environments where people struggle to find moments of rest.Is Any Medical Caution Needed?Not everyone is convinced this is harmless. Dentists like Tang Caomin warn that prolonged use can shift teeth, limit jaw movement, and cause temporomandibular joint (TMJ) issues. There’s also a risk of sleep disruption or choking if parts come loose during the night. Wang Xueling, director of stomatology at the Aerospace Center Hospital in Beijing, notes that while pacifiers can offer temporary emotional relief, they don’t address the underlying causes of stress.Psychologist Zhang Mo is more direct: “The real solution is not to treat yourself as a child, but to face the challenge directly.”This isn’t staying in China. On TikTok, American users have begun posting clips of themselves with adult pacifiers—in traffic, at work, or during intense moments of burnout. Some claim it helps with ADHD-related restlessness, while others admit it’s simply a private comfort they’ve used for years.A commenter averred to having used pacifiers for 23 years, and another dismissed worries about dental effect: "It hasn't moved my teeth, been using them for 4 years." Nevertheless, critics propose alternatives such as chewing gum or lollipops to meet the same oral fixation without risking dental damage.It's not just an object that the adult pacifier trend represents; it is what the object stands for. In the face of economic insecurity, social pressure, and constant digital overstimulation, small rituals that give control or comfort can become very attractive. For many, this has been a private rebellion against relentless productivity culture, reminding them that it's okay to need comfort-even if it looks unconventional.Why Adults Are Reaching for Pacifiers?The oral fixation and emotional regression psychology lies at the root of this phenomenon. Psychoanalytic theory has it that in the course of human development, the oral stage marks the earliest point. This is where sucking, eating, and all else related to the mouth takes precedence for comfort and bonding purposes. When adults experience stress beyond their coping ability, they may respond unconsciously by regressing to behaviors associated with this stage—behaviors that once consistently brought feelings of safety.In today's language, this is a type of "self-soothing." Similar to chewing on a pen cap, biting one's nails, or drinking from a straw, pacifier use involves sensory pathways that quiet the nervous system. The rhythmic, repetitive motion can relax breathing, decelerate heart rate, and generate an inconspicuous feedback loop that communicates relaxation to the brain.But there's an important difference between temporary relief and addiction. Whereas brief use may alleviate anxiety or cut addictive habits like smoking, heavy reliance on such aids can cover up underlying problems—long-term stress, sleep disorders, unresolved emotional trauma—that need more engaged solutions. Therapists warn that such behaviors are better understood as adjunctive coping strategies, not substitutes for solving core issues.That is, the pacifier can get you through a long commute or a stressful meeting. But it won't address the situation that's causing you to need one in the first place. The true test—and challenge—are in figuring out how to introduce some of that same sense of security into your life without resorting to a silicone substitute.
