Oral nicotine pouches, often found near convenience store checkout counters, are frequently advertised as a safe, tobacco-free alternative to cigarettes. However, dental professionals at the University of Utah School of Dentistry caution that being tobacco-free does not mean these products are risk-free.
Carter Bruett, DDS, a dentist at the University of Utah School of Dentistry, stated that because these products are relatively new, long-term studies do not yet exist. He noted that known risks include significant inflammation and tissue damage in the mouth, with many questions regarding overall health impacts remaining unanswered.
The mechanism of nicotine pouches involves placing a small pouch between the lip and the gum to allow nicotine to pass through oral tissues. Dr. Bruett explained that because the area between the cheek and gums contains many blood vessels, nicotine is absorbed efficiently and enters the bloodstream quickly.
This process can lead to localized tissue destruction and inflammation at the site of placement. Over time, this inflammation may result in gum irritation, gum recession, loss of healthy gum tissue, increased risk of tooth loss, and permanent changes to mouth tissues.
Research suggests that nicotine can directly damage fibroblasts, which are cells responsible for maintaining and repairing gum tissue and supporting tooth structures. As these cells are destroyed, the body loses its ability to regenerate those tissues.
Dentists have observed red, irritated gums in patients who regularly use nicotine pouches, as well as thick white patches. While researchers do not currently have enough evidence to determine if nicotine pouches directly cause oral cancer, they do know that chronic inflammation and cell damage can increase the risk for cancer development.
Dr. Bruett advised that individuals noticing persistent white areas, red areas, ulceration, or bleeding where a pouch is placed should be evaluated by a dental professional.
Beyond oral health, scientists are studying how high doses of nicotine in these pouches might affect cardiovascular risks, as nicotine can narrow blood vessels and increase heart workload. Other areas of ongoing research include the effects on the oral microbiome, saliva composition, blood pressure regulation, and digestive health.
Some early research indicates that users may experience gastrointestinal symptoms like bloating or stomach discomfort, though more studies are required to understand why. Health experts recommend that users inform both their dentists and primary care providers about their use of nicotine pouches.
