Yes, labret piercings can and frequently do damage teeth. The flat metal disc that sits against the inside of your lower lip rubs against your teeth and gums every time you talk, eat, or move your mouth. Studies show that people with lip piercings are about four times more likely to have tooth damage than people without them. Roughly one-third of teeth adjacent to a labret piercing develop abnormal wear, chipping, or cracking over time.
How a Labret Piercing Wears Down Teeth
A standard labret stud has a flat back plate that rests flush against the inside of your lower lip, directly in front of your lower central incisors. That disc makes constant, low-grade contact with your enamel. Talking, chewing, even just pressing your lips together pushes the metal into the same teeth thousands of times a day. Over months and years, this repeated friction grinds away enamel in patterns that wouldn’t occur naturally.
The damage shows up in several forms. Enamel can develop hairline fissures, visible chips, or broad areas of flattened wear. In clinical studies, tooth fractures or fissures appeared in about 20% of people with oral piercings, and structural damage to enamel was documented in roughly 13% of cases. Because enamel doesn’t regenerate, every chip and scratch is permanent.
Gum Recession Is the Bigger Concern
Chipped enamel gets the most attention, but gum recession is actually more common and potentially more serious. One study found gum recession on teeth facing the labret disc in 68% of pierced individuals, compared to just 22% of people without piercings. That’s not minor thinning. Nearly 19% of the pierced group had moderate to severe recession that exposed the tooth root, a level of damage that wasn’t seen at all in the unpierced group.
When gums recede, the softer root surface underneath becomes exposed. Root surfaces are far more vulnerable to decay than enamel, and once gum tissue pulls back, it doesn’t grow back on its own. Severe recession can lead to tooth sensitivity, increased cavity risk, and eventually tooth loosening if the supporting bone also deteriorates. The contact point between the labret disc and the gum line is the primary driver: the jewelry creates a persistent pressure point that gradually pushes the tissue away from the tooth.
Jewelry Material Makes a Difference
Not all labret materials cause the same amount of damage, though none are risk-free. Research comparing titanium and stainless steel jewelry found that stainless steel caused tooth chipping in about 43% of wearers, while titanium chipped teeth in about 36%. Titanium, however, was worse for gums, causing recession in nearly 53% of patients compared to about 24% for stainless steel. Neither material comes out looking good.
Bioplast, a flexible biocompatible plastic, is softer than any metal and produces less friction against enamel and gum tissue. It won’t eliminate the risk entirely since any object resting against your teeth creates wear over time, but the softer surface reduces the force of each contact. If you already have a labret piercing and want to minimize ongoing damage, switching to a Bioplast flat back is one of the more practical steps you can take.
Why Downsizing Matters
When a labret is first pierced, the jewelry is intentionally longer than needed to accommodate swelling. That extra length means more metal sitting inside your mouth, more movement, and more contact with teeth and gums. Once swelling subsides, typically around four to six weeks, the jewelry should be swapped for a shorter post. Lip piercings often need a second downsize around two to three months.
Skipping or delaying this step is one of the easiest ways to accelerate dental damage. A longer post shifts and rocks more freely, hitting teeth at angles a properly fitted post wouldn’t reach. It also increases the chances of you unconsciously biting down on the disc or playing with it against your teeth, a habit that dramatically increases chipping risk.
Vertical Labrets and Placement Variations
A standard labret piercing enters through the skin below the lower lip and exits inside the mouth, placing a flat disc directly against the teeth. A vertical labret, by contrast, enters at the base of the lower lip and exits through the lip’s top edge, with both ends of the jewelry sitting on the outer surface of the lip. Because no jewelry component sits inside the mouth, a vertical labret carries virtually no risk of tooth or gum damage.
For standard labrets, placement height and angle also matter. A piercing positioned higher on the lip places the disc closer to the gum line, increasing recession risk. A lower placement may reduce gum contact but still allows the disc to rub against enamel. There’s no “safe” standard labret position that avoids dental contact altogether, since the disc inevitably rests against the front surface of the lower teeth.
What Dentists Recommend
The American Dental Association advises against all oral and perioral piercings, stating that the complications outweigh any benefit. Their listed risks include chipped teeth, gum recession, infection, scarring, and in rare cases, jewelry that becomes embedded in tissue and requires surgical removal.
If you already have a labret piercing and plan to keep it, a few steps can reduce (but not eliminate) the damage. Keep the post as short as possible once healed. Choose Bioplast or another flexible material over metal. Avoid clicking the disc against your teeth or playing with the jewelry. And get regular dental checkups so your dentist can monitor for recession or enamel changes before they become severe. If recession is already visible, removing the piercing is the most effective way to stop it from progressing.
