A smiley piercing goes through the frenulum, the thin, web-like fold of tissue that connects the inside of your upper lip to your gum. With your mouth closed it is completely hidden. Smile wide enough to lift the lip and a small ring or bar appears, which is exactly the effect the name describes.
It is one of the quickest, least painful piercings available, and it also has one of the higher rejection rates of any common piercing. Both facts come from the same source: the tissue it sits in.
The anatomy question
The frenulum needs enough substance to hold jewelry through months of constant movement. Every time you talk, eat, smile or move your lips, this tissue flexes.
Some people have a well-developed frenulum with real depth to it. Others have a very thin, tight, or short one, and there simply is not enough tissue for jewelry to sit in without pressing directly against the gum or the lip from the moment it is placed. A piercer who examines you and declines is protecting you from a piercing that would likely reject within weeks regardless of care.
Pain
About 2 out of 10, among the mildest piercings anywhere on the body. The frenulum is thin with relatively few nerve endings, so the sensation is a brief, light pinch rather than anything sharp.
Why it rejects more than most
A smiley is not technically a surface piercing in the way an eyebrow is, but it shares the same underlying problem: thin, constantly moving tissue gives jewelry very little to anchor into. Add in that the frenulum flexes with essentially every use of your mouth, and the conditions are set for the body to gradually work the jewelry back out.
This is a known, common outcome rather than a sign anything was done incorrectly. Smaller, lighter jewelry and gentle handling reduce the risk, but they do not eliminate it. Go in understanding that a smiley may not be permanent, in the same way a dermal is not.
Healing
Four to eight weeks, quick, because the mouth has an excellent blood supply. The main task during this window is protecting the fragile, thin tissue from unnecessary flexing and contact rather than managing pain or swelling, both of which are minor here.
Downsize at two to four weeks, once the small amount of swelling has settled. On tissue this thin, any spare bar length is extra leverage working against you.
Aftercare
- Rinse with alcohol-free mouthwash or saline after every meal, every drink other than water, and after smoking.
- Avoid excessive talking, wide smiling or lip movement more than necessary in the first days, simply to reduce flexing of the fresh piercing.
- No kissing, sharing drinks or cutlery, or oral contact for the first couple of weeks.
- Do not flip, tug or play with the jewelry to show people. Every movement is one more chance for it to migrate.
Jewelry
Start with a small curved barbell or a small captive bead ring, 16 gauge, 6 to 8 mm, in ASTM F136 implant-grade titanium. Small and light is the whole strategy here: anything larger adds leverage that the thin tissue cannot resist, and anything that contacts the gum or teeth constantly causes its own problems.
See the material guide for why titanium is worth insisting on even for a piece this small.
Dental contact
The jewelry sits close to the upper front teeth and gum line. Over time, contact here can chip enamel or irritate the gum, the same risk that applies to tongue and lip piercings. Keep the jewelry small and flat, and mention the piercing to your dentist.
If it starts to reject
Watch for the jewelry sitting closer to the surface than it did, the tissue around it thinning, or the piece feeling looser or shifting position. If you notice any of this, see a piercer rather than waiting for it to fall out on its own; removing it in good time causes less disruption to the tissue than letting rejection run its course.
Frowny: the lower-lip equivalent
The same piercing done through the lower lip frenulum, connecting the inside of the bottom lip to the gum, is called a frowny. It behaves identically: minimal pain, fast healing, and the same elevated rejection rate for the same anatomical reason.
Cost
$30 to $50 for the piercing in a US studio, plus $20 to $50 for a small titanium bar or ring. It is one of the least expensive piercings available, reflecting how quick and straightforward it is to place.
Frequently asked questions
What is a smiley piercing?
A piercing through the frenulum, the thin web of tissue connecting the inside of the upper lip to the gum. It is invisible with the mouth closed and shows only when you smile widely enough to lift the lip.
Does a smiley piercing hurt?
Very little, about 2 out of 10. The frenulum is thin tissue with few nerve endings, so the pinch is brief and mild. Most people describe it as one of the easiest piercings they have had.
Why do smiley piercings reject so often?
The frenulum is thin and moves constantly with every lip and mouth movement, which gives the jewelry little to anchor into. Small, low-profile jewelry and gentle handling improve the odds, but rejection is more common here than on most other piercings.
Can everyone get a smiley piercing?
No. It needs enough frenulum tissue to hold jewelry safely. Some people have a very short or very thin frenulum with little to work with, and a piercer should decline rather than force a placement that has no realistic chance of settling.
Does a smiley piercing damage teeth or gums?
It can. The jewelry sits close to the upper front teeth and gum line, and contact over time can chip enamel or irritate the gum. Small, flat jewelry and telling your dentist about it both help.
What is a frowny piercing?
The equivalent piercing through the lower lip frenulum, connecting the inside of the bottom lip to the gum. It behaves the same way as a smiley: quick to place, quick to heal, and prone to rejection for the same anatomical reasons.
