Smiley Piercing: Complete Guide to Pain, Healing, Jewelry & Dental Risks

What Is a Smiley Piercing?

A smiley piercing — also called an upper lip frenulum piercing — goes through the thin strip of tissue (frenulum) that connects the inside of your upper lip to your upper gum. The jewelry sits hidden inside your mouth and is only visible when you smile, which is exactly how it got its name.

It's one of the most unique piercings you can get because it's essentially invisible until you want it to be seen. A flash of metal or a tiny gem peeking out when you laugh or grin creates a subtle, playful effect that no other piercing can replicate.

Smiley piercings have surged in popularity — searches have grown over 173% year over year — largely driven by social media where the "reveal" moment makes for great content.

Does a Smiley Piercing Hurt?

Most people rate smiley piercing pain at 2-3 out of 10 — making it one of the least painful piercings you can get. The frenulum is an extremely thin piece of tissue with relatively few nerve endings, so the needle passes through very quickly with minimal sensation.

Most people describe it as a brief pinch that's over before they can react. Some people say the clamp holding the frenulum in place is more uncomfortable than the actual piercing. The whole process takes just a few seconds.

There's minimal swelling afterward compared to other lip piercings, though your upper lip may feel slightly tender for the first few days.

Smiley Piercing Healing Time

A smiley piercing takes 4 to 8 weeks to heal — one of the fastest healing piercings. The inside of the mouth heals quickly because saliva contains natural antibacterial and healing properties, and the oral tissue has excellent blood flow.

Week 1: Mild tenderness and slight swelling around the frenulum. You may notice the jewelry more when eating, drinking, or talking. Some people experience a slight lisp for the first day or two.

Weeks 2-4: Tenderness fades significantly. The piercing starts to feel normal. You'll stop noticing it during daily activities.

Weeks 4-8: Full healing. The tissue around the jewelry is settled and comfortable. No tenderness, no discharge.

Smiley Piercing Aftercare

Because a smiley piercing is entirely inside the mouth, aftercare focuses on oral hygiene rather than external cleaning.

Do:

• Rinse with alcohol-free mouthwash or sterile saline solution after every meal and before bed.
• Maintain good oral hygiene — brush your teeth twice daily (carefully around the piercing area).
• Drink plenty of water throughout the day to keep the mouth clean.
• Eat slowly and carefully during the first week — avoid biting down on the jewelry.

Don't:

• Don't use alcohol-based mouthwash (Listerine, etc.) — it's too harsh and will irritate the frenulum.
• Don't play with the jewelry with your tongue or fingers. The frenulum is thin and delicate — excessive movement can cause it to tear or migrate.
• Don't smoke or vape during healing. Smoke and chemicals directly irritate oral piercings.
• Don't eat spicy, acidic, or extremely hot foods during the first week.
• No kissing or oral contact during healing.
• Don't pull your lip up or down to show people the piercing constantly during healing — every time you stretch the frenulum, you're irritating the wound.

Best Jewelry for a Smiley Piercing

Jewelry Types

Captive bead rings (CBRs) are the most common jewelry for smiley piercings. A small ring with a single bead closure sits along the frenulum, with the bead peeking out when you smile. The ring shape follows the natural curve of the tissue.

Seamless rings create a cleaner look — a continuous ring with no visible bead or closure mechanism. The smooth, unbroken circle looks minimal and elegant when it peeks out during a smile.

Circular barbells (horseshoes) can also work for smiley piercings. The two balls sit on either side of the frenulum and are visible when smiling. This style gives a slightly different look than a ring.

Not recommended: Flat-back labret studs are not typically used for smiley piercings because the frenulum is too thin and the stud style doesn't follow the natural curve of the tissue.

Jewelry Size

• Gauge: 16G (1.2mm) or 18G (1.0mm) — the frenulum is thin, so thinner gauges are common.
• Diameter: 6mm or 8mm for rings and horseshoes. The jewelry should sit snugly along the frenulum without putting pressure on the gums or teeth.

Best Material

Implant-grade titanium (ASTM F-136) is the safest choice for a smiley piercing. The jewelry sits directly against gum tissue and is constantly in contact with saliva, so the metal must be fully biocompatible. Titanium is nickel-free, lightweight, and won't react with oral tissue.

Avoid surgical steel (contains nickel), plated metals, and sterling silver. Sterling silver tarnishes in the mouth and can cause permanent black staining of the gum tissue.

Smiley Piercing and Dental Health

This is the most important consideration with smiley piercings. The jewelry sits directly against your upper gums and front teeth, which creates real dental risks over time.

Gum recession: The ring or horseshoe rests against the gum line above your upper front teeth. Constant contact between metal and gum tissue can cause the gums to recede over time, exposing tooth roots. This is the most common long-term complication of smiley piercings.

Enamel wear: Every time you talk, eat, or move your mouth, the jewelry shifts slightly against the back of your upper front teeth. Over months and years, this metal-on-enamel contact wears down the tooth surface. Playing with the jewelry accelerates this dramatically.

Frenulum damage: The upper lip frenulum is thin and delicate. If the jewelry is too heavy, too large, or if you play with it frequently, the frenulum can thin out, tear, or the piercing can migrate and eventually reject.

How to minimize dental risks:

• Use the smallest, lightest jewelry possible. A thin-gauge (18G), small-diameter (6mm) titanium ring puts the least pressure on your gums and teeth.
• Don't play with it. Don't push it against your teeth with your tongue, don't flip it around, don't fidget with it.
• See your dentist regularly. Tell them about the piercing so they can monitor your gum line and enamel.
• Be honest with yourself. If your dentist notices gum recession or enamel wear, consider removing the piercing. Dental damage is permanent.

How Long Do Smiley Piercings Last?

This is something most people don't realize before getting a smiley: smiley piercings are not usually permanent.

The upper lip frenulum is a very thin piece of tissue. Over time — months to years — the jewelry can migrate through the tissue, causing the piercing to grow out. Some people keep their smiley for years without issues. Others lose theirs within a few months.

Factors that affect how long a smiley lasts:

• Frenulum thickness: Thicker frenulums hold piercings longer. If yours is very thin or small, the piercing may not last as long.
• Jewelry weight and size: Lighter, smaller jewelry puts less strain on the tissue.
• Habits: Playing with the jewelry, pulling the lip to show people, or biting on it all accelerate migration.
• Oral hygiene: Poor oral health can weaken the tissue around the piercing.

If you notice the jewelry sitting differently than it used to, or the frenulum looks thinner where the piercing passes through, it may be migrating. See your piercer — it's better to remove it before it tears through completely.

Smiley Piercing Anatomy — Can Everyone Get One?

No — not everyone has the anatomy for a smiley piercing. Your piercer needs to check two things:

Frenulum size: You need a frenulum that's large enough and thick enough to support a piercing. Some people have a very small, thin, or almost nonexistent upper lip frenulum. If yours is too small, the piercing won't have enough tissue to hold jewelry safely.

Frenulum position: The frenulum should connect to the lip in a position where the jewelry won't rest directly against the teeth or gums in a way that causes immediate contact damage.

Your piercer will flip your upper lip up and examine the frenulum before agreeing to do the piercing. If they say your anatomy isn't right for it, trust them — forcing a smiley piercing on unsuitable anatomy leads to fast rejection and potential dental damage.

Smiley Piercing Cost

A smiley piercing typically costs $30 to $60 at a reputable studio, including basic jewelry. It's one of the simpler piercings to perform, so it tends to be on the lower end of the pricing spectrum. As always, choose your piercer based on experience and reviews, not price.

Smiley vs Frowny Piercing

A frowny piercing is the lower lip version of a smiley — it goes through the frenulum that connects the inside of the lower lip to the lower gum. It's only visible when you pull the lower lip down.

Frowny piercings are much less common than smileys because the lower frenulum is typically thinner and smaller, making it harder to pierce and more prone to rejection. The dental risks are similar — metal against gums and teeth.

Common Problems and Solutions

Migration and rejection: The most common issue with smiley piercings. The frenulum is thin, and the jewelry can slowly migrate through the tissue over time. If you notice the piercing moving or the tissue thinning, see your piercer.

Tearing: If the jewelry gets caught on something (a fork, a toothbrush, a finger pulling the lip up), the thin frenulum can tear. Be gentle around the piercing at all times.

Gum irritation: If the ring is too large or sits at the wrong angle, it can press against the gums and cause soreness or recession. Your piercer can adjust the jewelry size if this happens.

Plaque buildup: Jewelry inside the mouth collects plaque and bacteria faster than external piercings. Clean the jewelry regularly and maintain good oral hygiene to prevent buildup.

Irritation bumps: Less common with smiley piercings than external piercings, but they can occur on the frenulum if the jewelry is causing friction. Saline rinses and leaving the jewelry alone usually resolves them.

Smiley Piercing FAQs

Can you see a smiley piercing when your mouth is closed?
Usually no. That's the whole appeal — the jewelry is hidden inside your mouth when your lips are together and only peeks out when you smile or laugh. With a very large ring or if your upper lip is thin, a small amount of metal might be visible at rest, but for most people it's completely hidden.

How long until I can change my smiley jewelry?
Wait at least 4-8 weeks until fully healed. Have your piercer do the first change to make sure the tissue is strong enough and the new jewelry fits properly.

Can I brush my teeth normally with a smiley piercing?
Yes, but be careful around the frenulum area. Use a soft-bristle toothbrush and brush gently near the piercing. Don't catch the jewelry with the toothbrush bristles.

Will a smiley piercing affect my speech?
Minimally. Some people notice a very slight difference for the first day or two, but because the jewelry is small and sits along the gum line, most people adjust almost immediately.

Can I eat normally with a smiley piercing?
Yes, after the first few days. You'll learn to eat without biting the jewelry quickly. Be careful with crunchy foods and utensils — forks and spoons can catch on the ring if you're not paying attention.

Is a smiley piercing permanent?
Not always. Many smiley piercings eventually migrate or reject because the frenulum is thin. Some last years, others last months. Think of it as a semi-permanent piercing and enjoy it while it lasts.
