Oral anatomy is more variable than people realise
Tongue piercings and other oral piercings depend on features of the mouth that vary significantly between individuals: tongue thickness, frenulum length and position, teeth alignment, and how the tongue sits in the mouth at rest. Some people have textbook anatomy for tongue piercings. Some have anatomy that makes standard tongue piercings difficult or unsafe. And a small percentage have anatomy that essentially rules out tongue piercings entirely.
This guide covers the oral anatomy relevant to tongue and other mouth piercings, how to self-assess before consulting a piercer, and what alternatives exist when standard placements are not feasible. Oral piercings deserve particular attention because complications can affect long-term dental and oral health.
Tongue anatomy
Tongue thickness
• Tongue thickness varies substantially between individuals
• A thicker tongue supports standard barbell length comfortably
• A very thin tongue may require shorter barbells and different placement
• A very thick tongue may require longer barbells that some studios do not stock
• A piercer measures your tongue thickness before choosing jewellery
Tongue frenulum (lingual frenulum)
• The tongue frenulum is the tissue strip connecting the underside of your tongue to the floor of your mouth
• Standard tongue piercings sit above the frenulum, in the centre of the tongue
• A short or high frenulum limits how far forward the piercing can be placed
• A very short frenulum (ankyloglossia, tongue-tie) may prevent tongue piercing entirely if the tongue cannot lift enough for the piercer to work
Blood vessels and nerves
• The underside of the tongue has visible blood vessels that piercers must avoid
• The vessels are visible under the tongue when lifted, avoiding them is a matter of proper placement
• A skilled piercer identifies the vessels and places the piercing precisely to avoid them
• Nerve anatomy is also considered, though nerves are less visibly obvious
Teeth and gum considerations
Teeth positioning
• Tongue piercings sit inside the mouth and can contact teeth during speech, eating, and rest
• Constant contact between metal and teeth causes enamel wear over years
• The specific teeth affected depend on tongue piercing placement and tongue movement
• Front teeth (incisors) are most commonly affected, though molars can also show wear from long-term wearers
Jewellery choice reduces risk
• Metal balls at both ends of tongue barbells increase tooth contact risk
• Silicone or bioplast balls (softer materials) reduce dental damage significantly
• Smaller ball sizes reduce contact area
• Shorter barbells (once the initial swelling reduces) reduce movement inside the mouth
Gum recession
• Tongue piercings that press against gum tissue during eating or speech can cause gum recession over years
• Placement affects this significantly, well-placed piercings reduce gum contact
• Regular dental checkups are important for monitoring gum health
Self-assessment for tongue piercings
1. Open your mouth and look at your tongue in the mirror.
2. Stick your tongue out and observe its shape and thickness. Is it comparatively thick or thin?
3. Lift the tip of your tongue up toward the roof of your mouth. Can it reach easily?
4. Look at the underside of your tongue in the mirror. Can you see the frenulum (the tissue strip connecting your tongue to the floor of your mouth)?
5. Assess the frenulum, is it a defined strip that allows your tongue to lift and move freely, or is it short and restrictive?
6. If your tongue lifts poorly or you have limited tongue mobility, this may signal tongue-tie or a short frenulum that could complicate piercing.
7. Look at your front teeth from the inside using a small hand mirror. Are they positioned in a way that would constantly contact a tongue piercing?
This self-assessment does not replace a professional oral examination but helps you arrive at the consultation informed.
Other oral piercings and their anatomy
Tongue web piercing
Passes through the frenulum on the underside of the tongue. Requires a well-developed frenulum, absent or very short frenulums make this impossible. Even suitable tongue web piercings have limited lifespans due to constant tongue movement.
Snake eyes and venom bites
These horizontal tongue piercings involve placing barbells across the tongue rather than through it vertically. They are controversial in piercing communities because they can cause significant dental damage and speech impact. Reputable piercers often refuse to do them regardless of anatomy. If you are considering these, understand the risks and seek studios with genuine expertise, not just willingness to pierce.
Frowny piercing
The counterpart to smiley, passing through the lower lip frenulum. Requires a suitable lower frenulum, which varies enormously between individuals. Even suitable frowny piercings have short lifespans.
What piercers assess for oral piercings
The oral consultation
A proper oral piercing consultation involves the piercer examining your mouth open, looking at tongue size and mobility, checking the frenulum, assessing teeth positioning and general dental health, and discussing your dental history. They will measure your tongue for jewellery sizing. They will show you the intended placement and explain how it should sit relative to your teeth. If a piercer books tongue piercings without any oral examination, or dismisses questions about dental risk, choose a different studio. Oral piercings have real long-term dental consequences and deserve careful consideration.
When to postpone or reconsider
• Recent dental work (braces recently removed, ongoing orthodontic treatment, recent implants or veneers)
• Active dental disease (untreated cavities, gum disease)
• Very thin tongue with poor mobility
• Very short or restrictive tongue frenulum
• Teeth positioning that would guarantee constant contact
• Any oral infection or sore currently active

Frequently Asked Questions
How do I know if I can get a tongue piercing?
Check three main things. First, tongue thickness and mobility (can you stick your tongue out, lift it toward the roof of your mouth easily?). Second, your frenulum (the tissue strip under your tongue), is it a defined strip allowing free movement, or short and restrictive? Third, your teeth positioning, are your front teeth aligned in a way that would constantly contact a tongue piercing? Most people have suitable anatomy for standard tongue piercings, but a proper oral examination by a piercer confirms specific suitability.
Will a tongue piercing damage my teeth?
Potentially yes, over years of wear. Tongue piercings contact teeth during speech, eating, and rest, which can cause enamel wear over time. The risk depends on placement, jewellery choice (metal versus softer materials), and how you position your tongue at rest. Wearing softer material end balls (silicone, bioplast) reduces damage significantly. Regular dental checkups are essential for tongue piercing wearers. Some anatomy makes dental damage essentially unavoidable, in which case reconsider the piercing.
What is tongue-tie and how does it affect piercings?
Tongue-tie (ankyloglossia) is when the tongue frenulum is short or restrictive, limiting tongue mobility. Mild tongue-tie may not affect standard tongue piercings but can limit placement options. Significant tongue-tie can prevent tongue piercings entirely if the tongue cannot lift enough for the piercer to work safely, or if the frenulum position makes standard placement impossible. A piercer will assess frenulum during oral examination. If you have known tongue-tie, discuss with your piercer before booking.
Are snake eyes piercings safe?
Not particularly. Snake eyes piercings (horizontal barbells across the tongue) can cause significant dental damage and can impair speech and tongue movement. They are controversial in professional piercing communities, and many reputable piercers refuse to do them regardless of client anatomy. If you are considering snake eyes, understand the risks carefully. Seek studios with genuine expertise and willingness to discuss risks honestly, not studios simply willing to pierce. Regular dental monitoring is essential for anyone who has snake eyes piercings.
What jewellery is best for tongue piercings to protect my teeth?
Implant-grade titanium barbells with silicone or bioplast end balls reduce dental damage compared to standard metal balls. Smaller ball sizes reduce contact area. Shorter barbell lengths (once initial swelling reduces) reduce piercing movement inside the mouth. Discuss with your piercer about downsize appointments to move to shorter barbells once swelling completes. Regular jewellery inspection helps identify wear that could increase tooth contact risk.
Do I need to see my dentist before getting a tongue piercing?
Discussing with your dentist is worthwhile if you have ongoing dental concerns, active dental treatment (braces, planned implants, veneers), history of gum recession, or any dental health complications. Your dentist may identify specific risks based on your teeth positioning and gum health. If you have no significant dental concerns, direct consultation with a reputable piercer is usually sufficient. However, any recent dental work should be complete before tongue piercing.
How long can I keep a tongue piercing?
Well-placed tongue piercings can be kept for many years or indefinitely. However, monitoring is essential, dental wear develops slowly and can be significant by the time it is visible. Regular dental checkups (every 6 to 12 months) monitor for enamel wear and gum recession. If dental damage is developing, consider whether to keep the piercing or retire it. Many long-term tongue piercing wearers do retire the piercing in their 30s or 40s to prevent further dental damage.
