Forwardly Placed / Protruding Teeth
Dental Protrusion — Causes, Risks & Modern Orthodontic Correction
- Yelahanka, Bangalore | GardenCity Smiles
Protruding or forwardly placed teeth — commonly called buck teeth — is one of the most common orthodontic problems in India. Upper front teeth that jut out affect appearance, speech, function, and tooth safety. Modern orthodontics can correct this at any age.
- Protruding front teeth are at higher risk of fracture from trauma — especially in children during sports.
- Key Signs to Watch For
- Upper front teeth visibly jutting forward when viewed from the side
- Difficulty fully closing the lips over the front teeth
- Upper lip appearing pushed forward; lower lip curling under the upper teeth
- A gap between upper and lower front teeth even when biting together
- Mouth breathing — lips cannot close comfortably
- Visible gaLisping or difficulty pronouncing certain sounds — S, Z, THp between teeth where food enters
Patient Education
Understanding This Condition
Dental protrusion refers to upper front teeth that are positioned too far forward relative to the lower teeth or the face. It is classified by the overjet — the horizontal distance between upper and lower front teeth.
Normal overjet: 2–4 mm. Mild protrusion: 5–7 mm. Moderate: 7–10 mm. Severe: more than 10 mm.
Two types of protrusion:
Dental protrusion — the teeth are tilted forward but the jaws are in a normal position. Correctable with orthodontics alone.
Skeletal protrusion — the upper jaw is genuinely too far forward relative to the lower jaw. In growing children this can be corrected with jaw orthopaedics. In adults, severe skeletal cases may require orthognathic surgery combined with orthodontics.
Why it matters beyond aesthetics: Protruding upper front teeth are the most commonly chipped or fractured in falls and accidents. Studies show children with overjet greater than 6 mm are twice as likely to sustain dental injuries.
Signs & Symptoms
How to Recognise This Condition
Even mild symptoms warrant professional evaluation — early treatment is always simpler and less costly.
- Upper front teeth visibly jutting forward when viewed from the side
- Difficulty fully closing the lips over the front teeth
- Upper lip appearing pushed forward; lower lip curling under the upper teeth
- A gap between upper and lower front teeth even when biting together
- Mouth breathing — lips cannot close comfortably
- Lisping or difficulty pronouncing certain sounds — S, Z, TH
- Front teeth feel prominent when smiling
- Pus between teeth and gums when you press the gum
- Tooth sensitivity due to root exposure from recession
Root Causes
Why This Happens
Understanding the cause is the first step to choosing the right treatment and preventing recurrence.
- Genetics — jaw and tooth size and position are largely inherited
- Thumb or finger sucking beyond age 4–5 — forces upper teeth forward and narrows the upper jaw
- Prolonged pacifier use beyond 3 years
- Tongue thrusting — an abnormal swallowing pattern where the tongue pushes against the front teeth
- Mouth breathing from allergies, enlarged adenoids, or deviated septum
- Early loss of baby teeth causing eruption path changes
- Dental crowding pushing front teeth forward
- Skeletal jaw discrepancy — maxillary prognathism or mandibular retrognathia
Treatment Options
How We Treat This at GardenCity Smiles
All treatments are explained fully during your consultation. We always recommend the most conservative effective option first.
Invisalign Clear Aligners
For moderate dental protrusion in adults and teens, Invisalign can retract the upper front teeth significantly using precision attachments and sequential aligner movements. No metal, virtually invisible, removable for eating and cleaning. We are a certified Invisalign provider at GardenCity Smiles.
Fixed Orthodontic Braces
Metal or ceramic (tooth-coloured) braces provide reliable, precise tooth movement including retraction of protruding teeth. Typically used when protrusion is moderate to severe. Treatment duration: 18–24 months on average.
Functional Appliances (Growing Children)
In children aged 8–12 who are still growing, functional appliances (Twin Block, Herbst appliance) harness jaw growth to encourage the lower jaw to grow forward — correcting a skeletal underpinning without surgery. This is the ideal time to intercept skeletal protrusion.
Premolar Extraction + Orthodontics
In cases of severe protrusion or crowding, removing two upper premolars creates space for the front teeth to be retracted significantly. The space closes as part of orthodontic treatment, not left as a gap. This is a well-established, safe approach.
Orthognathic Surgery + Orthodontics (Severe Skeletal Cases)
For adults with true skeletal protrusion or significant jaw discrepancy, a combination of orthodontic alignment and surgical jaw repositioning provides permanent correction.
Habit Breaking Appliances
For children with thumb-sucking or tongue-thrusting habits causing protrusion, a habit-breaking appliance stops the habit — after which teeth often self-correct with normal jaw growth.
In-Depth
What Every Patient Should Know
Protrusion is almost always best treated during childhood or adolescence while the jaws are still growing — this is when the most correction is possible with the least complex treatment. However, adults also achieve excellent results with Invisalign or braces, though skeletal discrepancies in adults require surgery to fully correct.
The tongue thrusting connection: Many people with protrusion have a tongue thrust — an abnormal swallowing pattern where the tongue pushes forward against the teeth on every swallow — approximately 2,000 swallows per day. Without correcting the tongue thrust through myofunctional therapy, orthodontic correction is prone to relapse.
Retainer wear: After any orthodontic correction of protrusion, a fixed retainer behind the front teeth and a removable retainer at night are essential for life. Without retention, teeth naturally drift back toward their original position.
Prevention
How to Prevent This
Prevention is always better — and far less costly — than treatment. These evidence-based habits can significantly reduce your risk.
- Wean children from pacifiers by age 2–3 and thumb-sucking by age 4–5
- Have children's mouth-breathing investigated by an ENT — enlarged adenoids and tonsils are common causes
- Begin orthodontic evaluation at age 7 — early intervention is more effective than adult correction
- Address tongue-thrusting early with myofunctional therapy
- Protect protruding teeth during sports with a custom mouthguard
When to See a Dentist
Do not wait if you experience any of these — early intervention always leads to better outcomes and lower treatment cost.
- You or your child has prominent upper front teeth the lips cannot comfortably cover
- Your child is over 5 and still thumb-sucking or using a pacifier
- A child is 7–8 years old — the ideal time for an orthodontic evaluation
- Front teeth were injured — they are more vulnerable when protruding
- Difficulty biting into food due to the teeth position
- You are diabetic and have not had a dental check in 6 months

Frequently Asked Questions
Answers from Dr. Deepthi Kalahasti and the GardenCity Smiles team.
For moderate dental protrusion, Invisalign with precision attachments can achieve excellent retraction of upper front teeth. Severe protrusion — especially skeletal — is better managed with braces or combined with surgery. We assess each case individually.
No — when premolar extraction is part of an orthodontic plan, the braces use the extraction space to retract the front teeth. The spaces close completely as treatment progresses. There are no visible gaps in the final result.
Unfortunately, dental protrusion does not self-correct during growth. If anything, it may worsen as permanent teeth come through. Skeletal protrusion can improve with jaw growth but is better managed proactively with a functional appliance.
