What are protruding teeth?
In orthodontics, the distance by which the upper front teeth sit in front of the lower front teeth is called overjet. When this distance is increased or the upper front teeth tilt too far forward, people commonly call them “buck teeth” or protruding teeth. Common complaints are lips that cannot fully cover the teeth, difficulty closing the lips and teeth that look prominent when smiling.
Causes
- Dental causes: Forward-tilted front teeth, gaps between the teeth
- Skeletal causes: A retruded lower jaw or a protruding upper jaw
- Habits: Long-term thumb sucking, tongue thrust, tucking the lower lip behind the upper teeth
- Mouth breathing
- Heredity
Why does it matter?
Protruding upper front teeth break more easily in falls and knocks. Early assessment is recommended especially for children, who face a higher risk of injury during play and sport. In addition, lips that do not cover the teeth can contribute to a dry mouth and gum inflammation.
Treatment options
Clear aligners
Where protrusion is dental, especially if there are gaps between the front teeth or space can be gained, the front teeth can be moved back with clear aligners.
Braces
In cases with marked overjet that need extensive bite correction, fixed treatment may be preferred. Elastics or mini-screws can be used if needed.
Functional appliances during growth
If the protrusion is caused by a retruded lower jaw, appliances that bring the lower jaw forward or mandibular advancement with clear aligners can be considered during growth.
Extraction and surgery
In advanced cases, extraction may be considered to gain space, and in adults who have finished growing and have a marked skeletal problem, orthognathic surgery may be discussed.
