Hello & welcome,
The gap between Upper Incisors is called as Mid-line diastema
in dental language & is mostly seen in those individuals who have Thick Labial frenum.
This may occur even with labial frenum with higher attachment between the upper two central incisors. Due to higher attachment, when patient smiles or talks, the labial frenum is stretched which in turn moves the central incisors apart from each other in opposite direction.
Another reason for mid-line diastema is having a tongue thrusting habit. Here patient moves the tongue forward against the upper central incisor teeth while swallowing or even talking thereby causing bi-maxillary protrusion. Teeth goes on protruding creating the gap between them due to the pressure applied by the tongue.
Periodontal or gingival infection specially in severe condition leads to bone resorption
thereby creating the gap between the teeth.
If oral hygiene
is not maintained properly by the patient, then food & plaque
accumulation is associated with gum & periodontal diseases. There is calculus formation on the teeth surface which may harbor the infection involving the periodontal fibers causing the teeth to move apart.
habit in childhood is also responsible for mid-line diaestema.
Visit your Orthodontist as soon as possible. He will clinically examine the condition to exactly determine the cause of the gap & treatment will be depending upon the finding.
You may have to undergo frenectomy
if frenum attachment is thicker or higher in which only braces won't work alone.
