Gap between teeth (diastema)

Routine — book when convenient

The short answer

A gap between front teeth (diastema) is cosmetic in most cases but can also be caused by a low lip-tie (labial frenum), missing teeth, or bite misalignment. Fixable three ways: composite bonding (OMR 55-95/tooth, same visit, reversible), Invisalign (OMR 1,500-2,500, 4-9 months), or porcelain veneers (OMR 180-280/tooth, permanent).

What's happening

The clinical picture

The most common gap is between the two upper front incisors — genetic in most cases, often cultural (considered beautiful in parts of West Africa, ordinary in Oman). Clinical causes to rule out: a thick labial frenum (the band of tissue between upper lip and gum) pulling the teeth apart, undersized upper lateral incisors (which leaves excess room the big centrals don't fill), or periodontal bone loss letting the teeth drift apart. The treatment choice depends on the cause: a frenectomy is needed before orthodontic closure if the frenum is the culprit; otherwise it's an aesthetic decision between the three fixes above.

Warning signs

Contact us the same day if:

  • New gap appearing in adulthood (not childhood — suggests bone loss)
  • Gap widening over months
  • Teeth feeling loose around the gap
  • Food trapping in the gap constantly
  • Gap accompanied by receding gums

What we do

Our approach

Exam + intraoral photos + X-ray to rule out bone loss. Digital smile design to preview each option — you see exactly how it'll look before committing. For young adults with a simple gap, composite bonding done same day is often the best starting point. For mild crowding elsewhere plus the gap, Invisalign addresses both. For complex smile makeovers involving multiple teeth, porcelain veneers.
