Teeth gaps, medically known as diastemas, are spaces between two teeth that can occur anywhere in the mouth but are most noticeable between the upper front teeth. While some people embrace these gaps as a unique aspect of their smile, others may seek treatment for aesthetic or functional reasons. This article covers the main treatment options at Dazzle Dental Clinic for closing or managing teeth gaps.
What Causes Teeth Gaps?
Teeth gaps can result from a variety of factors including a discrepancy between jaw size and tooth size; a large labial frenum (the tissue connecting the upper lip to the gum); early loss of primary teeth that causes adjacent teeth to drift; missing teeth creating spaces in the arch; or habits like thumb-sucking or tongue-thrusting that push teeth apart over time.
Orthodontic Treatment
For gaps caused by tooth position or jaw/tooth size discrepancy, clear aligners or braces are the most appropriate first-line treatment. Orthodontics moves teeth to their correct positions, closing the gap through actual tooth movement rather than masking it with restorations. Clear aligners are particularly popular with adult patients seeking gap closure without visible metal brackets. Retainers are worn after treatment to maintain the corrected positions. See our composite resin guide for how bonding compares.
Composite Bonding
For small to moderate gaps, composite bonding is an immediate single-appointment solution. Tooth-coloured composite resin is applied to the adjacent teeth to widen them and close the gap. No anaesthesia, no tooth reduction in most cases, and the result is visible in a single visit. Composite bonding is appropriate for: gaps of 1–3mm where the tooth proportions will still look natural after widening; patients who want an immediate result; cases where orthodontics is not desired or indicated.
Dental Veneers
For larger gaps or cases where colour, shape, and proportion correction are needed alongside gap closure, porcelain veneers address multiple aesthetic concerns simultaneously. Veneers require minimal tooth preparation and deliver a longer-lasting result than composite bonding. A digital smile design ensures the tooth proportions after gap closure still look natural. See our smile makeover veneer guide for more detail.
Implants or Bridges for Missing Tooth Gaps
When a gap is caused by a missing tooth (not just drifting of present teeth), an implant or bridge is the appropriate treatment rather than orthodontics or bonding. A gap from a missing tooth that is closed orthodontically without replacing the root creates long-term bone resorption at that site.
Which Treatment Is Right?
The right treatment depends on the cause of the gap, the size of the gap, the overall dental health, and the patient's aesthetic goals. At Dazzle Dental Clinic, a consultation and clinical examination determines the cause before recommending treatment. Our experienced team of cosmetic and orthodontic specialists is dedicated to helping you achieve a healthy, beautiful smile, utilising the latest in dental technology and materials, ensuring that your treatment is as effective and comfortable as possible.
