I have spaces in my teeth, which I would like closed. I was told that the spaces can be ‘filled’. Is this a good option or should I have this corrected orthodontically?

Dear G.N.,
Gaps can be closed through various methods. The key is assessing the cause and nature of the spacing, the location, the size of the space and the size of neighbouring teeth.

With composite resin bonding, a tooth-coloured filling material is added to the teeth to make them bigger so as to close the spaces. Composite resin bonding only works when the spaces are small and quite symmetrical on both sides. Porcelain veneers may also be a solution if a more permanent solution is desired.

There are various ways to close gaps with orthodontic treatment – fixed braces (metal or tooth-coloured ceramic braces), removable appliances, or Invisalign (series of removable clear aligners). Braces are a more versatile method to address gaps between teeth as braces can close spaces of various sizes and positions, and re-distribute the remaining spaces for an aesthetic filling. Braces can also be combined with composite resin bonding.
Occasionally, spacing between teeth is a reflection of underlying gum disease, so this should be ruled out prior to further treatment.

There are multiple variables in treating spacing conditions so an accurate diagnosis is the most important part. Ideally, one should have a joint consultation with a prosthodontist, periodontist and an orthodontist so that a comprehensive treatment plan can be prescribed.
