Depending on the size of the gap and where it is in your mouth, you could use orthodontic treatment, composite resin or porcelain veneers to fix gap in teeth (diastema). Let’s take a closer look at how each of these dental treatments could help you to reduce the gap between your teeth.


What Causes Gap In Teeth?

  • Hereditary factors and genetics
  • Thumb sucking and other lifestyle habits
  • Periodontal (gum) disease
  • Disproportionately large jaw

Sometimes it is possible for gaps to be caused by tooth loss. When we lose a tooth, the other teeth in the mouth drift out of position, in order to fill the spaces left behind. 


Using Orthodontic Braces To Fix Gap In Teeth

If you have big gaps between your teeth, which may be accompanied by issues with alignment, orthodontic braces may be a good option to fix a gap between the teeth permanently. Orthodontic braces are ideal for treating a gappy smile and straightening misaligned teeth and jaws. Braces work well when you are happy with the size, shape and colour of your teeth and want to address alignment over aesthetics.

Braces or aligners are fitted over the teeth, and gently push them into the correct position. Individual treatment times vary based on individual treatment plans and range from 6 to 18 months, depending on the orthodontic treatment plan.

Using Veneers To Fix Gaps In Teeth

If most of your teeth are straight and you just want to even out small front teeth, or to close the gap between them, porcelain or composite resin veneers could work for you. Veneers work well to close small gaps and can be applied relatively quickly when compared to braces. Minimal tooth preparation is required to ready the teeth for veneers.

Composite resin veneers are more cost effective than porcelain veneers however porcelain looks more realistic in terms of the way that it reflects light, and can last for much longer than composite resin. 


Using Direct Bonding To Fix Gaps

Sometimes it is also possible to extend the surface area of the teeth to fix gaps quickly and effectively. This works when the front teeth are just a little small, making the gap seem more pronounced. Direct bonding can often be completed in just one sitting.

How do you know whether you need direct bonding, veneers or orthodontic treatment to fix gaps? If you have irregular gaps between a number of your teeth, accompanied by alignment issues of your teeth or jaws it’s likely that orthodontic treatment will suit you best. 

If however, you want to change the cosmetic appearance of your teeth, and want to increase the surface area of your teeth to make the gaps between them appear smaller, you may benefit from direct bonding or veneers.

Ultimately the best choice for you to fix gaps in teeth will be discussed in detail with your dentist, and is subject to a consultation.
