A very frequent question indeed, and one which you will likely be relieved by the answer! This is a very common situation and is usually at its worst between the ages of ten and twelve, depending on the child. It is so common in fact, that it has been given a name by orthodontists. It is called the “ugly duckling” phase of dental development.

Most times, the gap will resolve on its own once the permanent canine teeth come completely in ( around age eleven). This gap is caused by the canine teeth pushing on the roots of the front teeth as they make their way down into the mouth. This pressure pushes the teeth in the front apart temporarily and will start to close as the canines come further into the mouth. It can be a little embarrassing for teens until it resolves. So, reassure them that many of their other friends are likely to go through it also, and that it usually goes away on its own.

Occasionally, however, the gap remains slightly. This will depend on the skeletal and dental relationship of your child. If the canines have come in, and have been in for awhile but the gap still remains, talk to your dentist or orthodontist. There are many options for treating this if your child is unhappy with the final appearance of their smile. Some of those options may include anything from a small, tooth-colored filling placed to widen the appearance/close the gap, to brace or other appliances. Each child and situation is unique.

Spaces between baby teeth are indeed normal as well as helpful. However, occasionally a child has a much larger than normal space between the upper two front teeth. This large space is what we call a “diastema,” which really just means a large space or gap. They are usually caused by the presence of a little extra muscle tissue between the underside of the top lip. This muscle attaches the lip to the gum tissue between the top two front teeth. We all have this muscle attachment, but occasionally the attachment may be a little excessive or attach a little further down toward/in between the teeth than usual. This slightly different attachment is sometimes just enough to keep the two front teeth from coming together. If not corrected, this attachment can stay present as an adult and may or may not cause other problems.

In general however, this is not something to be overly concerned about until the child is older. Your dentist may choose to have your child evaluated by the orthodontist, as sometimes the space will not close on its own. It is fairly easy to fix, sometimes requiring reshaping and or relocating of the attachment to a better cosmetic place with or without the help of orthodontics. Typically no treatment is performed to fix it until the child has all or almost all of their permanent teeth. If you and your child decide not to fix it, there is usually no problem associated with leaving it other than having the space there permanently. Occasionally if left alone, (this is usually when the problem is on the lower front teeth) the attachment can cause a defect in the bone and gums, causing a host of other problems. So, it is always best to have your dentist evaluate the area regularly during check-ups or if you have concerns about the space.
