Large gaps in your teeth can be fixed, but you need to be specific about the problem. There are parts that can be fixed and parts that are difficult to fix. For example, the most common case of a large gap is the gap between the center of the upper jaw, which is what we call the gap between the two incisors. If this kind of gap is not particularly large, you can apply a restorative method to repair it, by restoring 1 layer of resin in the proximity of each of the 2 incisors, and then it looks like there is no obvious gap between the teeth. However, this restoration method has a high requirement of indications, first of all, the gap should not be too wide, too wide a gap due to the restoration will look obviously unattractive, and it is easy for the restoration to fall off when biting. The second thing to check is whether there is the presence of supernumerary teeth in the upper jaw, there is a wide gap in the upper jaw caused by the child’s supernumerary teeth. This should be done by first extracting the supernumerary teeth and then repairing the gap. But if this is not the case, and it is the back teeth that have wide gaps, or the front teeth that have too wide gaps, we usually need to apply orthodontic treatment.
