What is malocclusion? Malocclusion isn’t actually a common term but has a lot to do with a misaligned jawbone. The position of the bites is important when it comes to dental care and appropriate use of the teeth. There can be cases where the teeth aren’t aligned properly which results in bad bite and mismatch of the teeth. Unlike the normal situation where the upper and the lower teeth fit slightly and perfectly on each other, the case is different for those suffering from malocclusion.
