Crooked or twisted teeth are teeth that are not properly aligned and appear to be unaesthetic. This condition often causes people to be embarrassed about their smile, affecting their social confidence.
Crooked teeth are usually caused by lack of space in the jaws. In some circumstances, the jaws are simply too underdeveloped and are unable to host all the teeth, resulting in poor alignments. In other cases, gum diseases cause teeth to drift in unwanted directions, causing them to appear long, gappy or twisted. Sometimes extra teeth, such as supernumerary teeth and retained baby teeth, can also result in dental crowding.
