The width of the gums and jawbone is called the dental arch
Crowded teeth occur when there isn’t enough space in the dental archEach tooth
It develops when the teeth cannot be aligned properly.
Crooked teeth can make it harder to maintain good oral hygiene, and periodontal disease and tooth decay can develop more easily. Your upper and lower teeth may also fit together poorly, reducing your chewing ability.
Most types of crowded, protruding teeth require tooth extraction for orthodontic treatment. The space created by extraction allows each tooth to move into a suitable position and angle for a straight alignment.
