Do you know what are the causes for irregular alignment of permanent teeth?
Sizes of upper and lower jaws are not in normal proportions Projected upper teeth can be the cause of longer upper jaw than the lower jaw, whereas reversed bite can appear, if the upper jaw is smaller than the lower jaw. Sizes of teeth and jaw doesn’t match If teeth are too big the jaw may not have enough space for all the teeth to align, which can cause crowding of teeth. Same can happen if the jaw is too small. But if the teeth are too small, or the jaw is too big, there will be spaces left between the teeth and the smile will be unesthetic. Wrong number of teeth There are 28 permanent teeth (excluding the third molars). If the number of teeth is bigger, the jaw may not have enough space for all the teeth to align in a straight line. On the contrary, if there are too few teeth, there may be spaces left between the teeth.
2. EnvironmentEarly loss of milk teeth If a milk tooth is lost prematurely, most commonly because of caries, the adjacent milk teeth will migrate towards the space of the lost milk tooth, occupying the space. If this space becomes occupied, the erupting permanent tooth won’t erupt into good position. Bad habits Digit sucking and biting on a pen can push teeth into an abnormal position because of additional pressure applied on them. Gum disease Severe gum disease usually appears in adults and it can result in the loss of bone, where teeth grow. The teeth will then drift to abnormal positions. Loss of teeth Loss of teeth due to different oral diseases or tooth trauma can cause drifting of adjacent teeth. Tooth decay Decayed milk tooth will cause the neighbouring tooth to tip over and take up the space, and the teeth will become misaligned.
How to avoid irregular teeth position
Misaligned teeth that are caused because of genetics are unavoidable, but to prevent irregular teeth position caused by environment, you should stop bad habits (eg. digit sucking, pen biting, etc.) and receive proper dental treatment to prevent premature milk tooth loss and drifting of teeth.
Care for misaligned teeth
- Clean them. Clean teeth thoroughly, especially at areas with tight contacts.
- Visit orthodontist. Seek professional advice to see whether an orthodontic treatment is necessary.
