Crowding is the lack of space for all the teeth to fit normally within the jaws. Crowding occurs when there is disharmony in the tooth to jaw size relationship or when the teeth are larger than the available space. The teeth may be twisted or displaced. Crowding can be caused by improper eruption of teeth and early or late loss of primary teeth. If the crowding is too severe then it may be indicated to have premolars extracted.
Lower incisor crowding often occurs in the mid thirties and gets worse over time. This problem may lead to adults seeking braces even if they have had braces as children. If the crowding is severe a tooth may need to be extracted or the lower teeth may need to be made thinner by reproximation. Reproximation can also be carried out for treatment of tooth size discrepancies.
Crowding should be corrected because it can:
- prevent proper cleaning of all the surfaces of your teeth
- cause dental decay
- increase the chances of gum disease because the bone and gums over the roots of extremely crowded teeth may become thin and recede as a result of severe crowding.
- cause Impacted teeth (teeth that should have come in, but have not),
- lead to a poor biting relationships which prevent proper functioning of teeth
- make your smile less attractive due to the undesirable appearance of crowded teeth.
