People may need braces if they lose their baby teeth later than normal, if they experience abnormal jaw clicking or if their bite does not close in a matched pattern, according to Delta Dental. Chewing problems or biting the cheeks are additional indicators that braces may be necessary.
People with crooked teeth or teeth that are pushed out of a row commonly require braces to realign the teeth, notes Delta Dental. The majority of teeth and jaw complications are inherited genetically from a parents, but detrimental habits such as thumb-sucking can also cause the need for braces. Some people suffer from extreme malnutrition or experience injuries that require braces to fix their dental problems.
Disproportionate jaw shapes or bite complications such as overbites or underbites are often treated successfully with braces. WebMD stresses the importance of braces in preserving the health of patients' teeth, especially if adults are suffering with chronic misalignments. If these conditions go untreated, they can lead to poor overall dental health through plaque build-up, periodontal disease and gum disease. Continued jaw imbalances can cause painful headaches and muscle tension.
As of 2014, orthodontists have several options available to correct dental issues, such as metal braces, clear braces and removable aligners. Adults pay an average of $4,800 for a set of braces, according to WebMD.
