Open Bite

People with malocclusion may have abnormal tooth alignment, discomfort when chewing, rare speech difficulty such as a lisp, mouth breathing, or an unusual facial appearance.

Jaw and tooth size differences, inherited growth patterns, thumb sucking, tongue thrusting, prolonged bottle use, and eruption problems can create abnormal bite patterns.

The bite is reviewed as primary teeth, mixed teeth, and permanent teeth develop. Eruption, crowding, premature primary tooth loss, and adverse skeletal growth can change treatment priorities.

Tongue thrusting pushes the tongue between upper and lower teeth. Together with thumb sucking and prolonged pacifier or bottle use, it is a recognised habit-related factor in malocclusion.

The examination records how teeth meet and whether food can be bitten into. Dental, skull, or facial X-rays and diagnostic tooth models may be used to identify the bite problem.

Braces, bonded appliances, wires, springs, or clear aligners can reposition teeth. Extraction may help where overcrowding is part of the problem, while rare jaw discrepancies may need surgical reshaping.

Open-bite correction may use an appliance alone, include removal of crowded teeth, or rarely involve jaw surgery. The amount of correction determines treatment length.

Malocclusion can make cleaning harder and raise the risk of decay and gum disease. Appliances may cause mouth and gum irritation, temporary discomfort, or chewing and speaking difficulty.

Not every open bite is preventable. Controlling thumb sucking or tongue thrusting and identifying the bite early can make correction quicker and more successful.
