What are the consequences of dental crowding in terms of general health? How is the treatment done? Tooth crowding can cause tooth decay and gingival problems, can negatively affect basic behaviors such as nutrition and speech, and therefore should be treated without delay. Such dental problems can also cause bacteria to enter the bloodstream and, in rare cases, some systemic problems. Closure disorders can cause jaw joint problems, headache, teeth grinding, muscle pain and nutritional disorders. In addition, closing disorders can undermine self-confidence and harm social relationships by causing the person to not laugh freely, both in young people and adults. For a long time, braces were the only option in the treatment of crooked teeth.
