In extreme cases, this can affect the talking with problems in pronouncing some letter. The molars that do contact have an excess of work, so they get spioled before and sometimes there’s pain in the articulation of the jaw.
The chin and the teeth deviate towards a side. Unconsciously, the patient tend to bend the head to reduce the defect, so that’s why sometimes they suffer pain in the neck. There can also be some problems in the articulation.
