You may not think about how important your molar teeth are until they begin causing problems. And posterior crossbites tend to cause painful problems over time. But why does this happen? Because the human body often has to deal with imperfections like crossbites, it finds ways to adjust.
If you have a posterior crossbite, your jaw may naturally try to shift into a more comfortable position. When this happens, not only do the teeth begin rubbing and grinding on each other, but it also affects your jaw muscles.
Another side effect is a condition called temporomandibular joint (TMJ) dysfunction or TMD for short. TMD causes symptoms like neck pain, jaw pain, headaches, and chewing problems. This condition is more common in adults and has other related causes, but untreated crossbites are a risk factor for developing TMD.
This response, however, causes problems where the teeth come in contact. For instance, misaligned teeth will wear down faster at the point of contact, and make it easier for your child to get cavities.
