Dental Pain from Surrounding Structures
Non-odontogenic pain is pain that is not associated with the teeth but involves other orofacial tissues. Non-odontogenic pain can be difficult to diagnose and can vary in severity. The following conditions can mimic pain from a toothache and may be the reason a patient presents to a dental clinic with pain.
Pain from Maxillary Sinus
Pain can originate from the maxillary sinus because there is only a thin plate of bone separating the maxillary teeth from the sinus; inflammation from the sinus lining from infections can lead to facial pain that can be felt in the teeth.This type of pain is a dull aching pain and may be exacerbated by bending over or lying down.
Pain from TMJ
Temporomandibular joint dysfunction syndrome (TMD) is a term used to describe a number of disorders affecting the temporomandibular joints, masticatory muscles and other structures associated with this region. Common complaints from patients include pain in the muscles around the mouth, pain in the temporomandibular joint upon use, headache, earache, locking or clicking of the jaw and tinnitus.
Pain from Neurovascular Structures
Non-odontogenic pain can also be of neuromuscular origin; examples include muscle tension headache, neck pain, whiplash and fibromyalgia. Pain can be evident in the facial muscles and the neck may be tender, dysfunction of muscles may also be evident. Neurovascular pain refers to a group of disorders involving the trigeminal neurovascular system.
This condition is most often associated with headaches but can also involve infection or tumors; the pain occurs with the headache and usually subsides when headache ceases. This type of pain may need a referral to a physician as in some cases can be life-threateningNeuropathic pain can mimic toothache when it involves the nerve supply to the teeth.
This can be caused by trauma, inflammation or tumors in the oro-facial region. Trigeminal neuralgia is the most well known in the dentistry field. Toothache type pain may also be felt in the presence of oral cancer, squamous cell carcinoma occurring in the oral mucosa may present with pain and sensory problems.
