Trigeminal (V) cranial nerve
Not all toothaches are due to infection.
You can have pain due to the possibility of a cavity, gum disease, or even your wisdom teeth (the human mouth usually does not have room for wisdom teeth causing the to push against the teeth in front of them.
Do not wait to long going to the dentist as it can get worse and can get very expensive.
Hope this helps!

Trigeminal neuralgia is a rare disorder of the sensory fibers of the trigeminal nerve (fifth cranial nerve), which innervate the face and jaw. The neuralgia is accompanied by severe, stabbing pains in the jaw or face.
Trigeminal (5th) cranial nerve
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The optic nerve (cranial nerve II) is not involved in taste, as its primary function is vision. Taste is primarily mediated by the facial nerve (cranial nerve VII), glossopharyngeal nerve (cranial nerve IX), and vagus nerve (cranial nerve X).
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
Cranial Nerve 2 - Optic Nerve
Nerve X, Vagus
The second cranial nerve is the optic nerve.
The vestibulocochlear cranial nerve controls hearing.
