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!
Your tooth are innervated by trigeminal nerves (CN V). There are three divisions of trigeminal nerve. The upper teeth are innervated by the maxillary (V2) division and lower teeth are innervated by mandibular (V3) division.

The nose
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 second cranial nerve is the optic nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
Cranial nerve 4 (IV) is the trochlear nerve.
