Hi and thanks for the query.
This might be a dental sinus infection. This needs to be examined as soon as possible. Pain from dental sinus infections can often be referred to the ear and vice versa. This can also be an infection or blockage of the parotid gland duct which opens near the upper 1st molar on the cheek. Debris and small stones can block the duct and cause inflammation and infection, these are refractory to antibiotics most of the times, if salivation or the sight of food increases the pain, then the later is likely. I would suggest that you visit your PCP and have your ears and oral cavity examined as well. Meanwhile, I would suggest saline gargles thrice a day and Advil 400 mg thrice a day for pain relief.
Let me know if you have more queries.
