If a tumor of the parotid gland is suspected by you or your primary care doctor, you should be seen by an Ear, Nose, and Throat surgeon.
The amount of parotid gland to be removed is often determined at the time of surgery based on the size and location of the tumor or diseased portion of the gland.
Most superficial tumors are treated with removal of the superficial lobe of the parotid gland (i.e.: the portion of the gland situated superficial to the course of the facial nerve).

The amount of parotid gland to be removed is often determined at the time of surgery, based on the size and location of the diseased parotid tissue.
The most common tests to determine the nature of a parotid tumor include a CT scan (an x-ray test that helps to determine the size and position of the parotid tissues), and MRI scan (an imaging test that uses powerful magnets instead of x-rays).  FNA (fine needle aspiration biopsy), may also be helpful.
Most often the parotid gland can be removed without permanent damage to the nerve, however, the size and position of the diseased tissue may require that the nerve, or small branches of the nerve, be cut to assure complete removal.

 Dentistry: Blocked parotid gland
It is conceivable that pain originating in the parotid gland may be perceived as coming from the teeth, since both structures are served by the same sensory nerve (the phenomenon is called "pain referral").
However, disease or dysfunction of the parotid will not affect the teeth (at least directly), and disease of the teeth will likewise not affect the parotid gland.
The inflammation that results from a blocked parotid gland has a characteristic pattern: pain and swelling that increase at mealtime, owing to back-pressure from the ductal obstruction when salivary secretion is stimulated.
