Abstract:
The terms 'persistent idiopathic facial pain' (PIFP) and 'atypical odontalgia' (AO) are currently used as exclusion diagnoses for chronic toothache and chronic facial pain. Knowledge about these pain conditions in medical and dental practices is of crucial importance for the prevention of iatrogenic tissue damage by not-indicated invasive interventions, such as endodontic treatment and tooth extraction. In the present paper, etiology and pathogenesis, differential diagnostic criteria, and diagnostic approaches will be explained and relevant therapeutic principles will be outlined.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
