Sometimes the buccal space is reported to be the most commonly involved fascial space by dental abscesses, [2] although other sources report it is the submandibular space. [1] Infections originating in either maxillary or mandibular teeth can spread into the buccal space, usually maxillary molars (most commonly) and premolars or mandibular ...
The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to envelope the area. Each masticator space also contains the sections of the mandibular division of the trigeminal nerve and the internal maxillary artery. [4]
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space , and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle . [ 1 ]
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.

However, this term has been incorrectly used for both buccal and labial, being also applied to the side of a tooth that is adjacent to (or the direction toward) the inside of the cheek (instead of the more accurate term, vestibular). [1] [3] [4] Gingival The direction toward the gingiva (gums), synonymous with cervical and similar to apical.
This space may be created by pathology, such as the spread of pus in an infection, e.g. odontogenic infections. A periapical abscess may spread into the sublingual space if the apex of the tooth is above the level of attachment of mylohyoid, and the infection erodes through the lingual cortical plate of the mandible.
The following 9 degrees of active articulatory areas are known to be contrastive (sorted such that the top-most is in the front-most area of the mouth and the bottom-most is in the rear-most area of the mouth): [1]: 10-15 The lower lip ; Various parts of the front of the tongue : The tip of the tongue
