What You'll Learn
The buccinator muscle is the main muscle of the cheek
The buccinator muscle is also responsible for several facial expressions, as it compresses the cheeks. This can be the precursor to whistling, blowing a kiss, sucking on a lemon, or an infant suckling at its mother's breast. The muscle is also used to expel air from the mouth, which is important for playing wind instruments and blowing.
The buccinator muscle is a square, bilateral muscle situated in the mobile and adaptable cheek area. It is composed of three muscular bundles, two of which have a bony origin. The maxillary bundle arises from the buccal portion of the maxilla's alveolar process, while the mandibular bundle originates from the buccal portion of the mandible's alveolar process. The longitudinal bundle emerges from the pterygomandibular raphe, which connects the buccinator's posterior fibres to the superior constrictor muscle.
The buccinator muscle is involved in the oral and pharyngeal phases of swallowing. It contracts gradually while closing the mouth and relaxes when the mouth opens, maintaining cheek tension and preventing injury. The muscle also helps to regulate parotid secretion, as small fibres are inserted into the distal portion of the parotid duct.

It compresses the cheek against the molar teeth
The buccinator muscle compresses the cheek against the molar teeth. It is a thin, quadrilateral muscle that forms the anterior part of the cheek or the lateral wall of the oral cavity. The muscle originates from the outer surfaces of the alveolar processes of the maxilla and mandible, corresponding to the three pairs of molar teeth. The superior part of the buccinator arises from the outer surface of the alveolar process of the maxilla, opposite the three maxillary molar teeth. The inferior part arises from the alveolar part of the mandible, opposite the three mandibular molar teeth.
The buccinator muscle has several important functions. Firstly, it helps to hold food in the mouth during chewing, preventing it from falling out. This is achieved by compressing the cheek against the molar teeth, which keeps the food bolus centred in the oral cavity. This action also prevents the cheeks from being bitten during mastication. Secondly, the buccinator muscle assists in playing wind instruments or whistling by allowing air to be expelled from the inflated vestibule or cheeks. This is particularly useful for activities such as playing a trumpet or suckling in neonates.
The buccinator muscle is the main muscle of the cheek, providing it with structure and tightness. It is deeper than the other facial muscles and is involved in several facial expressions. The muscle is innervated by the buccal branches of the facial nerve (CN VII) and receives arterial blood supply mainly from the buccal artery, a branch of the maxillary artery. The parotid duct, which carries saliva, pierces the buccinator muscle and enters the oral cavity adjacent to the second maxillary molar.

It is involved in mastication and facial expressions
The buccinator muscle is the main muscle of the cheek that provides it with structure and tightness. It is responsible for compressing the cheeks and expelling air between the lips, such as when blowing a trumpet. The buccinator muscle is also involved in mastication, or chewing, and holds food in the mouth while chewing. This prevents food from falling out of the mouth and stops the cheeks from being bitten during chewing.
The buccinator muscle is also important for facial expressions. It is involved in several facial expressions, including whistling, blowing a kiss, and sucking on a lemon. The act of compressing the cheeks can be the precursor to these facial expressions. For example, compressing the cheeks can be the first step in whistling, which requires a specific mouth shape to produce the desired sound.
The buccinator muscle is not typically considered an expressive muscle, as it is primarily used for chewing. However, because it intermingles with many other facial muscles, it contributes to various facial expressions. The buccinator muscle is one of the first muscles activated by sucking during infancy and continues to play a role in sucking movements throughout life.
The buccinator muscle also helps to regulate parotid secretion and contributes to parafunctional movements, such as bruxism (teeth grinding), finger-sucking, and thumb-sucking. Additionally, the buccinator muscle plays a role in the oral and pharyngeal phases of swallowing. It contracts gradually while closing the mouth and relaxes when the mouth opens, aiding in mandibular movements like protrusion and retrusion.

It helps prevent injury and maintain cheek tension
The buccinator muscle is a square, bilateral muscle situated deep within the adaptable cheek area. It is the main muscle of the cheek, providing it with structure and tightness. The buccinator muscle compresses the cheek against the molar teeth, which is important to keep the food bolus central in the oral cavity and to prevent the cheeks from being bitten during mastication. It also helps to expel air from the cheeks, as in blowing a trumpet or whistling.
The buccinator muscle is activated during mandibular movements like protrusion and retrusion, aiding in completing these actions. It also helps regulate parotid secretion and plays a role in the oral and pharyngeal phases of swallowing. The buccinator muscle contracts gradually while closing the mouth and relaxes when the mouth opens. These actions maintain cheek tension and prevent buccal mucosal injury.
The buccinator muscle is involved in several facial expressions, such as blowing a kiss, sucking on a lemon, or whistling. It is also involved in mastication and holding food in the mouth while chewing. Additionally, it helps prevent food from falling out of the mouth and can contribute to the appearance of lines, wrinkles, and sunken cheeks if not properly treated.
The buccinator muscle fibres originate from three areas, giving rise to three muscular bundles. Two of these bundles have a bony origin, with the maxillary bundle arising from the buccal portion of the maxilla's alveolar process and the mandibular bundle originating from the buccal portion of the mandible's alveolar process. The third bundle, the longitudinal bundle, emerges from the pterygomandibular raphe, connecting the buccinator's posterior fibres to the superior constrictor muscle.

It can be treated to prevent sunken cheeks
The buccinator muscle is the main muscle of the cheek, providing it with structure and tightness. It compresses the cheek against the molar teeth, helping to keep food in the mouth during chewing and preventing the cheeks from being bitten. The buccinator is also involved in several facial expressions, such as whistling, blowing kisses, and sucking on a lemon.
Sunken cheeks can occur due to various factors, including ageing, rapid weight loss, eating disorders, and chronic illnesses. While some people may not be concerned with the appearance of sunken cheeks, others may seek treatment to achieve a more youthful and less tired look. Here are some ways to treat sunken cheeks:
Surgical Treatments
Facelift surgery or facial fat grafting are considered the most effective and long-lasting treatments for sunken cheeks. Facial fat grafting involves collecting fat from other areas of the body through liposuction and injecting it into the cheeks to add volume. The results may take some time to appear as the body needs to heal and adjust. This procedure has a reduced risk of allergic reactions and can improve skin quality near the graft site.
Non-Surgical Treatments
Dermal fillers are a trusted and highly effective non-surgical approach to restoring volume and enhancing the cheeks. Fillers are typically made from hyaluronic acid, which provides hydration and plumps up the skin. They can be injected into the cheeks to add volume and definition, giving a fuller and more youthful appearance. Other materials used in dermal fillers include calcium hydroxylapatite, polymethylmethacrylate, and poly-L-lactic acid.
Skin Treatments
Professional skin treatments such as chemical peels and collagen induction therapy can help smoothen and thicken the skin. These treatments can be used alone or in combination with dermal fillers to enhance their effects. Additionally, at-home skincare routines with prescription anti-ageing products can improve skin elasticity and texture, reducing the appearance of sunken cheeks.
Lifestyle Changes
Maintaining a healthy lifestyle can help slow down the development of sunken cheeks. This includes eating nutritious foods, staying hydrated, getting adequate sleep, and avoiding smoking and nicotine products. Protecting the skin from harsh weather conditions can also help prevent and mitigate the effects of sunken cheeks.
