Submaxillary gland pain and pressure pain are the typical symptoms of submandibular gland inflammation, which is a retrograde inflammation of the submandibular gland due to the obstruction and narrowing of the duct. Clinical manifestations are mainly pain and pressure pain in the submandibular gland, with purulent secretion overflowing from the mouth of the duct. The disease has a high incidence in adults and is mostly chronic in presentation. At present, there are more effective therapeutic drugs and methods, and the cure rate is high. Those who do not receive treatment in time and those who are not formally treated have poor efficacy, therefore, early treatment is the key, so what are the causes of submaxillary gland pain and pressure pain? The following is to give you an explanation. The causes of submandibular gland pain and pressure pain The reasons for the formation of salivary stone are multifaceted, mainly due to the submandibular gland is a plasma cell-based plasma mixed glands, the secretion of mucus content is higher than the parotid gland, and alkaline, containing calcium and phosphate concentration is also higher, so it is easy to occur inorganic salt deposition, coupled with the longest conduit, the diameter of the tube is only 2 ~ 4mm, the stroke is from the lower back to the anterior, so saliva is easy to stagnate in the duct, in addition, the conduit is easy to be in the duct, and the duct is also easy to be in the duct, and the duct is easy to be in the duct, and the duct is easy to be in the duct. In addition, the opening of the duct is large and located in the front of the floor of the mouth, which is not only easy to be damaged, but also easy for foreign objects to enter the duct, so it is very easy to form salivary stone and submandibular adenitis occurs. Since submandibular gland pain and pressure pain are often complicated with salivary stone, the key to prevention is to pay attention to oral hygiene and drink more phosphoric water to prevent the formation of salivary stone. Surgery should be considered for chronic submandibular inflammation if it is recurrent and ineffective.
