hi i have a pain inside my mouth it’s on the left side it’s so painful goes through my lower teeth ican’t eat help
This could be due to any number of causes listed in the article below on mouth pain – http://www.healthhype.com/stomatodynia-causes-of-mouth-pain-tongue-palate-cheek-lips.html
This could range from cavities in the teeth, diseases of the gum and jaw bone, salivary glands, various infections and inflammatory conditions that affect the mouth. Pain on its own without any other signs and symptoms is difficult to diagnose and you should see your doctor and dentist as soon as possible.
Sometimes the pain can be referred from other areas and therefore the problem may not lie in the mouth itself. However, your description of the pain is typical of dental problems so speak to a dentist as soon as possible.
