Hi. I have a really bad tooth ache on the left side of my jaw but cant seem to pin point a specific tooth. What hurts is the last 4 teeth on the top and the bottom, like all of them. The pain is like a constant ache that comes and goes and when I clench my teeth reasonably hard, it isnt excruciating but it does hurt those teeth more. It kind of feels like Ive tried to untwist the cap off of a bottle with my teeth but I know that I havent. This has never happened before. I dont have outstanding oral hygeine, my gums are red in some places but Im working on brushing twice a day and getting habits up to standard. On my right side, up the top one of the corners of my wisdom tooth has just broken the skin and although the others havent I can feel them through the gum on my left side, top and bottom. There isnt much room at the back of my gums and I fear I may have an infection or it could be my wisdom not having enough room to come through. I am 20 years old.

Hello pt-Dental Caries (Teeth Cavities) Cause Toothache and Jaw Pain tooth cavity occurs as a result of a combination of factors. Food particles get trapped on and between the teeth after eating. Along with mucus, dead epithelial cells (from the mouth lining) and bacteria, a thin soft film, known as plaque coats the teeth. This provides the ideal medium for oral bacteria to feed upon food debris. Bacteria like Mutant streptococci and related groups, break down food particles and produce lactic acid as a byproduct. It is this lactic acid that is responsible for eroding tooth enamel and causing tooth cavities. Food + Mucus + Dead Cells + Bacteria = Soft Plaque (within 24 hours after brushing)Soft Plaque + Calcium +Phosphates + Other Compounds = Hard Plaque (within 72 hours of soft plaque formation)Left untreated, the lactic acid will continue to erode the enamel and dentin and cause irritation of the nerve which is experienced as a toothache. A toothache (painful and tender tooth) is a late symptom of an untreated tooth cavity. Toothaches may also be caused by an infection, injury or the absence of a tooth. Jaw pain may also occur as a result of a dental cavity as the nerve supply of a tooth follows a path around or near the jaw. However, jaw pain should not always be mistaken for a dental cavity as there can be other causes like TMJ dysfunction (temporomandibular joint syn Chat Doctor. Jaw pain may precede, be accompanied by or follow after a toothache and this jaw pain may often radiate around the side of the affected tooth. This jaw pain can vary from dull pain in the early stages to severe throbbing pain with tenderness around the affected tooth.
