Caries can cause toothache

Caries can cause toothache. This is because when the caries develops to a certain depth and reaches or approaches the pulp, the bacteria in the caries cavity can enter the pulp cavity directly or through the dentin tubules and cause pulpitis.

Pulpitis caused by toothache is very difficult to bear, in the outside world without stimulation, it can produce severe pain, pain is intermittent. Most patients have more pain when they sleep at night. This is because the head is in a lower position when they are lying than when they are standing, and the pulp cavity is more easily congested, so that the pressure in the pulp cavity increases and oppresses the nerves, so the pain is more serious. Hot and cold stimulation can aggravate toothache. When suffering from pulpitis, pain often radiates along the trigeminal nerve distribution area to the upper and lower teeth on the same side and the head and face, so patients often have symptoms of half side headache and temple pain. Because the nerve endings in the pulp have only pain receptors but no localization receptors, the patients often can not distinguish which tooth is the diseased tooth, sometimes the upper toothache is the lower toothache.

If the caries develops into pulpitis, then the pain becomes more intense, showing jumping pain. The hot stimulation can aggravate it, while the cold stimulation can relieve the pain. This kind of patients often like to have a cold water. When it comes to apicitis, the patient feels his teeth grow tall and dare not bite with them.
