First, dental caries: the occurrence of dental caries can also lead to toothache. Initial dental caries are usually asymptomatic. When the cavity becomes bigger and deeper, toothache will appear when eating, and eating sweets or foods that are too cold or too hot will aggravate the pain. At this time, you can brush your teeth with warm water, but the effective treatment should be filling your teeth.
Second, pulpitis: mostly caused by deep caries, or caused by chemical drugs or temperature stimulation. The pain is spontaneous and paroxysmal, and there may be cold and hot stimulation pain and tapping pain. The radical method is to grind the pulp cavity with anvil under local anesthesia for dental pulp treatment.
Third, periapical periodontitis: pulpitis spread to the root canal orifice, causing inflammation of the tissue around the root tip. It is characterized by persistent toothache. The affected teeth have a sense of elongation, tenderness and tenderness, and can't bite food. At this time, you can take anti-inflammatory painkillers and do root canal treatment after anti-inflammation.
Fourth, tooth trauma: If you accidentally fall, bruise or bite the sand while eating, your teeth will break or crack, causing toothache. You can take anti-inflammatory drugs and painkillers first.
Fifth, pericoronitis of wisdom teeth: wisdom teeth are difficult to erupt (impacted), and poor oral hygiene leads to inflammation and swelling of tissues around the crown.
