Differential Diagnosis for Sharp Pain in Mouth that Calms Down with Water

  • Single Most Likely Diagnosis
    • Dentinal hypersensitivity: This condition is characterized by sharp pain in response to stimuli such as temperature changes, sweet or sour tastes, and pressure. Holding water in the mouth may temporarily alleviate the pain by reducing the stimuli that trigger the pain, such as temperature changes or air exposure.
  • Other Likely Diagnoses
    • Tooth decay or cavity: Sharp pain can be a symptom of advanced tooth decay, especially if the decay has reached the pulp. The pain may be temporarily relieved by holding water in the mouth, which can help to reduce bacterial activity and acid production.
    • Cracked tooth syndrome: A cracked tooth can cause sharp pain when chewing or biting, and the pain may be relieved by holding water in the mouth, which can help to reduce the pressure on the cracked tooth.
    • Gingivitis or periodontitis: Inflammation of the gums can cause sharp pain, especially if the gums are sensitive or if there are abscesses present. Holding water in the mouth may help to reduce the pain by keeping the area clean and reducing bacterial activity.
  • Do Not Miss Diagnoses
    • Dental abscess: A dental abscess is a serious condition that requires prompt treatment. While it may not be the most likely diagnosis, it is crucial to rule out an abscess, as it can lead to serious complications such as sepsis or spread of infection to other parts of the body.
    • Oral cancer: Although rare, oral cancer can cause sharp pain in the mouth, and it is essential to rule out this diagnosis, especially in patients with risk factors such as smoking or a family history of cancer.
  • Rare Diagnoses
    • Erosion or abrasion of tooth enamel: While not as common, erosion or abrasion of tooth enamel can cause sharp pain, especially if the dentin is exposed. This condition may be relieved by holding water in the mouth, which can help to reduce the stimuli that trigger the pain.
    • Burning mouth syndrome: This condition is characterized by a burning sensation in the mouth, but some patients may experience sharp pain. The pain may be relieved by holding water in the mouth, which can help to reduce the burning sensation.
