  2. 2.Acute Necrotizing Ulcerative Gingivitis (Anug)

    Acute necrotizing ulcerative gingivitis (ANUG) is a relatively rare infection of the gums. It's also known as "trench mouth", as it was discovered in a large number of soldiers in WWI that were stuck in trenches. The pain caused by ANUG is what makes it different from chronic periodontitis, and it requires treatment by professionals.

    Good prognosis with treatment. Without treatment, ANUG can become recurrent and chronic.

  3. 3.Burning Mouth Syndrome

    Burning mouth syndrome (BMS) is a chronic pain syndrome defined as having a burning pain or sensation in your mouth without a cause that can be found. It happens way more often in women (7 times more likely), typically during times of hormonal changes (just before or during menopause). While no one has identified the cause, it could have to do with the makeup of saliva, damage from dentures, tics or teeth grinding, infections, and even autoimmune diseases.

    23.8% have moderate improvement with treatment. 49% see no improvement. 18.9% get worse over time. 3% of people will have it go away on its own.

    Rarity:
    Common
    Top Symptoms:
    dry mouth, changed sense of taste, tongue pain, burning sensation in the mouth, moderate mouth pain
    Symptoms that always occur with burning mouth syndrome:
    burning sensation in the mouth, tongue pain

  4. 4.Dry Socket (Postextraction Alveolar Osteitis)

    Dry socket (or postextraction alveolar osteitis) is a common cause of severe pain after a dental extraction (tooth pull). It's known to be related to how the extraction was done, menstrual cycle, tobacco smoking, age, sex, and whether you have had an extraction before.

    You need to be seen by a dentist after initial treatment. Prognosis is good, though. If untreated, pain can last 10-40 days.

    Rarity:
    Ultra rare
    Top Symptoms:
    constant mouth pain, chronically bad breath, changed sense of taste, severe mouth pain, mouth pain at the site of a dental procedure

    mouth pain at the site of a dental procedure, constant mouth pain
    Urgency:
    Hospital emergency room
  5. 5.Cold Sore

    Cold sores (also called oral herpes or fever blisters), are viral infections of the mouth caused by the herpes virus type 1. You were probably infected very early in life as a child when an adult kissed you. The virus stays asleep (dormant) and causes infections every now and then after exposure to lots of sun or emotional/physical stress. It is contagious when an outbreak is happening, but treatment is limited unless you are immunocompromised.

    1-2 weeks. Natural healing process starts within 24 hours of the initial sore starting.

    Rarity:
    Uncommon
    Top Symptoms:
    mouth lesions, itchy mouth, pain on the outside of the lips, lip numbness, burning pain on the outside of the lips
