Top 10 Mouth Pain Causes

  1. 1.Acute Bacterial Sinusitis

    Acute bacterial sinusitis occurs when the sinuses become infected and, in turn, inflamed, which causes pain and other symptoms. The sinuses are air-filled cavities in the face that are generally clean and empty but when sick collect excess mucus and can become infected.

    You should visit a physician or urgent care facility in the next day or two. It’s likely your sinus infection is caused by a bacterial infection, which requires treatment with antibiotics. In the mean time, ibuprofen or acetaminophen can be taken to help with pain & fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, cough, muscle aches, sore throat
    Symptoms that always occur with acute bacterial sinusitis:
    sinusitis symptoms
    Symptoms that never occur with acute bacterial sinusitis:
    clear runny nose, being severely ill
    Urgency:
    Primary care doctor
  2. 2.Acute Viral Sinusitis

    Sinusitis is an inflammation of the sinus spaces behind the nose and cheeks. These spaces produce mucus, which drains into the nose. If the nose is swollen or if the mucus does not drain, this can block the sinuses and cause pain or infection.

    You can treat your symptoms at home using ibuprofen (for pain) and Tylenol (for a fever). Antibiotics for this diagnosis are not helpful because this is likely a viral infection.

    Rarity:
    Common
    Top Symptoms:
    headache, cough, sore throat, sinusitis symptoms, muscle aches
    Symptoms that always occur with acute viral sinusitis:

    Symptoms that never occur with acute viral sinusitis:
    being severely ill
    Urgency:
    Self-treatment
  3. 3.Temporomandibiular Joint (Tmj) Dysfunction Disorder

    The temporomandibular joint (TMJ) is located in front of the ear, and it connects the jaw to the side of the head. Temporomandibular disorder (TMD) is a painful condition which can be caused by excess tension in jaw mucles, faulty alignment between upper and lower teeth, arthritis in the joint, or injury of the jaw or face.

    You should visit your primary care physician. This is a complex condition to treat, because the causes are not always clear. Treatment may include resting the jaw with a soft diet, pain medications, and physical therapy.

    Rarity:
    Common
    Top Symptoms:
    dizziness, history of headaches, pain, restricted movement, and clicking sounds from jaw, pain in the back of the neck, jaw pain
    Symptoms that always occur with temporomandibiular joint (tmj) dysfunction disorder:
    pain, restricted movement, and clicking sounds from jaw
    Urgency:
    Primary care doctor
  4. 4.Common Cold

    The common cold is a viral infection of the upper respiratory tract.

    The common cold is treated symptomatically. Since this is a viral infection, antibiotics are not effective. You can safely treat the symptoms of this condition with over-the-counter pain relievers, decongestants, antihistamines & cough medicines.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, cough, sore throat, congestion
    Symptoms that never occur with common cold:
    being severely ill, severe muscle aches, rash, severe headache
    Urgency:
    Self-treatment
  5. 5.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.

    You should go to the nearest dentist as soon as possible, or to an urgent care if one is not open at this hour. There, you will be given antibiotics and mouth wash to relieve the pain. You should definitely see a dentist if you go to an urgent care first. The dentist will remove any dead gum tissue to promote healing and help reduce pain.

    Rarity:
    Rare
    Top Symptoms:
    bleeding gums, chronically bad breath, gum pain, severe mouth pain, gum redness
    Urgency:
    In-person visit

  6. 6.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.

    You can safely stay home or try some minor treatments. As a viral infection, it will go away on its own without antibiotics. Balm mint cream (1%) or topical rhubarb-sage cream may improve symptoms, but it's not standard treatment.

    Rarity:
    Uncommon
    Top Symptoms:
    mouth lesions, pain on the outside of the lips, itchy mouth, burning pain on the outside of the lips, lip numbness
    Symptoms that always occur with cold sore:
    mouth lesions
    Urgency:
    Self-treatment
  7. 7.Gingivitis

    Gingivitis is the infection of the gums surrounding the teeth. It is caused by plaque and/or tartar that has built up on your teeth. Plaque is a sticky layer of gunk made by food particles, mucus, and bacteria. After a while, plaque hardens to become tartar (or calculus). Plaque and tartar at the bottom of the teeth causes the gums to become irritated and infected.

    You should go to the nearest dentist in the next few weeks. There, the dentist or dental hygenist will clean your teeth, getting rid of that nasty plaque/tartar. Once cleaned, you should rinse your mouth twice-a-day with chlorhexidine 0.12% oral rinse (PerioGard) or half-strength hydrogen peroxide. Flossing and brushing your teeth are also essential.

    Rarity:
    Uncommon
    Top Symptoms:
    bleeding gums, gum pain, gum swelling, gum redness
    Urgency:
    Primary care doctor
  8. 8.Influenza

    Influenza, or Flu, is an infection of the airway caused by the flu virus, which passes through the air and enters the body through the nose or mouth. The symptoms are similar to those of a cold, but the flu is usually more serious.

    If your flu-like symptoms are existing for less than 48 hours, it might be helpful to seek care by telephone or in a walk-in-clinic to get a course of oseltamivir (Tamiflu). Most people will get better on their own by drinking lots of fluids and taking an over-the-counter medication such as acetominophen (Tylenol) to help with aches or fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, cough, muscle aches
    Symptoms that never occur with influenza:
    headache resulting from a head injury
    Urgency:
    Phone call or in-person visit
  9. 9.Strep Throat Requiring Throat Swab

    Strep throat is a bacterial throat infection that can make the throat feel sore and scratchy. Only a small portion of sore throats are the result of strep throat. And, if you do not show enough signs of a true strep throat, testing may be needed before treatment is begun.

    You should visit your primary care physician within the next 24 hours, where a diagnosis can be made via a "rapid antigen test" (it's a throat swab). Treatment with simple antibiotics would be given only if the test is positive. It is important to get treatment, however, because of the possibility of getting a disease called "rheumatic fever" after the strep throat infection.

    Rarity:
    Common
    Top Symptoms:
    fatigue, nausea, sore throat, fever, rash
    Symptoms that always occur with strep throat requiring throat swab:
    sore throat
    Symptoms that never occur with strep throat requiring throat swab:
    general weakness
    Urgency:
    Primary care doctor
  10. 10.Viral (Rotavirus) Infection

    Rotavirus is a virus that causes an infection of the gut, known as gastroenteritis. Symptoms include diarrhea, vomiting and fever. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids to replace what is lost with diarrhea. Eat as normally as possible. If symptoms of dehydration occur, or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, nausea, abdominal pain (stomach ache), headache, loss of appetite
    Symptoms that always occur with viral (rotavirus) infection:
    hidden: gastroenteritis symptoms
    Symptoms that never occur with viral (rotavirus) infection:
    constipation, tarry stool
    Urgency:
    Self-treatment
