  1. 1.Low Calcium Level

    Hypocalcemia is a condition where there is not enough calcium in the blood. Calcium is a mineral contained in the blood, which helps the heart and other muscles function properly, and is needed to maintain strong teeth and bones.

    Problem should go away with home care within weeks.

  2. 2.Head and Neck Cancer

    There are five main types of head and neck cancer, which are all named according to the part of the body where they develop: laryngeal (voice box), nasal cavity and sinus, nasopharyngeal (air passage way behind the nose), oral (mouth), and salivary gland cancers. Most of these cancers are squamous cell carcinomas (SCCs), meaning they begin in the flat (squamous) cells that make up the thin surface layer of the structures in the head and neck.

    Head and neck cancers span different types of cancer with variable prognosis so a consultation with an oncologist is required to determine outlook.

  3. 3.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.

    Top Symptoms:

  4. 4.Perleche (Angular Cheilitis)

    Perleche (angular cheilitis) is inflammation of the corners of the mouth. It's typically caused by collection of moisture at the corners of the mouth, which allows for fungus, bacteria, or other organisms to infect the skin. This typically happens in children who mouth-breathe or thumb-suck, adults with poorly fitting dentures, or people with vitamin deficiencies, anorexia, or bulimia.

    Good prognosis with treatment. Relapses occur because you do not use the medication enough or the underlying cause isn't dealt with.

    pain in the corners of the mouth, corner of the mouth redness, spontaneous skin changes, mouth skin changes
