Oral thrush

Oral thrush (oral candiasis)is an infection caused by a type of fungus called Candida.

It causes white patches (plaques) to develop in the mouth. You may experience a loss of taste or an unpleasant taste in your mouth. It can also be painful, making eating and drinking difficult.

Median rhomboid glossitis is a condition that can affect your tongue if you have oral thrush. It causes a red, smooth patch or lump to develop in the middle of the top part of your tongue, whichcan be sore.

You're more likely to develop oral thrush if you:

  • have recently taken antibiotics
  • take inhaled corticosteroid medication for asthma
  • wear dentures , particularly if they don't fit properly
  • have poor oral hygiene
  • have a medical condition, such as diabetes
  • have a dry mouth , either because of a medical condition or a medication you're taking
  • smoke
  • have a weakened immune system as a result of having chemotherapy or radiotherapy treatment for cancer

See your GP if you think you have oral thrush. If it's left untreated, the symptoms will persist and your mouth will continue to be uncomfortable.

Oral thrush is treated with antifungal medicines , often in the form of a gel or liquid that you apply directly to the inside of your mouth.

You'll usually need to use it several times a day for around 7 to 14 days.
