Oral thrush in adults - Symptoms 

Symptoms of oral thrush in adults 

Symptoms of oral thrush can include:

  • sore, white patches (plaques) in the mouth that can be wiped off
  • a painful, burning sensation on the tongue
  • an unpleasant taste in the mouth that can be bitter or salty
  • redness and soreness on the inside of the mouth and throat
  • cracks at the corners of the mouth (angular cheilitis)
  • difficulty swallowing


If you wear dentures and have oral thrush, you may develop sore, red areas in your mouth where the dentures have been. This is known as denture stomatitis and can make wearing dentures uncomfortable.

When to seek medical advice

Speak to your GP if you develop symptoms of oral thrush. If left untreated, symptoms will persist and your mouth will continue to feel uncomfortable.
