Oral thrush is an infection which is caused by excessive growth of the fungus Candida, which often affects the tongue first with large white spots or patches, then spreads to the insides of the cheeks, gums and roof of the mouth. To cure this infection, you will need a antifungal treatment prescribed by your doctor in order to fight this yeast infection and fully recover. In the following OneHowTo article you'll find some simple steps and health recommendations that can be taken so you can learn how to prevent oral thrush.

Steps to follow:


Firstly, we need to tell you that there is no method that can prevent oral thrush 100%, but it is possible to adopt certain measures that may reduce the risk of catching it. This type of infection caused by micro-organisms often affects:

  • Babies and elderly people.
  • People with weakened immune systems, as is the case with those living with HIV, diabetes or cancer.
  • People with poor diets.
  • People who are taking antibiotics.
  • People who are experiencing hormone changes, such as pregnant women, women on their periods or going through menopause.
  • People who suffer from dry mouth or who wear dentures.

As mentioned earlier, those with a weakened immune system are more vulnerable to developing oral thrush, so it is important that they maintain a healthy diet everyday, which needs to be especially high in vitamins A, C, and E, and minerals such as calcium, zinc and iron, the latter being essential to prevent diseases affecting your body's defenses such as anemia. In addition to these nutrients, it is also important to have a balanced diet, not missing a particular food group. And, of course, together with a good diet, you must ensure that you get enough sleep, physical exercise and do relaxing activities to help combat stress, because this is one of the emotional conditions that weaken the immune system.
