What is Oral Candidiasis?
Oral candidiasis, also called oral candidosis or even oral thrush, is an infection caused by a fungus called Candida albicans. This fungus is present in the oral cavity of many of us, but in a saprophytic form, without causing any pathology.
It is estimated that around 50% of the healthy population has this fungus in the oral cavity, being this percentage even higher as the age of the person advances, which causes this pathology to be increasingly important due to a life expectancy that continues to increase.
However, the presence of this fungus in the mouth is usually as a commensal species, that is, although it lives inside us, it does so in a balanced way, in homeostasis, together with the rest of fungi and bacteria that are part of the oral microbiota and thus can be there without causing any type of pathology, damage or infection.
The problem arises when an overgrowth of this fungus Candida albicans occurs, so that it ceases to live as a commensal to become a pathogenic species and cause infection.
Symptoms of Oral Candidiasis
It is an opportunistic infection, that is, the fungus takes advantage of a situation of an immune system that for some reason is weaker, to grow and exert its pathogenic effect causing the infection. It is then when the first symptoms of candidiasis in the mouth appear: whitish plaques on the tongue and the rest of the oral cavity. All this is often accompanied by difficulty in swallowing and pain.
Candida infections may be accompanied by lesions such as:
Causes of Oral Candidiasis
There are different reasons why this fungus can cause candidiasis in the mouth:
Risk factors in oral candidiasis
Some factors that increase the risk of developing oral candidiasis are:
- Advanced age.
- Prolonged use of antibiotics.
- Weakened immune systems.
- Use of inhaled steroids.
- Uncontrolled diabetes.
- Pregnancy.
Diagnosis of oral candidiasis
Diagnosis of oral candidiasis is usually made by visual examination of the mouth and throat. In difficult cases, scrapings of the lesions may be taken for examination under a microscope.
Treatment of oral candidiasis
As it is a fungal infection, the most effective treatments are based on antifungal drugs such as nystatin, miconazole or fluconazole.
These drugs are usually applied in the form of oral suspension so that when administering it, try to keep it in the mouth as long as possible before swallowing the product. In this way, a longer time of direct contact between the drug and the fungus causing the infection is achieved.
If the patient also wears dentures, it is important that the dentures are washed or brushed using the drug to try to eliminate the presence of the fungus in the denture itself.
Treatment of oral candidiasis with probiotics
Probiotics are having a great boom in recent years. They are being used in Irritable Bowel Syndrome, in treatments for diarrhea, in intestinal discomfort. Part of the mechanism of action of probiotics is based on the displacement of the “good” bacteria of the organism (the probiotic) against pathogenic microorganisms.
In the case of oral candidiasis, one of the probiotics that have shown an improvement in the treatment of these fungi in the mouth is Bacillus clausii (1) where it was demonstrated that this probiotic reduces the signs and symptoms of this pathology when administered as an adjuvant to pharmacological treatment.
Other probiotics such as Lactobacillus paracasei and Lactobacillus rhamnosus, Lactobacillus reuteri have demonstrated their ability to reduce the presence of Candida by modifying oral pH or other mechanisms of action (2).
Some probiotics that we can find on the Internet with these probiotic species with activity against oral candidiasis are:
Home remedies for oral candidiasis
There are really no home remedies for oral candidiasis. If we are suffering from this disease, what we have to do is to treat it by administering antifungals and/or make use of a probiotic treatment as well.
However, we can take some “home” measures that can help to make this fungus disappear from the mouth:
- Take a couple of yogurts a day. The probiotic load of yogurt can be very helpful in reducing the infectious load produced by the fungus.
- Extreme oral hygiene, even changing toothbrushes more frequently.
- Avoid tobacco and alcohol.
- Generate more saliva by chewing cardamom seeds or with chewing gum.
- Try to maintain a healthy lifestyle, with a healthy diet.
It is important to keep in mind that these remedies help provide temporary relief, but do not replace proper medical or pharmacological treatment.
Prevention of oral candidiasis
To prevent oral candidiasis, it is important to maintain good oral hygiene. Some preventive measures include:
- Brush your teeth at least twice a day.
- Floss daily.
- Avoid excessive use of alcohol mouthwashes.
- Keep dentures clean and well adjusted.
- Avoid excessive consumption of sugar and yeast-rich foods.
Conclusion
Oral candidiasis is a fungal infection that affects the mouth and throat. It is caused by the overgrowth of Candida albicans. Common symptoms include velvety, whitish-white lesions, pain and difficulty swallowing.
It is important to seek appropriate treatment to relieve symptoms and prevent complications. Maintaining good oral hygiene and addressing underlying conditions are also key to avoiding oral thrush.
Frequently asked questions about oral candidiasis
Is oral candidiasis contagious?
