Fights Fungus Candida albicans is a type of fungus that commonly causes dental issues like plaque overgrowth, gum infections and root canal infections . Castor oil has antifungal properties and may help fight off Candida, keeping the mouth healthy.
One test-tube study found that castor oil eliminated Candida albicans from contaminated human tooth roots.
Castor oil may also help treat denture-related stomatitis, a painful condition thought to be caused by Candida overgrowth. This is a common issue in elderly people who wear dentures.
A study in 30 elderly people with denture-related stomatitis showed that treatment with castor oil led to improvements in the clinical signs of stomatitis, including inflammation.
Another study found that brushing with and soaking dentures in a solution containing castor oil led to significant reductions in Candida in elderly people who wore dentures.
SUMMARY: Several studies have shown that castor oil may help fight fungal infections in the mouth caused by Candida albicans.
