Hello there ,
Thanks for writing your query,
Prolonged use of certain antibiotics are associated with recurrent development of oral thrush
or dry mouth makes the oral cavity susceptible to any kind of infection, bacterial or fungal including oral candidiasis
I would suggest you to consult your treating doctor for a detailed clinical examination. If you also have be suffering with xerostomia, you may discuss with your physician and talk to him about the drug induced xerostomia and thereby oral thrush.
The following are a few simple treatments of oral thrush:
1. You can do symptomatic treatment at home by regular mouth rinsing with antiseptic mouthwash like betadine or chlorhexidine
or simply with lukewarm saline water.
2. Maintain good oral hygiene
, drink lot of water and keep yourself hydrated , avoid alcohol, carbonated drinks and smoking as it may worsen the condition.
Get well soon ,
i hope this helps ,
