UNAIR NEWS – Fasting during Ramadan is a fundamental religious obligation for Muslims worldwide. Beyond its spiritual significance, fasting offers numerous health benefits. However, one common issue many individuals face is bad breath, which can be particularly bothersome during social interactions and religious activities.
Prof. Dr. Theresia Indah Budhy, drg., M.Kes., Sp.PMMF, a professor of Oral and Maxillofacial Pathology at Universitas Airlangga (UNAIR), provided expert advice on maintaining fresh breath while fasting. She explained that a key cause of bad breath is the decrease in saliva production, which naturally occurs when abstaining from food and drink.

“Saliva contains proteins that regulate the pH balance, support the microbiome, and aid metabolism. When saliva production declines, metabolic activity slows, pH levels drop, and microbial imbalances develop in the mouth. These changes lead to the release of compounds that cause bad breath,” she explained.
Prof. Theresia Indah Budhy added that leftover food particles from the pre-dawn meal can further contribute to bad breath. Additionally, consuming sugary foods can lower the mouth’s pH, disrupting its natural microbial balance.
How to maintain fresh breath
To reduce the risk of bad breath, she recommended brushing teeth thoroughly after pre-dawn meal. She also advised against consuming foods high in sugar or sticky foods that adhere to teeth. Instead, she suggested choosing fiber-rich foods with high water content, which can help maintain oral hygiene.
“Regular dental check-ups are also essential. If you have cavities, seek treatment. Additionally, if you have food allergies, avoid those foods during fasting and opt for meals rich in fiber and water,” she advised.
Foods to avoid
Prof. Budhy also highlighted certain foods that fasting individuals should steer clear of. “Some foods can disrupt the oral microbiome and metabolic processes while fasting. These include high-sugar foods, excessively salty or savory dishes, deep-fried foods with high saturated fat content, and carbonated or alcoholic beverages,” she warned.
Finally, she emphasized the importance of maintaining a stable metabolism during fasting. To achieve this, she encouraged individuals to maintain a balanced diet and continue their usual activities. Light exercise, such as walking, is particularly beneficial. She also recommended incorporating probiotics and prebiotics into the diet to support digestive and overall health.
