During Ramadan, bad breath is a common issue for many individuals due to reduced saliva production when they refrain from eating or drinking throughout the day. Dr. Abdullah Saleh, a dentist based in Borlänge, discusses why this happens and offers insights into maintaining oral hygiene during the fasting period. He emphasizes the importance of hydration and the use of oral rinses after iftar to combat the effects of fasting on breath. Additionally, he suggests that individuals incorporate certain foods that help freshen breath into their iftar meals, which can provide relief and promote better oral health during the holy month.
