During fasting, it is not unexpected that the mouth becomes dry. This naturally results in malodor.Poor oral hygiene care will indeed make it even worse.A practical way of overcomeing it is to ensure patients, even during fasting,to still brush their teeth and floss as usual to keep the mouth feeling fresh and clean.Mouthrinsing is also permissible as long as patients don't overdo it! Avoid alcohol-based mouthwash as it will dry out the mouth.Drinking plenty of water and fruits during the night or at sahur/sehri can help to keep the body stay hydrated and healthy.It is also worthy to examine the whole mouth for any dental or oral manifestations that may be contributing to the malodor such like dental caries,infection and/or discharges.
