One of the five pillars of Islam is fasting. During the Holy month of Ramadan, Muslims from all over the world forgo eating, drinking, smoking, and all other physical needs from dawn to sunset. Fasting teaches self-restraint, while cleansing the mind and body.
Healthwise, studies have shown that fasting has many positive effects on general health, including glycemic control, cholesterol, weight loss, blood pressure and even advantageous changes in the gut microbiome.
Meticulous oral care is essential while fasting because not paying extra attention to your oral health during Ramadan can lead to issues such as dental cavities or even gum disease.
If you haven’t been to your dental professional in a while, have a dental checkup and dental hygiene appointment before you begin fasting, to help eliminate any tooth problems which may occur during Ramadan.
Plan a routine for eating and sleeping. It is also a good idea to schedule your oral hygiene routines so that you can brush for two minutes and floss before sleeping, as well as at one other time during the hours of darkness. Wait for at least half an hour after eating, before brushing your teeth so that the enamel can remineralize.
Bad breath or halitosis is the most common side-effect of fasting. Not eating and drinking anything for a long time causes dehydration of the mouth, resulting in reduced saliva, which enables bacteria responsible for bad breath to build up on the teeth, gums, and tongue.
