Our saliva plays an important role in protecting our mouth and decreasing bacterial growth. When fasting, our saliva flow is reduced, and therefore, we have less protection against the oral bacteria that can cause bad breath (or halitosis). When you break your fast, your salivary glands will begin to stimulate again and fight against these bacteria.
Oral care tips during non-fasting hours
During non-fasting hours, it is extremely important to resume your oral hygiene routine.
- Brush for 2-3 minutes with a fluoride toothpaste after iftar and suhoor to reduce plaque buildup.
- Use interdental aids like floss and interdental brushes daily to clean areas in between your teeth that your toothbrush can’t reach.
- Use a tongue scraper to reduce the buildup of oral bacteria on your tongue and keep your mouth healthy.
Caring for your teeth and gums should not take the backseat during Ramadan.

Food tips on preventing bad breath and dehydration
- When breaking your fast, avoid foods which cause bad breath such as onions, garlic and spices.
- Drink at least 2-3 litres of water per day to keep yourself hydrated and help wash away food particles.
- Try to avoid caffeinated drinks like tea and coffee as they have diuretic effects.
- Try to stay away from food with high levels of salt and sugar to avoid dehydration.
Other oral care tips
- After breaking your fast, it is important to wait 30 - 60 minutes before you brush your teeth to give your saliva a chance to naturally wash away any food particles and allow time for your mouth to return to its normal PH level. This is to avoid acidic foods from damaging the enamel when it is in its weakened state.
- It is important to visit your dentist and hygienist regularly to have a tailored dental plan to suit your specific needs.
Caring for your teeth and gums should not take the backseat during Ramadan. You may need to change the timing of your oral care routine, but the basics remain the same.
