Can I go to the dentist while fasting?

What usually doesn't break the fast

• Check-ups and X-rays. Nothing enters your stomach.
• Local anaesthetic injections in the gum. Most contemporary scholars say injections that aren't nutrition don't break the fast.
• Cleaning, fillings and polishing, as long as you spit out the water and the suction does its job.
• A taste that stays in your mouth after treatment.

This is the same principle as rinsing your mouth in wudu. The Prophet ﷺ only told fasting people not to overdo rinsing, so that water doesn't go down the throat (Sunan Abi Dawud 2366). See also Can I brush my teeth while fasting?

What can break it

Deliberately swallowing water, blood or anything from the treatment breaks the fast. If a small amount slips down by accident, scholars differ: Hanafi and Maliki scholars generally say you make up the day, while many Shafi'i and Hanbali scholars excuse an accident you tried to avoid. Tiny traces mixed into your saliva that you can't control are forgiven. See Does swallowing my spit break my fast?

Bleeding gums or a tooth extraction don't break the fast by themselves, as long as you spit the blood out. General anaesthetic or sedation is a different matter and many scholars say it's better done on a non-fasting day.

When it's fine not to fast

A painful abscess, an extraction or a root canal can leave you needing painkillers, antibiotics or a drink. Illness is a valid reason not to fast, and you make the day up later.

Follow your dentist's advice about medication and recovery. While you're recovering, you might find comfort in a short dua. See What dua can I say when I'm sick?

Practical tips for your appointment

• Book routine visits after iftar or outside Ramadan when you can.
• Tell the dentist you're fasting so they use good suction and avoid rinses you'd swallow.
• Tilt your head slightly forward and spit fully.
• Ask whether the work can wait a few weeks if it isn't urgent.
