A Bone in the Chulent Cracked My Molar on Shabbat

Quick answer: If you crack a tooth on Shabbat and there is no swelling or bleeding, you can usually wait until Motzei Shabbat. Keep the tooth clean, chew on the other side, and avoid anything hot or cold. Swelling, fever or bleeding you cannot control is a different matter and needs help immediately.

The call

Shmuel, 46, from RBS Alef, bit down on what he assumed was a soft piece of potato in the chulent. It was a shard of flanken bone. He described the moment precisely: not a slow ache but one hard crack, and then a tooth that suddenly felt taller than the ones beside it.

For the rest of Shabbat he ate on his right side and rinsed with warm salt water. By Motzei Shabbat he had messaged us on WhatsApp, and he was in the chair the next morning.

What we found

The lower left first molar, the six-year molar that does most of the heavy chewing, carried a large old filling with only thin walls of enamel holding it together. The bone had loaded the tooth in exactly the wrong direction and sheared the inner cusp away from the rest.

Two findings told us the nerve was still healthy. Cold sensitivity was sharp but vanished within a second of removing the stimulus, and the tooth was not tender when tapped. That distinction matters more than the size of the break. A cracked tooth that reacts briefly is usually restorable. One that throbs for minutes afterwards, or wakes you at night, has generally taken the nerve with it.

What we did

We removed the loose fragment and the old filling, cleared the decay that had been working quietly underneath, and rebuilt the tooth with a bonded core. Then we prepared it for a full crown and fitted a temporary at the same visit. Shmuel walked out able to chew, which was his real worry: there was a bar mitzvah that week.

The permanent crown went on ten days later. We spent a few extra minutes adjusting the bite, because a tooth that takes the first hit every time you close is a tooth that will crack again.

The outcome

Eighteen months on the tooth is comfortable and the nerve never needed treating. Had he chewed on it for another month, the crack would very likely have travelled below the gum, and the conversation would have been about extraction rather than a crown.

What to do if this happens to you

1. Stop using that side. Every bite drives the crack deeper.
2. Rinse with warm salt water. Do not explore the break with your tongue or a toothpick.
3. Keep the fragment. It is rarely reattached on a back tooth, but on a front tooth it often can be.
4. Take painkillers if you need them — ibuprofen if you can, paracetamol if you cannot.
5. Call as soon as you are able. A cracked tooth is not usually a middle-of-the-night emergency, but it is a this-week problem, not a next-month one.
6. Go to urgent care instead if you have facial swelling, a fever, or you cannot open your mouth.
