An Almond at Kiddush Sheared the Side Off My Tooth

Quick answer: When a cusp shears cleanly off a back tooth and there is no pain, it usually means the fracture stayed above the nerve. That is good news, but the tooth is now unsupported and needs covering before the next bite takes the rest of it.

The call

Chana, 57, from Mishkafayim, was standing at kiddush when she bit into a marcona almond. Something gave, and she found a piece of tooth in her hand. No pain, no bleeding, no drama — she finished her cake and phoned us on Sunday morning.

Her concern was practical. She was flying to a granddaughter's wedding in ten days and did not want to be dealing with a temporary crown at an airport.

What we found

The lower right first molar had lost its entire lingual cusp — the inside wall, tongue side — which had sheared away at gum level. The remaining tooth looked like a shell with a large old composite filling occupying the middle.

Why there was no pain: the fracture had run outside the pulp chamber, taking the wall but not reaching the nerve. Cold testing gave a normal, brief response. Nothing was tender to tapping. The x-ray showed no infection at the root tips.

The fracture line finished a whisker above the gum on the tongue side, which is the difference between a straightforward crown and a much longer conversation about crown lengthening or extraction. We probed carefully around the whole margin to confirm.

What we did

A same-day crown. We removed the old composite and the decay under it, shaped the remaining tooth, took a digital scan, and milled a ceramic crown in the practice while she waited. Fitted, adjusted and cemented the same afternoon.

For a case like this, a single-visit crown is genuinely the better clinical option and not just a convenience. A tooth missing an entire wall is vulnerable in the two weeks between preparation and fitting. Temporary crowns on such teeth come loose, and every day the tooth spends flexing under a plastic temporary is a day the crack can extend.

We also checked her bite carefully in lateral movements. The cusp that broke was taking the full guiding load when she chewed sideways, which is very likely why it went first.

The outcome

She flew to the wedding with a permanent crown and no restrictions. At her check-up eight months later the tooth was symptom-free and the gum around the margin was healthy.

We identified two more heavily filled molars with similar unsupported cusps and have since protected both, electively, at times that suited her.

What to do if this happens to you

1. Keep the fragment to show the dentist — the shape tells us how the tooth failed.
2. Chew on the other side. An unsupported wall breaks again quickly.
3. Watch for sharp edges cutting the tongue; sugar-free gum is a reasonable overnight fix.
4. Do not assume no pain means no urgency. The nerve is fine, but the tooth is not.
5. Ask whether the fracture reaches below the gum. That single question determines the treatment plan.
6. If you are travelling, say so at the first call. It changes what we recommend.
