A Filling From 1994 Finally Split the Tooth

Quick answer: A very old filling that finally breaks the tooth around it is not automatically an extraction. If enough solid root remains above the bone, the tooth can often be rebuilt — but it takes more than one appointment and an honest conversation about cost.

The call

Ovadia, 63, from the merkaz in Old Beit Shemesh, came in with a lower left molar that had broken down over several months. He had been told twice, elsewhere, that it needed to come out. He was not arguing with that, but he wanted one more opinion before losing a tooth he had had since he was a boy.

The filling had been placed in Israel in 1994. It had outlasted two dentists.

What we found

The amalgam was still sitting there, largely intact, in a tooth that had crumbled away around it. The cheek-side wall had gone completely, down to just below the gum. The tongue-side wall was cracked but standing. There was decay under both.

The tooth was tender to pressure and had been aching intermittently at night. Cold produced almost no response — the nerve was dying or already dead. The x-ray showed a small dark area at one root tip, confirming a chronic low-grade infection.

So the question was not whether the tooth was damaged. It was whether enough sound tooth remained above the bone to hold a crown. We measured. The break on the cheek side ran about one and a half millimetres below the gum margin but was still above the bone crest, and the root itself was long, with good bone support and no gum pockets.

That is a rebuildable tooth. Had the fracture reached the bone, or had the root been short and mobile, I would have agreed with the previous two opinions.

What we did

Three stages over ten weeks.

First, a root canal — necessary in any case because the nerve was dead and infected. Two visits, with a dressing in between to settle the infection.

Second, minor crown lengthening. A small surgical procedure to reshape the gum and a fraction of bone on the cheek side, exposing enough solid tooth for a crown margin to seal against. Without this step, the crown would sit on soft tissue and fail within a couple of years.

Third, after six weeks of healing, a post, a core and a full crown.

I was direct with him about the arithmetic. Three procedures cost meaningfully more than an extraction. It is less than an implant, and it keeps his own root and his own bone. He chose to keep the tooth.

The outcome

Four years on the crown is sound, the x-ray shows the infection at the root tip has healed, and the gum margin is stable. He chews on that side without thinking about it.

What to do if this happens to you

1. Get a second opinion before an extraction, particularly if nobody has measured how far the break goes.
2. Ask specifically: is there enough sound tooth above the bone level?
3. Ask about the root, not just the crown. A long, well-supported root is worth rebuilding around.
4. Do not chew on it while you decide.
5. Ask for the full cost of the whole sequence up front, not visit by visit.
6. Get the timeline in writing. These plans take weeks, and knowing that in advance prevents frustration.
