Crown or Filling — Which Do I Need?

You've got a cavity, or a tooth that's been twinging, and one dentist says filling, the internet says crown, and your wallet says "please be the filling." Here's how the decision actually works, including the honest gray zone where two good dentists can disagree, and how we handle it here.

When a filling is enough

A filling repairs a small-to-medium area of decay in a tooth that's still structurally sound. We remove the decayed portion, bond in tooth-colored composite, and the surrounding healthy enamel does the heavy lifting. If the decay hasn't undermined the walls of the tooth and there's no crack, a filling is the right call. It's faster, cheaper, and preserves the most natural tooth.

When a crown is needed

• Large decay. When a cavity has consumed a big share of the tooth, there isn't enough healthy structure left to hold a filling. A big filling in a hollowed-out tooth is a fracture waiting to happen.
• A cracked tooth. Fillings can't hold a cracked tooth together — a crown wraps the whole tooth and stops the crack from spreading down toward the root.
• After a root canal (usually on back teeth). Root-canal-treated molars become brittle, and a crown protects the investment you just made in saving the tooth.
• A tooth that keeps breaking. If a filling has been replaced twice and the tooth chipped again anyway, the tooth is telling you something.

The honest gray zone

Here's what most articles won't say: there's a real middle ground — a medium-large cavity, an old silver filling with a hairline crack next to it — where a filling might hold for years, and a crown is the safer long-term bet. Two ethical dentists can look at that tooth and recommend differently. What matters is that the recommendation is explained, not just handed down.

At our office the decision works like this: we put the intraoral camera photo of your actual tooth on the screen and show you what we see — the decay, the crack lines, how much healthy structure remains. Our philosophy is conservative-first: if a filling has a fair chance of lasting, we'll offer it, tell you the risk plainly, and let you choose. Nobody here gets paid more for talking you into a crown.

What each one costs

Treatment	Typical Salem range	At East Salem Dental
Tooth-colored filling	$150–400	$40–120 (by size)
Porcelain crown	$1,200–1,600	$900–1,300

Our fees are set about 20% below the typical Salem office. That's deliberate, across every service. Most PPO plans cover fillings at 70–80% and crowns at 50%, so a crown often lands at $450–650 out of pocket with insurance. OHP covers fillings outright and crowns in limited situations; we verify your coverage for free before anything starts, and every price goes in writing first.

The in-between option: onlays

Sometimes the honest answer is neither a filling nor a full crown. An onlay (sometimes called a partial crown) covers just the damaged portion of the chewing surface, keeping more of your natural tooth than a crown while giving more protection than a filling. It's not right for every tooth. It needs enough sound structure to bond to, but when it fits, it splits the difference in both coverage and cost. If your tooth is a candidate, we'll show you all three options side by side rather than jumping straight to the most expensive one.

What happens if you wait

Decay doesn't pause while you think it over. A $40–120 filling that waits a year often becomes a $900+ crown; a crown-sized problem that waits becomes a root canal plus crown, or an extraction. The pattern is brutally consistent: every stage of waiting roughly doubles the cost and shrinks your options. If money is the reason you're waiting, say so. We have 0% payment plans and a membership program built for exactly that conversation.
