Back Tooth Crowns: Complete FAQ

Why Do Back Teeth Need Crowns?

Back teeth often need crowns after a large cavity or a deep filling has removed too much of the natural tooth. A tooth that has had root canal treatment may also need extra protection because it’s more likely to fracture.

The crown covers the remaining tooth and spreads chewing pressure more safely. It also restores the tooth’s shape, so eating doesn’t feel like you’re working around one weird spot in your mouth.

What Happens During a Crown Procedure?

First, the dentist numbs the area. The damaged part of the tooth is removed, and some enamel is shaped so the crown can fit over it properly. An impression or digital scan is then used to make the permanent crown.

You’ll usually wear a temporary crown while the final one is being made. Try not to treat that temporary tooth like it’s indestructible. It isn’t.

Will Getting a Back Tooth Crown Hurt?

During the procedure, you shouldn’t feel pain because the tooth and surrounding area are numbed. Afterward, mild tenderness or sensitivity is fairly common, especially when you bite down.

Severe pain isn’t something to simply put up with. Call your dentist if the pain gets worse instead of better or your bite feels noticeably uneven.

How Long Does a Back Tooth Crown Last?

A few habits make a difference:

• Night grinding can put serious pressure on a crown, especially if you wake up with sore jaw muscles.

• Good brushing matters, and cleaning around the gumline keeps the tooth underneath from developing new decay.

• Hard foods aren’t automatically forbidden, though biting directly on very hard objects is asking for trouble.

What Type of Crown Is Best for a Back Tooth?

For molars, strength usually matters more than appearance. Zirconia crowns are popular because they’re strong and look fairly natural. Porcelain-fused options are also used, depending on the tooth and your dentist’s preference.

Personally, I’d put durability first for a back molar. Nobody sees your last molar when you laugh, but you definitely notice it when chewing stops feeling normal.

Can a Crown Get a Cavity?

The crown itself can’t decay, but the natural tooth underneath it still can. That’s why the edge where the crown meets your tooth deserves attention. If plaque sits there for long enough, decay can start around the crown.

And if your dentist recommends a crown for a badly damaged back tooth, putting it off for months usually isn’t a clever money-saving trick. A cracked tooth can turn a straightforward repair into a much bigger problem.
