Can a Tooth Still Get a Cavity if It Has a Crown?

Posted in Crowns

Your tooth may look well sealed-up after getting a pristine new dental crown. But the fact is, it’s not invincible.

Watch Out for the Margin

You’ve just had to go through a lot of “work” and possibly even a root canal. Before that, the tooth may have had a large cavity. You’d like to think your tooth is now set for life!

Dental crowns, however, have their limits. They only cover the tooth to a point that’s just below the gum line. Where the crown edge meets the tooth is called the margin.

Your dentist makes that margin as smooth as possible. But it’s still a prime area for collecting bacteria that cause cavities. When a cavity starts at the margin, it works its way under the tooth undetected.

Oral Hygiene a Must

To avoid getting a cavity under your new crown, you must do your part.

Brush daily with a fluoride toothpaste and carefully floss around your crown (and other teeth) to remove plaque.

If you are at high-risk for tooth decay, your dentist may recommend that you extend the life of your crown by using a prescription fluoride gel.

No Crowns Last Forever

Gold crowns last a long time. Metal ones hold up to wear and tear. Porcelain crowns are strong and beautiful.

But there isn’t yet a crown that’s guaranteed to protect your tooth indefinitely.

That’s why you need to schedule routine dental check-ups. A dentist can evaluate your crown with examinations and x-rays to check for signs of weakness or decay in the tooth underneath.

So don’t put off your next dental visit! It could be just what your crown needs to avoid getting a cavity.
