3. Poor Oral Hygiene
It’s important to remember that most dental crowns don’t fail on their own. Instead, it’s the tooth under them that fails. One thing that contributes to tooth failure is poor oral hygiene.
Typically, your dental crown will cover the entire surface portion of a tooth. The gums will close up around the crown itself so there’s very little risk that your tooth will develop cavities. However, it’s still possible to experience a cavity under a crown if you take poor care of your teeth or if your dental crown isn’t fitted properly.
Poor oral hygiene and other factors can contribute to receding gums around a dental crown, which can expose the vulnerable tooth underneath. This may even include the tooth root, which is very susceptible to tooth decay.
If you notice a black gum line around the crown, extra sensitivity, bleeding with brushing or flossing, pain or toothaches, or brown or grey spots on tooth material around the crown, you might have a cavity or gum disease. Although gum inflammation after crown placement is normal, if it persists or happens months or years after placement, it’s likely gum disease.
Always brush twice a day and floss every day (yes, even on weekends). Floss carefully around your crowns to make sure you’re cleaning all the plaque out from around it.
To ensure you don’t have a cavity on your tooth under your crown, we recommend not skipping your regular dental cleanings. We will take x-rays once a year to look for signs of decay that we can’t see with our naked eye.
