I received two dental crowns in 2012. One of the top molar crowns has a cavity beneath it. I had been complaining to my dentist about it on and off or about two years. After my checkup two weeks ago, she said the x-ray shows a cavity. I guess that I shouldn’t have waited to see another dentist about my tooth sensitivity and dull pain. But I’m nervous about dental appointments. How can a cavity develop beneath a crown? Karissa from Macon, GA
You’ve had your crowns for eight years. Usually, a dentist won’t find decay beneath your crown within that period. But there are two reasons that decay might develop.
Two Reasons for Decay Beneath a Dental Crown
Your dental history – If you have a history of cavities, it might not be surprising that there is decay beneath a dental crown.
Your dentist’s placement of the crown – A dentist must ensure that the margin—where your crown and tooth meet—is smooth and without gaps. Any roughness or gaps will attract plaque, bacteria, and decay. If decay isn’t noticed and treated during your dental exams and cleaning, the decay will progress and result in the symptoms you’re feeling—sensitivity and pain.
After your completed complaints about the crown, your dentist should have completed a thorough examination and x-rays without delay. Don’t let your dentist’s delay discourage you. Get prompt care.
How Long Do Dental Crowns Last?
Although insurance companies won’t pay for a replacement crown that is fewer than five years old, most dentists expect a crown to last longer. And conscientious dentists are embarrassed if decay is found beneath a crown they placed.
We recommend that you find an advanced cosmetic dentist in your area to examine your tooth and crown. The extent of the decay will determine your treatment option. But you should seek prompt care to receive the least invasive treatment options possible.
Take Advantage of Sedation Dentistry
If you’re nervous about dental appointments, you may have received sedation in the past. Don’t be embarrassed about your anxiety. Take advantage of sedation options and let an advanced cosmetic dentist help you preserve your oral health.
