What to Do if Your Dental Crown Fails

Many of us have dental crowns as they are one of the more common dental restorations done. Since their job is to protect your remaining tooth, they are made to last.

But while dental crowns are incredibly durable, they are not indestructible. Experiencing a failed crown is more common than you might think. It can be startling when your crown cracks, loosens, or falls off, but don’t panic! Knowing what to do can keep you calm and help you get your smile whole again ASAP.

Why Do Dental Crowns Fail?

A dental crown is a sturdy and durable cover that protects a damaged tooth underneath. It can fail for a variety of reasons, ranging from simple wear and tear to underlying health issues. Being aware of the common causes can help you protect your investment and recognize warning signs early.

Decay Underneath the Crown

While a crown may be used to cover a tooth after treatment for significant decay, it doesn’t guarantee that decay won’t occur again. The crown itself cannot decay, but the natural tooth structure underneath it can. If bacteria and plaque get under the edges of the crown, a new cavity can form, weakening the tooth and compromising the crown’s foundation.

Cement Failure

The dental cement used to bond the crown to your tooth is specifically made for this purpose, and it is designed to bond your crown to your tooth for a long time. However, it is still possible for this cement to degrade. This can cause the crown to become loose and eventually fall off.

Bite and Grinding Issues

Clenching or grinding your teeth puts a great deal of pressure on your crowns. This constant force can cause the porcelain to chip, crack, or fracture. An improper bite can also create uneven pressure points, leading to failure.

Trauma or Injury

A direct blow to the mouth from an accident or biting down on something extremely hard (like ice or a nut shell) can easily chip or dislodge a crown.

Steps to Take if Your Crown Fails

If you notice a loose, broken, or missing crown, it should be managed as soon as possible. Here are the essential steps to take as soon as you notice a problem.

Call Your Dentist Immediately

Contact your dentist’s office right away and explain the situation. We will want to schedule an appointment quickly. The underlying tooth may be exposed and vulnerable to damage, sensitivity, and decay. Delaying treatment can lead to more complex and costly problems, such as needing a root canal or even an extraction.

Safely Store the Crown

If the crown has fallen out completely, carefully remove it from your mouth to avoid swallowing or inhaling it. Rinse it with water and store it in a small, secure container. It’s important to bring the crown with you to your dental appointment, as it may be possible to re-cement it. Do not attempt to reattach the crown yourself with over-the-counter glues, as this can damage the crown and your tooth.

Don’t Use Your Tooth

If your crown is damaged, avoid further issues by not chewing on the side of your mouth where the crown is located. In addition, if your crown came off, the exposed tooth tissue can be very sensitive to temperature and pressure. Steer clear of very hot, cold, or sugary foods and drinks.

Consider CEREC

If you require a replacement crown, ask about CEREC. Traditional crowns require multiple visits to place a temporary crown while you wait for your permanent crown to be fabricated. With CEREC, your new permanent crown is created while you wait. This new technology is not only more convenient for you, but you can know your compromised tooth is protected with a durable, permanent crown in just one visit.

How to Prevent Future Crown Issues

Once your crown is repaired or replaced, you’ll want to do everything you can to ensure it lasts. Prevention is the best medicine for protecting your dental work.

Oral Hygiene: Brush twice a day, paying special attention to the area where the crown meets the gum line, as this is where plaque tends to accumulate. And, don’t skip flossing around your crown.
Wear a Nightguard: If you clench or grind your teeth at night, a custom-fitted nightguard is the single best way to protect your crowns (and your natural teeth).
Avoid Chewing Hard Things: Don’t chew on ice, pens, or fingernails. Be cautious with extremely hard or sticky foods that can put your crown at risk.
Regular Dental Check-ups: Visit your dentist for regular cleanings and exams every six months. These appointments allow us to monitor your crowns, check for any early signs of failure, and professionally clean areas you might miss.
