Reasons Your Dental Crown Fell Off

It is also likely that your tooth doesn’t have adequate structure or is too short to support the dental crown properly. Crowns require enough tooth structure to stay in place. On short or worn teeth, enamel may not be enough to provide durable consistency.

2. The Deterioration of the Dental Cement

Dental cement used for holding the crown is durable and strong; however, it does not remain forever. Even with a great precaution, your teeth are likely to worsen with time; thus, your crown fell out or loosened.

3. Teeth Grinding or Clenching, Causing the Crown to Loosen

This is a major cause of premature failure of the crown, especially in the posterior teeth. If you gnash your teeth while sleeping, you will put lots of pressure on the back premolars and molars. This may loosen the cement holding your crown in position or cause your crown to break with time. In case you clench your teeth and have a crown on one of your back teeth, it is essential to put on a night guard at night to protect your oral health.

4. Recurrence of Tooth Decay

In case you do not floss or brush properly, cavities may develop under the dental crown. This does not commonly occur, but it is likely to happen. This can also happen if your doctor didn’t prepare your teeth properly before placing the dental crown. Root canal failure may also contribute to the crown fell out.

What Are My Treatment Options?

Some study suggests that it is possible to utilize an existing dental crown even though the tooth is broken beneath, although some work may be necessary before it gets reinstalled. But if the tooth gets broken underneath, you might require a new crown to make sure you have a perfect fit.

In case you require a fresh crown and the tooth gets damaged, the dentist will have to prepare the tooth, which might mean filing your tooth or putting some filling stuff to build it. The dentist then installs a temporary crown to create time for the creation of a new crown.

Other dentists also provide same-day crowns that are made from a very sturdy ceramic material such as CEREC. You may abandon your temporary dental crown in this case.
