My gold crown has a hole in it. Now what? (Photo)

Sometimes crowns can be repaired but if that's not possible I would advise replacing the crown with a new crown. As there is a hole, there is an increased chance of bacteria entering which can cause decay to your tooth and lead to more problems down the line.

Hello. When the crown is produced higer than normal, sometimes dentists make minor adjustments on occlusal surfaces. But if the crown is thin due to production or insufficient space between opposing tooth, that occlusal adjustments may cause such holes. In that circumstance, the crown should be renewed and sometimes additionally interocclusal space should be increased on that area. Because the cement which was used in fixing the crown will resorb by time.Such a situation may cause recurring decementation of crown or decay of the tooth underneath

Gold crowns are very soft materials compared to metal-based crowns. It is a common problem with gold crowns. If you have bruxism it will happen sooner. It won't be a problem if dentist recemented. However, you have to be sure about your dental care.
