Do dental crowns need to be replaced?


If you are a patient who is going to have dental crowns or if you have had dental crowns for quite some time now, you are probably wondering about this.

The answer actually depends on a variety of factors. Appearance is not the only reason to get a new crown.

Crowns are generally provided as a restorative option for when teeth that have been weakened by decay or fracture need protection. When decay is advanced that dental filling won’t work anymore (this is when there’s not enough tooth left to fill), crowns are the best choice.

Crowns, or caps as they are also called, also help restore discoloured, broken, or misshapen teeth that need restoration. Other procedures such as tooth canaled teeth, dental implants, and the teeth that act as anchors at both ends of a bridge would also need crowns.

There are cases when crowns need to be replaced, at times even more than once.

The life of dental crowns depends on factors like the wearer’s oral health condition, as well as his or her eating habits, and of course, the material used for the crown itself.

Crowns can be replaced for cosmetic reasons or to preserve the health of the tooth if they get worn or if gum tissue recedes. Typically, porcelain and porcelain-fused-to-metal crowns last anywhere between five to 15 years. Metal crowns usually last for 20 years or beyond. Gold and zirconia crowns can last a lifetime.

If your upper and lower teeth do not fit together perfectly, there may be excessive wear on the occlusal surfaces caused by chewing. This can be worse if you grind your teeth at night. Bruxism can put pressure o crowns. So those who have malocclusion (teeth not fitting properly) or bruxism may experience early crown wear and require replacement. There may also be other treatments recommended to improve occlusion through modification and perhaps teeth realignment.

If you have a problem with your gums and the gum tissue surrounding the base of the crown recedes, the root of the tooth can also get exposed to plaque. This may lead to infection and decay inside the crown. When this gets extremely painful, it may require emergency tooth extraction. Having root canal therapy or having a dental crown doesn’t exempt you from tooth decay that can damage the remaining part of the tooth supporting the crown.
