Dental crowns are used to replace teeth with a significant portion of the structure depleted, typically due to decay or trauma. A crown is the preferred restorative treatment because it brings stability and strength while reconstructing the natural aesthetic.
In the initial stages of the tooth being fitted for a crown, the dentist will fit a temporary crown made from composite or acrylic. This works well for short-term use, with the material looking like the tooth, but not having the strength or longevity of a permanent crown.
How long do the various types of crowns last?
Ceramic and porcelain-fused-to-metal crowns
Ceramic and porcelain-fused-to-metal is a popular choice for its resistance. The metal interior structure provides stability, whilst the porcelain or ceramic is veneered to the surface to replicate the aesthetic of the natural teeth.
If this type of dental crown is properly cared for, it can last up to 15 years.
Porcelain and ceramic crowns
Porcelain and ceramic crowns are very similar and, therefore, are often grouped for their shared characteristics of a natural aesthetic.
These crowns are often preferred for the front teeth, which also contributes towards their longevity. With proper care and maintenance, these crowns can last anywhere between 5 and 15 years.
Gold crowns
Gold crowns are one of the most resistant crown materials; their strength, compounded with undesirable aesthetics, makes them a suitable choice for the back teeth. This type of crown can last longer than most crowns, with a wearing expectancy of around 15 – 20 years.
Zirconia crowns
Zirconia is biocompatible, combined with its durability makes it a great choice to reconstruct a tooth. With proper maintenance, this type of crown can withstand anywhere from 10 – 20 years.
Telescopic crowns
A telescopic crown is comprised of 2 fixtures to provide strength and increase the lifespan of the dental prosthetic. With routine care and a healthy lifestyle, wearers can expect this type of crown to last between 5 -15 years.
Maintenance tips for your dental crowns’ longevity
The best approach to maintaining your oral health is to ensure you routinely brush and floss your teeth, including the tooth with a crown. Start your routine by flossing, which ensures no remnants of food are lodged between the teeth. Then, proceed to brush the teeth for approximately two minutes.
With a crowned tooth, it’s best to avoid chewing on anything hard, which includes hard-boiled sweets, pens or our nails. Equally, avoiding using the teeth as a tool is essential to preserving a crown, avoiding opening packets and pulling tabs with the teeth.
Adjusting the diet to reduce the amount of acidic and sugary foods you consume will help to reduce the production and volume of bacteria in the mouth. Making sure not to chew on very hard and sticky food products will also protect the crown from any potential damage.
