Dental crowns can be fashioned from a range of different materials which include stainless steel, ceramic, acrylic, gold and metal alloys. Crowns are cemented onto existing teeth or implants, and can only be removed by your dentist.
A crown can be used for many purposes:
- Protect a weak tooth from breaking
- Restore an already damaged tooth
- Replace a large filling when there is not enough tooth remaining
- Hold a dental bridge in place
How long does a dental crown last?
With good oral hygiene, crowns can last a lifetime. A crown may come loose or fall out if the underlying tooth is damaged by gum disease or tooth decay. Crowns are made to match the color of your natural teeth.
Dental bridges, also known as fixed removable dentures, literally bridge the gap created by one or more missing teeth. A typical bridge is made up of two crowns (one on either side of the gap) and a false tooth/teeth in between. Bridges are attached to surrounding natural teeth or dental implants for support. If you have lost a tooth/teeth, bridges can restore your smile, your ability to properly speak and chew and maintain your facial structure. Bridges can also prevent your remaining teeth from shifting out of position.
How long do dental bridges last?
Depending on which type of bridge your dentist suggests, its success depends on the foundation. This is why it’s vital to keep your remaining teeth strong and healthy. On the average, dental bridges can last five to seven years. With good oral hygiene and regular professional cleaning, a fixed bridge can even last for over a decade.
