A dental bridge is used to replace gaps left by missing teeth; the bridge is composed of multiple dental crowns in a row and is permanently cemented on to the tooth dentin below it. The dental bridge is used to replace missing teeth and restore chewing.
Dental Bridges can be made out of the following materials
Porcelain or Ceramic Dental Bridge
- Works well if you have a metal allergy
- Match your natural tooth shade
- Have a natural tooth like appearance
- Can only bridge so many teeth long. This is because of its physical properties; it does not contain metal so it is not malleable and does not bend easily.
Gold Dental Bridge
- Less irritating to gums then any of the other materials
- Minimal wear to opposing teeth
- Known to inhibit future decay because of the antimicrobial properties of gold
- Can be used to bridge a large gap of teeth, this is because it contains metal which is malleable and allows the material to bend
- Usually used in the back molars because it is gold in color
Porcelain Fused to Metal Dental Bridge
- Can have a natural tooth like appearance but the metal may start appearing around the edges of the crown once your gums shrink back. This will leave a dark edge around the crown that may look like decay.
- Can be used to bridge a large gap of teeth, this is because it contains metal which is malleable and allows the material to bend.
- May chip due to differences in thermal expansion; porcelain and metal expand and contract at different rates when there is a change in temperature. For example, when you drink a cold soda and have hot soup.
- May chip due with everyday use.
- Can irritate your gums if you have a metal allergy.
