Bridges and crowns are both fixed dental devices.
Being different from removable devices like dentures which can be taken out daily and cleaned, both get permanently cemented onto the existing teeth and may be removed only by a dentist.
A bridge covers the opening between your missing teeth.
It "bridges" the gap.
After losing a tooth, the dentist might recommend that you obtain a bridge.
Additionally, a bridge may keep the other teeth from shifting out of position.
Once the bridge has been put into place, it will work similar to the original teeth.
On the hand, a crown is essentially a tooth-shaped cap which gets placed over your tooth.
The aim is to protect and strengthen the dental structure.
Majority of crowns are prepared from a tough, white substance so as to appear natural.
According to the American Academy of Cosmetic Dentistry, dental crowns are not just limited to replacing your natural tooth, but may be so designed so as to produce a better aesthetic look.
How Bridges And Crowns Are Made Prior to either a bridge or a crown being made, the tooth has got to be reduced in terms of size such that the bridge or crown is able to properly fit on top of it.
An impression is then taken to give an accurate mold for the bridge or crown.
If ceramic/porcelain is what is going to be used for your case, the dentist will decide the proper shade for the bridge or crown to go with the colour or shade of the existing teeth.
Utilizing the tooth impression, the dental lab will then create your bridge or crown as per the material specified by your dentist.
In the meantime, a temporary bridge or crown gets put in place covering your prepared tooth as the permanent one is being created.
Once it is ready and the temporary one removed, the new one gets cemented over the prepared tooth.
The Work Of Bridges If you happen to be missing a tooth or more, a bridge may be suggested.
The gaps left behind by any missing teeth will ultimately cause the remaining ones to shift into those empty spaces or to rotate leading to a bad bite.
Besides, the dental imbalance triggered by the missing teeth could cause joint disorders and gum diseases.
Bridges are generally utilized in replacing one or more teeth that are missing.
They get cemented to your natural teeth or even to implants that surround the vacant hole or gap.
Similar to crowns, one has choice of bridge substances.
Options for material or substances to be utilized include missing the location of the tooth, the cost and aesthetics.
Bridges made of ceramic or porcelain may be matched to suit your natural teeth color.
The Work Of Crowns A crown is employed to completely cover damaged tooth.
Apart from strengthening a tooth that is damaged, a crown may be utilized to enhance its shape, appearance or alignment.
Ceramic or porcelain crowns may be made to match your natural teeth shade.
Some other materials used to make bridges are gold, acrylic and metal alloys.
Metal alloys are normally stronger than the rest and are recommended for your back teeth.
Frequently used is porcelain that has been bonded into a metal shell since it is both attractive and strong.
The Journal of Oral Science Volume 12 of 2004 states that, as all ceramic or porcelain crowns offer highly aesthetic dental restorations, their reputation has grown with the rising demand by many for cosmetic dentistry.
