Dental Crowns and Bridges
Simply stated, a dental crown is a tooth cap placed to cover the tooth to restore its shape, its size and its strength. A bridge is a combination of crowns.
A dental crown may be advised to:
- Protect a weak tooth (for instance, from decay) from breaking especially after an RCT
- Restore an already broken tooth or a tooth that has been severely worn down
- Cover and support a tooth with a large filling when there isn’t a lot of tooth left
- Hold a dental bridge in place
- Cover misshaped or severely discolored teeth
- Over a dental implant
Dental bridges are meant to replace missing teeth by “bridging” the gap between two remaining teeth. This involves creation of a pontic, or false tooths with a dental crown on either side. The crowns are fitted over the remaining teeth to hold the false tooth in place.
When there are only teeth on one side of the gap, cantilever bridges may be given. cantilever bridges consist of two side-by-side crowns and only one is connected to the pontic.
A fixed bridge helps to
- Replace missing tooth/teeth.
- Helps balance a normal bite.
- Helps prevent undesirable stress on the dental ridge.
- Prevents over-eruption of the opposing teeth.
- Prevents drift and tilt of adjacent teeth.
- Prevents tooth decay in adjacent drifted teeth.
- Retards onset of gum diseases
To design a bridge, the dentist must reshape the teeth to make room for the crowns. The dentist then makes a mold of the teeth. This mold is then sent off to a laboratory, where the actual crowns and bridge are made.
These crowns and bridges require a bit of extra care in terms of oral hygiene. With such care, bridges can last up to several years. However, improper or infrequent brushing and flossing, irregular dental visits, and excessive sugar and starch intake can all bring untimely damage to the bridge.
All Metals and Gold Crowns | Dental Crowns and Bridges Dentist in Hyderabad
Metals – These could include gold alloy and other base metal alloys. Metal dental crowns are by far the toughest. They can withstand daily wear and tear and they rarely break or chip.
A gold crown has some very distinct characteristics that make it a good choice
1.Gold Fits better: A well-cast gold crown fits considerably better then other materials. Because it fits better, it lasts longer! The bacteria we all have in our mouths have less access to the micro-margins.
2.Gold Is Strong And Flexible: Gold expands and contracts at the same rate as your natural tooth. This protects the gold crown from chipping, cracking or breaking; which can be a problem with other less versatile materials.
3.Gold Is Safe And Comfortable: Gold doesn’t just look good–it feels good–because gold is remarkably compatible with the inside of your mouth. With many other metals, the likelihood of sensitivity or an allergic reaction is a significant risk for the patient. But not with gold.
