In case of periodontal disease or injury, a dentist can employ different therapies to turn back a tooth to its natural state. Crown and bridges is one of them and are preferred overdentures. Dentures through a useful method to treat a dental problem have its limitations. They require regular upkeep and cleaning for their proper functioning. And have many hygiene-related issues with them. Offering the convenience of use without much cleaning issues they are becoming more popular than dentures.
Crown and bridges are fixed prosthetic tools implanted in place of missing teeth or dental cavity. Unlike dentures, they are fixed and are placed over existing teeth or implants. They can only be removed by a dentist. A dentist suggest them to a dental patient in case he found them suitable for a replacement in following situations:-
- In place of a large filling when enough tooth is not left out due to regular filling.
- Safeguard a weaker tooth from completely fractured or damaged.
- Reconstruct a fractured tooth.
- Link up a bridge between two damaged teeth.
- In order to cover the surface of a dental implant.
- To offer protection to a discolored or poorly shaped tooth.
- Offering a cover to undergone root canal treatment.
Crown and bridges though used as a single term but are two different things and are implemented over a tooth in a different manner.
An overview of a Crown
It is a cap in the shape of a tooth placed over the tooth to restore its shape, size, and strength. A dental crown is extremely useful in restoring back the beauty of a damaged tooth. They are fixed upon a tooth above its entire surface till the gum line so covering damaged teeth or gaps.
Different Types of Dental Crowns
On the basis of material made dental crowns are of following types:-
Stainless Steel Crown:
Also defined as prefabricated crowns they’re fixed over a permanent tooth for a short period of time. It is used for providing protection to the tooth or filling. It is very useful in a situation where a patient wishes to avoid frequent visits to a dentist. It saves a tooth from further tooth decay.
Consisted of alloys, it has a very high percentage of gold or platinum. There is also variant made up of cobalt-chromium or nickel-chromium alloys. The strength of the used metals made the crown more stronger to sustain excessive biting and chewing in comparison to other types of crowns.
These types of crowns are made to match with the color of an adjoining tooth to offer them a natural look. But porcelain-metal has more weight in comparison to nearby teeth. Moreover, they are tend to break easily and the metal lining in it gets visible through as a dark line.
On the basis of usability crowns are further divided into temporary as well as permanent. For the short time fixation, unless permanent crowns are made by a lab, the temporary crowns are made in a dentist’s office. They are made from acrylic-based material or stainless steel.
Functioning of a Crown
Crown completely covers a damaged tooth and at times is used in enhancing a tooth appearance. It is also placed over on the top of an implant to tooth-like shape and structure for function.
Functioning of a Bridge
It is suggested by a dentist if one or more teeth are missed out. It works as structure preventing nearby teeth from rotating and shifting into the empty spaces resulting in a bad bite. If not treated in time the left out space can give birth to a gum disease known as temporomandibular joint (TMJ) disorder. The natural teeth or implants surrounding the empty space are known to be abutments works as anchors for the bridge. Pontic, a replacement tooth is thus gets fixed with crown to cover the abutments. Like a crown, bridges are also made up of different materials like porcelain, gold, platinum, and others.
Sustainability Crown and Bridges
Usually, crown and bridge last for a patient’s lifetime. Occasionally, they come loose or fallout. To ensure the long life of a crown or bridge it is necessary for a patient to practice good oral hygiene. Crowns and bridges can lose their grip in case the teeth holding them are damaged due to dental disease. Brushing the teeth with the help of fluoride toothpaste twice a day keeps crown and bridges healthy. A patient should avoid chewing hard foods, ice and other hard objects to keep crown and bridges healthier for a longer time.
Several Benefits of Bridges & Crowns
As clear crown and bridges are fixed dental restorations used for replacing missed natural teeth. They are considered far better in comparison to fillings and dentures. Some of the benefits offered by crown and bridges include:-
- Security to a tooth structure: They are the best suggestion and treatment offered by a dentist to partially damaged teeth. They are not only useful in infected teeth treatment but also strengthen teeth weakened by a root canal treatment.

The crowns made up of ceramic offers a very strong and good looking replacement for a damaged tooth. With matching with nearby teeth it can bring back a smile on a patient’s face.
- Sustainability: Among the different types of dental restoration, on average they have the highest life span. Most of the cases they sustain more than fifteen years due to their fabrication from high quality and stronger materials.
- Restoring back teeth functionality: Another important function of crown and bridge is restoring dental functionality to normalcy. It helps a dental patient to chew and eat efficiently and in an effective manner. The restoration of bridges further improves a patient’s clarity of speech otherwise lost in the absence of a natural tooth.
- Equal distribution dental force: With an equal and proper distribution chewing force among supporting teeth makes chewing quite easier.
Overall, crown and bridges are the easiest way to restore back the appearance as well as the functionality of a damaged or missed tooth.
