Crowns & Bridges

Brief history of Dental crowns and bridges

Archaeological discoveries reveal that as early as 200 AD, the Etruscans used gold and other materials to create crowns and bridges for teeth restoration. This practice was not only aimed at restoring the function of teeth but also displayed a form of wealth and status. The modern era of dental crowns began in the 1900s with the development of porcelain crowns, which offered a more natural appearance. This period also marked significant advancements in adhesion techniques, allowing crowns to better bond with teeth. Similarly, dental bridges, which replace missing teeth by anchoring to adjacent teeth or implants, have evolved concurrently. The introduction of stronger materials such as porcelain fused to metal in the mid-20th century, and more recently, the development of durable and aesthetic all-ceramic and zirconia bridges, reflect the ongoing advancements aimed at improving the longevity, appearance, and functionality of dental restorations. This historical evolution underscores a commitment to enhancing oral health and patient satisfaction through technological innovation.

Why Do You Need Dental Crowns?

A dental crown is a custom-made restoration that completely covers or "caps" a tooth, restoring it to its natural size, shape, and functionality. Crowns are recommended for teeth that have been weakened by decay, injury, or large fillings, offering protection and strength to the compromised structure. They can also be used for aesthetic improvements, such as modifying the shape or alignment of a tooth, or to cover a dental implant.  The process of placing a crown typically requires two dental visits; the first to prepare the tooth and place a temporary crown, followed by a second visit to fit and permanently affix the custom-made crown.

Dental Bridges

For patients who cannot or don't want dental implants
A dental bridge is an effective solution for replacing one or more missing teeth. Structurally, it consists of two or more crowns for the teeth on either side of the gap — known as abutment teeth — and a false tooth/teeth in between.
At one point, these false teeth, where made from gold, alloys, porcelain, or a combination of these materials. Today however they are made from porcelain.
Dental bridges are supported by natural teeth or implants and are crucial not only for restoring the aesthetics of a smile but also for maintaining the proper alignment of remaining teeth, distributing the forces in your bite correctly, and preserving the shape of your face.
The procedure for installing a dental bridge usually involves two visits to ensure a precise fit and natural appearance, mirroring the meticulous process of placing a dental crown.

Types of Crowns and Bridges


What material does Dr. Rahimi recommend for a crown or bridge?

Zirconia crowns and bridges stand out as superior materials due to their exceptional strength and durability. Manufactured from zirconium dioxide, a highly tough material, they are capable of withstanding the everyday wear and tear that dental restorations are subjected to, making them an ideal choice for both front and back teeth. Beyond their robustness, zirconia offers a significant aesthetic advantage; its translucent nature mimics the look of natural teeth more closely than metal-based alternatives, allowing for a more natural and appealing smile. Furthermore, zirconia is biocompatible, meaning it is less likely to provoke an allergic reaction in patients, enhancing the overall safety and comfort of dental restorations. Its ability to be precisely matched to the color of surrounding teeth through advanced coloration techniques ensures a seamless integration into the patient's existing dental structure. For these reasons, zirconia crowns and bridges are increasingly recognized as the best material choice for patients seeking long-lasting and aesthetically pleasing dental restorations.

Can I do a one same day zirconia crown or bridge?

For patients seeking an expedited procedure, same-day crowns offer a convenient solution, providing the restoration within a single visit. This swift approach utilizes advanced CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) technology to design and mill the crown on-site. However, it's important to note that same-day crowns are not crafted from zirconia due to the specific requirements of the material. Zirconia crowns necessitate special cutting burs for precise shaping and a hotter oven for sintering, which are processes that cannot be accommodated within the timeframe of a single visit. Instead, same-day crowns are typically made from ceramic or composite materials that can be quickly and efficiently machined using the CAD/CAM system. While these materials still offer durability and a satisfactory aesthetic result, patients prioritizing the unique benefits of zirconia may need to opt for the traditional, longer process.

What's the life span of a crown or bridge?

The longevity of a dental crown is influenced by several key factors, including the material from which it is made, the effectiveness of the dental care regimen, and the individual's lifestyle habits. While zirconia crowns are renowned for their durability, often lasting anywhere from 10 to 15 years and sometimes even longer, the actual lifespan can vary significantly from one patient to another. Regular dental check-ups, maintaining good oral hygiene, and avoiding habits such as teeth grinding, biting on hard foods, or using teeth as tools can help extend the life of a crown. Additionally, the location of the crown in the mouth plays a role, as those on molars bear more force from chewing, which could potentially shorten their lifespan. Ultimately, a combination of high-quality material, professional dental care, and conscientious personal habits are paramount to maximizing the longevity of dental crowns.

Why some older Americans on the media have such white teeth?

The trend of older individuals having remarkably white teeth can often be attributed to dental restorations rather than natural tooth enamel. Over time, natural teeth can discolor due to a variety of factors, including diet, personal habits like smoking, or simply the aging process itself, which may lead to enamel wear and a yellowish appearance. Many older adults opt for dental procedures such as crowns, veneers, or professional whitening treatments to restore or improve the appearance of their teeth. These restorations are made from materials that do not stain as easily as natural tooth enamel and can be matched to a preferred shade of white, often leading to the super white teeth observed. Additionally, advances in dental technology and aesthetic dentistry have made these options more accessible and desirable for individuals seeking to maintain a youthful appearance.

Does insurances cover these procedures?

Dental insurance policies typically cover dental crowns and bridges, recognizing them as essential procedures for restoring and maintaining oral health. Coverage levels may vary, with many plans covering a substantial portion of the cost, though this often depends on whether the crown or bridge is deemed necessary for medical reasons as opposed to purely cosmetic ones. It's important for patients to review their policies or consult with their insurance providers to understand the specifics of their coverage, including any deductibles, co-payments, or caps on coverage. Additionally, insurance companies may have stipulations regarding the types of materials used for crowns and bridges, influencing the overall out-of-pocket expenses for patients.
