Dental Crowns and Bridges: Restoring Your Smile
Dental crowns and bridges are fundamental procedures in restorative dentistry, aimed at restoring teeth to their full chewing function and aesthetic appearance. Here, we'll delve into what each entails and how they differ.
What is a Dental Crown?
A crown, often called a cap, is a dental restoration that fully covers a tooth. It replaces the tooth's outer enamel layer with a new material, maintaining the tooth's natural size, shape, and function. Crowns are designed to feel and function like a regular tooth and can be made to closely resemble natural teeth.
Materials Used for Crowns
-
Plastic: Used for temporary crowns; inexpensive but short-lived.
-
Full Metal: Ideal for back teeth, durable, but visually less appealing and expensive.
-
Porcelain Fused to Metal: Suitable for any tooth, offering a natural look but may show a dark line at the gum.
-
All Porcelain: Best for front teeth, most natural appearance but more fragile, especially for teeth grinders.
-
Zirconia: A versatile option for any tooth, strong, with a natural appearance but can be abrasive to opposing teeth and lacks extensive long-term studies.
Why Do Teeth Need Crowns?
Crowns are necessary when a tooth:
-
Has large decay or extensive damage.
-
Contains large fillings weakening the tooth structure.
-
Has cracks that need protection.
-
Undergoes root canal treatment, which makes teeth brittle and prone to cracking.
What is a Dental Bridge?
-
Benefits of a Bridge
- Quick replacement of 1-2 missing teeth.
- Typically covered by dental insurance.
- No surgery required.
​
-
Disadvantages of a Bridge
- Requires more effort to clean as it's harder to floss under the bridge.
- May involve removal of healthy tooth structure on adjacent teeth.
​
-
Alternatives to Bridges
-Removable Partial Dentures: These are not fixed and rest on adjacent teeth.
-Dental Implants: A more expensive option that offers a natural result, anchored in the jawbone, independent of adjacent teeth.

Maintaining Crowns and Bridges
-Maintaining dental crowns and bridges involves regular dental check-ups, good oral hygiene practices, and being mindful of the foods you eat to avoid damaging these restorations.
Both crowns and bridges play a crucial role in dental health, offering functional and aesthetic solutions to various dental issues. If you're considering either option, discuss with your dentist to understand which is best suited for your dental needs.
