Dental crowns are an essential restorative dental solution designed to protect and enhance teeth. They serve various purposes, from strengthening damaged teeth to improving cosmetic appeal. Choosing the right type of crown depends on multiple factors, including the material, cost, and your specific dental needs. When a tooth is too weak or damaged for a simple filling, this type of restoration is often recommended to restore strength and function. Let’s explore the types of dental crowns, their benefits, and how they can enhance oral health. If only part of the tooth is damaged, full coverage may be more than you need, so it helps to compare partial crown vs full crown before settling on a material.
What Are Dental Crowns?
Dental crowns, also known as caps, are tooth-shaped coverings placed over teeth to restore their shape, size, and strength. They are commonly used to:
- Protect weakened teeth.
- Restore broken or severely worn teeth.
- Cover dental implants.
- Improve the appearance of discolored or misshapen teeth.
