Losing a significant portion of a tooth can be a disconcerting experience, often requiring a crown to restore its structure and function. However, the process isn't immediate. You'll likely receive a temporary crown before getting a permanent one. Understanding the key differences between temporary and permanent crowns is crucial for managing expectations and ensuring a smooth dental procedure. This comprehensive guide will illuminate the distinctions, addressing common questions and concerns.
What is a Temporary Crown?
A temporary crown, also known as a provisional crown, is a temporary restoration placed on a prepared tooth while the permanent crown is being fabricated in a dental laboratory. It's typically made from acrylic or metal, materials that are less durable and aesthetically pleasing than permanent crown materials but suffice for the interim period. Its primary purpose is to protect the prepared tooth, maintain its shape, and prevent further damage or sensitivity until the permanent crown is ready.
What is a Permanent Crown?
A permanent crown is a custom-made restoration designed to precisely fit over a prepared tooth. It's crafted from stronger, more aesthetically pleasing materials like porcelain, ceramic, metal alloys (gold, or base metal alloys), or a combination thereof. Permanent crowns are significantly more durable and resilient than their temporary counterparts, designed to last for many years with proper oral hygiene and regular dental check-ups.
What are the Key Differences Between Temporary and Permanent Crowns?
The most significant differences between temporary and permanent crowns lie in their material, durability, fit, and longevity:
| Feature | Temporary Crown | Permanent Crown |
|---|---|---|
| Material | Acrylic, metal, or a combination thereof | Porcelain, ceramic, metal alloys, or composites |
| Durability | Low; susceptible to chipping and breakage | High; resistant to wear and tear |
| Fit | Generally less precise; may feel loose or bulky | Precisely fitted; feels natural and comfortable |
| Longevity | Few weeks to a few months | Many years with proper care |
| Appearance | Less aesthetically pleasing; may appear unnatural | Highly aesthetically pleasing; matches natural teeth |
| Cost | Significantly less expensive | More expensive |
How Long Does a Temporary Crown Last?
A temporary crown typically lasts for two to four weeks, although it can sometimes last longer depending on the individual case and the care taken. It's vital to treat your temporary crown with care during this period. Avoid chewing hard foods or sticky substances that could dislodge or damage it.
How Long Does a Permanent Crown Last?
With proper care, a permanent crown can last for 10 to 15 years or even longer. Regular dental checkups and diligent oral hygiene practices are key to extending its lifespan.
Can a Temporary Crown Fall Out?
Yes, a temporary crown can fall out. This is more likely if it's not properly cemented or if you engage in activities that exert excessive pressure on your teeth. If your temporary crown falls out, contact your dentist immediately.
What Happens if My Temporary Crown Falls Out?
If your temporary crown falls out, contact your dentist as soon as possible. They may be able to re-cement it or provide a temporary replacement until your permanent crown is ready. Leaving the prepared tooth exposed could lead to sensitivity, further damage, or infection.
What Should I Avoid With a Temporary Crown?
Avoid chewing hard, sticky, or chewy foods to prevent damage or dislodgement of your temporary crown. Also, be cautious when flossing and brushing around the temporary crown to avoid dislodging it.
Are Permanent Crowns Worth the Extra Cost?
While permanent crowns are more expensive upfront, their superior durability, longevity, and aesthetics typically make them a worthwhile investment. They offer long-term protection and a natural-looking smile, minimizing the need for frequent replacements and potential complications.
