A dental crown is a type of cap that is placed over a tooth. Think of it like a protective helmet for a tooth. It’s designed to restore its shape, size, strength, and appearance. Crowns can be made from various materials, including metal, porcelain, resin, or a combination of these.
Why Would You Need a Dental Crown?
There are several reasons why a dentist might recommend a dental crown:
- To Protect a Weak Tooth: If a tooth is cracked or weakened (perhaps due to decay), a crown can help hold it together and prevent further damage.
- To Restore a Broken Tooth: If a tooth is fractured, a crown can provide a durable surface to restore its function.
- To Cover a Tooth After a Root Canal: After a root canal treatment, the tooth may be more fragile. A crown helps protect it and allows it to function normally.
- To Improve Appearance: Crowns can also be used for cosmetic purposes, such as covering discolored or misshapen teeth.
- To Support a Dental Bridge: If you have missing teeth, crowns can hold a bridge in place.
Types of Dental Crowns
Crowns can be made from various materials, each with its advantages:
- Metal Crowns: These are very strong and durable, making them great for back teeth where chewing pressure is highest. However, they’re not the most aesthetic choice since they don’t match the natural color of teeth.
- Porcelain-Fused-to-Metal Crowns: These offer a good balance between strength and appearance. They have a metal base for durability but are covered with porcelain to match the natural color of teeth.
- All-Porcelain Crowns: These provide the best natural look and are often used for front teeth. However, they can be less durable than metal options.
- Resin Crowns: These are less expensive but not as durable as other types. They can be a good temporary solution.
How is a Dental Crown Made?
The process of getting a crown usually involves multiple steps:
- Initial Consultation: The dentist examines your tooth and takes X-rays to assess its health. They will discuss the options available and recommend the best type of crown for your situation.
- Tooth Preparation: If a crown is deemed necessary, the dentist will prepare the tooth. This involves removing any decay and shaping the tooth so that the crown can fit snugly over it. Depending on the tooth’s condition, this may involve filing down the tooth or building it up if too much has been lost.
- Taking Impressions: After preparing the tooth, the dentist takes impressions of your mouth. This can be done using traditional putty or digital scans. These impressions help create a custom crown that fits perfectly.
- Temporary Crown: While your permanent crown is being made (which can take a couple of weeks), a temporary crown will be placed to protect your tooth. It’s not as durable as the permanent one but serves its purpose.
- Crown Fabrication: The impressions are sent to a dental lab, where skilled technicians create your crown. This process may take anywhere from a few days to a couple of weeks, depending on the lab’s workload and the type of crown being made.
- Fitting the Crown: Once your crown is ready, you’ll return to the dentist’s office. The dentist will remove the temporary crown and check the fit and color of the permanent crown. Adjustments can be made to ensure comfort and aesthetics.
- Cementing the Crown: After everything is perfect, the dentist will permanently cement the crown onto your tooth. You may need to wait a short time for the cement to set before resuming normal activities.
Caring for Your Crown
Once you have a crown, taking care of it is essential to ensure it lasts:
- Good Oral Hygiene: Brush and floss regularly. Treat your crown as you would a natural tooth.
- Avoid Hard Foods: If you have a porcelain crown, avoid biting down on hard foods, as they can chip.
- Regular Dental Visits: Keep up with routine check-ups so your dentist can monitor the health of your crown and surrounding teeth.
- Protecting Against Grinding: If you grind your teeth, talk to your dentist about a night guard to protect your crown.
Potential Issues with Dental Crowns
While crowns are generally safe and effective, some issues can arise:
- Sensitivity: After getting a crown, some people experience tooth sensitivity. This is usually temporary but should be discussed with your dentist if it persists.
- Crown Damage: Crowns can chip or crack, especially if you eat hard foods or grind your teeth.
- Decay Underneath: If proper oral hygiene isn’t maintained, decay can still occur beneath the crown, leading to further issues.
- Loosening: Over time, crowns can become loose. If this happens, you should see your dentist promptly.
