Comprehensive Guide to Dental Crowns: Everything You Need to Know
A **dental crown** is a tooth-shaped cap or cover placed over a remaining natural tooth structure. Dental crowns are designed to restore the original shape, size, strength, and overall appearance of the tooth. These restorations play a crucial role in modern dentistry, offering both functional and aesthetic benefits. They protect and restore weak or broken teeth, often damaged by decay. Other common reasons for the placement of dental crowns include holding dental bridges in place, covering dental implants, following root canal therapy, and making cosmetic modifications like covering misshapen or discolored teeth.
In this comprehensive guide, we’ll explore everything you need to know about dental crowns, from the materials used and the procedure itself to the various benefits and potential risks. Whether you're considering a crown for cosmetic reasons or to restore a damaged tooth, this article will provide you with the information needed to make an informed decision.
#### 1. **What Are Dental Crowns Made Of?**
Dental crowns are made from a variety of materials, each offering unique benefits depending on the specific needs of the patient. Here’s a breakdown of the most common materials used:
- **Porcelain Crowns:** Porcelain crowns are popular for their natural appearance. They closely mimic the color and texture of natural teeth, making them an ideal choice for front teeth restorations. Porcelain is also biocompatible, meaning it’s less likely to cause allergic reactions.
- **Ceramic Crowns:** Ceramic crowns are similar to porcelain but are known for their strength and durability. These crowns are often used for back teeth due to their ability to withstand biting and chewing forces.
- **Resin Crowns:** Resin crowns are more affordable and are often used as temporary solutions. However, they are less durable and more prone to wear and tear compared to porcelain or ceramic.
- **Stainless Steel Crowns:** Stainless steel crowns are typically used for primary teeth in children. These crowns are durable and protect the tooth from further decay. Once the primary tooth falls out, the crown naturally falls out with it.
- **Metal Crowns (Gold Alloys, Base Metal Alloys):** Metal crowns are incredibly durable and can withstand significant biting and chewing forces. However, due to their metallic color, they are usually reserved for molars that are less visible.
Each material has its pros and cons, and the choice depends on various factors such as the location of the tooth, the extent of the damage, and the patient's budget.
#### 2. **The Dental Crown Procedure: Step-by-Step**
The placement of a dental crown typically requires two visits to the dentist, though some practices offer same-day crowns using advanced technology. Here’s what you can expect during the process:
**First Visit: Preparation and Temporary Crown Placement**
- **Step 1: Anesthesia Application:** The dentist will apply local anesthesia to numb both the tooth and the surrounding gum tissue. This ensures that you won’t feel any discomfort during the procedure.
- **Step 2: Tooth Reshaping:** Once the area is numb, the dentist will reshape the surface of the tooth. This involves removing a portion of the tooth's outer structure to make room for the crown. The amount of tooth reduction depends on the type of crown being used.
- **Step 3: Taking Impressions:** After reshaping the tooth, the dentist will take an impression of the remaining tooth structure. This is usually done using a putty-like material or a digital scanner. The impression is sent to a certified dental laboratory, where the permanent crown is custom-made to fit your tooth perfectly. This process typically takes about three weeks.
- **Step 4: Temporary Crown Placement:** While waiting for the permanent crown, a temporary crown is placed over the tooth for protection. Temporary crowns are usually made of acrylic and are held in place by temporary cement.
**Second Visit: Permanent Crown Placement**
- **Step 1: Anesthesia Application:** Similar to the first visit, the dentist may apply local anesthesia to numb the tooth and gum tissue.
- **Step 2: Temporary Crown Removal:** The temporary crown is carefully removed to expose the reshaped tooth.
- **Step 3: Fitting the Permanent Crown:** The dentist will check the fit and appearance of the permanent crown. This step is crucial to ensure the crown aligns correctly with your bite and looks natural.
- **Step 4: Cementation:** Once the dentist is satisfied with the fit, the permanent crown is cemented into place using a special adhesive. The dentist will make any final adjustments to ensure a comfortable bite.
#### 3. **Benefits of Dental Crowns**
Dental crowns offer numerous benefits, making them a popular choice for restoring damaged teeth. Some of the key advantages include:
- **Protection:** Crowns provide a protective barrier, preventing further damage to a weakened or decayed tooth.
- **Restoration of Function:** By restoring the tooth's shape and size, crowns help in maintaining the proper function of the tooth, allowing you to chew and speak effectively.
- **Aesthetic Improvement:** Crowns can significantly enhance the appearance of your teeth, especially when used for cosmetic purposes. They can cover discolored or misshapen teeth, giving you a brighter and more uniform smile.
- **Durability:** With proper care, dental crowns can last many years, providing a long-term solution for tooth restoration.
- **Support for Other Dental Procedures:** Crowns are often used in conjunction with other dental treatments, such as holding a dental bridge in place or covering a dental implant.
#### 4. **Potential Risks and Considerations**
While dental crowns are generally safe and effective, there are some potential risks and considerations to keep in mind:
- **Tooth Sensitivity:** After getting a crown, you may experience some sensitivity to hot or cold temperatures. This is usually temporary, but in some cases, it may persist.
- **Allergic Reactions:** Although rare, some patients may have an allergic reaction to the materials used in the crown, especially metal alloys.
- **Crown Loosening or Falling Off:** Over time, the cement holding the crown in place can weaken, causing the crown to become loose or even fall off. Regular dental check-ups can help prevent this.
- **Decay Under the Crown:** If proper oral hygiene is not maintained, decay can develop under the crown, leading to further dental issues.
- **Gum Irritation:** Some patients may experience gum irritation around the crown. This can often be managed with proper dental hygiene and regular check-ups.
#### 5. **Aftercare Tips for Dental Crowns**
Proper care is essential to ensure the longevity of your dental crown. Here are some tips to help you maintain your crown:
- **Practice Good Oral Hygiene:** Brush your teeth at least twice a day and floss daily to prevent plaque build-up around the crown.
- **Avoid Hard Foods:** While crowns are durable, chewing on hard foods like ice or hard candy can damage the crown.
- **Use a Mouthguard:** If you grind your teeth at night, consider using a mouthguard to protect your crown from excessive wear.
- **Visit Your Dentist Regularly:** Regular dental check-ups are crucial to monitor the condition of your crown and address any potential issues early on.
#### 6. **When to Consider a Dental Crown**
There are several situations where a dental crown may be the best option:
- **Severe Tooth Decay:** If a tooth is extensively decayed and cannot be restored with a filling, a crown may be necessary to save the tooth.
- **Cracked or Broken Teeth:** Crowns can provide the necessary strength and protection for cracked or broken teeth, preventing further damage.
- **Root Canal Treatment:** After a root canal, the tooth can become brittle and more susceptible to fractures. A crown helps protect the tooth and restore its function.
- **Cosmetic Enhancements:** If you have discolored, misshapen, or worn teeth, crowns can significantly improve your smile's appearance.
#### 7. **Cost of Dental Crowns**
The cost of dental crowns varies depending on the material used, the complexity of the procedure, and your location. On average, the price can range from $800 to $2,500 per crown. Insurance may cover part of the cost, especially if the crown is necessary for medical reasons rather than purely cosmetic purposes.
#### 8. **Frequently Asked Questions (FAQs) About Dental Crowns**
**Q: How long do dental crowns last?**
A: With proper care, dental crowns can last anywhere from 5 to 15 years, and sometimes even longer.
**Q: Are dental crowns noticeable?**
A: Modern dental crowns are designed to look natural and blend seamlessly with your surrounding teeth.
**Q: Is the procedure painful?**
A: The procedure itself is not painful as it is done under local anesthesia. However, some patients may experience mild discomfort after the procedure, which can usually be managed with over-the-counter pain relievers.
**Q: Can I whiten a dental crown?**
A: No, dental crowns cannot be whitened. If you're considering teeth whitening, it's best to do it before getting a crown so that the crown can be matched to the new shade of your teeth.
**Q: What happens if my crown falls off?**
A: If your crown falls off, contact your dentist immediately. In the meantime, try to keep the area clean and avoid chewing on that side of your mouth.
