Dental crowns are among the most effective ways to restore and enhance damaged or weakened teeth. Whether due to decay, trauma, or cosmetic concerns, crowns offer a versatile solution, providing strength, protection, and an improved appearance to treated teeth. In this detailed guide, we’ll cover all aspects of dental crowns, helping you make an informed decision about your dental health.
What is a Dental Crown?
A dental crown, sometimes called a “cap,” is a custom-fitted covering that encases the entire visible part of a tooth. Crowns are typically used to restore a tooth’s shape, size, and strength, as well as to improve its overall appearance. Dental crowns serve a variety of purposes, from protecting weak teeth to supporting large fillings and covering discolored or misshapen teeth.
Types of Dental Crowns
- Porcelain Crowns: Porcelain crowns are highly favored for their natural appearance, as they closely resemble the color and translucency of real teeth. These crowns are most often used for front teeth, where aesthetics are important.
- Metal Crowns: Made from metal alloys that may include gold or platinum, these crowns are exceptionally strong and durable. Metal crowns are ideal for molars because they can withstand chewing forces without chipping or breaking.
- Porcelain-Fused-to-Metal (PFM) Crowns: Combining the strength of metal with the aesthetics of porcelain, PFM crowns are durable and natural-looking. However, over time, the metal base can show as a dark line near the gumline, especially if gums recede.
- Zirconia Crowns: Zirconia crowns offer the best of both worlds — strength and aesthetics. They are biocompatible, metal-free, and durable, making them ideal for front and back teeth.
- Temporary Crowns: Typically made from acrylic or resin, temporary crowns are placed on teeth while waiting for a permanent crown to be fabricated. Although not as durable, temporary crowns provide essential protection for a short time.
- Same-Day Crowns (CEREC Crowns): With the aid of CAD/CAM technology, same-day crowns are designed, created, and fitted in a single visit. Although convenient, same-day crowns might not be suitable for complex cases.
The Dental Crown Procedure
The dental crown procedure usually involves two appointments:
- Preparation: The dentist removes any decay, reshapes the tooth, and takes impressions to ensure the crown fits snugly. If the patient is getting a traditional crown, they’ll receive a temporary one while the permanent crown is being created in a dental lab.
- Fitting: During the second visit, the dentist removes the temporary crown and fits the permanent one, checking the fit and bite. After adjustments, the crown is cemented into place.
Dental Crowns for Front Teeth
Crowns for front teeth require particular attention to aesthetics. Porcelain and zirconia crowns are typically chosen for front teeth, as they mimic natural tooth color and translucency. These crowns seamlessly blend in with your smile and are custom-tinted to match your existing teeth.
Temporary Dental Crowns
Temporary crowns act as placeholders while waiting for a permanent crown. Though functional, they are less durable and require extra care to avoid dislodgment. Temporary crowns are generally made of resin or acrylic and are essential for protecting the tooth until the permanent crown is ready.
Porcelain Dental Crowns
Porcelain crowns are an excellent option for patients who prioritize aesthetics. Porcelain can be closely color-matched to adjacent teeth, giving it a natural look. While not as strong as metal crowns, porcelain crowns are durable enough for many applications, especially for front teeth.
Best Material for Dental Crowns
The best material for a dental crown depends on the location and function of the tooth, as well as individual preferences:
- Porcelain and zirconia are best for a natural appearance.
- Metal crowns offer unmatched durability for molars.
- Porcelain-fused-to-metal (PFM) combines strength with aesthetics.
Discussing options with your dentist will help you decide on the best material for your unique needs.
Dental Crowns vs. Veneers
Both crowns and veneers improve a tooth’s appearance, but they differ in purpose and coverage:
- Crowns: Cover the entire tooth and provide structural support, ideal for damaged or decayed teeth.
- Veneers: Cover only the front surface and are primarily used for cosmetic improvements on otherwise healthy teeth.
Dental Crown Pain
A dental crown should fit comfortably; however, it’s common to experience mild discomfort initially. If pain persists or worsens, consult your dentist as it could be due to a bite misalignment, gum irritation, or an infection in the tooth.
Zirconia Dental Crowns
Zirconia crowns are strong, durable, and metal-free, offering an ideal balance of strength and aesthetics. They are highly biocompatible, reducing the risk of allergic reactions or sensitivity, and are increasingly popular due to their long-lasting properties.
Dental Crowns Aftercare
- Oral Hygiene: Continue to brush and floss daily.
- Avoid Hard Foods: Chewing on hard foods or ice can damage the crown.
- Regular Checkups: Routine dental visits help detect any issues early, ensuring your crown remains in optimal condition.
Same-Day Dental Crowns
With CAD/CAM technology, same-day crowns are created and fitted in a single visit. This option saves time and the inconvenience of wearing a temporary crown, although it may not suit all cases, especially complex dental restorations.
CEREC Dental Crowns
CEREC is a brand of same-day crown that uses CAD/CAM technology to create precise, high-quality crowns in one appointment. These crowns offer the convenience of quick placement and are ideal for patients with busy schedules.
Dental Crowns for Children
In pediatric dentistry, stainless steel crowns are often used for primary teeth affected by decay or structural issues. These crowns protect the primary tooth until it naturally falls out and are affordable, durable, and easy to place.
Dental Crown Alternatives
Alternatives include:
- Veneers: Ideal for minor cosmetic improvements.
- Onlays and Inlays: Used for partial tooth coverage when full crowns are unnecessary.
- Fillings: Appropriate for small cavities that do not require the protection of a full crown.
Dental Crowns vs. Fillings
Fillings restore small areas of decay, while crowns cover the entire tooth, offering superior protection and strength for significantly damaged teeth.
Dental Crown Infection Symptoms
If a dental crown becomes infected, symptoms can include persistent pain, gum swelling, and a bad taste. An infection may arise if bacteria infiltrate the space beneath the crown. Consult your dentist promptly if you suspect an infection.
Dental Crown Color Match
For a natural look, your dentist will color-match your crown to your existing teeth. Although close, slight color differences can occasionally appear under certain lighting conditions.
Metal-Free Dental Crowns
Metal-free crowns (such as porcelain and zirconia) are increasingly popular for their natural appearance and reduced likelihood of allergic reactions. These crowns are also aesthetically pleasing, particularly for visible teeth.
