What is a Dental Crown?

A dental crown is a custom-made tooth-shaped cap that’s designed to cover a damaged tooth, restoring the tooth’s function and appearance. It’s often used when a tooth has been severely damaged by decay, a fracture, or wear. Crowns are also used to protect weak teeth, complete dental implants, or improve the look of discoloured or misshapen teeth.

At Totalcare Dental and Dermal, we offer different types of dental crowns to restore your smile, your teeth’s function, and your confidence! Ask us about them today.

How does a Dental Crown Help?

A dental crown helps to improve the appearance and functionality of the tooth. It restores the tooth to its original size, shape, and strength, so it looks and works like normal. Aside from that, it can also help protect weak or damaged teeth from further damage, and may even be used to keep dentures or a dental bridge in place.

What are Dental Crowns Made of?

Ceramic Crowns

Ceramic crowns are made entirely of ceramic material, which can be colour-matched to blend with your other teeth. They’re popular for their natural appearance and are especially useful for front teeth, because they’re practically indistinguishable from natural teeth.

Another benefit of ceramic crowns is that they’re biocompatible. This means they’re not harmful to the surrounding tissue, so there’s very little chance of you developing an allergic reaction.

Porcelain

Porcelain crowns offer the most natural look, not only matching the colour but also the translucency of natural teeth. They’re ideal for front teeth, but may not be as strong as other materials for back teeth.

With proper care, porcelain crowns can last between 5 and 15 years. These crowns are also biocompatible, and they tend to be resistant to staining.

Porcelain-Fused-to-Metal (PFM)

Combining the strength of metal with the aesthetics of porcelain, PFM crowns are a good option for both front and back teeth. They consist of a thin metal shell inside, and a porcelain shell on the outside.

PFM crowns can lead to some problems, though. Firstly, you may have an allergic reaction to the metal, although this is rare. Secondly, as your gums naturally recede over time, a thin grey metal line may become visible between the crown and the gum.

Zirconia

Zirconia is stronger than porcelain and non-toxic. It’s an excellent choice for individuals who have a high bite force, because it can withstand more pressure than other materials. However, it’s more expensive than other types.

Reasons for Getting a Dental Crown

Dental crowns are a common solution for various dental issues. Here are some reasons why you might need a dental crown:

• Protect a Weak Tooth: If you have a tooth that’s cracked, decayed, or weakened, a crown can help hold it together and prevent further damage.
• Restore a Broken Tooth: A dental crown can restore the shape, size, and function of a tooth that’s severely worn down or broken.
• Support a Dental Bridge: When you have a missing tooth, a dental bridge can fill the gap. Crowns are used on the adjacent teeth to support the bridge.
• Complete a Dental Implant: Crowns are often used to complete dental implants, providing a natural look and feel while restoring function to the tooth.
• Improve Appearance: If you have a misshapen or severely discoloured tooth, a crown can improve its appearance. Crowns can be custom-made to match the colour and shape of your natural teeth.
• After Root Canal Therapy: Teeth that have undergone root canal therapy are often left brittle and prone to cracking. A crown can protect and strengthen the tooth.
• Prevent Further Damage: Crowns can help in situations where fillings or other types of repairs wouldn’t be enough, providing a long-term solution for dental health.

Signs You Need a Dental Crown

Recognising the signs that you might need a dental crown is important for maintaining your oral health. The sooner you get a crown, the less damage your teeth will take on. Here are some indicators to watch out for:

• Persistent Tooth Pain: Continuous pain, especially when chewing or biting, can signal that a tooth needs more than a filling or minor repair. A crown can relieve the pain by protecting the damaged tooth.
• Visible Cracks or Chips: If you notice cracks or chips in your teeth, it may be time for a crown to prevent further damage and restore functionality.
• Large Fillings: Teeth with large fillings are more likely to crack or break. A crown can provide extra support and protection.
• Severe Wear and Tear: Grinding your teeth (bruxism) or other habits can wear down your teeth. Crowns can restore their structure and strength.
• Sensitivity to Hot or Cold: Increased sensitivity to temperature changes might indicate that your tooth’s enamel is worn down or that there’s decay. A crown can cover and protect the sensitive areas.
• Gum Disease: Advanced gum disease can cause teeth to become loose or shift. In some cases, crowns are used as part of the treatment to stabilise these teeth.
• Failed Previous Dental Work: If a filling, inlay, or onlay has failed, a crown may be the next best step to protect the tooth and reestablish its natural function.

Dental Crown Procedure: What to Expect

The full dental crown procedure requires three separate visits to the dentist. Here’s what to expect if you’re thinking about getting dental crowns.

1. Initial Dental Visit and Examination

Your dentist will have a close look at the tooth and the surrounding teeth and decide whether a dental crown is the best choice for you. Depending on the condition of the problem tooth, they may take X-rays to get a better look at the bone and the tooth root.

2. Dental Crown Procedure

Once your dentist has given you the go-ahead for a dental crown, you’ll move on to the actual procedure for getting your crown.

3. First Dental Crown Appointment

The first dental crown visit is a preparatory visit. Your dentist will examine your teeth and prepare it for the crown by gently filing down the top layer of the tooth. Placing crowns without removing the top layer might be difficult, as this makes space for the thin crown layer.

Then, a digital impression of your tooth is taken. This is the blueprint for creating a custom-shaped crown that fits on your teeth like a glove. It’ll be sent off to the dental lab, where experienced technicians will design and manufacture your permanent crown.

Before you leave this appointment, your dentist will place a temporary crown. This protects your now-exposed tooth, but it also gives you time to adjust to the feeling of the crown over your teeth.

4. Second Dental Crown Appointment

Once your crown is ready, you’ll return to the dentist for it to be placed. The temporary crown will be removed and the new one fitted. After your dentist has confirmed that it’s a perfect fit, they’ll cement it in place.

How to Care for Your Dental Crown

Routine Dental Care Practices

Taking proper care of your dental crown will make it last longer, but it also plays a role in maintaining good oral health. Here are some routine dental care practices to follow:

• Brush Twice Daily: Use a soft-bristled toothbrush and fluoride toothpaste to clean your teeth and crown thoroughly. Make sure to brush for at least 2 minutes each time to remove plaque and prevent decay around the crown.
• Floss Daily: Flossing helps remove food particles and plaque from between your teeth and around the crown. Be gentle to avoid damaging the crown. Consider using a floss threader or interdental brushes for easier access.
• Use an Antibacterial Mouthwash: Rinse with an antibacterial mouthwash daily to reduce the risk of infection and gum disease. This helps keep the area around your crown clean and healthy.
• Visit Your Dentist Regularly: Schedule regular dental check-ups and cleanings every 6 months. Your dentist will check the integrity of the crown and make sure it remains securely attached. They can also spot any potential issues early on.

What to Avoid After Getting a Dental Crown

After getting a dental crown, certain habits and foods can jeopardise its stability and your overall dental health. Here’s what you should avoid:

• Chewing Hard Objects: Avoid chewing on hard objects like ice, pens, or fingernails. These can crack or dislodge your crown. Stick to softer foods and be mindful while eating.
• Sticky Foods: Foods like caramel, chewing gum, and toffees can stick to your crown and potentially pull it off. If you must eat these types of foods, do so with caution and avoid using the crowned tooth.
• Using Teeth as Tools: Never use your teeth to open bottles, tear packaging, or cut thread. This can cause severe damage to your crown and natural teeth.
• Grinding and Clenching: If you grind or clench your teeth, especially at night, it can put excessive pressure on your crown. Consider using a night guard to protect your teeth and crown from damage.

Advantages of Dental Crowns

Restores Functionality

Dental crowns can restore the functionality of a damaged or decayed tooth. By covering the entire tooth, a crown allows for normal chewing and speaking, which might be difficult with a broken tooth.

Protects Weak Teeth

Crowns add a protective layer to weak teeth that are at risk of breaking. This is especially useful for teeth that are very decayed or have had large dental fillings.

Improves Appearance

Dental crowns can improve the appearance of your teeth quite noticeably. They’re often used to cover up discoloured or misshapen teeth, giving you a smile you can be confident and happy about.

Durable and Long-Lasting

Crowns are made from strong materials like porcelain, metal, or ceramic, making them durable and long-lasting. With proper care, a crown can last between 10 and 15 years, or even longer.

Supports Dental Work

Crowns are often used to support other dental work. They can hold a dental bridge in place or cover a dental implant, keeping them stable and functional.

Customisable Fit and Appearance

Dental crowns are custom-made to fit perfectly over your teeth. They can be almost perfectly matched to your existing tooth colour, making them look natural.

Disadvantages and Risks of Dental Crowns

Cost

Dental crowns can be expensive, especially if they’re made from high-quality materials like porcelain, zirconia, or gold. Insurance may only cover part of the cost, or nothing at all, if they consider the process to be unnecessary.

Preparation Process

The process of preparing a tooth for a crown involves removing a significant amount of the tooth structure. This can be uncomfortable.

Sensitivity

Some patients experience increased tooth sensitivity to hot or cold temperatures after getting a crown. Usually, this eases with time.

Potential for Damage

Although crowns are durable, they can still chip or crack, especially if you grind your teeth or bite down on hard objects. Being careful can lower the risk, but there’s still a chance for damage, which would then need to be replaced.

Allergic Reactions

In rare cases, some people may have an allergic reaction to the materials used in the crown. This happens most often with metal crowns.

Decay Underneath the Crown

If you don’t maintain proper oral hygiene, decay can develop under the crown. This can lead to bigger problems and may end up needing the crown to be removed to treat the problem below.

How much does a Dental Crown Cost?

There are several types of dental crowns, each with different costs and benefits:

Terms & Conditions: Pricing is indicative only of an average cost. Pricing can vary depending on the medical condition and requirements of the patient, as well as the materials used.

Factors Affecting the Cost of Dental Crowns

• Location of the Dental Clinic: Dental costs can vary significantly depending on whether you’re in a major city or a regional area. Urban areas tend to have higher prices due to the higher cost of living and operating expenses.
• Dentist’s Expertise: Experienced dentists or specialists may charge more for their services. The quality of care and the technology used in the procedure can also impact the cost.
• Additional Procedures: Sometimes, extra dental work is required before placing a crown, such as root canal treatment or dental implants.
• Insurance Coverage: If you have private health insurance, it might cover part of the cost of a dental crown.

What are the Alternatives to Dental Crowns?

There are several alternatives to dental crowns, depending on the condition of the tooth and the desired outcome:

• Dental Bonding: This involves applying a tooth-coloured resin to the tooth and shaping it to restore its appearance. It’s less invasive than a crown and can be a cost-effective solution for minor repairs.
• Veneers: Thin shells made of ceramic or composite material are bonded to the tooth’s front surface. Veneers are a good option for improving the appearance of front teeth with minor damage or discolouration.
• Inlays and Onlays: These are used for teeth that are too damaged for a filling, but not damaged enough for a crown. They’re made from porcelain or composite resin and are bonded to the tooth.
• Dental Implants: For severely damaged or missing teeth, implants are a durable and long-lasting solution. They involve surgically placing a titanium post in the jawbone, which acts as a root for a new tooth.
• All-Ceramic Bridges: These can replace missing teeth without using adjacent teeth as anchors, to provide a natural look and strong support.

Each alternative has its benefits and considerations, so it’s important to consult with your dentist to determine the best option for your specific needs.
