What Is a Dental Crown?

22 May What Is a Dental Crown?

A dental crown is an individualized cover that covers a tooth damaged or weakened. It is sometimes called a “cap” because it covers the visible part of the tooth and helps restore its shape, strength, appearance and function. The NHS describes a crown as a cap that completely covers a real tooth and is fixed in the mouth. Crowns can be made from metal, porcelain fused to metal, or ceramic.

A crown is used to protect a tooth that is still salvageable, but needs more protection than can be provided by a filling. A crown can be used to rebuild a tooth that has been cracked, broken or badly decayed.

When might you need a dental crown?

A dentist may recommend a crown when a tooth is too weak for a filling alone. This can happen after deep decay, heavy wear, trauma, or root canal treatment. A crown may also be used to improve the look of a tooth that is badly shaped or discoloured.

The Oral Health Foundation explains that a crown restores the tooth’s shape, strength and appearance, and once fitted, it acts like a natural tooth and cannot be removed by the patient. A crown is not always the first option. If the damage is small, a filling may be enough. If the tooth is badly infected or broken below the gumline, other treatment may be needed. This is why a proper dental assessment matters.

How does a dental crown work?

Before fitting a crown, the dentist will prepare it. The dentist will shape the tooth in order to fit the crown properly. After the tooth is prepared, impressions or digital scans are taken. These scans or impressions are used to make a crown that’s shaped and size according to your mouth. It is possible that you will be asked to wear an interim dental crown while the final crowns are being made. Before the crown is cemented, the dentist will examine the bite, the shape, and the appearance. The crown should feel comfortable to chew on once it has been fixed.

What are the types of dental crowns available?

Crowns can be made from different materials. The best choice will depend on your budget, your condition and desire for a natural result.

Ceramic or porcelain crowns are often chosen for visible teeth because they can look very natural. Porcelain fused to metal crowns combine strength with a tooth-coloured outer layer. Metal crowns are very strong and may be used on back teeth where chewing pressure is higher, although they are less natural-looking. Bupa notes that exact crown costs depend on which tooth is being treated and which material is used. Crowns may be available privately or on the NHS if they are considered clinically necessary.

Does getting a crown hurt?

The dentist will usually use local anaesthetic to numb the affected area. You may feel pressure or vibration while the tooth is being prepared. There shouldn’t be any sharp discomfort. It is possible that the tooth or gums will be sore for a couple of minutes following your appointment. This will usually subside. Contact your dentist if you continue to feel pain, have a high bite or are uncomfortable with the crown.

How long will a dental crown stay in place?

It is possible for a crown to last for many years but they are not indestructible. The life expectancy of a dental crown is affected by many factors. These include the material, the fit, your oral hygiene, and your habits such as grinding your teeth. It is important to have a daily routine. Even though a crown protects the tooth, the natural tooth beneath can still become decayed if plaque is built up. It is also important that the gums around the crown remain healthy.Avoid chewing on very hard objects and go to regular dental checks.

Crown vs filling: what is the difference?

A filling repairs a smaller area of damage inside a tooth. A crown covers the whole visible part of the tooth. If too much tooth structure is missing, a large filling may not be strong enough. In that case, a crown gives extra support by wrapping around the tooth. Imagine a filling or crown as a repair and as a protective covering. Both are helpful, but are used to repair different levels of damage.

Crown vs Veneer: Are they the Same?

No. A veneer is usually used to cover only the front of a tooth. It is mostly for cosmetic reasons. Crowns are used to cover the whole tooth, and improve both the appearance and strength of the teeth. A veneer can enhance the look of healthy teeth. If the tooth is cracked or heavily filled, a crown may be more suitable.

What is the cost of a British crown?

The cost of a crown can vary depending on whether you buy one privately or get it from the NHS. NHS crowns are available when clinically necessary, while private crowns provide more options for materials and appearance.Bupa says that NHS crowns can be obtained if they are considered to be clinically necessary. Private costs will vary based on the tooth type and the material used. Private crowns usually cost more because there may be more material choices, lab options and aesthetic planning. Your dentist should always explain the cost before treatment starts.

Salisbury services

In Salisbury, local dental practices can provide crown assessments, routine check-ups, fillings, hygiene care and restorative treatment for damaged or weakened teeth. If you think you may need a crown, a dentist can examine the tooth, take X-rays if needed, and explain whether a filling, crown, onlay or another option is best. Salisbury patients can also discuss private crown materials, NHS suitability where available, and long-term care to help protect the treated tooth.

Final thoughts

A dental crown, also known as a cap or capule, is a custom-made cap that protects and rebuilds a damaged tooth. It can restore the appearance, improve chewing and protect weak tooth structure. It is not a treatment that fits all. The best treatment depends on the amount of tooth left, whether or not the nerve is still healthy, and how you want to proceed.

If a dentist recommends a crown, ask why it is needed, what material is best, how long it may last, and what the full cost will be. A well-planned crown can be a very useful way to save a tooth and keep your smile working comfortably.
