What is a Dental Crown?
A crown also is known as a cap is a tooth-shaped dental restoration that is used for capping or completely encasing a single damaged tooth or dental implant. Dental crown or dental cap are made from a variety of materials and are permanently bonded to their foundation with dental cement, avoiding the need for tooth extraction, bridges, partials or dentures. Unfortunately, They cannot be used for full-mouth restoration.
Why are Teeth Capped?
They are commonly used to:
- To protect a weak tooth from wear and tear and/or decay from further damage
- To hold a fractured or broken tooth together
- To support a dental bridge
- To restore a tooth after a root canal procedure which prevents from fracturing
- Hide severely discoloured or misshapen teeth when veneers cannot
What are Types of Crowns?
- Porcelain Crowns
Porcelain crowns and bridges are some of the most popular tooth replacements because they look like your natural teeth. The porcelain used in modern day cosmetic dentistry is incredibly durable, so you can chew and brush your teeth without having to worry about damaging your crown. There are more durable options out there, as we will discuss in the next sections, but this is the best option if you want a natural-looking tooth replacement.
- Cast Gold Crowns
While some people like having gold in their smile, others consider it a detraction from their white teeth.Cast gold is the most durable tooth replacement material, but it is also the most expensive. This will give you the best longevity, even if you have to pay a little more to get it done.
- PFM Crowns
PFM stands for porcelain fused to metal. This is a special group of crowns and bridges that offers the best of both worlds. To make inner portion more durable it is made up of metal, while the outer portions are coated with colour-matched porcelain that blends in with your smile. PFM crowns will not work for every situation, but they are a great fit for certain patients.
What is the procedure for Dental Crown?
- Consultation and planning
During the first visit, a dentist will examine the tooth and its root to determine whether or not a crown is a suitable method of restoration and if additional procedures will be required to make it a success. For example, a tooth with a compromised root can cause an infection or injure the tooth’s pulp, in which case a root canal might be necessary. The examination may involve analyzing X-rays and impressions of the patient’s bite. According to smile designing, if capping of teeth is the best option, dentist will start further procedures.
The procedure begins by numbing the tooth with local anaesthesia, followed by preparing the tooth so that it can support the crown. This includes reshaping the tooth by either filing down the enamel or applying a filling to build it up if it is too damaged or decayed. The amount removed or added depends on the type that will be used. To design and manufacture cap a dental impression is taken and sent to the lab.A temporary crown made of acrylic is placed to protect the tooth until you return. It typically takes 2-3 weeks for it to be fabricated.
Between visits, it is important to take care of the temporary cap in order to protect the prep work performed underneath it. The design of the permanent crown is based on the size, shape and condition of the tooth before the temporary crown is placed, so it is important to take a few precautions. It is advised to avoid sticky, chewy or hard foods as it may dislodge the temporary crown.
The process may take more than 2 visits or require longer sessions if your situation requires special procedures such as a root canal, orthodontic treatment or gum treatment.
