A dental crown or a cap is a type of restoration that completely covers a weak tooth above the gum line and protects it. It can be tooth supported or dental implant supported. It usually takes two visits to complete. Dental crowns can be made of metal – gold, or a metal core with porcelain facing. Alternatively, cosmetic dental crowns can be made in full of porcelain and zirconia.
What are the benefits?
- Strength and comfort – A crown is strong replacement to a large filling or teeth with large cavity or cracks and can look and feel exactly like a natural tooth.
- Aesthetic – The colour and shape can be matched to your own teeth. Crowns can improve the appearance of misshapen or discoloured teeth.
- Long term predictability – Depending on the strength of the tooth underneath, a dental crown can last for many years if you look after your mouth and teeth and the crown is not accidentally damaged.
What will the dentist do?
- Normally, the treatment starts by administering local anaesthesia to numb the area. The treatment is painless.
- The tooth is shaped so that, with the crown, it will be the desired shape and size as a normal tooth. Preparation time will depend on how damaged the tooth is and whether it needs to be built up with a filling first.
- Then, a soft mouldable material is used to make an exact ‘impression’ of the tooth that is to be crowned and the nearby teeth. A specialist dental technician delegated the task of making the crown the exact colour, height and size needed.
- A thin cord may be used to hold the gum away from the tooth so that the impression is accurate round the edges.
- A temporary dental crown made of plastic or metal is put over the tooth until the crown is made. You can chew on a temporary crown but it won’t be as strong as the finished product.
Second visit: When the crown is fitted it might need small adjustment to make sure that it fits perfectly. Then the crown is tried on first, and then glued in place.
In the case of dental implant, the specialist dentist has the option of placing an abutment – post- in the dental implant and the dental crown can then be glued on the top.
Alternatively, the crown can be screwed into the dental implant.
What is the dental crown cost ?
The work undertaken at my practice is always provided to the highest standards. However, the cost of crown varies depending on:
- The complexity of the case.
- The material used.
- The laboratory procedure.
Dental crowns once done properly to a high standard are very successful treatment. The more of sound tooth structure present the better the prognosis of the tooth.
There are many variables that determine “how long” cosmetic dental crowns can be expected to last. Among these are some of the factors mentioned in preceding paragraphs. Additionally, general health, good oral hygiene, regular dental checkups, diet, etc. can affect longevity. Because of this, no guarantees can be made or assumed to be made.
In order to replace decayed or otherwise traumatized teeth, it is necessary to modify the existing tooth or teeth so that crowns (caps) may be placed upon them. Tooth preparation will be done as conservatively as practical.
In some case this may cause teeth sensitivity and in sever cases, root canal treatment maybe needed.
In addition, There is a small risk of the dental crown may de-bond (i.e. come off). If this happens we merely bond it back on. Just keep the crown secure and bring back on your visit to the Clinic. Please note, there maybe charges for this.
