What They Are:
A dental crown is a tooth restoration constructed in a dental laboratory. Crowns are custom made and fit over your prepared natural tooth and are available in many different materials to aid function and appearance. Here at Confidental Clinic, Clapham Junction, Battersea, our dental surgeons will discuss your options with you depending on your individual requirements.
Crowns are required or advised for various reasons including:
- Protecting a weakened tooth at risk of further fracture due to either substantial tooth loss, heavily restored, root canal treated etc
- Restore teeth with a poor aesthetic appearance where white fillings or veneers cannot be treated
- Replace existing crowns with poor aesthetic appearance or poor function
- Restore Dental Implants
Type of Crowns Available:
Meet the highest standards in both aesthetic and function. Zirconia is a very strong metal free substance which can be used anywhere in the mouth, able to withstand pressure of biting on the front teeth and chewing with the molar teeth.
EMAX is highly regarded as a crown restoration. It is formed of lithium disilicate glass ceramic which is translucent, durable and strong. EMAX is a composition which was specifically designed to replicate a natural tooth in both aesthetics and strength.
- All Porcelain
Pure porcelain gives the natural translucent appearance desired for restorations. Mostly used for treatment on front teeth due to their aesthetic value.
Most cost effective of the metal free crowns. They are strong and have high-wear resistance. Due to their metal free composition they are more naturally aesthetic than bonded metal crowns.
- Porcelain Bonded to Metal
The substructure is made of metal and porcelain is then bonded to the outer surfaces. These crowns are strong and robust therefore ideal for restorations on patients who present with heavy bites.
You will require an initial assessment and consultation to determine the need for crown restoration and discuss your options available. During the assessment, your Dental Surgeon may take pre-treatment photos and radiographs. In some cases, mainly for multiple or front teeth restorations, your dentist may suggest a diagnostic wax up. This involves taking impressions and constructing study models of the teeth. A layer of wax is then placed over the intended prepared teeth on the models demonstrating the proposed restorations allowing you to view the intended treatment plan.
The tooth/teeth to be restored are prepared, involving removing the outer layer of the tooth and any decay present leaving a stable core. Impressions are then taken and sent to the laboratory to hand make the crown restorations according to your individual prescription. This usually takes 10 to 14 days. During this time, you will have a temporary crown in place so the prepared tooth will be protected and aesthetically sound and not left exposed.
Once the crown has been constructed, the temporary crown is removed and the tooth is cleaned. Your dentist will place the custom made crown, examine the fit, occlusion and appearance with you ensuring you are content with the final result before cementing in place.
How many appointments will I need?
On average, from start to finish, you will require 3 appointments including:
- Examination & consultation
- Preparation and impressions
- Restoration fit appointment
In some cases, if there are multiple crown restorations or if a diagnostic wax up is advised for further consultation, then more appointments may be required and your Dental Surgeon will advise you of the proposed appointments.
Will I be left without a crown between appointments?
No, following preparation of the tooth to be crowned, your Dental Surgeon will construct a temporary crown to cement in place until your laboratory crown is fitted. The temporary crown will protect the prepared tooth and be aesthetically pleasing also.
How do I take care of my crown restoration?
It is important to adhere to a good oral hygiene regime, ensuring daily interdental aids are used between crown restorations. Even though the crown itself will not decay, the gum line will need to be kept free of bacteria & debris to prevent gum disease & to protect your natural tooth underneath the crown from forming decay or becoming infected. Ensuring a good dental hygiene regime will promote your restoration in appearance and longevity.
