Dental crowns are a procedure, available at our dental clinic in London, to strengthen or improve the appearance of damaged teeth. They are an artificial restoration that’s placed over an existing tooth, which may need to be carefully filed down first, to act as a cap on top of it.
They can be used for many purposes. For example, to preserve a weakened tooth from fracturing, to replace a large dental filling when insufficient tooth is remaining, to protect a tooth after root canal treatment, to hold a dental bridge in place, or to cover a poorly shaped or discoloured tooth.
A dental crown can be made from a range of different materials, with ceramic, porcelain, or porcelain bonded to metal being the most commonly used ones. What material is used for your crown will depend on the reason for needing the crown and the location of the tooth needing the crown.
During the preparation stage, we will note the colour of the teeth either side of the one where the crown will be fitted, and ensure that the colour of the custom crown we make matches those so the final result looks natural.
Two visits to our clinic are normally required for the dental crown procedure to be completed. At the first visit, we will prepare your tooth for the crown, take impressions for the crown, and fit a temporary crown. At the second visit, the temporary crown will be removed and replaced with the permanent one.
The permanent crown will only be fixed permanently in place after you’ve confirmed you’re happy with the colour, shape and fit of it. It will be fixed in place using a special, long lasting dental adhesive. Properly cared for, it should last for many years, with 5-15 years being the average.
A local anaesthetic will be used for the procedure, meaning you will feel no pain. Some level of discomfort is possible, though should be no more than felt when having a filling fitted.
When could my tooth need a crown (cap)?
- Substantial Chips or broken teeth/fillings due to a fall or some other types of trauma.
- Deep tooth decay may also severely weaken a tooth, with a high risk that the tooth may fall apart.
- Root canal treated teeth, which are very weak
- Cosmetic needs, improving tooth strength, function and will often enhance the overall health and appearance of the mouth.
Each type has its own unique advantages and disadvantages.
All-metal crowns are known for their strength and durability. All-ceramics are known for the superior aesthetics they can provide. Porcelain-fused-to-metal crowns offer the middle ground between the two
