Dental crowns: Durability and natural aesthetics

A dental crown is recommended when a tooth is too weak to be restored with a simple filling. This may be necessary in cases of advanced decay, tooth fracture, severe wear or after root canal treatment. It can also be used for aesthetic purposes, notably to correct the color or shape of a tooth, or to support a prosthesis such as a bridge. At Cabinet Dentaire de Thônex, we analyze every situation to determine the best solution for you.

A dental crown restores a tooth to its natural shape and strength. It protects the underlying tooth against fracture and bacterial infiltration, reducing the risk of further complications. Modern crowns are also designed to integrate perfectly with the dentition, both aesthetically and functionally.

The choice of material depends on a number of criteria, including tooth location, aesthetic requirements and desired durability.

• Pure ceramic crowns: Ideal for visible teeth, they offer optimal aesthetic results thanks to their natural translucency.
• Metal-ceramic crowns: more resistant thanks to a metal core, these crowns combine strength and esthetics, although a slight metal edge may become visible over time.
• Metal crowns: Very durable, they are often used for molars, where aesthetics are less important.
• Partial crowns (ceramic onlays): A conservative alternative that preserves part of the natural tooth structure.

During your consultation at Cabinet Dentaire de Thônex, we’ll explain the different options in detail to help you make the choice that best suits your situation.

A dental crown is fitted in several stages. At the first appointment, we prepare the tooth by lightly trimming it under local anaesthetic to ensure a perfect fit for the future crown. A digital or traditional impression is then taken to design a custom crown. While waiting for the final crown, a temporary crown is placed to protect the tooth. At the second appointment, the final crown is precisely fitted, then permanently cemented to ensure optimum retention and lasting comfort.

No, crown placement is performed under local anaesthetic, which guarantees a pain-free procedure. After the procedure, slight sensitivity may occur for a few days, particularly to hot and cold, but this quickly disappears. If discomfort persists, a minor adjustment can be made to ensure perfect contact between the crown and neighboring teeth.

The longevity of a crown depends on the material used, the patient’s oral hygiene and eating habits. On average, a well-maintained crown can last between 10 and 20 years, or even longer. To prolong its lifespan, it’s essential to maintain good oral hygiene and have regular check-ups at the Cabinet Dentaire de Thônex.

Dental crowns should be cared for in the same way as natural teeth. Careful brushing twice a day and the use of dental floss or interdental brushes are recommended to prevent plaque build-up. It is also advisable to avoid chewing excessively hard foods, especially with a pure ceramic crown. Regular visits to your dentist allow you to check the condition of the crown and carry out a professional cleaning if necessary.

In rare cases, a crown may come loose, for example as a result of excessive chewing on hard food, or due to wear of the bonding cement. If this happens, it’s important not to attempt to reattach the crown yourself, and to contact Cabinet Dentaire de Thônex immediately for safe reinstallation.

A crown completely covers the tooth, protecting it from external aggression and reducing the risk of fracture or infection. However, the underlying tooth can still be prone to decay if oral hygiene is inadequate. So it’s crucial to keep your teeth in good condition and visit your dentist regularly to prevent any complications.

Dental crowns cover the entire tooth, while veneers cover only the visible surface. Veneers are mainly used for aesthetic reasons, such as aligning or improving tooth color, while crowns are indicated for damaged or fragile teeth requiring reinforced protection.

A well-fitted crown should be comfortable to wear and integrate perfectly with your teeth. If you experience discomfort when chewing or a sensation of abnormal height, a slight adjustment may be necessary.
