Dental Crowns and Bridges Crows Nest

If one or more of your teeth has been significantly weakened by tooth decay, tooth breakage or by a traumatic bite pattern, they can often be effectively reinforced against breakage through the placement of a dental crown.

What is a dental crown?

A crown is essentially a cap or cover for your existing tooth, which reinforces it and restores its look and function. A crown is a specialised type of filling, but crowns are much stronger than regular dental filling materials and they offer greater reinforcement for a tooth. Crowns can be constructed from various materials, many of which look very natural in the mouth. Once it has been created, your crown will then be cemented onto the tooth by your dentist. Crown appointments often involve a simple local anaesthetic to the relevant tooth.

The placement of a crown usually involves two treatment appointments:

  1. Preparing the tooth for the dental crown

The tooth is shaped ready for the crown, an impression of the tooth is taken, and a temporary crown is constructed to protect the tooth for the following two weeks while a dental technician constructs the crown. Your dental crown will be custom crafted from the impression taken of your tooth, and will be created in a shade which will blend with your natural teeth, making it look as natural as possible.

  1. Try-in and cementing of the dental crown

Your second appointment involves gently removing the temporary crown and trying-in the crown which has been constructed for you by the dental technician. The height of the crown will sometimes need minor adjustments so the crown can sit in harmony with your bite. If the crown fits well and looks good, your dentist will cement the crown onto the tooth using a suitable dental adhesive material.

What is a dental bridge?

A dental bridge can be used to fill the space above the gum line where a tooth is missing. A bridge is usually constructed by placing a crown on one or two of the teeth around the gap (where a tooth used to be), and attaching a prosthetic tooth to those surrounding crowns to replace the missing tooth. Bridges are also constructed by a dental technician. Alternatives to the placement of a bridge include dental implants and removable partial dentures. Having a bridge placed in your mouth requires the same two appointments as crown placement (preparation, then try-in and cementing).

Why would I need a dental crown?

Dental crowns are a versatile treatment which can help to address a range of issues, including:

Strengthening a weak tooth: If your tooth has been compromised by decay, or other damage, a crown may be used to protect it from further damage, and restore strength to your tooth. This treatment will often be recommended if you have undergone root canal treatment on a tooth.

Anchoring a dental bridge: As mentioned above, dental bridges are anchored in place by a crown or crowns on the surrounding teeth.

Covering a dental implant: Thanks to the wonders of modern dentistry, it is now possible to replace missing teeth with dental implants. A bio-compatible titanium rod is placed into the site of the missing tooth, replacing the root. Once the titanium component has osseointegrated into the jaw, a dental crown is then attached to mimic the look and function of the natural tooth as much as possible.

Aesthetics: Sometimes dental crowns can be used for purely cosmetic reasons. Where there is significant damage to a tooth, dental crowns provide a more comprehensive cosmetic solution than veneers.

Dental crown and bridge care

Caring for you dental crown or bridge is very much the same as caring for your natural teeth. Be sure to brush and floss daily, and attend your regular check-up and clean appointments. Easy!

How long do dental crowns and bridges last?

When they are properly cared for, dental crowns and bridges can last for at least 10 years; there are many cases where they last even longer.

A crown is a specialised kind of dental prosthetic. It’s much stronger than a regular dental filling and offers greater reinforcement for your tooth. Crowns are constructed from various materials, such as ceramic and resin, and can be created to look like natural teeth, both in terms of shape and colour. Crowns can be constructed in gold alloy for some special cases, depending on your discussion with your dentist. Fear not! Your preferences will be front-and-centre in this decision.

A dental bridge is used to fill the space above the gum line where a tooth is missing. A bridge is constructed by placing a crown on one or two of the teeth around the gap. A prosthetic tooth is attached to the surrounding crowns in order to replace the missing tooth and fill the gap. In some cases, your dentist may recommend a dental implant or a removable partial denture instead of a dental bridge.
