What are dental crowns?

Put simply, a crown covers most or all of a damaged tooth and is placed over the top of the tooth to protect it from further damage.

Crowns are used in dental procedures primarily over molars and are placed like a cap (or crown) over most of the tooth visible above the gumline. Some indicators that you may need a crown over a tooth include sensitivity or pain while chewing or a feeling of weakness when biting down. Dental crowns are commonly made of gold, porcelain, porcelain fused to metal (PFM), or a new material called zirconium.

Reasons you may need a dental crown

At Tea Tree Dental, we find our patients will consider getting a crown for various reasons. Some of the most common include tooth decay, cracked or broken teeth, weakened teeth, and to cover root canal-treated teeth. We’ve detailed below what might lead you to think about having a crown placed.

Weakening around a large filling

When a filling has been used to replace a large amount of tooth decay, over time, stress cracks can form where the filling is in contact with the remaining tooth. A crown creates a protective barrier over the filling (or replaces it completely) and stops further cracks from compromising the integrity of the tooth.

Post-Root canal

During a root canal procedure, infected or damaged pulp is removed from inside the tooth and replaced with dental cement. Over time this can leave the tooth dry and brittle, so a crown is placed over the top of the tooth to ensure it will be secure and protect it from cracking.

Cracked tooth syndrome

When cracks appear in an otherwise healthy tooth, a crown can be used to stop the damage from getting worse. Sometimes, you won’t even see the crack, but you may notice pain when biting or chewing on that tooth. The crown protects the tooth and stops the pain.

Broken cusps

The cusp is the raised parts of the tooth which are essential in chewing various food types. When a cusp breaks off, this can cause pain as well as structurally weakening the tooth, and the gap left behind can make it harder to chew food successfully.

Excessive wear of teeth

Excessive wear occurs when the teeth are worn down to the point where the enamel is compromised, which can cause sensitivity and weakening. This is common at the cusp of the tooth.

Undesirable appearance of teeth

Stains, gaps, and misalignments may all be addressed with crowns, although other procedures may also be suitable depending on your individual situate and needs.

How we make your same day dental crown

In most situations we will manufacture your crown in our clinic with the aid of our CEREC dental milling machine, and our crowns are either Zirconium or E-Max crowns, depending on your unique circumstances.

Zirconia is considered to be the most durable monolithic ceramic, which is a type of ceramic that is produced without the addition of any other materials. In comparison to glass ceramics and dental composites, zirconia exhibits greater resistance to splitting, stiffness, and strength. These characteristics help prevent the possibility of cracking and chipping, both in the surrounding teeth and the tooth that is located beneath the crown. Additionally, zirconia possesses a superior shielding capacity that enables it to withstand higher loads without compromising your smile.

An E-max crown is a special type of crown made from a lithium disilicate material. These crowns are constructed from a single ingot of lithium disilicate ceramic which makes it an extremely high strength crown and very resistant to chipping. Lithium disilicate is known for its superior strength and appealing life-like aesthetics as a restorative crown material.

Another advantage to an E-max crown isn’t a visible metal base which can give your gums a grey tinge around the gum line, which is always a benefit to patients who may need a crown that will be more visible.

The process of having a same day dental crown placed

Similar to a veneer, a thin layer of the outer tooth usually needs to be removed to make space for the crown to adhere to, and this requires a local anaesthetic to be used.

We then take a 3D digital scan of your mouth, which captures a digital dental impression of your teeth without requiring any impression paste or other traditional materials. We may also perform X-rays as needed and we will inform you if required.

From your digital scan, we can carefully design a precise blueprint for your crown. This digital representation of your tooth means that your crown will integrate seamlessly with your current teeth, ensuring not only will it look good but also be a more comfortable and long-term solution.

Our innovative CEREC technology is used to carefully mill your custom-made dental crown from tooth-coloured ceramic materials, resulting in a result that not only looks natural but also functions flawlessly. We polish your custom-designed dental crown and make sure it fits and the colour is a perfect match before bonding it to your tooth.

Our ability at Tea Tree Dental to manufacture your same day dental crown in-house means you can get your permanent the crown cemented the same day. You may opt to wait at reception for approx. 45mins while we manufacture your crown or come back later in the day for placement. It’s entirely up to you.

The information provided is intended to give you an overview of what to expect, but the best course of action is always to consult with us at Tea Tree Dental to discuss your options today.
