What is a dental crown?
A dental crown, or “cap,” is a tooth-shaped restoration that is made by a machine. It is designed to cover and strengthen the entire tooth.
Why might I need a dental crown?
Your dentist may recommend a dental crown for a tooth that has had a root canal, or one that has had a large filling, to help keep the tooth strong for biting and chewing. Crowns can also be used to hold a dental bridge in place or to cover a dental implant. A crown may also be recommended to protect a weak, broken, or discolored tooth.
What types of materials are used to make crowns?
Metal Alloy – gives a silver appearance. Metal crowns are very strong and therefore tend to last longer than other crown materials.
Porcelain (including Ceramic and Glass-Like materials) – the most natural looking and the color can be designed to closely match surrounding teeth. Because it is not as strong as metal, porcelain crowns may break or fracture due to heavy biting or grinding.
Porcelain Fused to Metal – Covering a metal crown with porcelain creates a more natural looking crown. The metal provides an additional level of strength to the crown, even though the porcelain may still be prone to fracture.
What is involved in?
Getting a dental crown typically takes two dental office visits. Newton Wellesley Dental Partners uses CAD/CAM technology to help create precise shapes and sizes for dental restoration including bridges and crowns. We use this technology to design the anatomical features, size, and shape of the tooth.
A 3D image of your mouth and gums allows us to draw the precise design of the tooth restoration giving you a perfect fit. This first step creates the “thimble” which sits over the tooth against the gum. Then an artisan layers the ceramic over the thimble in order to create the life-like look.
Will I need a root canal if I get a crown?
No, not all teeth that get crowns need to have a root canal. Typically, teeth that have had a root canal treated do need to have a crown placed on the tooth.
