What Type of Materials Are Used in Dental Restorations?

Dental restorations help individuals regain oral functions like chewing and achieve better smiles. Although dentists' skills and experience are necessary to achieve favorable results, material choices contribute significantly to patient satisfaction.

What are some standard dental restoration treatments?

Dentists consider the location of teeth in the mouth and patients' input when selecting materials for dental restorations.

Dentists aim to restore the function and appearance of damaged or missing teeth due to cavities, gum disease, trauma, or wear. Standard restoration procedures include:

• Fillings
• Crowns
• Implants
• Bridges
• Inlays and overlays
• Veneers

What materials do dentists use to restore teeth?

Choosing an appropriate restoration material depends upon balancing function, appearance, and patients' costs. Dentists can choose from traditional and new materials to address oral health and aesthetic concerns.

Gold

Few materials have the longevity and durability of gold, a traditional choice for simple fillings, inlays, overlays, crowns, and bridges. Although gold is soft, it becomes exceedingly strong when mixed with other metals. Dentists recommend gold to restore teeth used for heavy chewing; however, many dental patients prefer more neutral-looking materials for restoring prominent anterior teeth.

Amalgam

Mercury, tin, copper, and silver are mixed to create a low-cost, durable cavity-filling amalgam that withstands heavy chewing. Although amalgam fillings last many years, patients may consider the silver color and tooth discoloration that usually accompanies them a significant downside. Still, the material remains a popular choice for restoring posterior teeth, which are not visible.

Porcelain

Porcelain is beneficial for dental restorations, including fillings, crowns, inlays, overlays, bridges, and veneers. This biocompatible material resembles natural enamel and dentin, has a natural tooth color, and withstands normal chewing. However, dentists may not recommend porcelain restorations for patients with bruxism because excessive tooth grinding will potentially damage the porcelain.

Resin

Dentists may use plastic and powdered glass resin composite to fill cavities. Using this material requires the removal of less of the natural tooth compared to amalgam. Resin also insulates sensitive teeth and is practical for inlays, overlays, and gaps between teeth because it is malleable and natural-looking. Still, resin composite can stain permanently, necessitating periodic replacement.

Titanium

Dentists favor titanium for dental implants to replace missing tooth roots because it is biocompatible and can easily fuse with the natural bone surrounding it. Titanium is also corrosion and crack-resistant, working well as the abutment material that extends through the gum to support the crown during heavy chewing and biting.

Zirconia

Zirconia is a robust alternative to titanium for patients who want implants but are allergic to metal. Its properties enable a one-piece implant and abutment, which insulates sensitive dental tissue from bacteria. Zirconia also produces natural-looking crowns and dental bridges; however, although the material resists damage, it is challenging to manipulate, making it an expensive restorative material.

Lithium Silicate

Lithium silicate or glass-ceramic is an excellent choice for fillings, overlays, inlays, and veneers due to its natural tooth-like translucency and thin profile. Dentists also use lithium silicate to produce convenient, same-day crowns with the help of CAD/CAM machines that can carve them to precise specifications.
