What are dental fillings?
These restorations are used to restore the structure, function and appearance of a tooth that's been damaged or decayed, alleviating tooth pain you may be experiencing.
Why are dental fillings used?

What are dental fillings made of?
Dental fillings are available in a variety of materials, including amalgam, composite, porcelain, and gold. While each of these materials is safe and long-lasting, they also have their own set of benefits and drawbacks when it comes to repairing a cavity or decay. Our dentists offer guidance on how to make the best dental decision for you.
Porcelain Fillings for Strength & Appearance
Porcelain fillings, also known as inlays and onlays, are brittle, hard, and created in conjunction with metal. These sturdy, tooth-coloured dental restorations, which are created in a dental lab and then delivered back to your dentist for placement, are frequently used on molars because they are more long-lasting and durable than a typical dental filling.
You’ll usually need to attend two dental appointments so your porcelain filling can be placed in your mouth.
Composite Fillings for a Natural Look & Feel
Because they are very similar in colour to natural teeth, composite fillings tend to blend in well with the surrounding teeth.
They look and feel natural, and are popular with patients who are concerned with how amalgam (grey) fillings may appear on teeth that are visible when they smile.
Composites are popular among dentists because they are simple to sculpt and shape onto a tooth and bond naturally to it. This means that when preparing the tooth, your dentist will not have to remove as much existing enamel.
Your dentist will remove tooth decay and add bonding material to the inside of the hole so the filling can be placed. Composite resin is then layered in the hole.
A curing light is used to harden each layer. When the last layer of resin has hardened, the filling will be carefully shaped to match your natural teeth.
Gold Fillings for Durability
A model of your tooth is used to create cast gold fillings. A cast gold filling is produced in a dental lab and delivered back to your dentist. It is made of a mixture of gold and other materials, including copper and silver.
Then, it will be fixed inside your mouth with dental cement. Although this kind of filling is the most expensive, it is also the most durable (usually lasting 20 years or more). Additionally, getting it placed will require at least two dental visits.
