Dental fillings are a type of restorative treatment that addresses dental decay. To understand how fillings work, it helps to think about the structure of your teeth and the constant balance of mineralization and demineralization within your mouth.

The outermost layer of your teeth is a thin, hard layer of tissue called enamel. Your enamel protects the underlying tissue from bacterial infection and decay. Your mouth is constantly filled with a mix of beneficial and potentially detrimental bacteria.

That bacteria can combine with other substances in your mouth and develop into a thin layer of sticky plaque. The bacteria creates acids, and plaque provides the perfect surface for those acids to break down your enamel.

This creates tiny holes in your teeth called cavities. Left untreated, cavities can deepen, eventually reaching the innermost layers of tooth tissue and creating an infection. Dental fillings work to remove decay and restore a smooth and strong tooth surface.

You have several options when it comes to dental filling materials, including:

Gold and silver

Gold and silver are very durable options and also provide a unique aesthetic that many men and women find appealing. They are also the most expensive options.

Amalgam

Metal amalgam fillings are the dark grey fillings that were once the norm. They are very strong, but they are also highly visible. You can often see these fillings when someone smiles, speaks, or laughs. On the plus side, amalgam fillings are the most affordable option.

Composite

Resin composite fillings can be tinted to match the exact shade of your teeth. They are less durable than the other options but are also more affordable than porcelain, gold, or silver.

Porcelain

Porcelain fillings, also called inlays or onlays, create beautiful and natural-looking restorations. They are moderately durable, and are more expensive than amalgam or resin options.

During your consultation, your dentist will discuss the pros and cons of each filling material choice to help you make an informed decision about your treatment plan.

The process of getting a dental filling is straightforward and painless. Your dentist injects a numbing medication to prevent sensation during the procedure.

Next, a laser device, air abrasion tool, or dental drill is used to remove all traces of decay. The newly exposed tissue is cleansed of all bacteria before the filling material is put into place. The final step is to remove any excess filling material and polish it to a smooth surface.

If needed, your dentist can place multiple fillings during the same appointment. To learn more about fillings and which type is right for you, book an appointment online or by phone.
