Steps Dentists Take When Filling a Cavity

Metal fillings were common for a number of years before dentists discovered the benefits of composite fillings. Made from a combination of materials, this type of filling will match the shade of any surrounding teeth and strengthen your tooth to keep the cavity from growing. While you might feel a little nervous before your appointment, looking at what will happen during the procedure may help you relax.

Numbing Your Tooth and Gums

Before filling your tooth, the dentist will typically apply a numbing liquid to your tooth and the surrounding gums. Once your mouth is fully numb, the dentist will give you one or more shots of an anesthetic agent that completely numbers your mouth. Most dentists will leave patients for a few minutes to ensure their mouths are numb before proceeding.

Filling the Tooth

Once your mouth is numb, the dentist will use a metal tool to carefully remove any black or brown spots from your tooth and remove all traces of the cavity. The dentist then uses a small paintbrush to carefully fit the hole in your tooth with the composite material. Depending on the size and location of the cavity, the dentist may use brushes to mold the composite materials to your tooth to cover any cracked or jagged edges. When looking for dentists, Las Vegas patients may want to find offices that use lights that help bond the material to their teeth. This reduces the risk that the material might pull away from the tooth’s enamel.

Do You Have a Cavity?

If you have a cavity, you need to get that cavity filled as quickly as possible. Letting it go untreated can let that cavity grow and eventually cause your tooth to break. Though some dentists still use metal fillings, most now use composite fillings. Composite fillings last longer than metal fillings do and will blend with your surrounding teeth instead of sticking out like metal does.
