How Dental Fillings Can Prevent the Spread of Tooth Decay

Getting dental fillings is an essential part of taking care of your teeth. Some people think dental fillings are a cosmetic procedure, but that’s not true: they’re an important part of maintaining oral health. That’s because dental fillings can prevent the spread of tooth decay and help you avoid more invasive procedures in the long run.

This article explains the cause of tooth decay, how it is treated, the different types of fillings, the treatment procedures and some after-care tips. 

How Tooth Decay Is Formed

A healthy tooth is strong and hard, but the bacteria that cause cavities can weaken it. They can leave a hole in your tooth, making the teeth sensitive to hot and cold foods. The holes cannot be fixed, but they can be treated with filling. If left untreated, the decay can infect the dental pulp, causing excruciating pain and the need for invasive oral procedures like root canal therapy. Or worse, this can result in the loss of a tooth.

Different Types of Dental Fillings

Depending on how much repair is needed, where the filling is placed in your mouth, and how much it will cost, a professional dentist will help you decide the best material suited for the filling

It could be amalgam filling (a mixture of tin, copper and zinc metals for a long-lasting solution or composite resin for a quick fix and small cavities. Regardless, it may be the only option if the decay has worn enough enamel.

The Dental Filling Treatment

When treating a tooth, the dentist will first remove any decay before reshaping it and filling it with a material that fits. The procedure is performed either by hand or with a machine, known as a “restorative abutment,” that uses water and air pressure to pour materials into the tooth.

What to Expect During Fillings

  • You may feel some pressure.
  • You may feel some pain.
  • You may feel some numbness in your teeth, whole mouth, face, head, neck, or hands during or after the procedure.
  • You may feel dizzy or lightheaded during or right after the procedure, which can last for several hours afterward.
  • A temporary filling will be placed first until your permanent filling is ready later that day or within a few days. However, if you have sensitive teeth due to decay and infection inside your tooth (pulp), you may need more than one visit to fully restore your damaged teeth with fillings.

After Getting Your Filling

After your filling is placed, you must ensure that you’re doing everything possible to keep the tooth healthy and strong. You should brush and floss regularly, visit the dentist regularly and avoid sugary foods, hard objects, smoking, and alcohol.
