What Are Dental Fillings? How They Protect Your Teeth from Tooth Decay

What Are Dental Fillings?

Dental fillings are special materials that dentists use to repair teeth. When a tooth has a cavity, a filling helps restore its shape and function. In fact, dental fillings are the first line of defense against tooth decay. They stop decay from spreading and help keep your mouth healthy. Most people will need a filling at some point in their lives.

Why Are Dental Fillings Important?

Tooth decay is a common problem. According to the World Health Organization (WHO), it affects billions of people worldwide. However, dental fillings can prevent small cavities from turning into bigger problems. When you get a filling early, you avoid pain, infection, and even tooth loss. Also, fillings help you chew and speak better. For these reasons, dentists recommend treating cavities as soon as possible.

Types of Dental Fillings

There are several types of dental fillings. Each type has its own benefits. Your dentist will help you choose the best one for your needs. Here are the most common types:

Composite resin: Tooth-colored and blends in well. Many people like this option for front teeth.

Amalgam: Silver-colored and very strong. Dentists often use these for back teeth.

Ceramic: Made from porcelain, these are durable and look natural.

Gold: Long-lasting but more expensive. Some people prefer gold for its strength.

Glass ionomer: Releases fluoride, which helps protect teeth. Often used for children or small fillings.

Symptoms and Signs That May Require a Dental Filling

Sometimes, you may not notice a cavity right away. Still, there are signs that you might need a dental filling. Watch for these symptoms:

Toothache or pain when biting

Sensitivity to hot, cold, or sweet foods

Visible holes or dark spots on your teeth

Rough or chipped areas you can feel with your tongue

Food getting stuck in certain spots

If you notice any of these signs, it is important to see a dentist soon. Early treatment can save your tooth.

Diagnosis: How Dentists Determine the Need for a Filling

Dentists use several methods to check for tooth decay. First, they will ask about your symptoms. Next, they will examine your teeth with a small mirror and probe. Often, dentists use X-rays to see hidden decay between teeth. If they find a cavity, they will recommend a dental filling. Sometimes, they may suggest other treatments if the decay is severe.

The Dental Filling Procedure: What to Expect

Many people feel nervous about getting a filling. However, the process is quick and simple. Here is what usually happens:

The dentist numbs the area around your tooth.

They remove the decayed part of the tooth.

Next, they clean the space to remove bacteria and debris.

Then, they place the filling material and shape it to fit your tooth.

Finally, they check your bite and polish the filling.

Most fillings take less than an hour. After the procedure, you can return to your normal activities.
