Dental Health and Tooth Fillings

Dental health and tooth fillings are closely linked. Tooth fillings are a common dental procedure used to restore decayed, damaged, or worn teeth. They help to prevent further damage to the tooth, improve chewing function, and restore the appearance of the smile.

Tooth Decay and the Need for Fillings

Tooth decay, also known as dental caries, is a common bacterial infection that causes the breakdown of tooth enamel and dentin. If left untreated, tooth decay can lead to pain, infection, and tooth loss. Dental fillings are used to treat tooth decay by removing the decayed portion of the tooth and filling the cavity with a durable material.

Types of Tooth Fillings

There are several different types of tooth fillings available, each with its own advantages and disadvantages. The most common types of fillings include:

  • Amalgam fillings: Amalgam fillings, also known as silver fillings, are the most durable and long-lasting type of filling. They are made from a mixture of metals, including mercury, silver, tin, and copper.

  • Composite resin fillings: Composite resin fillings are tooth-colored fillings that are popular for their aesthetic appearance. They can be bonded directly to the tooth and can be used to fill both small and large cavities.

  • Glass ionomer fillings: Glass ionomer fillings are a type of tooth-colored filling that releases fluoride, which helps to prevent further decay. They are often used to fill cavities in children’s teeth.

  • Gold fillings: Gold fillings are the most expensive type of filling, but they are also the most durable. They are a good option for people who have allergies to metals or who want a filling that will last for many years.

Benefits of Tooth Fillings

Tooth fillings offer several benefits, including:

  • Prevent further decay: Tooth fillings prevent further decay by sealing the cavity and preventing bacteria from entering the tooth.

  • Restore chewing function: Tooth fillings restore the shape and function of the tooth, making it easier to chew food.

  • Improve appearance: Tooth fillings can improve the appearance of the smile by filling in cavities and restoring the tooth’s natural shape and color.

Care for Tooth Fillings

With proper care, tooth fillings can last for many years. Here are some tips for caring for your tooth fillings:

  • Brush your teeth twice a day with fluoride toothpaste.

  • Floss your teeth once a day.

  • Avoid chewing on hard objects.

  • See your dentist for regular checkups and cleanings.


Tooth fillings are a safe and effective way to treat tooth decay and restore the health and appearance of your teeth. If you have a cavity, talk to your dentist about which type of tooth filling is right for you.
