Restorations and Fillings Repair Damaged Teeth

Tooth-Colored Fillings Look Like Natural Teeth

Though every patient would love to receive a clean bill of health each time they visit their dentist, widespread consumption of sugary foods and drinks, along with other causes of tooth decay, make cavities (also known as dental caries) unavoidable for most of us.

Professional teeth restorations — commonly known as getting a filling — are a relatively simple and painless dental procedure that helps patients regain tooth integrity and maintain good oral health.

This video shows you how a composite filling restores a damaged or decayed tooth to its natural strength and appearance.

What Is a Filling?

Unlike dental sealants, which are used to fill deep nooks and crannies in healthy teeth to prevent food from becoming trapped and causing the erosion of tooth enamel, fillings are used to fill cavities — essentially holes in your teeth — that result from tooth decay. The filling restores the tooth’s structure and full function. Depending on the material used, a filling can look just like the rest of your natural tooth.

What Are Fillings Made Of?

Types of filling include:

  • Composite fillings. Composite fillings are often preferred by patients today, especially for cavities near the front of the mouth, as the material looks just like natural teeth. The composite is made from powdered glass, quartz, silica, or other ceramic particles, added to a resin base
  • Silver amalgam fillings. Silver amalgam is highly durable and most suitable for filling cavities in the back of the mouth. Amalgam has been used by dentists for more than a century, though its use is dropping due to esthetic reasons, and because the amalgam’s stable alloy contains a tiny amount of mercury. 
  • Gold fillings. Gold is also used for fillings, though less commonly, due to the high cost and esthetic reasons. 
  • Glass ionomer fillings. Glass ionomer is made of acrylic and a specific type of glass material. Glass ionomer is most commonly used for fillings below the gum line and for fillings in young children. Glass ionomers release fluoride, which can help prevent tooth decay from recurring.
  • Ceramic fillings. Ceramic fillings offer impressive durability and great aesthetics. Ceramic fillings are typically made of porcelain and are known to withstand stains and abrasion. This type of filling is ideal for larger cavities in visible areas of the mouth.

If you require a filling, your dentist will recommend the type of filling best suited to your situation.

How Do I Know When I Need a Filling?

Most cavities are detected in an early stage through x-rays, which are conducted on a regular basis at dental checkups. However, if you are experiencing the following symptoms, you may have a cavity:

  • Visible pits or holes in your teeth
  • New sensitivity when eating hot, cold, or sweet foods
  • Toothaches that occur randomly
  • New pain when biting or chewing
  • Signs of gum disease

Cavities don’t always have visible symptoms. This is why it’s important to see a dentist every six months for teeth cleanings. Your dentist can detect early signs of cavities before they cause more damage to your tooth.

What is the Procedure for Getting a Filling?

To receive a composite filling, the area around the tooth will first be numbed. Then the tooth is prepared by removing the decayed portion, leaving a small area that will be filled with the composite.

After a deep clean to remove debris, a special bonding agent is applied to the prepared area. A special curing light is then used to secure the bonding agent.

Your dentist then applies the composite material to the prepared area in layers, shaping the material to match the contours of your tooth’s surface. The curing light is used to set each layer of the composite, hardening it to withstand the forces of opposing teeth.

As a final step, your dentist will polish the composite filling to smoothen it and give it a similar sheen to the rest of your tooth.

Once completed, your tooth is free of decay, and restored to its natural strength and appearance.

Caring For Your Filling

Your filling can last for many years if you maintain proper brushing and flossing. Be sure to brush your teeth at least twice a day with fluoride toothpaste, and floss at least once a day or after every meal. You should also visit your dentist every six months for dental cleaning.
