Dental Fillings

What Are Dental Fillings?

Dental fillings are materials used to fill cavities or repair damaged teeth. They restore the tooth's function and shape while preventing further decay. Fillings can also be used to repair cracked or broken teeth and teeth that have been worn down from misuse.

When Are Fillings Needed?

Dental fillings may be recommended in the following situations:

• To treat cavities caused by tooth decay
• To repair cracked or broken teeth
• To restore teeth that have been worn down
• To fix teeth that have been damaged by nail biting or tooth grinding
• To replace old fillings that have worn out or fallen out

Types of Dental Fillings

There are several types of dental fillings available, each with its own advantages:

Composite Fillings

Composite fillings are made of a resin material that can be matched to the color of your natural teeth. They are popular for their aesthetic appeal and are often used for front teeth or visible areas. Composite fillings bond directly to the tooth, providing good support.

Amalgam Fillings

Amalgam fillings are made from a mixture of metals including silver, mercury, copper, and tin. They are very durable and cost-effective, making them a good choice for back teeth where chewing forces are greatest. They are silver in color and more noticeable than composite fillings.

Gold Fillings

Gold fillings are made from gold alloy and are very durable, lasting 10-15 years or longer. They are well-tolerated by gum tissues and may last longer than amalgam fillings. However, they are more expensive and require multiple visits to place.

Ceramic Fillings

Ceramic fillings are made of porcelain and are very durable and aesthetically pleasing. They can be matched to the color of your teeth and are resistant to staining. They are more expensive than composite fillings and may require multiple visits.

The Filling Procedure

Getting a dental filling typically involves the following steps:

Numbing the Area

Your dentist will first numb the area around the tooth to be filled using a local anesthetic. This ensures you won't feel any pain during the procedure.

Removing Decay

Using a drill or laser, your dentist will remove the decayed portion of the tooth. The area will be cleaned to remove bacteria and debris.

Placing the Filling

The filling material will be placed in the prepared cavity. For composite fillings, the material is applied in layers and hardened with a special light. For amalgam fillings, the material is packed into the cavity and shaped.

Finishing

Your dentist will trim and polish the filling to ensure it fits properly and feels comfortable. They will also check your bite to make sure the filling doesn't interfere with chewing.

Caring for Your Fillings

To keep your fillings in good condition and prevent future cavities:

• Brush your teeth at least twice a day with fluoride toothpaste
• Floss daily to remove plaque between teeth
• Limit sugary foods and drinks
• Visit your dentist regularly for checkups and cleanings
• Avoid chewing hard foods or ice that could damage the filling

How Long Do Fillings Last?

The lifespan of a dental filling depends on the type of material used and how well you care for your teeth. On average:

• Composite fillings: 5-10 years
• Amalgam fillings: 10-15 years
• Gold fillings: 15-20 years
• Ceramic fillings: 15+ years

When to Replace Fillings

Fillings may need to be replaced if they:

• Show signs of wear or damage
• Have developed new decay around the edges
• Are causing pain or sensitivity
• Have fallen out or become loose
• Are cracked or broken
