Filling

Filling refers to the process of restoring a damaged tooth back to its normal function and shape. When a dentist performs a filling, they first remove the decayed tooth material, clean the affected area, and then fill the cleaned out cavity with a filling material. This procedure closes off spaces where bacteria can enter, preventing further decay.

Types of Fillings

There are several types of fillings, each with their own advantages and disadvantages. These include:

• Amalgam Fillings: These are made from a mixture of metals, including silver, mercury, tin, and copper. They are durable and resistant to wear, making them suitable for use in the back teeth where the most chewing occurs.

• Composite Fillings: Also known as filled resins or composites, these fillings are made from a combination of glass or quartz filler and can be made to match the color of your teeth.

• Porcelain Fillings: Also called inlays or onlays, these fillings are produced in a lab and then bonded to the tooth. They can be matched to the color of the tooth and resist staining.

• Gold Fillings: These are made to order in a laboratory and then cemented into place. Gold inlays are well tolerated by gum tissues and may last more than 20 years.

Procedure

The procedure for a filling generally involves the following steps:

1. The dentist will first use a local anesthetic to numb the area around the tooth to be filled.
2. Next, a drill, air abrasion instrument or laser will be used to remove the decayed area.
3. Once the decay has been removed, the dentist will prepare the space for the filling by cleaning the cavity of bacteria and debris.
4. If the decay was near the root, the dentist may first put in a liner made of glass ionomer, composite resin, or other material to protect the nerve.
5. After the filling is in, your dentist will finish and polish it.

Risks and Complications

While fillings are generally safe and effective, like any medical procedure, they do carry some risk of complications. These can include:

• Tooth Sensitivity: After getting a filling, a tooth may be sensitive to pressure, air, sweet foods, or temperature.
• Tooth Pain and Discomfort: Some people may experience pain or discomfort in the filled tooth or surrounding area.
• Deteriorating Fillings: Over time, fillings can wear away, chip, or crack, necessitating their replacement.

Prevention

The best way to avoid needing a filling is to practice good oral hygiene, including brushing with a fluoride toothpaste, flossing regularly, and visiting your dentist for regular check-ups and cleanings.
