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[edit | edit source]
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[edit | edit source]
The procedure for a filling generally involves the following steps:
- The dentist will first use a local anesthetic to numb the area around the tooth to be filled.
- Next, a drill, air abrasion instrument or laser will be used to remove the decayed area.
- Once the decay has been removed, the dentist will prepare the space for the filling by cleaning the cavity of bacteria and debris.
- 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.
- After the filling is in, your dentist will finish and polish it.
Risks and Complications[edit | edit source]
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[edit | edit source]
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.
