Dental fillings are a fundamental aspect of dental care, and a service we provide often at Waterdown Smiles Dentistry, yet many people have only a basic understanding of what they are and how they work.
This post aims to shed light on the world of dental fillings, explaining their purpose, the different types available, and what you can expect during and after a filling procedure. Whether you’re about to get your first filling or just curious about the process, this guide will provide you with a comprehensive overview.
The Purpose of Dental Fillings
Combating Tooth Decay
Dental fillings are primarily used to repair damage to the structure of a tooth caused by decay or trauma. When a tooth is decayed, the affected and weakened part of the tooth is removed, and a filling is placed to restore the tooth to its original shape and function.
Preventing Further Decay
By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Regular checkups are important, however, as decay can occur under and around the filling over time.
Types of Dental Fillings
Dental technology has evolved significantly, offering various materials for dental fillings. Each type has its advantages and drawbacks, and the best choice for you can depend on the extent of the repair, allergies to certain materials, where in your mouth the filling is needed, and cost.
1. Amalgam Fillings
Amalgam has been used by dentists for over a century. These fillings are strong and ideal for filling cavities in the back teeth, where the chewing pressure is greatest. They’re less expensive than other types and can last 10 to 15 years or more. However, their dark color makes them more noticeable than porcelain or composite restorations and less aesthetically pleasing.
2. Composite Fillings
Also known as filled resins, composite fillings are a mix of glass or quartz filler in a resin medium that produces a tooth-colored filling. They are well-suited for use in front teeth or visible parts of teeth. Composite fillings provide good durability and resistance to fracture in small-to-midsize restorations and can be bonded or adhesively held in a cavity.
3. Porcelain Fillings
Porcelain fillings, also known as inlays or onlays, are produced in a lab and then bonded to the tooth. They can be matched to the color of the tooth, resist staining, and cover most of the tooth. Their cost is similar to gold.
4. Gold Fillings
Gold fillings are made to order in a laboratory and then cemented into place. Gold inlays are well-tolerated by gum tissues and can last more than 20 years. Many people find gold more pleasing to the eye than silver amalgam fillings, but it is often the most expensive choice.
The Dental Filling Procedure
The Process
The process of getting a filling can typically be completed in one dental visit. Here’s what you can expect:
- Local Anesthesia: To numb the area around the affected tooth, your dentist will apply a local anesthetic.
- Removing Decay: The dentist will remove decay from the damaged tooth using a drill, air abrasion instrument, or laser.
- Testing: The dentist will probe the area to determine if all the decay has been removed.
- Preparation: The space for the filling will then be thoroughly cleaned to remove bacteria and debris.
- Filling Placement: If the decay is near the root, your 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.
- Adjustments: Additional appointments may be required to check the fit of the filling and make adjustments.
Aftercare
Sensitivity immediately after having a tooth filled is common. You might experience sensitivity to pressure, air, sweet foods, or cold. In most cases, the sensitivity will decrease over one to two weeks. Until then, avoid those things that cause discomfort.
Advancements in Dental Fillings
New Materials and Techniques
Dentistry is continuously evolving, and so are the materials and techniques used for fillings. Recent advancements include more aesthetically pleasing and durable composite resin materials and techniques that preserve more of the natural tooth.
Glass Ionomer Fillings
Glass ionomer fillings are a newer type of material that releases fluoride, which can help protect the tooth from further decay. However, these fillings aren’t as durable as other types and are more susceptible to wear and prone to fracture.
Choosing the Right Filling for You
Factors to Consider
The choice of material depends on the extent of the repair needed, whether you have allergies to certain materials, the location of the filling, and the cost. Your dentist will be able to advise you on the best type of filling for your particular case.
