Dental fillings are a common dental treatment used to restore the integrity, function, and morphology of missing tooth structure resulting from caries or external trauma. They are also used to repair the damaged areas of teeth caused by tooth decay. In this article, we will explore the types of dental fillings, the procedure for getting a dental filling, and aftercare recommendations.
Types of Dental Fillings
Dental fillings come in various materials, each with its own set of advantages and disadvantages. The choice of material depends on the extent of repair, where the filling is needed, and cost.
- Amalgam Fillings: Known for their durability, amalgam fillings are made from a mixture of metals including silver, mercury, tin, and copper. They are less expensive than other types but are noticeable due to their silver color. Best for fillings in molars where the chewing load is the greatest.
- Composite Resins: These fillings are matched to be the same color as your teeth and thus used where a natural appearance is desired. The ingredients are mixed and placed directly into the cavity, where they harden. They may not be as durable as metal fillings, especially for large cavities.
- Ceramic Fillings: Made of porcelain, ceramic fillings are more resistant to staining than composite resin materials. They are also quite durable. However, they can be as expensive as gold fillings.
- Gold Fillings: Gold inlays are well-tolerated by gum tissues and might last more than 20 years, making them the most durable choice. However, they are the most expensive option and require multiple visits to install.
- Glass Ionomer: This type of filling is made from acrylic and a specific type of glass material. It releases fluoride, which can help protect the tooth from further decay. However, glass ionomer is less durable than other types and is more susceptible to wear and tear.
The Procedure for Getting a Dental Filling
The process of getting a dental filling typically involves the following steps:
- Local Anesthesia: To numb the area around the affected tooth, your dentist will use a local anesthetic.
- Removing Decay: Next, the dentist will cut through the enamel using a drill to remove any decay. After the decay has been removed, they will shape the space to prepare it for the filling.
- Etching: For a bonded filling, your dentist will etch the tooth with an acid gel before placing the filling.
- Resin Application: For certain types of fillings, a resin is applied and hardened with a bright light to bond the filling to the tooth.
- Polishing: Finally, after the filling has been placed, your dentist will polish it to ensure a smooth finish.
Aftercare for Dental Fillings
After getting a dental filling, it’s common to experience sensitivity to cold and hot in the beginning. Here are some aftercare tips:
- Avoid very hot or cold foods if the filled tooth is sensitive.
- Practice good oral hygiene – brushing twice a day, flossing once a day, and rinsing with an antiseptic mouthwash.
- Visit your dentist regularly for cleanings and checkups.
- Avoid chewing hard foods directly on the filling, especially if you have composite resins or glass ionomer fillings.
Dental fillings are a safe and effective way to restore damaged teeth. By understanding the types of fillings available, what the procedure entails, and how to care for your fillings afterward, you can ensure your dental health remains in top condition. Always consult with your dentist to choose the filling material best suited to your needs.
