Dental Filling
Milwaukie, OR
A filling is a small restoration used to cover holes in the teeth caused by decay. Fillings vary in size and material, and their main purpose is to restore the function and shape of a tooth while preventing further damage. Dental caries, also known as cavities, are one of the most common oral health issues. Restorative dentistry treatments like fillings help halt the effects of tooth decay, stopping harmful bacteria from spreading, preserving teeth, and supporting gum health. At Sue Walker Dentistry, we regularly perform fillings, but our most important role is educating and equipping patients to maintain their oral health and prevent future problems.
What Causes Tooth Decay?
Tooth decay can develop in multiple stages, making regular dental visits essential. The most common form of decay is dental caries, or cavities. Cavities are holes in the teeth caused by acids produced by harmful bacteria feeding on sugars and other residues. The outer layer of the tooth, the enamel, protects the inner structures. Daily activities like chewing and talking create microcracks in the enamel, which provide spaces for bacteria and food particles to lodge. Over time, these bacteria produce acids that gradually erode the enamel. Brushing and flossing regularly removes plaque‚ a sticky, acidic film that forms on teeth‚ and prevents bacterial growth. Plaque that is not removed can harden into tartar, which bonds to the enamel and encourages further decay. Left untreated, cavities can lead to tooth sensitivity, discomfort, and more serious dental issues.
Types of Fillings
Several materials are used for dental fillings. The most common are silver-colored amalgam and tooth-colored composite resins. Composite fillings are increasingly popular because they blend in naturally with the teeth and continue to improve in strength and durability. Gold fillings, in use since the 19th century, are highly resistant to corrosion and biocompatible, making them durable for chewing while protecting surrounding teeth. Porcelain fillings are also biocompatible and highly aesthetic, often making teeth appear whiter. Porcelain is strong and long-lasting, with fillings potentially remaining effective for up to 15 years.
Procedure for Repairing a Cavity
To repair a cavity, the dentist first numbs the area around the tooth with a local anesthetic. The decayed material is then removed using a drill or air abrasion device. After all decay has been cleared, the cavity is cleaned of debris and bacteria to prepare for the filling. Finally, the filling is placed, shaped, and polished to restore the tooth’s function and appearance. Cavities can lead to larger complications if left untreated, but at Sue Walker Dentistry, fillings are part of our everyday practice and your treatment is our priority.
