Tooth decay is a common dental issue that affects people of all ages. When cavities occur, prompt dental intervention becomes necessary to prevent further damage and restore the tooth’s health. This article aims to provide a comprehensive guide to tooth restorations by answering common questions you may have about the process.

What causes tooth decay?

Tooth decay occurs when bacteria in your mouth produce acid that erodes the tooth enamel. This can happen due to poor oral hygiene, a sugar-rich diet, or certain medical conditions that weaken the enamel. Factors such as genetics and lifestyle habits can also play a role in tooth decay.

How can I tell if I have a cavity?

Common signs of cavities include toothaches, sensitivity to hot or cold temperatures, visible pits or holes on the tooth’s surface, or dark spots. Regular dental check-ups are essential to detect cavities in their early stages before they become more painful or progress further.

How are cavities filled?

The process of filling cavities involves several steps. First, the dentist will numb the area around the tooth using local anesthesia to ensure a painless procedure. Then, the decayed part of the tooth is carefully removed, leaving behind a clean preparation. Afterward, a filling material is used to restore the tooth’s structure and prevent further decay. The most common types of fillings are composite resin, tooth-colored fillings, amalgam fillings, and gold or porcelain fillings.

What is a composite resin filling?

Composite resin fillings are a popular option due to their tooth-like appearance and potential for a more natural-looking smile. This type of filling material is made from a mixture of plastic and glass. It bonds directly to the tooth and can withstand moderate pressure from chewing. However, composite fillings may not be ideal for larger cavities or areas that experience excessive biting force.

What are amalgam fillings?

Amalgam fillings, commonly known as silver fillings, are made by mixing several metals, including silver, mercury, tin, and copper. They have been used for decades and are favored for their durability and affordability. Amalgam fillings are silver in color, which makes them more noticeable compared to other filling materials. However, they are strong and can withstand the constant pressure of chewing in the back teeth.

How long do tooth fillings last?

The lifespan of a filling depends on various factors, including the type of filling material used, its location in the mouth, the extent of tooth decay, and oral hygiene practices. On average, tooth-colored fillings usually last between 5 to 7 years, while silver amalgam fillings can last up to 15 years or more. However, it is important to remember that regular dental check-ups and good oral care habits are crucial for maintaining the longevity of any filling.

Tooth restorations play a vital role in treating cavities and preserving oral health. Understanding the causes of tooth decay and the process of filling cavities can help you make informed decisions about your dental care. Remember to consult your dentist regularly and practice good oral hygiene to minimize the risk of developing cavities and ensure the longevity of your tooth restorations.
