Tooth Fillings: Materials, Types, Procedure, Cost and More

Tooth fillings are a common solution in dentistry for restoring teeth damaged by decay back to their normal functionality and shape. When a dentist performs a filling, they first remove the decayed tooth material, clean the affected area, and then fill the cavity with a filling material. Different types of filling materials include amalgam, porcelain, composite resin, and gold. Each material type carries its own benefits and costs, which can influence the choice made. Care after the procedure is critical for the longevity of the filling and overall oral health. This article aims to provide a comprehensive understanding of tooth fillings, materials used, types, costs, aftercare, and frequently asked questions.

Materials Used for Tooth Fillings

There are several materials used for tooth fillings, each with their unique attributes:

  1. Amalgam: This is a blend of mercury, silver, tin, and copper. Amalgam has been used for over 150 years by hundreds of millions of patients around the world. It is durable, inexpensive, and resistant to wear, making it great for large cavities in back teeth. However, it is noticeable due to its dark color and contains mercury.
  2. Composite Resins: These are preferred for their aesthetic appeal as they match the natural tooth color. They are made of a mixture of glass or quartz filler and can be used for both small and large cavities. They provide good durability for small- to mid-size fillings that need to withstand moderate pressure.
  3. Gold: Gold fillings, or inlays, are composed of an alloy of gold, copper, and other metals. This type of filling is well-tolerated by gum tissues and may last more than 20 years. However, it is the most expensive choice and requires multiple dental visits to place.
  4. Porcelain: This material is usually called a ceramic filling. Porcelain is resistant to staining and can be matched to the color of your natural teeth. However, it is as expensive as gold.

Types of Tooth Fillings

  1. Direct Fillings: These fillings, known as direct fillings, are carefully placed directly into the cavity by a dental professional. This efficient procedure typically takes just one visit, saving you time and ensuring a quick and convenient solution for your dental needs.
  2. Indirect Fillings: To complete these procedures, it typically requires two visits. During the first visit, the dentist will carefully prepare the tooth and take a precise mold to ensure an accurate fit. Then, on the second visit, the filling will be expertly placed, ensuring a comfortable and long-lasting result. Rest assured, this comprehensive approach guarantees the best possible outcome for your dental health.
  3. Temporary Fillings: These additional visits are necessary when the procedure calls for further attention or in situations where a temporary tooth issue arises, demanding prompt resolution. By addressing these specific needs, dental professionals ensure comprehensive care and optimal oral health outcomes for their patients.

Procedure for Tooth Fillings

The procedure for fillings is typically straightforward and relatively painless. It involves:

  1. Numbing – The dentist will usually use an anesthetic to numb the area around the affected tooth.
  2. Removing decay – Using a drill or laser, the dentist will remove the decayed tooth material.
  3. Etching – If composite resin is used, the dentist will apply an acid gel to roughen up the tooth surface to help the filling bond securely.
  4. Applying bonding agent – For composite fillings, a liquid bonding agent is applied before adding the filling.
  5. Adding and shaping the filling – The dentist will then add and shape the filling material to fit the cavity.
  6. Curing – For composite fillings, a special light is used to harden the material and bond it to the tooth.
  7. Trimming and polishing – Once hardened, excess material is trimmed and polished for a smooth finish.
  8. Checking your bite – After completing the filling, the dentist will check your bite to ensure it is comfortable and does not interfere with your other teeth.

Cost of Tooth Fillings

The cost of fillings varies based on several factors such as the material used, size of the cavity, location, and dental insurance coverage. On average, traditional amalgam fillings cost between $75-$200 per tooth while composite fillings range from $150-$250 per tooth. Gold and porcelain fillings can cost significantly more, with prices ranging from $600-$4,500 per tooth. Before proceeding with a filling, it is best to consult your dentist for an accurate estimate based on your individual needs.

Aftercare for Tooth Fillings

To ensure the longevity of your filling, proper care is necessary. This includes:

  • Brushing your teeth twice a day with fluoride toothpaste.
  • Flossing daily to remove food particles and plaque from between the teeth.
  • Eating a healthy diet, and limiting sugary foods and drinks.
  • Avoid sticky foods that can dislodge or damage the filling.

If you experience any discomfort or pain after getting a filling, contact your dentist for a follow-up visit.
