How do dental fillings work?

They restore a tooth damaged by decay back to its normal function and shape by filling the cavity after removing the decayed portion.

Tooth fillings are a common dental procedure used to restore the function and integrity of teeth damaged by decay. The process involves removing decayed tooth material, cleaning the affected area, and then filling the cavity with a suitable material to restore the tooth's original shape and function. This helps to prevent further decay by closing off spaces where bacteria can enter. Fillings can be made from a variety of materials, including amalgam, composite resins, gold, and porcelain, with choices often depending on the location of the filling, the patient's budget, and aesthetic preferences.

Cost Ranges

The cost of dental fillings can vary widely based on the material used and the complexity of the procedure. Here's a general breakdown:
  • Amalgam Fillings: Typically range from $50 to $150 per tooth.
  • Composite Resin Fillings: Can range from $90 to $250 per tooth.
  • Gold Fillings: Usually cost between $250 and $450 per tooth.
  • Porcelain Fillings: These can range from $300 to $500 per tooth.

Local Tips

  • Insurance: Many dental insurance plans cover the cost of standard fillings, especially if they are required for dental health rather than cosmetic reasons. Check with your provider to understand your coverage.
  • Choosing a Dentist: Consider dentists who specialize in restorative dentistry for the best results in complex cases.
  • Preventive Care: Regular check-ups and cleanings can help prevent cavities from forming, potentially saving on the need for fillings.

FAQs

How long do fillings last?
The longevity of a filling depends on the material used. Amalgam fillings can last 10-15 years, while composite resins last around 5-7 years. Regular dental check-ups are essential for monitoring the condition of fillings.
Do fillings hurt?
The procedure is typically performed under local anesthesia, so you should not feel pain during the filling. However, some sensitivity after the procedure is normal and should subside within a few days.
Can cavities under a filling be fixed?
Yes, if decay occurs under a filling, your dentist will need to remove the old filling, clean out the decay, and place a new filling.
