Fillings are a type of dental care that has existed in some form for thousands of years. Cavities in the teeth must be filled in order to keep them from getting larger and spreading decay. Ancient skeletal remains have been found with the cavities filled with beeswax. Today, dentists and their patients have more choices of materials to fill cavities. The fillings most commonly used are made with resin-based composite or metal amalgam, or silver. There are advantages and disadvantages to both types.
What Is A Dental Filling?
They are a common and effective way to treat tooth decay or damage. The procedure is typically quick and minimally uncomfortable, especially with the use of local anesthesia. By addressing issues early and following proper oral hygiene, patients can maintain these dental appliances and overall oral health for years to come.
Metal amalgam fillings
These have been used for over 150 years. According to the National Dental Association, dental amalgam is an alloy. It is a combination of several metals, including silver, copper, tin and mercury. It is held in place by the shape of the cavity.
Advantages of metal amalgam fillings:
- They are strong and durable. They are more resistant to decay around the edges and are less inclined to break.
- These fillings are useful when working in difficult to reach areas of the mouth.
- It is the most economical type of filling material.
Disadvantages of metal amalgam fillings:
- They are limited by size and can be a problem if the cavity is too small to establish the necessary hold and strength.
- These type tend to shrink and expand, which may lead to tooth breakage or stress fractures.
- Many patients do not like the look of silver on their teeth. Over time, it may tarnish, leaving the tooth darker.
Composite fillings
Composite optioins have been used for approximately 40 years. They are made of a plastic resin that is soft in the beginning, but cures to full strength after it is exposed to the blue range on a light spectrum.
The Advantages of Composite Resin Fillings:
- These work well on small to medium sized cavities.
- Not as much of the tooth structure is removed, so there is less drilling.
- People like the way they look because they can match your natural tooth color. It is particularly suited for teeth that are visible.
- They bond to the tooth well, which reduces the chance of breakage.
- In the event of damage, they can be repaired.
The Disadvantages of Composite Resin Fillings:
- These are softer and may wear out more quickly than metal options, particularly if you grind your teeth.
- Their placement is a little more labor intensive and you may have some tooth sensitivity for a short time after the procedure.
- Although they look more natural, they can be stained if you regularly consume tea, coffee, red wine and similar foods. They may also be affected by long term exposure to some forms of alcohol.
- They are more expensive than the amalgam fillings. Your dental insurance company may limit coverage to your visible teeth. They may also have higher co-payments or additional costs for these. Check with your insurance company for details.
