Silver tooth fillings, also known as amalgam fillings, have been used in dentistry for over a century. While they have been the go-to option for restoring decayed or damaged teeth, they have also been controversial due to their mercury content. In this article, we will explore what silver tooth fillings are made of, their benefits and drawbacks, and alternative options available.
What are Silver Tooth Fillings Made of?
Silver tooth fillings are made of a mixture of metals, including silver, tin, copper, and mercury. The mercury content in the mixture is what gives the material its pliable and malleable properties, making it easy for dentists to shape and fill cavities. The mixture is known as dental amalgam and has been used in dentistry since the 1800s.
1.Benefits of Silver Tooth Fillings
- Durability: Silver tooth fillings are known for their durability and can last up to 10 to 15 years before needing replacement.
- Cost-effective: Compared to other tooth filling options, silver tooth fillings are relatively inexpensive.
- Ease of placement: Silver tooth fillings are easy to place and can be done in one appointment.
- High success rate: Silver tooth fillings have a high success rate and are effective in treating cavities.
2.Drawbacks of Silver Tooth Fillings
- Mercury content: The mercury content in silver tooth fillings has been a concern for many years. Although the amount of mercury in fillings is relatively small, some people worry about its potential effects on their health.
- Appearance: Silver tooth fillings are visible and can be unsightly, particularly when they are placed on front teeth.
- Sensitivity: Some people experience sensitivity to temperature changes after getting silver tooth fillings.
- Weakening of teeth: Silver tooth fillings require the removal of healthy tooth structure, which can weaken the tooth over time and increase the risk of fractures.
3.Alternatives to Silver Tooth Fillings
- Composite fillings: Composite fillings are made of tooth-colored resin materials, making them more aesthetically pleasing than silver tooth fillings. They are also less likely to cause sensitivity or weaken the tooth structure.
- Ceramic fillings: Ceramic fillings are made of porcelain or zirconia materials, making them highly durable and long-lasting. They are also aesthetically pleasing and do not contain any metal.
- Glass ionomer fillings: Glass ionomer fillings are made of a mixture of acrylic and glass materials, making them highly durable and long-lasting. They are also tooth-colored and release fluoride, which helps prevent further decay.
How are Silver Tooth Fillings Placed?
The process of placing silver tooth fillings involves the following steps:
- Preparing the tooth:
The dentist will first remove any decayed or damaged tooth structure using a dental drill. They may also use a local anesthetic to numb the area around the tooth.
- Shaping the tooth:
The dentist will shape the remaining tooth structure to ensure that it is ready to receive the filling. This may involve creating small grooves or channels in the tooth surface to help the filling material adhere more effectively.
- Placing the filling material:
The dentist will then place the silver filling material into the prepared tooth cavity. They will carefully shape the material to match the contours of the tooth and ensure that it fits snugly and securely in place.
- Hardening the filling material:
To harden the filling material and ensure that it stays in place, the dentist will use a special light or chemical that activates the material and causes it to harden.
- Removing excess material:
After the filling material has hardened, the dentist will remove any excess material and polish the surface of the filling to ensure that it is smooth and comfortable.
- Post-treatment care:
After the filling is placed, the dentist will provide the patient with instructions on how to care for the filling and maintain good oral hygiene. The patient may experience some sensitivity or discomfort in the affected tooth for a few days after the filling is placed, but this is normal and usually subsides quickly.
Conclusion
Silver tooth fillings have been a popular choice for restoring decayed or damaged teeth for many years. While they are durable and cost-effective, they also have their drawbacks, including their appearance and mercury content. Alternative options, such as composite, ceramic, and glass ionomer fillings, are available and offer a more aesthetically pleasing and less controversial option. If you have concerns
