Amalgam fillings, also called silver fillings, have been used to treat cavities for many years. They are a trusted option because they are durable, affordable, and effective. However, there are ongoing discussions about their safety and whether other options might be better. This guide will explain everything you need to know about amalgam fillings, so you can make the best decision for your dental health.
Why do you need a filling?
A dental filling is necessary when a cavity, or decay, forms in a tooth due to bacteria in the mouth breaking down sugars and acids. Over time, this decay can create a hole or cavity in the tooth, which can lead to pain, infection, and further damage if left untreated. A filling helps to restore the tooth’s structure and prevent the decay from spreading. By filling the cavity, the dentist protects the tooth from additional damage, relieves pain, and restores normal function, allowing you to chew and speak comfortably.
Additionally, fillings prevent harmful bacteria from entering the cavity and causing an infection, which could lead to more serious dental issues like abscesses or tooth loss. Regular dental check-ups are essential in catching cavities early before they become more severe and require complex treatments.
What is an amalgam filling?
Amalgam fillings are made from a blend of metals, including mercury, silver, tin, and copper. Dentists often use these fillings for cavities in the back teeth because they can handle a lot of pressure from chewing.
Key benefits of amalgam fillings:
- Durability: These fillings can last for 10-15 years or even longer.
- Cost-effective: They are generally more affordable than composite or gold fillings.
- Quick placement: The material sets quickly, so the procedure doesn’t take much time.
What is the difference between amalgam or composite filling?
When choosing between amalgam and composite fillings, it’s important to understand how they differ.
Amalgam fillings:
- Material: Made from a mixture of metals.
- Color: Silver or grey, making them easy to spot against natural teeth.
- Durability: Very strong and ideal for teeth that handle a lot of chewing.
- Cost: Less expensive than other options.
Composite fillings:
- Material: Made from tooth-coloured resin.
- Aesthetic appeal: Blends naturally with the surrounding teeth.
- Durability: Works well for small to medium cavities but may not last as long as amalgam.
- Cost: More expensive than amalgam fillings.
Should you get an amalgam filling or composite filling?
Your choice will depend on several factors, like the size and location of the cavity, your budget, and how important appearance is to you. Amalgam fillings are a good option if you need something durable and affordable. For front teeth or visible areas, composite fillings are often a better choice.
What are other alternatives to amalgam fillings?
If you’re looking for alternatives to amalgam fillings, here are some options to consider:
Gold fillings:
- Pros: Extremely durable and long-lasting.
- Cons: Expensive and noticeable due to their colour.
Porcelain fillings:
- Pros: Look natural and resist staining.
- Cons: Cost more than amalgam and composite fillings.
Is an invisible filling better than an amalgam filling?
Invisible fillings, such as those made from composite or porcelain, are preferred for their aesthetic appeal, especially in visible areas. They blend seamlessly with your natural teeth, making them an ideal choice for anyone seeking a more natural-looking solution.
At WeSmile Dental Care, we have an aesthetic dentistry specialist who can ensure that your invisible fillings are expertly crafted to match your tooth colour, creating a flawless and discreet restoration. While invisible fillings may not be as durable as amalgam fillings in teeth that experience heavy chewing, their superior cosmetic benefits make them the top choice for many patients.
Why does maintaining your amalgam or other fillings well matter?
Once a filling is placed, it’s important to maintain it properly to ensure its longevity and the continued health of your tooth. Here are some key benefits of keeping your fillings in good condition:
- Prevention of Further Decay: Well-maintained fillings help protect your tooth from further decay. As fillings wear down or become damaged, they may allow bacteria to seep in and cause new cavities, leading to the need for additional dental work.
- Avoiding Pain and Sensitivity: A damaged filling can expose the inner layers of the tooth, leading to increased sensitivity and pain, especially when eating or drinking. By maintaining your fillings, you can prevent this discomfort and ensure the health of your tooth.
- Preserving Tooth Structure: Fillings help maintain the tooth’s natural shape and structure. Regular care, including avoiding excessive pressure on the filled tooth (like biting on hard objects), can prevent the filling from breaking or loosening.
- Aesthetic Appeal: If you have cosmetic fillings, maintaining them ensures they continue to blend seamlessly with your natural teeth. Damaged or worn-out fillings may become noticeable, affecting your smile’s appearance.
- Cost Savings: Proper maintenance of your fillings reduces the likelihood of needing more expensive dental procedures, such as root canals or extractions, by preventing further damage to the tooth.
- Longer Lasting Results: Well-maintained fillings can last many years, providing durable protection and function to your teeth. Regular check-ups allow your dentist to assess the condition of your fillings and replace them if needed before they cause larger issues.
How to care for your amalgam fillings
To keep your fillings in the best condition, practice good oral hygiene by brushing and flossing regularly, visiting your dentist for routine check-ups, and avoiding habits like teeth grinding or chewing on hard objects. If you notice any discomfort or signs that your filling may be compromised, such as cracks or gaps, consult your dentist promptly to prevent further issues.
What are the main concerns of amalgam fillings?
While health experts agree that amalgam fillings are safe, some people have concerns about their mercury content. Mercury in amalgam fillings is combined with other metals, making it stable and safe for most people. However, some patients choose alternatives due to:
- Appearance: The silver color stands out.
- Potential allergies: Rare cases of metal sensitivity.
- Environmental concerns: Disposal of mercury-containing materials can impact the environment.
Should I remove an amalgam filling?
You might consider replacing an amalgam filling if:
- It is damaged, cracked, or worn out.
- You have an allergy or sensitivity to the material.
- You prefer a more natural-looking option for visible teeth.
Important note:
Always have amalgam fillings removed by a professional dentist. Removing amalgam fillings requires careful handling to minimise the release of mercury vapour, which can occur during the process. A professional dentist will use specialised tools and techniques, such as rubber dams and high-volume suction, to ensure that any potential mercury exposure is kept to a minimum.
Additionally, the dentist will take precautions to protect your health, such as using protective gear like masks and eyewear, and ensuring the area is well-ventilated. It is crucial to avoid attempting to remove amalgam fillings on your own or seeking unqualified practitioners, as improper removal can increase the risk of mercury exposure. If you are considering replacing your amalgam fillings, consult with a skilled dentist to ensure a safe and effective procedure.
What are potential side effects of pulling teeth with amalgam fillings?
When a tooth with an amalgam filling is extracted, small amounts of mercury vapour might be released. Dentists take extra precautions, such as using rubber dams and suction tools, to reduce exposure. Possible side effects include:
- Temporary sensitivity in the affected area.
- Minimal risk of mercury exposure if proper procedures aren’t followed.
