Fillings are one of the most common treatments in dentistry. They are used to restore a tooth that has been damaged by decay. While fillings help repair cavities and protect teeth from further damage, they do have some disadvantages. It is important to understand these drawbacks so that you can make an informed decision when it comes to your dental care.
In this article, we will explore the disadvantages of fillings, their impact on your dental health, and provide insights into alternatives. This will help you better understand your options and make the best choice for your teeth.
Types of Fillings
Before diving into the disadvantages of fillings, it’s important to understand the types of fillings commonly used in dentistry. Fillings can be made from various materials, each with its pros and cons. The most common types include:
Silver Fillings (Amalgam)
Silver fillings, also known as amalgam fillings, are a mixture of metals, including silver, mercury, tin, and copper. These fillings are strong and durable, making them ideal for restoring teeth that undergo heavy chewing pressure.
Tooth-Colored Fillings (Composite)
Tooth-colored fillings, or composite fillings, are made from a mixture of resins and glass. These fillings are designed to blend with the natural color of your teeth, making them a popular choice for visible teeth.
Gold Fillings
Gold fillings are made of gold alloy and are known for their durability and strength. They are more expensive than other types of fillings but can last for many years.
Ceramic Fillings
Ceramic fillings are made from porcelain and are also tooth-colored. These fillings are resistant to staining but can be more brittle than other options.
Resin Fillings
Resin fillings are a newer type of filling material that is also tooth-colored. They are often used for small cavities and are less durable than amalgam or gold fillings.
Each type of filling material comes with its own set of advantages and disadvantages. However, regardless of the material used, all fillings have some drawbacks.
Disadvantages of Fillings
Although fillings are essential for treating cavities, they do have some disadvantages that you should be aware of. These include:
1. Sensitivity
After getting a filling, it is not uncommon for the treated tooth to become sensitive. This sensitivity can occur when the tooth is exposed to hot, cold, or sweet foods and drinks. The sensitivity can last for a few days or even weeks, depending on the type of filling and the extent of the procedure.
Why does sensitivity occur?
The sensitivity occurs because the filling material may cause changes in the tooth’s structure, or the tooth’s nerves may be affected during the procedure. The depth of the cavity also plays a role in the amount of sensitivity experienced.
2. Risk of Cracking or Breaking
Some types of fillings, particularly composite or ceramic fillings, may be more prone to cracking or breaking over time. These materials are not as strong as amalgam or gold fillings and may not be able to withstand heavy pressure from chewing.
What causes fillings to crack?
Fillings can crack when exposed to excessive force, such as biting down on hard foods, or due to wear and tear over time. Cracks in the filling can lead to further damage to the tooth and may require a replacement.
3. Fillings Can Wear Down
Over time, fillings can wear down, especially those made from composite or resin materials. The constant pressure from chewing and biting can cause the filling material to degrade, potentially requiring a replacement.
How long do fillings last?
The lifespan of a filling depends on several factors, including the material used, the size of the cavity, and the patient’s oral care habits. Typically, amalgam fillings last between 10 and 15 years, while composite fillings last around 5 to 7 years. Gold fillings can last even longer, but they are expensive.
4. Fillings May Not Match the Color of Your Natural Teeth
While tooth-colored fillings (composite and ceramic) are designed to blend in with the color of your teeth, they may not always match perfectly. This can be particularly noticeable if the filling is placed in a highly visible area, such as the front teeth.
Are there ways to improve the color match?
Yes, your dentist can adjust the shade of the filling to try to match it more closely with your natural teeth. However, some materials may still show slight differences in color, especially over time as the material ages.
5. Fillings May Not Be a Permanent Solution
Fillings are not a permanent fix for a cavity. Over time, they can wear down, crack, or fail. When this happens, the tooth may require further treatment, such as a root canal or even extraction. In some cases, if a filling becomes loose or falls out, it can lead to further decay in the tooth, making it more difficult to restore.
How can I prevent this from happening?
Regular dental check-ups are crucial for monitoring the condition of your fillings and catching any issues early. Proper oral hygiene, including brushing and flossing, can also help extend the lifespan of your fillings.
6. Potential for Allergic Reactions
Some people may experience allergic reactions to certain materials used in fillings, particularly amalgam fillings, which contain mercury. While mercury is generally considered safe in dental amalgam, some individuals may be sensitive to it and experience symptoms like swelling or irritation.
What to do if you have an allergy?
If you suspect an allergic reaction to a filling, it is essential to contact your dentist immediately. In some cases, your dentist may recommend replacing the filling with a material that is better suited to your needs, such as a composite or resin filling.
7. Fillings Can Be Expensive
While some types of fillings, like amalgam, are relatively affordable, others, such as gold or ceramic fillings, can be quite expensive. The cost of a filling depends on the material used, the size of the cavity, and your location. Insurance coverage may not cover the full cost of certain types of fillings, leaving patients with out-of-pocket expenses.
Can you avoid these costs?
Preventive care is key to avoiding the need for fillings in the first place. Regular brushing, flossing, and visits to the dentist can help prevent cavities, reducing the need for fillings altogether.
8. Risk of Infection
If a filling is not properly placed or becomes damaged, it can create an opening for bacteria to enter the tooth. This can lead to further decay or even an infection in the tooth. In some cases, the infection may require additional treatments, such as a root canal.
How can infection be prevented?
Ensuring that the filling is properly placed and maintained is important in reducing the risk of infection. Regular dental visits will allow your dentist to check for any issues with your fillings and treat them before they lead to further problems.
Alternatives to Fillings
While fillings are an effective way to treat cavities, there are alternatives that may be more suitable for certain situations. These alternatives include:
1. Crowns
Crowns are a more extensive treatment for large cavities. They cover the entire tooth and provide extra protection. Crowns can be made from various materials, including porcelain, ceramic, or metal.
2. Inlays and Onlays
Inlays and onlays are similar to fillings but are custom-made in a dental laboratory. They are often used for larger cavities that require more extensive restoration.
3. Dental Implants
For severely damaged teeth that cannot be restored with fillings, dental implants may be an option. Implants are artificial tooth roots that are surgically placed into the jawbone, providing a foundation for a crown or other restoration.
Conclusion
Fillings are a common and effective way to treat cavities and restore teeth. However, they do come with their own set of disadvantages, including sensitivity, cracking, and wear over time. It is essential to discuss your options with your dentist to determine the best course of action for your dental health.
By maintaining good oral hygiene and attending regular dental check-ups, you can help ensure the longevity of your fillings and reduce the need for future treatments. If you have concerns about fillings, be sure to talk to your dentist about the potential risks and alternatives available.
Ultimately, the best way to prevent the need for fillings is through good dental care, including brushing, flossing, and avoiding sugary foods and drinks.
