How to choose the right tooth filling​

When it comes to maintaining a healthy and beautiful smile, one of the essential considerations is choosing the right dental filling. Dental fillings are a common solution for addressing tooth decay, ensuring your teeth remain strong and functional. Keep reading to explore the most prevalent types of dental fillings, discuss their benefits, and key factors to keep in mind when deciding which one is right for you.

What is the most common type of dental filling?
The most prevalent type of dental filling is the silver amalgam filling. These fillings have stood the test of time and have been used in dentistry for well over a century. They are composed of a mixture of metals, including silver, tin, copper, and mercury. This combination of metals creates a filling material that is exceptionally durable and long-lasting.

Silver amalgam fillings are typically used for back teeth, such as molars, where the chewing forces are the greatest. Their strength makes them an ideal choice for these areas. While silver amalgam fillings have been a staple in dental care, they have faced some controversy due to their mercury content. However, it's important to note that the American Dental Association considers silver amalgam fillings safe for most dental patients.

Why do dentists still use silver fillings?
Dentists continue to use silver amalgam fillings for several compelling reasons:

• Durability: Silver amalgam fillings are exceptionally durable and can withstand the forces of chewing and grinding in the back teeth, where these fillings are typically used.
• Cost-effective: Silver fillings are more affordable compared to tooth-coloured composite fillings and gold fillings, making them a cost-effective option for patients and healthcare systems.
• Efficiency: They are relatively quick and straightforward to place, reducing chair time for patients and making dental procedures more efficient.

Which filling is the most expensive?

The cost of dental fillings can vary widely depending on several factors, including the material used and the location of the tooth. In general, silver amalgam fillings are more affordable than tooth-coloured composite fillings. Gold fillings, while less common, tend to be the most expensive option due to the cost of the precious metal itself and the skill required to place them.

It's essential to check with your dental insurance provider, as many plans cover a portion of the cost of dental fillings. This can significantly impact the out-of-pocket expenses for patients.

How many times can a tooth be filled?
In general, a tooth can be filled multiple times if necessary. However, each time a filling is replaced, some of the tooth's natural structure is removed. Over time, this can weaken the tooth. Dentists strive to preserve as much of the natural tooth structure as possible, but in cases of extensive decay or damage, multiple fillings may be required.

It's crucial to consult with your dentist to determine the most appropriate course of action for a tooth with multiple fillings. They can assess the tooth's condition and discuss options for treatment and restoration.

What happens when fillings get old?
Over time, dental fillings, regardless of their type, can experience wear and tear. Here's what can happen as fillings age:

• Wear and erosion: The constant pressure from chewing, biting, and grinding can cause fillings to wear down and become less effective at sealing the tooth. This can lead to gaps or openings around the filling, allowing bacteria to penetrate and cause further decay.
• Cracks and fractures: Fillings can develop small cracks or fractures due to the stresses they endure while supporting your tooth's structure. These cracks can worsen over time and compromise the filling's integrity.
• Leakage: As fillings age, they may lose their tight seal against the tooth. This can allow food particles and bacteria to infiltrate the gap between the filling and the tooth, leading to new decay or tooth sensitivity.
• Discoloration: Silver amalgam fillings can darken or become discolored over time. This can affect the appearance of your smile, especially if the filling is in a visible area.
• Tooth Sensitivity: As fillings deteriorate, you might experience increased tooth sensitivity to hot, cold, sweet, or acidic foods and beverages.

How often do old fillings need to be replaced?
The lifespan of a dental filling varies depending on several factors, including the type of filling material, the location of the filling in your mouth, and your oral hygiene practices. Regular dental check-ups are crucial for monitoring the condition of your fillings. Your dentist will assess their integrity and recommend replacement if necessary to prevent further dental problems. With that being said, here's a general guideline on how often old fillings need to be replaced:

• Silver amalgam fillings: These fillings can last anywhere from 10 to 15 years, and sometimes even longer. However, as they age, they may need maintenance or replacement due to wear and tear.
• Composite (tooth-coloured) fillings: Composite fillings have become more durable in recent years and can last 7 to 10 years or more with proper care.
• Gold fillings: Gold fillings are known for their longevity and can last 15 years or more. They are exceptionally durable and resistant to wear.

Should I replace silver fillings with white?
Whether or not to replace silver fillings with white (composite) fillings depends on several factors, including your oral health, the condition of the existing fillings, and your aesthetic preferences. Here are some considerations:

• Oral health: If your silver fillings are still in good condition and effectively sealing your teeth, there may be no immediate need to replace them.
• Aesthetics: Some people choose to replace silver fillings with tooth-coloured composite fillings for cosmetic reasons, especially if the silver fillings are visible when they smile.
• New decay or damage: If your silver fillings are failing, leaking, or causing problems, your dentist may recommend replacement to prevent further dental issues.
• Cost: Replacing fillings can be more expensive than maintaining existing ones. Discuss the cost and benefits with your dentist before making a decision.

Which fillings last longest?
When it comes to dental fillings, durability is a key consideration. The longevity of a filling can vary based on its material and how well it's maintained. Exploring the different types of fillings and their expected lifespans can help you make informed decisions about your dental care.

• Gold fillings: Gold fillings are renowned for their durability and longevity. They can last 15 to 30 years or even longer with proper care.
• Porcelain fillings (Inlays/Onlays): Porcelain fillings, also known as inlays and onlays, are highly durable and can last 15 to 20 years.
• Composite fillings: Composite fillings, made from a mixture of resin and powdered glass, can last 7 to 10 years. Their longevity depends on factors like tooth location and how well they are cared for.
• Silver (Amalgam) fillings: Amalgam fillings also have good durability and can last 10 to 15 years or more.
• Ceramic fillings: Ceramic fillings, like porcelain, are known for their longevity and can last 15 to 20 years.

Selecting the right dental filling is a decision that should be made in consultation with your dentist. Your oral health, the condition of your existing fillings, and your aesthetic preferences all play a role in determining the best choice for you. Whether it's silver amalgam, tooth-colored composite, or another material, the goal is to preserve your smile's health and beauty.
