Dental fillings help restore teeth affected by decay. They fill spaces left after removing damaged parts of a tooth. This treatment prevents further decay and helps the tooth function normally.
Dentists use fillings to fix small or moderate cavities. They choose materials that bond well with tooth surfaces. Fillings can last for years if patients maintain good oral hygiene.
What Are Dental Fillings?
Dental fillings are substances dentists use to repair holes in teeth. These holes, also known as cavities, form when acid breaks down tooth enamel. Dentists clean the area and fill it to stop decay from spreading.
Fillings also restore the strength of the tooth. A damaged tooth can become sensitive or weak. The filling keeps it stable and allows normal use when chewing or speaking.
Types of Dental Fillings
Different materials serve as fillings. Each has its own benefits and drawbacks. Dentists choose based on location, cost, and patient preference.
Amalgam Fillings
Amalgam fillings consist of a mix of metals such as silver, tin, copper, and mercury. These materials are combined to create a strong and durable substance, making amalgam an ideal choice for restoring molars and other back teeth where the pressure from chewing is greatest. Due to its resilience, amalgam has been a reliable dental solution for decades and is particularly valued in situations where cost-effective, long-lasting restorations are needed.
While amalgam is known for its strength and affordability, some patients prefer tooth-colored materials for cosmetic reasons, especially for visible areas of the mouth. Clinics like Indental Castle Hill offer a variety of restorative options tailored to individual needs, balancing function and aesthetics. Patients can explore alternatives such as composite resin or ceramic fillings, which blend naturally with the surrounding teeth. By discussing material choices with a trusted dental provider, individuals can make informed decisions that suit both their oral health goals and visual preferences.
Composite Fillings
Composite fillings are made of plastic and glass. They match the colour of natural teeth, making them suitable for front teeth.
Composite bonds well with the tooth. It requires less removal of healthy structure during placement. However, composite may wear faster than amalgam, especially under heavy chewing.
Glass Ionomer Fillings
Glass ionomer fillings contain acrylic and a glass powder. Dentists use them for small repairs, especially in children’s teeth.
They release fluoride, which helps prevent further decay. However, they are not as strong as composite or amalgam fillings.
Ceramic Fillings
Ceramic fillings are made from porcelain. They are tooth-coloured and resist stains well. Dentists use them for patients who want a natural look and better durability.
Ceramic fillings cost more than composite and need more than one visit to place. However, they last long and suit people who value appearance and strength.
How Dentists Place Dental Fillings
The process for placing a filling is simple. Dentists follow a clear set of steps to remove decay and seal the tooth.
Step 1: Examining the Tooth
The dentist checks the tooth for signs of decay. They may use an x-ray to see the extent of the damage.
This helps the dentist decide on the right treatment. If the decay is too deep, they may suggest a crown instead of a filling.
Step 2: Numbing the Area
The dentist applies local anaesthetic. This numbs the area around the tooth and prevents discomfort during the procedure.
Numbing helps the patient relax. The dentist can then work without causing pain.
Step 3: Removing the Decay
The dentist uses a drill or laser to remove decayed parts of the tooth. This step is important because it stops decay from spreading further.
They shape the space to hold the filling material. The shape depends on the type of filling used.
Step 4: Placing the Filling
The dentist places the chosen material in the cleaned space. If it’s a composite filling, they apply it in layers and harden each layer with a special light.
After placing the filling, the dentist trims and polishes it. This ensures it fits well with the bite and feels smooth inside the mouth.
Why Dental Fillings Are Necessary
Cavities weaken teeth. If left untreated, they can cause pain, infection, or tooth loss. Fillings prevent these issues by sealing the space and restoring function.
A filled tooth can handle daily use again. It also helps protect nerves and prevents sensitivity.
Fillings also help maintain proper tooth alignment. A damaged or missing tooth may cause surrounding teeth to shift. This can lead to bite problems and more dental issues.
Signs That You May Need a Filling
Some symptoms may suggest a cavity. Recognising these signs early helps avoid major treatment later.
- Tooth sensitivity to hot, cold, or sweet foods
- Sharp pain when biting or chewing
- Visible holes or dark spots on teeth
- Food getting stuck in the same area
- Rough or chipped spots on the surface of a tooth
If you notice any of these signs, you should see a dentist for an examination. Early action can lead to a simpler and quicker solution.
Caring for Fillings After Treatment
Dental fillings require proper care. With the right habits, they can last many years and protect your tooth.
Brushing and Flossing
You should brush twice a day with fluoride toothpaste. Floss once a day to remove food between teeth. These habits help prevent new decay around the filled area.
Use a soft-bristled toothbrush and avoid hard scrubbing. This protects both the filling and the natural tooth.
Regular Dental Check-ups
Visit the dentist every six months. During these visits, they check the condition of your fillings.
Dentists look for cracks, wear, or signs of new decay. They may polish the filling or suggest replacement if needed.
Avoiding Hard Foods
Avoid biting into hard foods such as ice or hard sweets. These can crack or wear down fillings, especially composite ones.
If you grind your teeth, consider using a night guard. Grinding can weaken both natural teeth and fillings over time.
Risks or Problems Related to Dental Fillings
Fillings are safe, but some problems can occur. It helps to know what to watch for.
- Fillings can crack under pressure
- Older fillings may loosen over time
- Sensitivity may continue for a few days after placement
- Rare allergic reactions to the materials used
If a filling becomes loose or falls out, contact your dentist as soon as possible. Leaving it untreated may expose the tooth to more decay or pain.
When Fillings Need Replacement
Over time, fillings may wear out. Chewing, brushing, and exposure to food acids can cause them to break down.
The dentist may suggest a replacement if they notice wear, cracks, or gaps between the filling and the tooth. Delaying replacement may lead to more serious problems.
Fillings typically last between five and fifteen years. The exact lifespan depends on the material used and your oral care habits.
Alternatives to Fillings
In some cases, a filling may not be the best solution. The dentist might suggest other options based on the size or location of the damage.
Dental Crowns
Crowns cover the entire tooth. They are used when decay is too extensive for a filling to work well.
Crowns offer more protection but are more expensive and take longer to place.
Inlays and Onlays
Inlays and onlays are partial restorations made outside the mouth. They fit into or onto the damaged part of the tooth.
They offer a middle option between fillings and crowns in terms of strength and cost.
Summary
Dental fillings are a common and effective way to treat cavities. They stop decay, restore function, and prevent further damage. Dentists use several materials for fillings, each suited to different needs.
The procedure is quick, safe, and usually completed in one visit. Patients who care for their fillings properly can enjoy long-lasting results.
If you notice signs of decay or damage, see a dentist. Acting early can reduce discomfort and protect your oral health. Fillings play a key role in keeping your teeth strong and useful for years to come.
