How Do Fillings Work? A Complete Guide to Dental Fillings

Dental fillings are a common solution for cavities and tooth decay, helping to restore and protect your teeth. But how do fillings work? This guide will walk you through the dental filling procedure, types of fillings, and what to expect before, during, and after the process.

Understanding the Dental Filling Procedure

A dental filling procedure is used to repair damage caused by cavities or tooth decay. Here’s what happens step by step:

1. Diagnosis – Your dentist will examine your tooth and may use X-rays to assess the extent of decay.
2. Numbing the Area – A local anesthetic is applied to ensure a pain-free experience.
3. Removing Decay – The decayed portion of the tooth is carefully removed to prevent further damage.
4. Filling Placement – The selected filling material is placed in the cleaned cavity.
5. Shaping and Polishing – The filling is shaped to match your natural bite and polished for a smooth finish.
6. Final Check – Your dentist will ensure the filling is secure and comfortable, making any necessary adjustments.

4 Types of Fillings: Which One is Best for You?

Choosing the right filling material is essential for durability and aesthetics. The 4 types of fillings commonly used in dentistry include:

1. Amalgam Fillings

Made of a mixture of silver, tin, copper, and mercury, these are strong and cost-effective but noticeable due to their dark color. They have been used for decades due to their durability.

2. Composite Fillings

Tooth-colored composite resin is a popular choice for its natural appearance and strong bonding to teeth. It blends well with the tooth, making it ideal for visible areas.

3. Ceramic Fillings

Made from porcelain, these fillings are durable, stain-resistant, and aesthetically pleasing but can be more expensive. They are highly resistant to wear and are biocompatible.

4. Glass Ionomer Fillings

These fillings release fluoride, helping prevent further decay. They are ideal for children’s teeth but may not last as long as other materials. They bond well to the tooth but can wear down faster than other options.

Tooth Filling: Does It Hurt?

Many people wonder, “Tooth filling: does it hurt?” The short answer is no—thanks to modern dentistry techniques and local anesthetic, the procedure is generally painless. You may feel mild sensitivity after the filling, but this subsides within a few days.

To minimize discomfort:

• Avoid hot or cold foods immediately after the procedure
• Use desensitizing toothpaste if sensitivity persists
• Follow your dentist’s aftercare instructions carefully
• Take over-the-counter pain relievers if necessary

What to Expect During the Tooth Filling Process? 

The tooth filling process typically includes:

1. Pre-treatment X-ray
2. Numbing of the area
3. Removal of decay
4. Placement of the filling material
5. Shaping and polishing
6. Final bite adjustment

Your dentist may show you before-and-after images of your tooth to illustrate the effectiveness of the procedure.

How to Care for Your Filling After the Procedure?

• Avoid Hard or Sticky Foods – Give your filling time to settle by avoiding tough foods that could dislodge or damage it.
  
  
• Manage Sensitivity – Mild sensitivity to hot and cold foods is normal and should subside within a few days. Desensitizing toothpaste can help.
  
  
• Maintain Good Oral Hygiene – Brush and floss regularly to prevent further decay around the filling. Use a fluoride toothpaste for added protection.
  
  
• Watch for Signs of Wear or Damage – If you experience pain, sharp edges, or notice any cracks in the filling, schedule a check-up.
  
  
• Regular Dental Visits – Routine exams help ensure your filling remains intact and catch any potential issues early.

How Long Do Fillings Last?

The lifespan of a filling depends on the material used, oral hygiene, and eating habits:

• Amalgam fillings: 10-15 years
• Composite fillings: 5-10 years
• Ceramic fillings: 15+ years
• Glass ionomer fillings: 5-7 years

To extend the lifespan of your fillings:

• Brush and floss daily
• Avoid chewing hard foods
• Schedule regular dental check-ups
• Use fluoride toothpaste to strengthen enamel

Permanent Tooth Filling at Home: Is It Possible?

While some permanent tooth filling at home kits are available, they are only temporary solutions. A professional dentist should always perform fillings to ensure the cavity is completely cleaned and sealed properly. DIY fillings can lead to infection and further decay if not done correctly.

Temporary at-home fillings may help in emergencies but should be replaced by a professional filling as soon as possible.

Best Tooth Filling Material: Which One Should You Choose?

The best tooth filling material depends on your needs:

• For front teeth: Composite or ceramic for aesthetic appeal
• For back teeth: Amalgam for durability
• For children: Glass ionomer for fluoride release
• For patients with metal allergies: Ceramic or composite fillings

Your dentist will recommend the most suitable option based on your oral health and personal preference.
