Dental Fillings: The Types, Complete Process, and Aftercare


Dental fillings are a standard procedure to restore teeth’ functionality and appearance damaged by decay, fractures, or wear. They are essential to continuing good oral health, as they prevent further decay and damage to the tooth structure. 

This blog section will explore the different types of dental fillings, the complete process of getting a dental filling, and the proper aftercare to ensure long-lasting results.

Types of Dental Fillings

1. Amalgam Fillings

These fillings are made of silver, tin, copper, and mercury. Amalgam fillings are durable, long-lasting, and relatively inexpensive, making them popular for filling large cavities in the back teeth. However, some individuals may be worried about the mercury in these fillings and their appearance, as they do not suit the color of natural teeth.

2. Composite Fillings 

Composite fillings are formed from a combination of plastic and glass particles, allowing them to match the natural tooth’s color closely. They are famous for filling small to medium-sized cavities and are more aesthetically pleasing than amalgam fillings. However, composite fillings are less durable and may not last as long as other materials.

3. Ceramic Fillings 

Ceramic fillings, usually made of porcelain, offer excellent aesthetics as they can be closely matched to the color of the natural tooth. They are also highly resistant to stains and wear. However, ceramic fillings can be more expensive than others and may require a more complex installation procedure.

4. Glass Ionomer Fillings 

Glass ionomer fillings are produced from a mixture of acrylic and glass particles that release fluoride, which helps prevent further decay. These fillings are often used for filling cavities near the gum line or in children’s teeth. Glass ionomer fillings are less durable than other materials and may require to be replaced more frequently.

The Complete Process of Getting a Dental Filling

1. Consultation and Diagnosis 

During this appointment, your dentist will go through your teeth and may use dental X-rays to determine the extent of the decay. They will then recommend the best filling material for your specific needs.

2. Local Anesthesia

Before the filling begins, your dentist will administer a local anesthetic to numb the area around your tooth. This will minimize any discomfort during the procedure.

3. Removal of Decay

Your dentist will use specialized dental tools, such as a dental drill or laser, to remove the decayed portion of the tooth. They will carefully remove all of the decay, ensuring the remaining tooth structure is healthy and bacteria-free.

4. Preparation for the Filling

Your dentist will prepare your tooth for the filling material once the decay has been removed. This may involve etching the tooth’s surface with an acid gel to help the filling material bond more effectively or applying a bonding agent.

5. Placement of the Filling

The filling material is set into the prepared cavity. Depending on the filling material, your dentist may need to apply it in layers and use a special light to treat or harden the fabric between each layer.

6. Finishing and Polishing 

Once the filling has been placed, your dentist will shape the material to match the natural contours of your tooth. They will then polish the filling to ensure a smooth surface and proper bite alignment.

Aftercare for Dental Fillings

Proper aftercare is essential to ensure your dental fillings’ longevity and maintain good oral health. Following these guidelines can help keep your fillings in good condition:

1. Maintain Great Oral Hygiene

Brushing your teeth at least twice daily and flossing daily will help prevent plaque buildup and further decay. Be sure to use toothpaste having fluoride to strengthen the tooth enamel.

2. Avoid Hard or Sticky Foods

Chewing on hard or sticky foods can cause your fillings to crack or dislodge. To protect your fillings, avoid these foods, especially in the days following your dental filling appointment.

3. Limit Sugary Foods and Drinks

Consuming excessive sugar can contribute to tooth decay and damage your fillings. Limit your sugary foods and beverages intake, and opt for healthier alternatives whenever possible.

4. Use a Mouthguard

If you engage in sports or have a habit of grinding your teeth at night, consider using a mouthguard to preserve your teeth and fillings from damage.

5. Regular Dental Checkups

Visit your dentist for regular checkups and cleanings to ensure your fillings are in good condition and to catch any potential issues early.


Proper aftercare following a dental filling is crucial to protect the success and longevity of the treatment. Maintaining good oral hygiene, being cautious with your diet, avoiding harmful habits, and attending regular dental check-ups can help protect your filled tooth and overall oral health.  Following these tips and considering preventive measures like sealants, you can keep your teeth healthy and strong for years.
