Dental cavities are caused by the erosion of tooth enamel, the hard outer layer of your teeth, by acids produced by bacteria in your mouth. If left untreated, cavities can lead to pain, infection, and even tooth loss. Fortunately, dentists have a variety of ways to fill cavities and restore your teeth to health.
The most common way to fill a cavity is with a composite resin filling. Composite fillings are made of a plastic and glass mixture that is matched to the color of your teeth. They are strong, durable, and can be used to fill both small and large cavities. Other types of fillings include amalgam fillings, which are made of a mixture of metals, and glass ionomer fillings, which are made of a glass and acrylic mixture. Your dentist will recommend the best type of filling for your individual needs.
Before filling a cavity, your dentist will first numb the area around the tooth. They will then remove the decayed portion of the tooth and clean the area. The filling material is then placed in the cavity and shaped to match the contours of your tooth. Once the filling is in place, your dentist will harden it with a special light. The entire process usually takes about 30 minutes to an hour.

Preparation
Before filling a cavity, your dentist will first numb the area around the tooth and remove the decayed portion of the tooth. This step is crucial because it helps to ensure that the filling is successful and that the patient experiences minimal discomfort during the procedure.
If the area around the tooth is not properly numbed, the patient may experience pain during the filling process. This can make it difficult for the dentist to complete the filling and can also lead to anxiety and fear of future dental procedures.
Removing the decayed portion of the tooth is also important because it helps to prevent the cavity from spreading and causing further damage to the tooth. If the decayed portion of the tooth is not removed, the filling may not be able to properly seal the tooth and prevent bacteria from entering.
By following these steps, dentists can help to ensure that fillings are successful and that patients experience minimal discomfort during the procedure.
Materials
Composite resin is the most popular choice for fillings because it is strong, durable, and can be matched to the color of your teeth. This makes it a good option for both front and back teeth.
-
Advantages of composite resin fillings:
- Strong and durable
- Can be matched to the color of your teeth
- Bonds to the tooth, which makes it less likely to fall out
-
Disadvantages of composite resin fillings:
- More expensive than amalgam fillings
- Can take longer to place than amalgam fillings
In addition to composite resin, there are other types of filling materials that dentists may use, including amalgam, glass ionomer, and gold.
Placement
The placement of the filling material is a crucial step in the process of filling a cavity. It is important to ensure that the filling is placed correctly in order to prevent further damage to the tooth and to ensure that the filling lasts for as long as possible.
-
Proper placement of the filling material helps to:
- Prevent the cavity from spreading
- Protect the tooth from further damage
- Ensure that the filling lasts for as long as possible
-
If the filling material is not placed correctly, it can:
- Fall out
- Cause pain
- Lead to further damage to the tooth
Dentists use a variety of techniques to ensure that the filling material is placed correctly. These techniques include:
- Using a dental dam to isolate the tooth and keep it dry
- Using a matrix band to hold the filling material in place
- Using a curing light to harden the filling material
By following these techniques, dentists can help to ensure that fillings are placed correctly and that they last for as long as possible.
Hardening
Once the filling material has been placed in the cavity and shaped to match the contours of the tooth, the dentist will use a special light to harden it. This process is called curing.
Curing is an important step in the filling process because it helps to ensure that the filling is strong and durable. Without curing, the filling material would be soft and weak, and it would not be able to protect the tooth from further damage.
The type of light that is used to cure the filling material will depend on the type of material that is being used. Composite resin fillings are cured with a visible light, while amalgam fillings are cured with a chemical reaction.
Once the filling material has been cured, it will be hard and strong, and it will be able to protect the tooth from further damage.
Conclusion
Hardening the filling material is an important step in the process of filling a cavity. This process helps to ensure that the filling is strong and durable, and that it will be able to protect the tooth from further damage.
Finishing
The final step in the process of filling a cavity is to polish the filling to make it smooth and comfortable. This step is important for several reasons.
- Comfort: A smooth filling will not irritate the tongue or cheeks, and it will be more comfortable to bite and chew.
- Durability: A polished filling is less likely to chip or break, and it will last longer.
- Aesthetics: A polished filling will blend in with the rest of the tooth, and it will not be noticeable when you smile or talk.
To polish a filling, the dentist will use a rotating brush with a polishing compound. The polishing compound will remove any rough edges from the filling and create a smooth, shiny surface. The dentist may also use a dental floss to remove any excess polishing compound from between the teeth.
Polishing the filling is an important step in the process of filling a cavity. It helps to ensure that the filling is comfortable, durable, and aesthetically pleasing.

Question 4: Is it painful to fill a cavity?
No, filling a cavity is not painful. Dentists will typically use a local anesthetic to numb the area around the tooth before they begin filling the cavity.
Question 5: How long do fillings last?
Fillings can last for many years, but they may need to be replaced eventually. The lifespan of a filling will depend on the type of filling material used, the location of the cavity, and the patient's oral hygiene habits.
Question 6: What are the different types of filling materials?
There are several different types of filling materials available, including composite resin, amalgam, glass ionomer, and gold. Composite resin is the most popular choice for fillings because it is strong, durable, and can be matched to the color of the tooth.
