Dental Cavity Fillings FAQ

What is a dental filling?

A dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from decay (cavities) or external trauma. Fillings can also be used to repair cracked or broken teeth and teeth that have been worn down from misuse.

What types of dental fillings are available?

There are several types of dental fillings, including:

• Amalgam (Silver) Fillings: Made from a mixture of metals, these are durable and less expensive but more noticeable.
• Composite (Plastic) Resins: Tooth-colored fillings that blend with natural teeth, ideal for visible areas but less durable than amalgam.
• Ceramic Fillings: Made from porcelain, these are durable and aesthetically pleasing but more expensive.
• Gold Fillings: Durable and long-lasting, but more noticeable and expensive.
• Glass Ionomer: Releases fluoride to help protect teeth but less durable than other types.

How is a cavity filled?

The filling process generally involves:

1. Numbing the area around the tooth with local anesthesia.
2. Removing the decayed portion of the tooth using a drill or laser.
3. Cleaning the cavity to remove bacteria and debris.
4. Placing the filling material into the cavity.
5. Shaping the filling to match the natural contours of the tooth.
6. Hardening (curing) the filling material with a special light (for composite fillings).
7. Polishing the filled tooth to ensure a smooth finish.

How long does a filling last?

The longevity of a filling depends on the material used and the care taken.

• Amalgam fillings can last 10-15 years or longer.
• Composite fillings typically last 5-10 years.
• Ceramic fillings can last 15 years or more.
• Gold fillings can last 20 years or longer.
• Glass ionomer fillings generally last 5 years.

Do fillings hurt?

The process of getting a filling is usually painless because of the local anesthesia used to numb the area. After the procedure, there might be some sensitivity or discomfort, which typically subsides within a few days.

Can I eat after getting a filling?

It’s best to wait until the anesthesia wears off before eating to avoid biting your cheek or tongue. For composite fillings, you can usually eat as soon as the procedure is over. For amalgam fillings, it’s advisable to wait at least 24 hours before chewing on the filled tooth.

How can I care for my fillings?

Proper oral hygiene can help extend the life of your fillings:

• Brush twice a day with fluoride toothpaste.
• Floss daily to remove plaque between teeth.
• Visit your dentist regularly for check-ups and cleanings.
• Avoid hard foods and habits like nail-biting that can damage fillings.

Are there any risks associated with dental fillings?

Fillings are generally safe, but there are some potential risks:

• Allergic reactions to materials used.
• Tooth sensitivity to pressure, air, sweet foods, or temperature.
• Marginal leakage, where the filling does not bond perfectly to the tooth, leading to decay beneath the filling.
• Filling fractures or wear over time.

What happens if a cavity is not treated?

If a cavity is left untreated, it can lead to:

• Increased tooth decay, possibly leading to infection.
• Severe toothache.
• Tooth abscess.
• Damage to surrounding teeth and gums.
• Potential tooth loss.
