Restorations/Fillings

Dental Filling

A dental filling is a restorative procedure used to repair teeth damaged by decay, cracks, or wear.
The dentist removes the decayed portion of the tooth and fills the cavity with a suitable material to restore its shape, function, and appearance.
Fillings can also be used for aesthetic purposes, such as closing gaps between teeth, correcting discoloration, or modifying the shape or anatomy of a tooth.

Time when dental filling is needed

Fillings are recommended for:

  • Cavities: To repair teeth affected by decay.
  • Cracks or chips: To restore the tooth’s structure.
  • Worn-down teeth: To rebuild the tooth’s surface.
  • Aesthetic purposes: To close gaps between teeth, correct discoloration, or modify the shape of a tooth.
  • Preventive measures: To seal deep grooves in teeth and prevent decay.

Materials used for fillings

Common filling materials include:

  • Composite resin (tooth-colored fillings): A blend of plastic and glass particles.
  • Amalgam (silver fillings): A mixture of metals, including silver, mercury, tin, and copper.
  • Glass ionomer: A mixture of acrylic and glass that releases fluoride.

Pros and Cons of different filling materials

Filling Type Pros Cons

Composite Resin (Tooth-Colored Fillings)

  • Aesthetics: Matches natural tooth color, ideal for front teeth.
  • Versatility: Suitable for small to medium cavities and aesthetic improvements.
  • Less invasive: Requires less removal of tooth structure.
  • Durability: Less durable than amalgam, especially in high-pressure areas.
  • Staining: May discolor over time with exposure to coffee, tea, or smoking.

Composite Resin (Tooth-Colored Fillings)

  • Durability: Highly durable and long-lasting.
  • Strength: Ideal for back teeth that endure heavy chewing pressure.
  • Aesthetics: Silver color is noticeable and less appealing for visible teeth.
  • Tooth structure: Requires more removal of healthy tooth structure.
  • Mercury content: Contains a small amount of mercury, which is safe but may concern some patients.

Glass Ionomer

  • Fluoride release: Helps prevent further decay.
  • Biocompatibility: Less likely to cause sensitivity or irritation.
  • Aesthetics: Tooth-colored and suitable for visible areas.
  • Strength: Less durable and not suitable for high-pressure areas like molars.

Process for getting a dental filling

  • Examination and X-rays:
    The dentist examines the tooth and takes X-rays to assess the extent of decay or damage. Early detection through clinical examination and X-rays is crucial to prevent extensive damage and costly treatments.
  • Anesthesia (if needed):
    Local anesthesia is applied if the cavity is deep or the patient is less tolerant of pain.
  • Decay removal:
    The decayed portion of the tooth is removed.
  • Filling placement:
    The cavity is cleaned, and the filling material is applied and shaped.
  • Polishing:
    The filling is polished to ensure a smooth and natural finish

FAQs about Restorations / Fillings

Does getting a filling hurt?

The procedure is generally painless, especially if anesthesia is used. For minor fillings or superficial decay, patients may experience minimal discomfort.

Not all filling procedures require anesthesia.

Anesthesia is typically used for deep cavities or for patients who are less tolerant of pain.
For minor fillings or superficial decayanesthesia may not be necessary.

Can a filled tooth get decayed again?

Yes, a filled tooth can still develop decay around the edges of the filling. Maintaining good oral hygiene and regular dental visits can help prevent this.

How can I prevent the need for fillings?
  • Regular dental check-ups:
    Early detection of cavities through clinical examination and X-rays can prevent extensive decay and costly treatments
  • .Good oral hygiene:
    Brush twice daily with fluoride toothpaste and floss daily.
  • Balanced diet:
    Limit sugary and acidic foods and drinks.
  • Fluoride use:
    Use fluoride mouthwash or treatments as recommended by your dentist.
  • Sealants:
    Consider dental sealants for deep grooves in molars to prevent decay.
What are the benefits of early detection and treatment?

Early detection of tooth decay through regular dental check-ups and X-rays allows for:

  • Minimally invasive treatment: Smaller cavities require less tooth structure removal.
  • Preservation of natural teeth: Timely intervention helps save the tooth from extensive damage or extraction.
  •  
How can I check for tooth decay?

Regular dental check-ups are the most effective way to detect tooth decay, dentist can detect decay clinically and with X-rays.

However, you can look for signs such as:

  • Tooth sensitivity to hot or cold
  • Visible holes or pits in your teeth
  • Discoloration or dark spots
  • Pain when chewing

If you notice any of these symptoms, consult your dentist for a thorough examination.

What is the importance of X-rays in detecting cavities?

X-rays are essential for:

  • Detecting hidden decay:
    Reveal cavities between teeth or under existing fillings that are not visible during a clinical examination.
  • Assessing the extent of decay:
    Help determine the depth of decay and whether it has reached the tooth’s nerve.
  • Planning treatment:
    Provide a clear view of the tooth’s structure, aiding in the selection of the most appropriate treatment.
How safe are dental X-rays and how often should I get them?

Dental X-rays are safe with minimal radiation exposure. The frequency depends on your oral health needs, typically every 1-3 years depending on the type of X rays, or as recommended by your dentist.

Can I eat or drink right after getting a filling?

The timing for eating and drinking after getting a filling can vary based on the material used:

  • Amalgam Fillings: It is best to wait at least 24 hours before chewing on the side of the mouth where the amalgam filling was placed. This allows the material to harden completely.
  • Composite Fillings: You can typically eat or drink right after filling, as composite materials are set after the curing with a blue UV light. However, be cautious with very hot foods and drinks until you are sure the anesthesia has worn off.
  • Glass Ionomer Cement: Similar to composite fillings, you can usually eat and drink after about 30 minutes. However, these materials can take longer to set fully, so it’s advisable to avoid sticky or hard foods for a few hours to ensure the filling stays intact.
Why do I feel sensitivity and pain after a filling?

Experiencing sensitivity and pain after a filling is common and often referred to as post-operative sensitivity. This can occur due to several possible reasons:

  1. Post-Operative Sensitivity: It’s normal to experience some sensitivity after a filling as the tooth adjusts. This sensitivity typically subsides within a few days.
  2. High Filling: If the filling is slightly too high, it can cause discomfort when biting down.
  3. Nerve Irritation: The decay may be too extensive and extend to pulp which irritates the nerves in the tooth, leading to sensitivity to hot or cold.
  4. Material Reaction: Some individuals may react to the filling material, resulting in discomfort.

Most sensitivity should resolve within a few days. If it persists or worsens, contact your dentist for further evaluation.

How can I repair a chipped tooth?

A chipped tooth can be repaired with dental filling for minor damage, veneers for aesthetic improvements, or crowns for severe chips.

Your dentist will recommend the best option based on the extent of the damage.
