How many types of tooth fillings are there?

• Tooth filling is a treatment that repairs decayed, cracked, or worn teeth with specialized materials, restoring their normal function. Fillings help stop the progression of cavities, reduce the risk of infection, and help preserve natural teeth for longer.
• Common warning signs that a filling is needed include sensitivity to hot, cold, or sweet foods, dark spots, cavities, or pain when chewing. Leaving these symptoms untreated can lead to further decay and more complex treatment.
• Post-filling care involves avoiding chewing on the filled side initially, refraining from eating hard or sticky foods, and maintaining regular oral hygiene with brushing and flossing. Regular checkups every six months are also recommended to prolong the lifespan of the filling.

Tooth filling is one of the procedures many people need throughout their lives because cavities, wear, and cracks are common problems resulting from eating habits, oral hygiene, and daily routines. Fillings are a treatment that stops decay from spreading, restores tooth function, and reduces the risk of future pain, root canal treatment, or extraction. This article explores the reasons for needing fillings, the types of filling materials, the procedure, and post-filling symptoms.

What is a filling? Why do we need fillings?

A filling is a dental treatment that uses specialized materials, such as composite resin or amalgam, to fill cavities, cracks, or wear in a tooth. This replaces damaged parts of the tooth, restoring its strength and normal function.

Fillings are crucial because they stop the spread of cavities, preventing bacteria from reaching the pulp, which can cause severe pain, infection, or the need for root canal treatment in the future. They also reduce tooth sensitivity, improve chewing efficiency, prolong the life of natural teeth, and lower the long-term costs of complex treatments.

What are the reasons for needing fillings?

Fillings are often necessary due to oral health problems and daily dental use. If left untreated, cavities can spread, leading to tooth pain, or eventual tooth loss. Common causes include:

1. Cavities from plaque and bacteria:
Plaque is a film of bacteria that adheres to the tooth surface. When consuming sugary or starchy foods, bacteria produce acid that damages the enamel, creating cavities. If left unfilled, the infection will spread deeper.

2. Cracked, chipped, or worn teeth from use:
Bite on hard objects, chewing hard food, or accidents can cause teeth to crack or chip, exposing the dentin and increasing the risk of infection. Fillings repair the tooth and prevent further damage.

3. Tooth wear from enamel-damaging behaviors:
Behaviors like brushing too hard, biting nails, or frequently drinking soda and acidic beverages thin the enamel, causing sensitivity and requiring fillings to protect the inner tooth structure.

4. Recurrent cavities under existing fillings:
Old fillings may deteriorate over time, creating small gaps where bacteria can penetrate and cause recurrent cavities. Refilling is necessary to stop the progression of tooth decay.

5. Cervical Caries:
Cervical caries often occur near the gums, a difficult-to-clean area with thin enamel. Fillings help prevent progression and reduce tooth sensitivity.

6. Caries from Crowded Teeth or Orthodontic Treatment:
Crowded teeth or teeth under orthodontic treatment are often difficult to clean, leading to food debris accumulation and resulting in cavities. Fillings are necessary to preserve the tooth's condition.

7. Caries from Low Saliva Production or Dry Mouth:
Saliva helps wash away bacteria and balance the acidity in the mouth. Low saliva production makes teeth more susceptible to decay. Fillings are necessary to prevent further damage.

8. Tooth Wear from Abnormal Chewing (Poor Occlusion):
Imbalanced occlusion or bruxism (teeth grinding) causes abnormal tooth wear, cracks, or pits. Fillings are needed to strengthen the tooth.

9. Early Childhood Caries from Bottle-Feeding or Sweets:
Children who drink bottle-feeding before bed or frequently eat sweets are at risk of rapid tooth decay. Tooth fillings help preserve baby teeth and prevent future problems with permanent teeth.

10. Age-related tooth decay:
As we age, tooth enamel thins, gums recede, and tooth decay becomes more susceptible. Tooth fillings are therefore a way to preserve natural teeth and ensure long-term tooth function.

Warning Signs That Need a Fill

Warning signs that a tooth needs a filling are often the early stages of decay or dentin damage. If you notice any of these symptoms, you should see a dentist promptly for evaluation and treatment before the problem progresses to more complex treatments.

• Tooth sensitivity when eating cold, hot, or sweet foods: This is caused by thin enamel or cavities, allowing these stimuli to directly contact the dentin.
• Punctures or pits on the tooth surface: This is a clear sign of advanced decay that requires prompt filling.
• Tooth discoloration, such as brown, gray, or black spots, indicates decay from within the tooth.
• Bad breath or a recurring bitter taste in the same area: This is often caused by food debris and bacteria accumulating in cavities.
• Tooth pain, especially when chewing, or a throbbing pain: This indicates that the decay may be deep and affecting the nerves.
• Swollen gums or pus around the tooth: This is a sign of infection that may result from untreated decay.
• Cracked, chipped, or fractured tooth: This exposes the dentin, making it susceptible to decay and infection.
• Abnormal tooth wear or difficulty chewing: This may be due to tooth deformation or decay, requiring a filling to restore its function.
• Teeth with persistent black spots or stains that don't disappear even after brushing are signs of tooth decay, not just ordinary stains.
• Food particles frequently stuck to the same tooth indicate that the tooth may have grooves or cavities that need filling.

What types of dental fillings are available? Which type is best?

There are many types of dental filling materials, each with different properties, durability, and suitability. The choice of filling material depends on the tooth's location, the severity of the decay, budget, and the patient's aesthetic preferences.

1. Composite Resin (Tooth-Colored Filling)

Composite resin is a white filling material that closely resembles the color of natural teeth. It's suitable for front teeth and easily visible teeth. The dentist will fill and shape it to blend in with the original tooth. The average lifespan is about 5-7 years, depending on care and tooth location. Advantages of composite resin include its aesthetic appeal, natural appearance, good adhesion to the tooth, and the ability to be completed in a single visit. Disadvantages include lower resistance to chewing forces than amalgam and potential discoloration over time.

2. Amalgam (Silver Amalgam)

Amalgam is a silver filling material that has been used for a long time. It's highly durable and suitable for molars that experience significant chewing forces. It has a long lifespan of approximately 10-15 years or more. Advantages include durability, lower cost, and long service life. Disadvantages include its less aesthetically pleasing appearance and noticeability when the mouth is open. And requires more tooth structure removal than other filling materials.

3. Glass Ionomer Cement (GIC)

Glass Ionomer Cement (GIC) is an opaque white filling material often used for children's teeth, baby teeth, or areas at the neck of the tooth that are not subjected to significant chewing forces. Its lifespan is approximately 3-5 years. Advantages include the ability to release fluoride to help prevent recurrent cavities, good adhesion to the tooth, and gentleness on tooth structure. Disadvantages include lower strength than other materials and easy wear when used in areas subjected to high forces.

4. Ceramic Inlay/Onlay

Ceramic inlays/onlays are special fillings made from ceramic in a lab and then bonded to the tooth. They are suitable for teeth with extensive decay or fractures, but not yet requiring a crown. Their lifespan is approximately 10-20 years. Advantages include high strength, beautiful color resembling natural teeth, no discoloration, and good resistance to chewing forces. Disadvantages include higher cost than regular fillings and the need for more than one treatment.

Preparing for a Tooth Filling

Preparing for a tooth filling is an important step that helps ensure a smooth treatment, reduces anxiety, and allows the dentist to plan the treatment more effectively. You should prepare as follows.

• You can eat before the procedure (it should be a light meal). Eat a light meal to prevent hunger after the procedure, as you may need to wait for the anesthetic to wear off before eating.
• Inform your dentist about any underlying medical conditions or medications you are taking, such as diabetes, high blood pressure, or regular medications, for safe treatment.
• Inform your dentist about any allergies to anesthetics, medications, or filling materials so that the dentist can choose the appropriate method and materials.
• Brush your teeth and clean your mouth before the procedure. This helps reduce bacterial plaque and makes the treatment more effective.
• Get enough sleep to relax your body, reduce stress, and help control blood pressure during the procedure.
• Prepare yourself mentally, especially if you are afraid of the dentist. You can tell your concerns to the dentist to make the treatment more comfortable.
• If it is a deep cavity, be prepared for an X-ray to assess the depth of the cavity and plan the appropriate treatment.
• Inform your dentist if you have experienced significant tooth pain or sensitivity to help diagnose and choose the right filling method.
• Avoid caffeine and alcohol before the procedure, as they may increase heart rate or increase anxiety during the procedure.
• It is not necessary to stop any medication. Unless it's a medication that affects blood clotting, you should always inform your dentist.
• Allow approximately 30-45 minutes for the dental procedure to ensure a relaxed treatment and optimal results.

Tooth Filling Procedure

1. Examination and X-ray (if necessary)
The dentist will visually examine the tooth and use specialized equipment to assess the location and depth of the cavity. If the cavity is deep or not clearly visible, an X-ray may be needed to view the root and inner dentin before planning treatment.

2. Local Anesthesia (if necessary)
If the cavity is deep or the patient experiences tooth sensitivity, the dentist will administer a local anesthetic to reduce pain. During the procedure, you may feel slight tightness or numbness, but you will not feel pain.

3. Drilling away decayed tissue
The dentist will use a drill to remove all decayed or damaged tooth tissue to prevent the spread of bacteria and prepare the area for the filling.

4. Placing the filling material
After cleaning the pulp cavity, the dentist will place the chosen filling material, such as composite resin or other materials, into the cavity and allow it to harden according to the specific material's hardening procedure.

5. Shaping, bite correction, and polishing
In the final step, the dentist will shape the filling to closely resemble a natural tooth, check for proper bite alignment, and polish the surface of the filling. To reduce plaque buildup and make using your teeth comfortable.

11 Ways to Care for Your Teeth After Filling

Caring for your teeth after filling is crucial to extending the life of the filling, reducing the risk of recurring cavities, and ensuring your tooth functions normally. Proper care will help keep your teeth strong and prevent future problems. Here are some tips:

1. Avoid chewing on the filled side until the anesthetic wears off (1-2 hours).
During the numbness period, you might accidentally bite your cheek or tongue, or chew too hard. Wait until your sensation returns to normal before using your tooth.

2. Avoid hard and sticky foods for the first 24 hours.
Hard or sticky foods can cause the filling to shift, become loose, or deform, especially new fillings that need time to fully harden.

3. Avoid drinks and foods that discolor the filling (in the case of composite fillings).
Tea, coffee, red wine, or dark-colored foods can easily stain and discolor tooth-colored fillings in the initial period.

4. Brush and floss as usual.
You can maintain your normal oral hygiene to prevent plaque buildup and recurring cavities. Brush gently and floss correctly.

5. If the filling is too high or you experience pain when chewing, see your dentist immediately.
6. A filling that is too high can cause malocclusion, jaw or tooth pain. It should be corrected by a dentist promptly.

7. Post-filling sensitivity is normal (1-2 weeks).
You may experience slight sensitivity to hot, cold, or sweet foods, which usually improves on its own. If not severe, this is normal.

8. If pain worsens, return for a check-up.
Severe or persistent pain may indicate deep decay or pulp inflammation.

9. Notice food particles easily getting stuck.
If food particles frequently get stuck in the same area, it may be a sign that the filling is not properly sealed. Return to your dentist for inspection.

10. Avoid chewing hard objects with your front teeth.
Biting hard objects like ice or shellfish with your front teeth can crack the filling or chip the tooth.

11. If you grind your teeth while sleeping, wear a night guard.
Teeth grinding during sleep accelerates tooth and filling wear. Wearing a night guard helps prevent damage.

12. Have a dental check-up every 6 months.
Regular dental check-ups help detect recurring decay or deteriorating fillings in their early stages. And it can be treated promptly.

Advantages and Disadvantages of Tooth Fillings

Advantages of Tooth Fillings

• Immediately stops the progression of tooth decay, helping to remove decayed tooth tissue and preventing bacteria from spreading further.
• Prevents future infections and tooth pain, reducing the risk of pulpitis.
• Restores normal tooth function, allowing for effective chewing and tooth use.
• Enhances the aesthetics of a smile, especially when using tooth-colored fillings that look natural.
• Quick, minimally painful, and time-consuming; most fillings are completed in a single visit.
• Relatively inexpensive compared to more complex dental treatments.
• A highly safe basic treatment with low risk, suitable for most patients.

Disadvantages of Tooth Fillings

• Filling materials have a limited lifespan and need to be replaced when they deteriorate over time.
• There is a chance of the filling falling out or breaking, especially when biting hard or chewing forcefully.
• You may experience tooth sensitivity after filling, which is usually temporary and will gradually improve.
• A filling that is too high may cause pain when chewing and may require adjustment.
• Some filling materials change color over time, affecting aesthetics.
• Fillings are not suitable for very deep cavities, which may require root canal treatment or a crown instead.
• The tooth may erode further if the filling is not properly fitted, leading to malocclusion and subsequent problems.

How long do fillings last?

The lifespan of a filling depends on the type of filling material, the location of the tooth, usage habits, and oral care. Generally, tooth-colored fillings (composite resin) last about 5-7 years, while silver amalgam may last 10-15 years or more. Ceramic inlays/onlays can last up to 10-20 years. Proper care, including regular brushing, flossing, and checkups every 6 months, can extend the life of a filling even further.

Does getting a filling hurt?

Generally, fillings are minimally painful because the dentist uses local anesthesia in cases of deep cavities or tooth sensitivity. During the procedure, you may feel a slight tightness or vibration from the instruments, but no pain. After the filling, you may experience some sensitivity or discomfort when chewing initially, which is normal and usually resolves within a few days to 1-2 weeks.

How long does it take to fill one tooth?

Filling one tooth takes an average of 20-45 minutes, depending on the depth of the cavity, the type of material used, and the location of the tooth. If the cavity is not deep and local anesthesia is not required, it may take less time. However, if the cavity is deep or requires X-rays and multiple adjustments, it may take a little longer.

What are some possible symptoms after a tooth filling?

Most symptoms after a tooth filling are normal and usually resolve on their own within a short time. Common symptoms include:

• Numbness in the tooth, lip, tongue, or cheek due to the anesthetic (usually disappears within 1-2 hours)
• Sensitivity to hot, cold, or sweet foods
• Slight tightness or irritation around the filled tooth
• Minor pain or discomfort when chewing
• A feeling that the filling is too high or that the bite doesn't fit properly
• Slight irritation or swelling of the gums around the tooth from the procedure
• Sensitivity when brushing or flossing in the initial period
• A temporary strange taste in the mouth after the procedure

If you experience severe pain, throbbing pain that persists for several days, pain that doesn't improve, or if you notice gum swelling and pus, you should see a dentist immediately.

What is the difference between a tooth filling and a root canal?

Tooth fillings and root canal treatments serve different purposes. A tooth filling is suitable for cavities or damaged teeth that have not yet spread to the nerve. The dentist will remove the decayed tooth tissue and fill it with a material to stop the decay from spreading.

Root canal treatment, on the other hand, is performed when the decay is so deep that bacteria have reached the nerve, causing severe pain or infection. It involves removing the infected nerve tissue, cleaning the root canals, and sealing the root. A crown is usually then placed to strengthen the tooth.
