Everything you need to know about “Dental Fillings”

Dental fillings are not as scary as they might seem, but they are something we should all pay attention to. This procedure is essential in helping extend the life of our teeth, keeping them with us for longer, and protecting us from the serious issues that arise from tooth decay.

When it comes to dental fillings, most of us are familiar with this dental treatment, as it is a common procedure that we need to undergo when our teeth develop cavities. However, we might still have lingering questions such as: What exactly is a dental filling? Does it hurt every time? Why do we need fillings in the first place? And which type of filling is best for us?

To answer all of these questions, today, we’re going to dive into everything you need to know about dental fillings.

What is a dental filling?

A dental filling is a common dental procedure used to repair teeth that have been damaged by decay, wear, accidents, or cracks. The dentist uses various types of filling materials to fill or seal the damaged areas of the tooth, preventing further damage and restoring the tooth’s function, strength, and appearance. However, a tooth can only be treated with a filling if the damage has not reached the tooth’s nerve pulp, and there is still enough healthy tooth structure for the filling material to bond to.

Why is dental filling important? Why should we fill a decayed tooth?

Neglecting damaged teeth can allow bacteria, food particles, and other debris to accumulate in the cavities, cracks, or grooves, leading to a variety of oral health issues such as gum disease, abscesses, pulpitis (inflammation of the tooth’s nerve), root damage, and in some cases, it could even progress to oral cancer. A dental filling serves as an early solution, helping to prevent bacteria, germs, and food particles from getting trapped in the cavities, thus preventing further damage and more serious oral health problems.

What types of dental problems should be filled?

• Individuals with decayed, cracked, broken, worn, or chipped teeth, and still have enough tooth structure to hold the filling.
• People with teeth that are spaced too far apart; a filling can help reduce the gap between the teeth.
• Those who have previously had fillings, but the filling material has come loose, leaked, or the tooth has cracked further.
• Those who wish to change the shape or color of their existing filling material.
• People experiencing tooth neck wear due to improper brushing technique.

What are the materials used for dental fillings?

Dental filling materials are synthetic substances used to fill cavities in teeth, and they are divided into three main categories: metal-colored materials, and tooth-colored materials. Each type has its advantages, disadvantages, and suitability, as described below:

• Metal-colored material (Amalgam): This type of filling uses a mixture of mercury, silver, tin, and other metals. Amalgam is easy to use, fast, durable, and inexpensive. After filling, the material appears silver or gray in the filled area. Dentists often use this material for molars, teeth that are used for chewing, or teeth located at the back of the mouth.
• Tooth-colored material (Composite Resins): These fillings use a material that matches the natural color of the teeth, making them the most popular choice for fillings in visible areas. The material blends seamlessly with other teeth. Once the filling is done, you can use the tooth immediately without waiting 24 hours. However, the durability and strength of composite resins are not as high as metal-colored fillings.
• Tooth-colored porcelain (Ceramic Inlay-Onlay): This filling is made from ceramic material in a lab and then bonded to the tooth. The color matches natural teeth, and the material is durable with a lifespan of about 15 years. It is typically used for large fillings, known as inlay-onlay fillings, and tends to be more expensive than other filling materials.

How to prepare before a dental filling:

• Inform the dental staff and dentist about any underlying medical conditions, medications you’re currently taking, and any allergies to medications before each treatment.
• Brush your teeth, rinse your mouth, and clean your oral cavity before each dental visit.
• It’s advisable to eat beforehand, especially if you are getting a metal-based filling, as you must wait 24 hours before eating after the procedure.
• If you wear removable dentures or retainers, make sure to bring them with you.
• Ensure you get enough rest the night before your appointment to help your body relax during the treatment.

Steps for a Dental Filling:

• The dentist diagnoses the issue and plans the appropriate treatment. The dentist will clearly identify the exact location of the tooth to be filled.
• If the cavity is close to the tooth’s nerve, the dentist will inject a local anesthetic to alleviate pain and sensitivity.
• If there is an old filling, the dentist will remove the old material and treat the decayed area.
• The dentist will drill the tooth to remove the decayed part and prepare the tooth for the filling.
• The dentist fills the cavity with the appropriate filling material, shaping and adjusting it to ensure it fits when the teeth come together.
• In the case of tooth-colored fillings, the dentist alternates applying the material and curing it with LED light, layer by layer. The filling is then adjusted for a smooth and aesthetic fit.
• Once the filling is complete, the dentist polishes it to smoothness and checks the bite to ensure proper alignment.

Post-Dental Filling Care:

• If you have had a tooth filled with a tooth-colored material, you can chew food immediately. However, if the filling is made from metal, avoid chewing on the filled side for at least 24 hours.
• Avoid chewing sticky or hard foods that may stress the new filling.
• Mild pain, tightness, and tooth sensitivity after the filling is normal and should subside within a week.
• If you feel the filling is too high, causing your bite to feel off, or if chewing becomes painful, contact your dentist right away.
• Use a soft-bristled toothbrush and an antibacterial mouthwash to keep the area clean.
• Return to your dentist for a check-up every 6 months to maintain your oral health.

How much does a dental filling cost?

The cost of a dental filling varies depending on factors such as the type of dental issue, the complexity of the treatment, which tooth is affected, how many surfaces need to be filled, the material used, and the healthcare facility. Typically, the cost of a dental filling starts around 600-1,500 baht. If you’re considering a filling, it’s best to consult with a dentist first for a diagnosis and treatment plan.

FAGs

• Can dental fillings be covered by social security insurance?

Answer: Yes, social security benefits can be used to cover up to 900 baht per year for dental fillings.

• Can I skip getting a filling because I’m afraid of pain? Is it dangerous to leave a cavity untreated?

Answer: No, skipping treatment for a cavity can lead to more serious problems. A cavity left untreated will continue to expand and deepen, potentially causing issues such as tooth pain, loose teeth, tooth sensitivity, abscesses, gum infections, and more. In severe cases, you may need a root canal or even have the tooth extracted and replaced with a prosthetic.

• Is it better to get a filling or a dental implant?

Answer: It depends on the dentist’s diagnosis. If the tooth damage is minor and still suitable for a filling, the dentist will likely opt for that treatment. However, if the damage is severe and affects the root, the dentist may recommend a root canal or a dental implant.

• How long does it take to get a dental filling?

Answer: On average, a dental filling takes 30-45 minutes per tooth, depending on the location, the severity of the issue, and the complexity of the treatment, as well as the cooperation of the patient.

• Is getting a dental filling painful?

Answer: There may be some discomfort or sensitivity during the process of drilling the tooth, especially if the decay is close to the tooth’s nerve. However, don’t worry—your dentist will use a local anesthetic to numb the area and reduce any pain or sensitivity.

• Can I use porcelain instead of amalgam to fill molars?

Answer: It depends on the dentist’s diagnosis. If the tooth has significant damage, the dentist may consider using porcelain for the filling instead of other materials. However, this will also depend on the patient’s budget, as porcelain materials tend to be more expensive than others.
