    Dental filling techniques

    Dental fillings (also known as dental fillings) are a dental procedure that uses artificial materials to fill in tooth tissue lost due to decay, chipping, or gaps between teeth. This technique helps restore the original shape of the tooth, improve chewing ability, make the tooth stronger, and reduce the risk of decay again.

    Dental filling materials used today

    Composite is a commonly used material, similar in color to natural teeth, safe and harmless. This method is also known as nanon porcelain coating.

    Advantages: The color is almost identical to real teeth, very suitable for filling front teeth.

    Disadvantages: Composite's lifespan is only about 5 years, shorter than Amalgam. Moreover, the bearing capacity of this material is also quite weak, so it is often not applied to large broken areas.

    Amalgam fillings (silver fillings)

    Amalgam dental fillings are a traditional silver filling method that is still popular today due to its low cost and high durability. Amalgam is a compound that includes mercury, silver, zinc, tin and copper.

    Advantages: This is a cheap and durable tooth filling method, with strong resistance. The average life of Amalgam can reach from 10 to 15 years.

    Disadvantages: Because it is a mixture of metal and mercury, it is not very aesthetic. This method is not suitable for filling front teeth or front teeth.

    GIC stands for glass ionomer cement, which is made from polyacrylic acid and fluoro aluminosilicate.

    Advantages: GIC does not contain fluoride, so it is very safe and benign, helping to prevent tooth decay effectively. In addition, GIC also has the ability to bond cracks together, minimizing cracking in fillings.

    Disadvantage: Not very aesthetic because the color is not very natural.

    Direct cosmetic dental filling procedure

    Step 1: Check and consult

    First, the dentist will examine the area of the tooth that needs to be filled, determine the size and advise on suitable filling materials.

    Step 2: Anesthetize and clean the tooth area

    The dentist will apply local anesthesia to the area of the tooth that needs filling. If the tooth has cavities, the decayed area will be cleaned with specialized tools, while food debris and tartar will be completely removed.

    Step 3: Filling the tooth

    The dentist will pour the filling material into the cavity or cleaned tooth position. The filling material is in liquid form and will gradually harden in about 40 seconds when exposed to a laser thanks to a photopolymerization reaction.

    Step 4: Adjust the filling area

    Finally, the dentist will adjust the filling, removing excess material. The filling surface is smoothed and polished to avoid feeling rough and uncomfortable for the tooth.

    Indirect filling procedure

    Indirect filling is a modern method that helps minimize the gap between the tooth tissue and the filling. The steps are similar to direct filling, but the difference is that the dentist will take a tooth impression to make the filling outside. The specific process is as follows:

    • Step 1: The dentist will examine the area of the tooth that needs filling, determine the size and advise on the type of filling material.
    • Step 2: Proceed to anesthetize and clean the area of the tooth that needs filling.
    • Step 3: Take dental impressions to shape the filling.
    • Step 4: Attach the filling to the tooth with specialized cement.

    With this method of filling teeth, the entire procedure will take about 2 appointments, each session lasting from 30 to 45 minutes.

    Although tooth filling is not too strange, understanding the knowledge as well as knowing when to fill cavities or gaps in teeth will help you improve your aesthetics sooner, have a confident smile and improve your quality of life.
