Everyone wants to have white and beautiful teeth. If you find a hole in your tooth, you should fill it in time to avoid further expansion. So what is the best material for filling dental cavities? What material is strong for filling dental cavities?

What material is best for filling dental cavities

1. Amalgam: It is composed of silver alloy powder and mercury in A permanent filling material prepared at room temperature. This material has stable performance, is strong and durable, and its resistance performance is equivalent to that of tooth tissue. It is currently the most commonly used and ideal filling material for posterior teeth. But it also has its shortcomings, such as the color does not match the teeth; it has no adhesive force, and it needs to be prepared in a suitable shape when filling teeth, so a certain amount of tooth tissue needs to be removed; it is a good conductor, and it needs a base to isolate external stimulation when filling teeth.

2. Zinc oxide clove oil cement: This material is easy to remove and contains clove oil, which can soothe and relieve pain and protect the dental pulp. Due to its low strength, it is often used as a material to cushion the cavity and protect the dental pulp during treatment. It is also often used as a temporary sealing material when sealing medicine.

3. Zinc phosphate cement: composed of zinc phosphate powder and phosphoric acid solution. It has high compressive strength, a certain degree of cohesion, and is a poor conductor. It can be dissolved in long-term contact with saliva and water. It is mainly used as a base material for cavities, a bonding agent for dental restorations, and a filling material for deciduous teeth. Since this material is irritating to a certain extent, it cannot be used directly as a base for deep caries, otherwise it will damage the dental pulp.

4. Glass ionomer cement: The color is close to the color of teeth, with high compressive strength, good adhesion, and little irritation to the dental pulp. It is often used as a base and filling material for front teeth. . Fluoride-containing glass ionomer cement has a certain anti-caries effect. In addition, when using it as a filling material, it has the advantage of less grinding of teeth.

5. Composite resin: composed of resin and inorganic fillers. The advantages are beautiful color, small volume shrinkage and thermal expansion coefficient, insoluble in saliva, and good mechanical properties and bonding properties. But the wear resistance is poor. It is mostly used to repair defects in front teeth and cervical areas. Light-cured composite resin has a relatively stable color and is mostly used for the treatment of discolored teeth such as tetracycline teeth, fluorosis teeth, and dead pulp teeth.

Causes of tooth filling material falling off

1. Tooth fracture: Tooth fracture mainly occurs on dead pulp teeth. Dead pulp teeth have no nutritional supply and are easy to break. Improper use of teeth can lead to tooth fracture, which will definitely cause the filling material to fall off. Filling is generally not recommended for teeth after root canal treatment. Porcelain dental restorations can be used to protect the teeth.

2. Severely decayed teeth: For severe decayed teeth, which lead to large-scale damage to the teeth, showing deep caries, multi-faceted caries, etc., filling teeth in these cases can easily lead to the loss of filling materials; some serious cases Teeth with caries may also have unstable retention, which can easily lead to the loss of filling materials. For such dental caries, it is generally necessary to fix the teeth first, then perform porcelain tooth restoration, or perform tooth extraction.

3. The technology of the filling doctor is not good enough: The technology of the filling doctor is not good, and the filling material is not filled tightly. The filling is not tight, resulting in low bonding with the teeth, which will cause the filling material to fall off. When having tooth fillings, it is best to choose a professional and regular hospital.

4. Improper use by the patient: The filled teeth need to be protected by the patient and do not eat sticky and hard food. Due to the patient's negligence, the filling material will also fall off. of.

5. Improper repair of secondary caries: Each filling material is suitable for different tooth parts. Appropriate selection needs to be made when filling teeth. For secondary caries that cannot be filled, it is best to use Porcelain tooth restoration, because fillings are very ineffective when it comes to cavities, are prone to problems, and waste a lot of time and energy on the part of the patient.

6. Filling fracture: Filling fracture is more common in teeth where the tip of the tooth is in close contact with the filling material. The chewing pressure it bears is greater than that of other teeth. Medically, it is called traumatic occlusion. A common traumatic manifestation in the crown is crown fracture, especially in the proximal cavity, which causes the crown and filling material on one side to break. In clinical practice, metal shell crown technology is often used to repair and solve the problem.

How long does it take to fill a tooth cavity?

The time it takes to fill a tooth needs to be determined according to the specific situation of each person's teeth. The individual differences of the patients are quite different. According to the patient's dental caries Depending on the number, location, and degree of caries lesions, the filling time will be different. Early-stage tooth decay or defects generally only require a simple filling treatment due to the small scope of damage, and can be filled in half an hour at a time.

If caries is not detected and treated in time, as the caries develops from shallow caries to medium or deep caries, and when the damage is more serious, it is often necessary to remove the tooth nerve and perform root canal treatment. , the procedure is much more complicated and generally requires three to five visits to the hospital to complete.
