1) What is a filler?
Filling teeth is to restore damaged or decayed teeth to normal state. When filling a tooth, the dentist must first remove the decayed dentin, clean the damaged part, and then inject a filler into the empty tooth cavity.
Fillers can not only prevent teeth from being infected by bacteria, but also prevent teeth from further decay. Fillers used to fill teeth include gold, porcelain, synthetic resin (similar in color to teeth) and silver powder (alloys of mercury, silver, copper and tin, and sometimes zinc).
2) What kind of filler is the best?
According to the situation of everyone, the fillers used are different. To determine the appropriate filling, the factors that must be considered include the damage of the teeth, whether you are allergic to some fillings, the parts of the teeth that need to be repaired, and the cost. Optional fillers include:
1. The gold filler is customized in the laboratory first, and then injected into the corresponding position. Gold fillings are not easily rejected by gingival tissue, and the validity period is more than 20 years. For the above reasons, many dental authorities believe that gold is the best filler. However, gold fillings are very expensive and need to be reviewed frequently by dentists.
2. Silver powder (silver) filler is durable and relatively cheap. However, the color of silver powder is deeper and more obvious than that of porcelain or composite filler, so visible parts such as front teeth are usually not used.
Synthetic (plastic) resin is the same color as teeth, so it looks more natural after use. Stir the filling in the tooth cavity until it hardens. However, synthetic fillers are not suitable for large-area filling because they will break or wear after a period of time. At the same time, drinking coffee, drinking tea or smoking for a long time will also make the filler produce color spots, so the life of synthetic fillers is generally only 3- 10 years, which is not as durable as other fillers.
4. Porcelain filling is also called porcelain inlay. These fillings are pre-ordered in the laboratory and then embedded in the teeth. This filler matches the color of teeth and is not easy to form tooth stains. Most teeth can generally be restored with porcelain materials. The required cost is equivalent to that of gold filler.
If the teeth are damaged in a large area due to decay or rupture, it is recommended to use a crown or a crown. If the tooth decay has reached the nerve, it can be treated by the following methods: root canal therapy (that is, removing the damaged nerve), or the so-called pulp covering method (that is, retaining the original nerve).
3) What is the process of filling teeth?
When a dentist fills a tooth, he will first remove the rotten tooth tissue and then clean the damaged part. After the cavity is cleaned, the above filler can be injected.
4) How do I know if I need a filling?
Only a dentist can decide whether you need a filling or not. The dentist will examine the surface of each tooth with a small mirror.
If any abnormality is found, special instruments will be used for further careful inspection. Dentists can also examine the whole mouth or a part of the mouth with X-rays. Dentists take corresponding treatment according to the degree of tooth decay.
5) Matters needing attention in filling teeth:
1. You can't eat within 2 hours after filling a tooth, and you can't chew with one side of the filled tooth within 24 hours.
2. You may feel uncomfortable with hot and cold food within 1 week after filling your teeth. If it is more than a week, you need to come to the hospital to register for a follow-up visit.
If you feel too high or the fillings fall off after filling, please register in the hospital.
4. Try not to chew hard food after the pulp is dry to avoid tooth fracture.
Anyone who can't restore the tooth shape by filling teeth needs to be repaired with crown (braces) and treated at his own expense.
