การอุดฟัน
Tooth filling is a dental treatment that dentists recommends to patients to replace missing tooth structure caused by tooth decay, or chipped or broken tooth due to external trauma, or worn-down or eroded teeth, or to close gaps between teeth (diastema closure).
Usually, dental fillings are used if the missing tooth structure is relatively small in size, however if tooth has lost too much dentin, our dentist would needs to examine the tooth with x-ray to determine if tooth filling is still possible to restore the tooth.
In general, the dentist will make a diagnosis, and then plan a treatment after it has been considered that the decay has not spread inside the tooth nerve cavity and the overall tooth condition should be in a relatively normal condition, which means, there is no pain and swelling around the tooth to be filled.
Procedure
• The procedure begins with tooth examination. Check all teeth the extent of decay, and which tooth can be treated with filling.
• Next, the tooth that is considered for filling, the tooth is prepared; the dentist will check for food particles that may have stuck inside the tooth cavity, and remove the decayed part of the tooth by grinding-down tooth until only the strong dentin is left. At times, the dentist would need to use topical anesthesia to reduce tooth sensitivity while grinding.
• Next, the tooth must be brushed to remove small particles from grinding before the filling material is inserted. The materials used in filling can be silver amalgam or tooth-colored composite resin. Today, with the advancement in dental procedures, composite resin has been widely used to restore teeth to look naturally beautiful.
Materials used for filling teeth
There are 2 types of materials for filling.
1. Resin composite – this material has teeth-like color, which is why it is best used to restore front teeth for its aesthetic value.
2. Silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper). This material is suited for back teeth for added strength for chewing and is much cheaper option, but it may not as visually aesthetic as resin composite filling.
Dentist advice that in order to prevent tooth decay and further deteriorating the condition of teeth, it is important to follow a healthy dental care routine to prevent tooth decay from coming back after tooth has been filled or for tooth decay not to develop on other area of teeth. There is a chance that tooth decay develops on the same area which could damage a larger part of tooth’s dentin, and then if that happens, teeth may require a more costly repair such as root canal treatment and crown.
