Dental fillings and fissures seals
When a tooth is compromised by decay, the decayed tooth structure is removed and a filling is used to restore the tooth back to its original shape and function.
What is a filling?
Once decay has taken hold in a tooth, it will continue to damage more and more of the tooth, becoming more painful until treated by a dentist. A filling repairs the damage caused by decay and stops any more bacteria from entering the tooth. Fillings can be made of a number of different materials and can be used to repair any tooth in the mouth.
Types of fillings
What is the procedure?
First and foremost, thanks to modern anaesthetics and the way they are administered, getting a filling is virtually painless.
We will start by numbing the tooth and the area around it and then removing any decay with either a drill, air abrasion unit or a laser. The objective is to leave as much sound, natural tooth structure as possible. The cavity will then be disinfected and dried before a filling material (usually composite resin) is put in place. Once the material has hardened, we will shape it to look and feel just like a natural tooth.
Sometimes the pits and fissures in the back teeth are so deep that it is impossible for the bristles of a toothbrush to keep the surface clean. This can make it a breeding ground for bacteria which can result in decay. We may apply a dental sealant, commonly known as a fissure seal, to fill the pits and fissures and act as a barrier to plaque, bacteria and food debris.
How long does a filling last?
Fillings are situated in a warm, wet, bacteria-filled environment and are placed under constant stress and movement. Despite this, the average life of a filling is about 12 years. Sometimes things go wrong and a filling may crack, break or even fall out. However, with a regular oral hygiene regime, the life of a filling is substantial.
When a filling has just been placed, it is advisable not to eat or drink until the anaesthesia has worn off. This can take from one to three hours. Sensitivity to hot and cold drinks may occur for a few days after the procedure. Composite resin is completely cured by the time you leave our practice . As soon as the anaesthetic has worn, you are able to eat, chew and drink as normal.
If you experience any pain or the new filling simply does not feel right, see us immediately.
