Things You Need To Know About Dental Fillings
You may require dental filling if you have the problem of caries or tooth decay. There are a few methods your dentist can use in order to determine the need.
Tooth decay can be identified due to existence of discolored spots on your teeth but not all of the discoloration cases are necessarily resulted due to tooth decay. Your dentist may run a few other diagnostic measures such as use of an explorer or a metal instrument with sharp tip. If tooth enamel is in good health, it will resist the pressure by the probe. However, explorer needs to be used with extreme caution.
2. Cavity-detecting dye
This dye needs to be applied on the teeth. It sticks with the decayed area and can be cleaned easily from the healthy part of the tooth.
Dental x-rays are effective in determining the existence of tooth decay whether it is located on the enamel or under the surface of enamel in dentin. Nevertheless, x-ray image might not be conclusive if smaller cavities are to be examined. Moreover, dental restorations may also prevent x-rays from developing a better image.
4. Laser fluorescence cavity detection aids
These are the tools which can effectively find out the cavities especially in the pits and fissures on the chewing surfaces.
Getting the dental filling
When you go for the filling, your dentist may give you a local anesthesia to numb the area properly. Anesthesia is specifically importance when there is a requirement of removal of decayed area with the help of a drill. The removal can be carried out with the help of laser.
At first, your dentist is going to use a high-speed drill which specifically targets decayed area and the unsupported enamel of the tooth. When these portions are removed, your dentist will then start using low-speed drill to deal with the dentin. Since dentin is softer than enamel, it doesn’t require high-speed drill.
After removal of the decay, the dentist is going to prepare the space for filling. During this process, the dentist may use a base or a liner to cover the tooth pulp. This base or liner is usually made of composite resin, glass ionomer, zinc oxide and eugenol, or another material. Some of these materials may release fluoride due to which further decay can be prevented.
Your dentist may use bonded filling material to fill your teeth. The major prerequisite for this material to be used is the etching of enamel with the help of an acidic gel. This gel creates holes in the enamel. These holes basically get hold of the bonded filling and ensure proper sealing.
Most of the filling materials are hardened with the help of special hardening light. After placing the filling, your dentist will use burs to finish and polish the tooth.
