When your dentist tells you that you have a cavity, a seal is necessary to protect the tooth from further decay, when choosing dental fillings.
In fact, if not sealed, caries worsens, and ultimately can lead to bone loss. Fortunately, the procedure is almost painless dental fillings, thanks to advances in dentistry. Therefore, there is no reason to avoid filling if your dentist recommends it.
One of the first things you should ask your dentist, for a seal, is the type of material used. Today there is many more options available sealing material in the past, and the choice depends on a combination of appearance, cost and function.
Once numb the area surrounding the cavity, the dentist remove damaged tissue by using a special dental drill, an instrument air abrasion or even a laser. The end result is the same, removal of damaged tissue. The instrument used depends in part on where the tooth decay is and how severe. Air abrasion is a relatively new dental technique that involves using a handheld device for spraying a thin stream of aluminum oxide particles on the area of the tooth to be removed.
Particles impinging on the tooth and is blown away the desired amount of tissue without producing heat or vibration. Most patients reported that the procedure is essentially painless. But if you have a very deep cavity or is in a tricky spot between the teeth, your dentist will likely use the dental drill.
Once the damaged material removed, your dentist will clean debris and place the filling in the cavity. If the cavity is deep, your dentist may place a liner over the cavity before making the shutter to protect the nerve of the tooth
