How do you determine the need for fillings?
Your dentist can use several methods to determine whether you have caries (decay) of teeth:

Observation – Some white spots on your teeth may indicate decay, but not all. Your dentist may use an exploratory probe, a metal instrument with a sharp tip, to investigate the possible demolition.
Color caries detection – This is distributed on your tooth. Color will ascend decayed areas and easily rinsed from healthy ones.
X-rays – X-rays can help your dentist detect caries which does not appear on the surface. However, X-rays are not accurate in detecting minor damage to teeth in occlusal surfaces (upper). Current fillings or other restorations can also block the appearance of caries.
Laser fluorescent lighting – Helps in detecting small changes caused by caries (tooth decay). It is useful for dimply areas and small cracks.
Decay (caries) is not the only reason you need for a filling. Other reasons include:

Cracked or broken teeth
Teeth that are worn from use of unusual habits, such as eating nails, teeth grinding, mechanical damage of belongings.
Steps up to a filling
When you visit your dentist for a filling, the dentist can give you local anesthesia to numb the area of ​​the tooth if it is necessary. Then, your dentist will remove tooth decay, using hand tools or a special fraise. The corrosion air and lasers can also be used to remove decay.

A device, which dentists call the turbine, uses metal cones called fraise to penetrate the enamel and remove decay. Fraises come in different shapes and sizes. Your dentist will choose those that are appropriate for the size and location of your tooth decay.

After the decay is removed, your dentist will create space to prepare it for filling. Different types of fillings require different configuration procedures, to ensure that they will stay in place. Your dentist can place a base or a coating to protect the nerve of the tooth. Base or layers may comprise the composition of resin, glass ionomer, zinc oxide and eugenol, or other material.

Some of these materials release fluoride to protect the tooth from further decay.

Before placing the filling, the dentist will scrape the tooth with an acid gel. This gel makes tiny holes on the surface of the tooth enamel. This enables the filling of a narrow sticky tooth. Bonded fillings can reduce the risk of leakage or decay under the filling.

Certain types of fillings are extinguished with a special light. This light strengthens (hardens) the filling material and makes it stronger.

Finally, after the filling is placed, your dentist will use Freza to finish and polish your tooth.

After placing the filling
Some people feel pain, after placing the filling. The tooth may be sensitive to pressure, air, sweet foods or cold. Composite fillings often cause sensitivity, but other types of materials can also cause sensitivity.

In most cases, the sensitivity will be gone within 1 to 2 weeks. Until then, you should try to avoid anything that causes it. If your tooth is very sensitive, or your sensitivity does not decrease after two weeks, contact your dentist’s office. People vary in their response to different materials. Your dentist will not know in any way how your tooth will react to a particular material.Temporary fillingsYou can set a temporary filling if:

Your treatment requires more than one meeting.
Your dentist will wait a short period of time to cure the tooth.
You have a deep decay and pulp (contains blood vessels and nerve) exposed during treatment.
You need emergency dental treatment.
Temporary fillings often contain eugenol, a component of clove oil, which people use for toothache.

Temporary fillings should not be there forever. Usually, they fall, break within a month or two. If you have a temporary filling, make sure to visit your dentist to get a permanent. If you decide not to, your tooth can become infected or other problems will occur.

When should I replace a filling?
Fillings do not last forever. They can change in color. Fillings get stained or dark yellow with time. When you chew, your teeth and any fillings in them have been subjected to tremendous pressures. Even if there are no other problems, some of the fillings will shed over time and will need to be replaced. A filling will be replaced much earlier if it falls, breaks or cracks.

Food debris and bacteria can seep down under a filling that is cracked or broken through. You cannot clean there, so bacteria feeds on food debris and form acid that causes tooth decay. Decay under a filling may develop before you notice it or it causes you pain. This is why you should have your fillings under regular review and will need to replace them when problems occur.

Fillings that fall
Fillings can fall for several reasons:

Unbearable force in your bite leads to or breaks the filling or tooth.
The material that is used for filling cannot bare the pressure applied on it. If you have broken a big part of your tooth, maybe a crown of porcelain is a good choice of treatment.
The scope of the tooth is contaminated with saliva during filling setting. This will prevent the connection of material and as a result fillings may fall.
Care of your fillings
Although some of the fillings can last for many years, the average life of an amalgam filling lasts about 12 years. Fillings of the composition cannot last that long.

Your dentist will evaluate your fillings during your visit. You may need an X-ray recording if the dentist thinks that stuffing can be cracked or slot, or to see if there is disruption under fillings.
