Dental Filling

Dental fillings are used for cavity treatment whereby tooth decay is first removed and thereafter filled with tooth-colored fillings or amalgam fillings. BIDH general dentistry clinic is an amalgam-free clinic and uses composite resin for its dental fillings. 

Cavity Treatment

When you eat or drink foods with sugars, bacteria in plaque produce acids that can attack tooth enamel. If brushed well and regulary, plaque is kept in check. If plaque is not removed, its stickiness keeps these acids in contact with your teeth. Over time, the enamel of your teeth can break down causing cavities to form.

A cavity or tooth decay is a little hole in your tooth. The hard outer layer of your tooth, or enamel, has been damage. Bacteria can accumulate in tiny crevices of your tooth that causes acid build up which leads to decay.

Teeth Fillings

If a cavity is treated early, you will not likely need extensive treatment.It is recommended to make bi-annual visits to your dentist for a routine dental cleaning in preventing and checking for tooth decay.   Dental caries treatment varies with the severity of damage to your tooth starting with: 

  1. Fluoride treatments :  fluoride treatment may help restore your tooth enamel if a cavity is in very early stages and can sometimes be reversed.
  2. Tooth fillings : dental fillings are a type of tooth restorations and is the main treatment option for decay. Tooth cavity filling can be done with composite resins, porcelain or dental amalgams

If your cavity has progressed more extensively, more invasive treatments with dental crowns, root canal treatment or even tooth extraction may be diagnosed by your dentist.

Stages of Cavities and Types

Stages of Cavities

  • Tooth loses minerals on the outer surface
  • This is usually invisible to the naked eye
  • Areas where teeth touch are really vulnerable
  • White spots are the first visible signs
  • They appear near your gum line or near your braces
  • Part of the healthy tooth is destroyed. It has to be cleared of decay and filled with dental filling
  • If the tooth decay gets too deep, this can cause tooth damage, root infection and toothaches
  • If not treated at an early stage with simple dental fillings, you may need a crown
  • Or if the tooth needs to be removed, the missing gap later replaced with a bridge or dental implant

Types of Cavities

  • When healthy part of the tooth is damaged, it can be cleared of decay and filled with tooth-colored fillings
  • If the decay gets into the tooth root, root canal treatment followed by a crown may be required

  • Root cavities start on the tooth surface near the gums. Typically it is faster growing than regular cavities and more common in adults
  • Cavities near your root can make your teeth sensitive and painful when you eat, drink cold or hot beverages
  • As it is near your root area, it may affect your nerves caue sensititiy and pain
  • Secondary cavities usually stem from older fillings that crack or chip over time
  • Plaque and bacteria get under them and cause new decay
  • These secondary cavities need to be removed. The old filling is normally removed and the whole damaged portion re-fillled with a new fillling or depending extent of damage inlay, onlay or crown.

Tooth Filling Procedure

1. Examination, X-ray and Treatment Plan

Your dentist examines the extent of decay or cavity by looking at your teeth to determine the extent of tooth decay.  If your dentist suspects that the tooth cavity may be deeper, a small x-ray may be taken to check that specific tooth. A panoramic x-ray may also be requested to check the prognoses all teeth.

Dental fillings are best suited for minor decay and fractures.If this is your treatment option, your dentist discusses with you on suited dental filling to fill and seal a cavity. At BIDH, tooth colored fillings is typically recommended. 

2. Removal of Tooth Cavity

If you tooth filling is deep, local anesthesia may be administered to numb the area before the start of removing the decay in the tooth. For most cases, the cavity treatment is on the surface and do not need local anesthesia. 
The decayed or damaged of the tooth is prepared with a drilling handpiece.  The portion is cleaned and cleanse to remove any remaining bacteria or debris. Adhesives are placed and the filling material is applied to fill the cavity. Composite material is cured or hardened with blue color bonding light.

3. Tooth Filling and Polishing

Dental Filling FAQs

The recommended tooth decay treatment option for your case will depend on the extent of your caries. If there are small signs of caries but does not yet warrant a dental filling, fluoride treatment followed by consistent brushing can sometimes reverse the issue.

However, if the dental caries has damaged portions of your tooth, then dental fillings may be done. When the size of required dental fillings is large, onlays, inlays or overlays (that are porcelain pieces) may be recommended.

Assuming that the tooth decay has further significantly impaired the tooth, a crown may then done to fix the tooth. If the decay has infected the tooth root, root canal treatment would then be required.

Yes. When you chew, grind or clench, there is constant biting pressure that can cause tooth fillings to wear down, dislodge, chip, or crack. Decay-causing bacteria can work their way under the filling if the seal between the tooth and filling material has crevices. 

No. Essentially, you will need to have the old filling removed and a new tooth filling done. It is important to replace damaged or broken filling as soon as you can too avoid bacteria leaking through gaps of the broken filling. If left untreated, infection and more extensive treatment may be required. 

If your filling is broken or dislodged, you may experience a little pain when the tooth is exposed to the air or hot or cold temperatures. Make an appointment as soon as you can with your dentis. For interim relieve, applying a little dental cement that is available in drug stores can help reduce the sensitivity.

Depending on the type of material used, fillings usually last between seven to 15 years. If your filling is old and showing some signs of wear, it’s best to replace it before it cracks. Symptons that your dental filling may need broken or needs replacement :

  1. Your tooth hurts
  2. You feel pain when you drink cold beverages
  3. The old filling has become darker, slightly yellowish or changed color
  4. Part or the full filling has fallen out
  5. Your filling is old.  Dental filllings can last a long time, if it is 7 to 15 years and shows some signs of wear, it is best to have it checked before it cracks.
