Tooth  filling  is a  medical  procedure carried  out  by  a  dentist  to fill  the  space  in  a tooth  once  the  decayed or  damaged  part  has  been  removed.  The  tooth  may  have become  infected  or  damaged  by  decay,  repeated  dental  work,  wear and  tear, gum disease,  cracked  fillings or an  injury to the  tooth.

To  achieve  the  procedure, a  replacement  material  is introduce  to protect  against further  damage  and  to restore  the  tooth’s  appearance  and  function.


  • It improves the structures of teeth. Composite filling help to improve the structure of the worst teeth. A tooth filling is a temporary solution so it is not harmful to teeth. 
  • Tooth filling includes the removal of the decayed or damaged portion of the tooth, which in a way protects the teeth from decay or further decaying of tooth and also dead of the tooth. 
  • Tooth filling restores the tooth to its original shape and allows normal function, while creating a seal that prevents reintroduction of bacteria into the tooth, and last for a long period of time.

 Tooth Sensitivity refers to the severe tingling pain or discomfort experienced while drinking anything cold, hot or eating anything which is sweet or sour. It is a common side-effect a patient can get after a dental procedure.  


Tooth sensitivity months after filling happens when the filling turns out to be very close to the nerve, as you bite down on crunchy things the pressure would drive the filling right into the nerve and produce a strange sensation. The “sensitivity” you are feeling is your tooth reacting to the placement of the filling material that replaced the decayed tooth structure in the cavity you had in the tooth. 

The tooth and the filling are made of two dissimilar materials which are not exactly compactible all of the time and this results in stimuli reaction of the tooth. There are two ways of recovery that the tooth can take after a filling is inserted.

In one way, the tooth reacts to the filling and either does nothing about it as a response, or in another way the tooth reacts to the filling a little by being slightly sensitive. The other happens in such a way that sensitivity is felt on the tooth, when the filling is either too large or too close to the pulp of the tooth which is the living tissue inside the tooth housing the blood vessels and nerves. In most cases this result in inflammation. 

For prolonged cases of increased sensitivity long after the filling was placed, this indicates that the pulp is now inflamed to the point of initiating “sensitivity signals”. When this happens, make an appointment with your dentist immediately so the pulp can be soothed by either removing the filling altogether or reducing it in size. 


The treatment involves desensitization and restoration of the damaged portion of the tooth which can be done by the dentist.   


A tooth  filling  can  help  treat  tooth  decay  and  also  prevent  further  decay.  There are  lots  of  materials that  a  patient  and  dentist  can  choose  from.  Here,  the  options are  narrowed  down  to three  types of  fillings;

(1) A COMPOSITE  FILLING : They  are  of course  the  best  and  most  visually pleasing  filling  material  for front  teeth  because  they  blend  so well  into the tooth.  They  can  also be  used  for  many  back  teeth  fillings.

A composite filling,  made  up  of ground  glass  filler  particles  in  a  polymer base,  is bonded to the  tooth  via a  bonded  layer  that  forms the  seal  at  the  edge  of  the  filling. If this seal  gives way,  cracks,  or  shrinks,  the  bond  breaks,  and  liquids  can enter  the  cracked  area  and  irritate  the  tooth.

(2) SILVER  AMALGAM  FILLING:  A silver filling  is best  utilized  where  moisture contamination  is expected.  Moisture  will  not adversely  affect  a  silver  filling. Drawbacks  to silver  fillings are  many:  they  are  not pretty  acceptable  in appearance  by  all,  they  don’t  bond  to the  tooth,  and  they  have their  makeup.

mercury in Silver amalgam  isn’t  just  silver  it  comprises of  a  mixture  of minerals that’s 50  percent  silver,  tin,  zinc,  and  copper,  and  50  percent mercury. It’s a  popular choice  for fillings among  dentists because  it’s strong, durable,  and  doe sn’t  cost  a  lot. sensitivity  if they  are  deep. 

(3) GLASS IONOMER  FILLING : Amalgam  fillings can  cause  thermal. There  are  also  used  frequently,  and  despite  a fairly rigorous bond  strength,  it’s possible  that  the  bond  may  fail and  allow leakage  and  sensitivity. Gl ass Ionomer fillings bond  to teeth,  are  toothcoloured,  and  are  somewhat  moisture  tolerant. 

The  drawbacks  remains there are not as  aesthetic  as composite  fillings and  are  not as  durable  when placed on  biting  surfaces. These  fillings are  good  for children whose  teeth  are  still developing.
