FILLINGS

Fillings or restorations are necessary in cases of tooth decay.

How teeth decay 

The surfaces of our teeth are not flat but have grooves and cusps. When we eat food it gets stuck in these grooves. If not cleaned properly bacteria are deposited within this debris. This is the start of  the formation of  PLAQUE.

Plaque is a sticky invisible film of bacteria that is constantly formed on the surfaces of your teeth and gums. This plaque combines with sugars present in the food particles to form acids that in turn destroy teeth.

These acids attack the tooth enamel. With repeated attacks the enamel wears away and a cavity is formed. When the acids penetrate deeper they attack the second layer that is dentin.

How Teeth Decay

Filling

At this stage when tooth decay in the enamel or dentin the tooth can be restored to its original form and function by the dentist.

The dentist removes all the decayed part of the tooth. Next he fills the tooth. Most commonly used filling materials are of two types.

1. Silver Amalgam

2. Light cure composite resin

Magical change in appearance by replacing silver amalgam with light cure filling

Light cure composite resins have certain advantages over silver fillings. These are

1. It is tooth coloured

2. It bonds to the tooth surface

3. Its strength is much more than silver amalgam

4. Life of a resin filling is much more than silver amalgum.

Filling of teeth requires one sitting. It is a painless procedure. If tooth decay is not treated and allowed to spread the pulp of the tooth is destroyed which then needs root canal treatment that is longer and more expensive than a filling.
