What Are Cavities OR DENTAL DECAY 0R CARIES?
A cavity is a decay in your tooth. A cavity develops when a tooth decays and develops a hole that grows bigger and deeper over time. Everyone is susceptible to tooth decay.
If a cavity is large and deep, food particles can become trapped in it.
Cavities are also called dental caries.
Symptoms of Cavities
The most common symptom is a toothache.
What Causes Tooth Decay?
Tooth decay is heavily influenced by what we eat, how well we take care of our teeth, and the presence of fluoride in our water and toothpaste. Heredity also plays a role in tooth decay.

TREATMENT OF DENTAL CAVITY IN FILLING OF TOOTH
What is a Filling?
1) A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc). Which Type of Filling is Best? No one type of filling is best for everyone. What's right for you will be determined by $ The extent of the repair, $ Whether you have allergies to certain materials, $ Where in your mouth the filling is needed, and the cost. Considerations for different materials include:  NO.1 AMALGAM(SILVER COLOUR) FILLING AND NO.2 COMPOSIT FILLING 1) Composite (plastic) resins OR TOOTH COLOURED FILLING are matched to be the same color as your teeth and therefore used where a natural appearance is desired. The ingredients are mixed and placed directly into the cavity, where they harden. Composites may not be the ideal material for large fillings as they may chip or wear over time. They can also become stained from coffee, tea or tobacco, and do not last as long as other types of fillings generally from three to 10 years. · As there is advancement in technology now high strength posterior materials available in market and tyey are used frequently by dentists(MOST COMMONLY USED) · · 2)Glass ionomer cement A self-hardening mixture of glass and inorganic acid. Usually used for small fillings, crowns, liners and temporary restorations. Advantages: releases fluoride (may provide help against further decay), completed in one visit, low incidence of producing tooth sensitivity, good esthetics. Disadvantages: Cost is similar to Composite resin, not recommended for biting surfaces and permanent teeth, could increase chance of periodontal disease(SECOND MOST COMMONLY USED) · · 4) 4) Gold fillings(NOT MUCH USED) 5) PORCELIN FILLING · If decay or a fracture has damaged a large portion of the tooth, a crown, or cap, may be recommended. Decay that has reached the nerve may be treated in two ways: through root canal therapy (in which nerve damaged nerve is removed) or through a procedure called pulp capping (which attempts to keep the nerve alive). If your dentist decides to fill a cavity, he or she will first remove the decay and clean the affected area. The cleaned-out cavity will then be filled with any of the variety of materials described above. THAANK YOU DR.AMIT.MOTWANI |
