Tooth decay

TOOTH DECAY is acid damage of the tooth enamel

•  by specific bacterial film containing specific bacteria
• The film of bacteria is called DENTAL PLAQUE or BIOFILM
• BIOFILM is often not visible 
• but you may feel the rough coating on your teeth with your tongue
• It takes about 18 months of bacteria attack for tooth decay to become visible on Xray as well as visually
• Early decay can be treated  with various products
  1: Colgate NF 5000 toothpaste
  2: Silver fluoride therapy
  3: Curasept products
  Dental advice is required for use of #1 #2 or #3
  
• in most cases the early decay can be stopped or reversed and no drilling is required

HOWEVER
Once decay has penetrated the tooth to a certain depth... 
Then drilling and filling is required
So think about this when decay is found on a tooth it has been there in some form for quite a while ( there are exceptions)

it's essential to use good therapeutic toothpastes 

ask your dentist for a recommendation
