Minimally Invasive Dentistry utilize many techniques to prevent cavities and preserve as much tooth structure as possible.
This is what I see...
Note the black pits that is a cavity that if not treated will GROW and become
BIGGER or need a
ROOT CANAL or
EXTRACTION !
All the cavities and bacteria are removed...
This is what the cleaned tooth looks like.
NOTE how deep that cavity really was...
And then the filling is done. Looks like NEW! and best of all the cost of more invasive treatment is not necessary :)
AN OUNCE OF PREVENTION IS WORTH A POUND OF CURE!
