Options to Fix Cavities A Close-Up Look At Cavities
(This is what a dentist sees)

First example: 

Tiny Pit and Fissure Cavities- 
the most common cavities of the "Pepsi Generation" who grew up with fluoride in the water and Crest toothpaste

Very small area of decay, hardly visible

After the cavity was opened, the decay is evident

After laser-bonded filling

Second example:

Small Cavities-Leaky Old Filling

"Beware of the hidden decay down below,  for before you know, it will grow!"

Small area of decay under old filling

Filling removed showing decay underneath is very evident now

After laser-bonded filling

Third example:
Medium-sized Cavity-
The dentist's dilemma: should it be filled, onlayed or crowned to preserve its strength?

Leaking old silver filling

Medium-sized filling out.  Notice the decay present.

Medium-sized cavity fixed with laser-bonded restoration

Fourth example:
Large cavity 
under old filling-
No doubt about what's best
for these large problem teeth

Large, old, leaking, silver filling TOO big for a filling. Needs an onlay.

Filling out, decay evident.

After laser-bonded porcelain onlay
