The process could be done :
- At Home
- In dental clinic.
Before whitening
After Whitening
Personally, I would love to use brightening terminology rather than whitening.The process @ procedure may decrease your teeth shade at a certain level, to make it brighter.
Anyway, the terminology is just a matter of perspective..no big deal.
The picture above - an example of a before and after the whitening ( brightening ) procedure.For this particular case, the procedure was done in my dental clinic.
