Different  types of lasers within one treatment
		 
	  	
		
			Lasers treat  using  a single wavelength  of light that  sterilize and react  with  specific  materials  such as  hard  tissue  ..tooth  or  bone or soft  tissue such as  gingivai (gum)..  diode lasers also activate  whitening  materials,, er  yag and  co2  laser  don't   touch the  tissues   diodes sometimes   do so within the  treatments  when  it  is advantageous  to  do  so we  use  several  different  types  of  lasers  within  one  treatment ..thus  BENEFITING FROM THE  SPECIAL ABILITIES  OF  EACH  KIND
