They have absolutely revolutionised how treatments are done and made, what at one time were complex procedures, very easy to carry out- this being backed up by the use of digital imaging and computers. Lasers have rather eliminated the need for scalpels and drills, which is not such a bad thing because the reasons treatments took so long before was because the use of these instruments made for long healing times. The laser does the job of both these two without the damage and trauma to the mouth.
The perfect example is the placement of dental implants, a procedure that could take over 6 months to heal and recover from- they can be fitted in a day with the minimum of fuss! Lasers are also being used for such things like fillings and root canals, again, because they are quick and painless. You can contour gums with lasers and also carry out whitening treatments. What is even more amazing; they are being used today in surgeries in central Leeds- now that is amazing!!
