What do orthodontists do to put on braces?

For Comfort?: If I am understanding your question correctly, orthodontists provide/ dispense comfort wax to put on the fixed braces to prevent them from cutting or jabbing into your cheeks and gums during the initial stages of treatment. This can be plane or flavored. With clear aligners an orthodontist can provide whitening gels to simultaneously whiten teeth or a remineralizing paste to strengthen the enamel.

Braces: It's a simple and painless procedure. We use a material called etch to clean the teeth and prepare the glue to stick to the teeth. Then we put glue on the tooth and the back of the brace and then put the brace on the tooth. To harden the glue we use a bright light. Then put the wires in your braces.

Easy: Basically the same process as adding fake fingernails. First microscopically roughen the tooth with a mild acid for 30 seconds. Then adda coat of sealer (clear nail polish) and then place the bond on the tooth with the adhesive material in between. Most of us a curing light to set up the adhesive for 10-20 seconds and you're done. Place the wires into the brackets and you're ready to go.
