A Tip for Those Stubborn Contacts After Cementation
This situation has happened to me from time to time, and maybe some of you can relate. We place the cement in our restoration and light-cure it. Then we try to get the floss through and no dice! I would just tell the patient to come back in a few days and after eating on it a bit, the contact would open up for floss to fit through.
Well, I have used a few tools and tricks over the years to help open those stubborn contacts, both during cementation and direct bonding procedures, and I have fallen in love with the Axis Dental QwickStrips. They come in single- or dual-sided abrasives so you can smooth out contacts. They also have one with a serrated edge to get through bonded contacts. These work very nicely for those of you who do ortho/Invisalign and need to do some interproximal stripping of enamel.
QwikStrips come in coarse, medium, fine and superfine, and are color-coated. They are very easy to handle anywhere in the mouth. I'm a big fan of these and would highly recommend them if you ever run into those stubborn contacts!
