The professional teeth whitening process starts with a consultation with your dentist. Not everyone is a good candidate for teeth whitening, which is why you want to talk to a dentist before you have it done. If you have large fillings or crowns (caps) on your front teeth, teeth bleaching is not a good idea. Read more
We know that for most of our patients, their favorite part of a dental cleaning is how smooth and clean their teeth feel afterward, not to mention how shiny they are. Tooth polishing has long been part of the dental checkup routine ever since the 1700s when Pierre Fauchard, the father of modern dentistry, recommended it. However, if you’ve had your teeth cleaned recently (and you have, right?) you may have noticed that your dentist or hygienist didn’t polish every single tooth. That’s because the results of recent studies are changing how dentists and dental hygienists approach polishing.
First, let’s do a quick review of what happens during a dental cleaning appointment. The whole point of a dental cleaning is to remove plaque and tartar that has accumulated on your teeth. If not removed, this bacteria-laden debris can lead to cavities and gum disease. The hygienist will go after the most stubborn buildup with an ultrasonic tool, which uses the power of fine vibrations to break up tartar and water to flush it away. Next, the hygienist may use hand tools to remove any smaller spots of buildup and to smooth out the tooth surface.
After your teeth have been thoroughly cleaned and all the plaque and tartar removed, then it’s time for polishing. Most polishing is done with a tiny rubber cup that spins on the end of a hand-held wand. Before polishing your teeth, the hygienist scoops up some prophy paste onto the rubber cup. Prophy paste is like an extra-gritty version of toothpaste, which often comes in similar flavors. The hygienist then applies the prophy paste to your teeth, and the spinning of the cup polishes your teeth and removes stains. After rinsing your mouth, the hygienist may floss your teeth, then apply a fluoride treatment, which helps teeth absorb minerals that make them stronger.
In fact, removing surface stains is the primary purpose of tooth polishing these days. In the past, it was thought that polishing teeth to make them smoother made it harder for the bacteria-laden gunk that leads to gum disease and tooth decay to attach to teeth. It turns out that removing plaque and tartar during the ultrasonic scaling part of your hygiene visit is really what helps keep bacteria from adhering (plus your daily home oral hygiene routine, of course). While polishing certainly smooths out your teeth, it hasn’t been shown to make a huge difference in preventing gum disease or tooth decay. In fact, some studies have shown that polishing can even temporarily weaken your tooth enamel, making your teeth slightly more vulnerable until the outer layer of enamel grows back.
Many dental professionals now consider polishing to be primarily a cosmetic procedure. That’s why some dentists and hygienists only do selective polishing, in which they only choose certain teeth to polish, such as those with superficial stains that didn’t get removed by the ultrasonic cleaning or hand tools. So while polishing is certainly nice to get that perfectly smooth feeling after your appointment, don’t be alarmed if your hygienist doesn’t polish all of your teeth. Polishing is not as important to preventing oral problems as the ultrasonic cleaning and manual removal of plaque and tartar and tooth-strengthening fluoride treatments.
