If you’re considering tooth whitening, you may be torn between using a home product and undergoing a professional application in our office. Here’s a brief comparison of both approaches to help you in your decision process.
It helps first to know what we’re trying to correct — that dull, discolored tooth stain. Tooth staining comes in two varieties: intrinsic, which occurs deep within the tooth and can be caused by aging, old root canal treatments, tetracycline antibiotic use or excessive fluoride intake during childhood development; or extrinsic, which occurs mainly on the tooth surface and is caused by substances like coffee, tea, wine or tobacco. Intrinsic stains can only be treated through an in-office procedure — the comparison we’re making between home and professional whitening refers only to extrinsic staining.
Whitening, then, is the use of a chemical agent to bleach those stains. The majority of both home and professional products use hydrogen peroxide or carbamide peroxide (which also contains hydrogen peroxide) as its primary bleaching agent. Depending on the application, either of these chemicals can effectively bleach extrinsically stained teeth. The two approaches differ, however, in the strength of the bleaching agent: home products usually contain a 10% or less concentration, while professional solutions usually contain between 15% and 35%. As a result, the home application takes longer than a dentist’s treatment to achieve desired results — two to three weeks as opposed to one or two office visits.
Whichever option you choose, remember teeth whitening isn’t a permanent solution. The brightness will fade over time — six months to a year if you restrict foods and habits that stain teeth. You can also receive a touch-up once or twice a year to help extend brightness.
There’s also a middle of the road option — you can use a home application with guidance from our office. It’s also a good idea to visit us for an examination beforehand — we can then advise you on what options will work for your particular type of staining and teeth condition.
If you would like more information on teeth whitening options, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine articles “Teeth Whitening” and “Tooth Staining.”
When it comes to sensitive gums during pregnancy, Nancy O'Dell, the former co-anchor of Access Hollywood and new co-anchor of Entertainment Tonight, can speak from her own experience. In an interview with Dear Doctor magazine, she described the gum sensitivity she developed when pregnant with her daughter, Ashby. She said her dentist diagnosed her with pregnancy gingivitis, a condition that occurs during pregnancy and is the result of hormonal changes that increases blood flow to the gums. And based on her own experiences, Nancy shares this advice with mothers-to-be: use a softer bristled toothbrush, a gentle flossing and brushing technique and mild salt water rinses.
Before we continue we must share one important fact: our goal here is not to scare mothers-to-be, but rather to educate them on some of the common, real-world conditions that can occur during pregnancy. This is why we urge all mothers-to-be to contact us to schedule an appointment for a thorough examination as soon as they know they are pregnant to determine if any special dental care is necessary.
Periodontal (gum) disease can impact anyone; however, during pregnancy the tiny blood vessels of the gum tissues can become dilated (widened) in response to the elevated hormone levels of which progesterone is one example. This, in turn, causes the gum tissues to become more susceptible to the effects of plaque bacteria and their toxins. The warning signs of periodontal disease and pregnancy gingivitis include: swelling, redness, bleeding and sensitivity of the gum tissues. It is quite common during the second to eighth months of pregnancy.
Early gum disease, if left untreated, can progress to destructive periodontitis, which causes inflammation and infection of the supporting structures of the teeth. This can result in the eventual loss of teeth — again, if left untreated. Furthermore, there have been a variety of studies that show a positive link between preterm delivery and the presence of gum disease. There has also been a link between an increased rate of pre-eclampsia (high blood pressure during pregnancy) and periodontal disease. Researchers feel this suggests that periodontal disease may cause stress to the blood vessels of the mother, placenta and fetus.

Think of New Orleans, Louisiana, and what comes to mind? The sound of jazz pouring out from a nightclub in the French Quarter… the smell of shrimp boiling in a spicy gumbo… the fresh feeling you get after you’ve cleaned between your teeth with dental floss?
You may not know it, but besides its culinary charms and musical mojo, New Orleans has another claim to fame: It’s the historical home of dental floss. In the early 1800’s, a pioneering dentist by the name of Dr. Levi Spear Parmly recommended that his patients clean between their teeth with a silken thread. Long before the role of oral bacteria was recognized, it was Dr. Parmly’s belief that cavities were caused by foreign material on the tooth surfaces. But it took until nearly the end of the century for his invention to become available in handy dispensers. And the rest, as they say, is history.
Today, of course, we know much more about the causes and treatment of tooth decay. For example, we know that harmful bacteria in plaque — the sticky biofilm that builds up on your teeth in the absence of effective cleaning — release chemical substances that erode tooth enamel; this causes cavities (tiny holes in the tooth) to begin forming. We also know that while brushing alone helps remove plaque, it’s far and away more effective when combined with flossing.
Yet there’s one thing we’re still not sure of: Why don’t more people use dental floss regularly? Did you know that with careful attention to your oral hygiene, tooth decay is almost completely preventable? Plus, dental floss is now available in many different varieties: It’s no longer made of silk, but can consist of nylon or gore-tex thread; it comes waxed or unwaxed, round or flat… even flavored like mint or bubble gum!
So here’s our suggestion: Find a style of dental floss you like, picture yourself on Bourbon Street… and spend a few minutes flossing every day. Your teeth will say “merci beaucoup.”
