Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.
There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.
To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.
We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.
If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.

Professional Hockey player Keith Yandle is the current NHL “iron man”—that is, he has earned the distinction of playing in the most consecutive games. On November 23, Yandle was in the first period of his 820th consecutive game when a flying puck knocked out or broke nine of his front teeth. He returned third period to play the rest of the game, reinforcing hockey players’ reputation for toughness. Since talking was uncomfortable, he texted sportswriter George Richards the following day: “Skating around with exposed roots in your mouth is not the best.”
We agree with Yandle wholeheartedly. What we don’t agree with is waiting even one day to seek treatment after serious dental trauma. It was only on the following day that Yandle went to the dentist. And after not missing a game in over 10 years, Yandle wasn’t going to let a hiccup like losing, breaking or cracking nearly a third of his teeth interfere with his iron man streak. He was back on the ice later that day to play his 821st game.
As dentists, we don’t award points for toughing it out. If anything, we give points for saving teeth—and that means getting to the dentist as soon as possible after suffering dental trauma and following these tips:
- If a tooth is knocked loose or pushed deeper into the socket, don’t force the tooth back into position.
- If you crack a tooth, rinse your mouth but don’t wiggle the tooth or bite down on it.
- If you chip or break a tooth, save the tooth fragment and store it in milk or saliva. You can keep it against the inside of your cheek (not recommend for small children who are at greater risk of swallowing the tooth).
- If the entire tooth comes out, pick up the tooth without touching the root end. Gently rinse it off and store it in milk or saliva. You can try to push the tooth back into the socket yourself, but many people feel uneasy about doing this. The important thing is to not let the tooth dry out and to contact us immediately. Go to the hospital if you cannot get to the dental office.
Although keeping natural teeth for life is our goal, sometimes the unexpected happens. If a tooth cannot be saved after injury or if a damaged tooth must be extracted, there are excellent tooth replacement options available. With today’s advanced dental implant technology, it is possible to have replacement teeth that are indistinguishable from your natural teeth—in terms of both look and function.
And always wear a mouthguard when playing contact sports! A custom mouthguard absorbs some of the forces of impact to help protect you against severe dental injury.

While sports like football, basketball and soccer have exploded in popularity over the last few decades, many Americans still have a soft spot for the granddaddy of them all: baseball. While technology has changed many aspects of the game, many of its endearing traditions live on.
Unfortunately, one baseball tradition isn’t so endearing and definitely hazardous to health—tobacco, primarily the smokeless variety. Players and coaches alike, even down to the high school level, have promoted or at least tolerated its use.
But there are signs this particular baseball tradition is losing steam. Not long ago, the San Francisco Giants became the first major league baseball team to prohibit tobacco in its home stadium—on the field as well as in the stands. The move was largely in response to a law passed by the City of San Francisco, but it does illustrate a growing trend to discourage tobacco use in baseball.
While smoking, chewing or dipping tobacco can certainly impact a person’s overall health, it can be especially damaging to the teeth, gums and mouth. Our top oral health concern with tobacco is cancer: Research has shown some correlation between tobacco use (especially smokeless) and a higher risk of oral cancer.
You need look no further than the highest ranks of baseball itself to notice a link between tobacco and oral cancer. Although from different eras, Babe Ruth and Tony Gwynn, both avid tobacco users, died from oral cancer. Other players like pitcher Curt Schilling have been diagnosed and treated for oral cancer.
Cancer isn’t the only threat tobacco poses to oral health. The nicotine in tobacco can constrict blood vessels in the mouth; this in turn reduces the normal flow of nutrients and disease-fighting immune cells to the teeth and gums. As a result, tobacco users are much more susceptible to contracting tooth decay and gum disease than non-users, and heal more slowly after treatment.
That’s why it’s important, especially in youth baseball, to discourage tobacco use on the field. While most of baseball’s traditions are worthy of preservation, the chapter on tobacco needs to close.
During your latest dental cleaning and checkup, your dentist notices a skin rash around your mouth. You sigh—it’s been going on for some time. And every ointment you’ve tried doesn’t help.
You may have peri-oral dermatitis, a type of skin rash dentists sometime notice during dental treatment. It doesn’t occur often—usually in only 1% of the population—but when it does, it can be resistant to common over-the-counter ointments.
That’s because peri-oral dermatitis is somewhat different from other facial rashes. Often mistaken as acne, the rash can appear as small red bumps, blisters or pus-filled pimples most often around the mouth (but not on the lips), nostrils or even the eyes. Sometimes the rash can sting, itch or burn.
People with peri-oral dermatitis often try medicated ointments to treat it. Many of these contain steroids that work well on other skin conditions; however, they can have an opposite effect on peri-oral dermatitis.
Because the steroids cause a constriction in the tiny blood vessels of the skin, the rash may first appear to be fading. This is short-lived, though, as the rash soon returns with a vengeance. Prolonged steroid applications can also thin the affected skin, making it more susceptible to infection and resistant to healing.
Peri-oral dermatitis requires a different treatment approach. The first step is to stop using any kind of steroidal cream, as well as moisturizers, ointments and both prescription and non-prescription medications. Instead, you should only use a mild soap to wash your face.
You may find the rash looking worse for a few days but be patient and continue to avoid ointments or creams. Your healthcare provider may also prescribe oral antibiotics, usually of the tetracycline family. It may take several weeks of antibiotic treatment until the skin noticeably clears up.
For most people, this approach puts their rash into permanent remission. Some, though, may see a reoccurrence, in which case it’s usually best to repeat treatment. With a little patience and care, though, you’ll finally see this persistent rash fade away.
You're not just a patient to your dentist—you're also a partner for achieving your best oral health possible. And it takes what both of you do to achieve it.
No doubt your dentist always strives to bring their "A Game" when providing you care. You should carry the same attitude into your personal oral hygiene—to truly master the skill of brushing.
Like its equally important counterpart flossing, brushing isn't mechanically complicated—you need only a minimum of dexterity to perform it. But there are nuances to brushing that could mean the difference between just adequate and super effective.
The goal of both brushing and flossing is to clean the teeth of dental plaque, a built-up film of bacteria and food particles most responsible for dental diseases like tooth decay and periodontal (gum) disease. Brushing removes plaque from the broad front and back surfaces of teeth, while flossing removes it from between teeth where a toothbrush can't reach.
While a lot of cleaning tasks require bearing down with a little "elbow grease," that's unnecessary with brushing—in fact, you may increase your risk of gum recession if you brush too vigorously or too often. All you need is to apply a gentle, circular motion along all tooth surfaces from the gum line to the top of the tooth—a thorough brushing usually takes about two minutes, once or twice a day.
Your equipment is also important. Be sure your toothbrush is soft-bristled, multi-tufted and with a head small enough to maneuver comfortably inside your mouth. Because the bristles wear and eventually lose their effectiveness, change your brush about every three months. And be sure your toothpaste contains fluoride to help strengthen your enamel.
One last tip: while it may sound counterintuitive, don't brush immediately after a meal. Eating increases the mouth's acidity, which can temporarily soften the minerals in tooth enamel. If you brush right away you might slough off tiny bits of softened enamel. Instead, wait an hour before brushing to give your saliva time to neutralize the acid and help re-mineralize your enamel.
Unlike your dentist partner, your role in caring for your teeth doesn't require years of training. But a little extra effort to improve your brushing proficiency could increase your chances for a healthy mouth.
