Home whitening kits are a popular way to turn a dull smile into a dazzling one. But these self-applied products only work for teeth with outer enamel stains — if the discoloration originates inside a tooth, you’ll need professional treatment.
Known as “intrinsic staining,” this type of discoloration most often occurs within a tooth’s pulp or dentin layers. There are a number of causes like tooth trauma or tetracycline use at an early age. A root canal treatment used to remove infection from deep within a tooth can also cause discoloration: sometimes blood pigments left after tissue removal or the filling materials themselves can stain a tooth’s interior.
Intrinsic staining can often be treated by placing a bleaching agent, usually sodium perborate, into the tooth’s pulp chamber. But before undertaking this procedure on a tooth that’s undergone a root canal treatment,Â we want to first ensure the filling is intact and still adequately sealing the tooth from infection. We also want to make sure the supporting bone is also healthy.
If all’s well, we access the pulp in the same way as the root canal treatment, and preferably through the same access hole. We then clean out the pulp chamber of any stained matter and then ensure the root canals remain filled and sealed off from the pulp chamber.
We can then place the bleaching agent into the pulp, a process that will need to be repeated every three or four days to achieve the desired level of brightness. After each session we place a cotton pellet over the opening and held in place with a temporary adhesive; we can easily remove and re-apply this covering during subsequent sessions. Once we’ve achieved the desired color change, we seal the tooth with a permanent filling and restore the access cavity with a tooth-colored composite resin material bonded to the enamel and dentin.
There are other options for an intrinsically stained tooth like veneers or crowns that outwardly cover the discoloration. Internal bleaching, however, is a more conservative approach that causes less alteration of the tooth. If successful, it can restore a stained tooth to a brighter, more attractive shade.

If there's anything that makes Alfonso Ribeiro happier than his long-running gig as host of America's Funniest Home Videos, it's the time he gets to spend with his family: his wife Angela, their two young sons, and Alfonso's teenaged daughter. As the proud dad told Dear Doctor–Dentistry & Oral Health magazine, "The best part of being a father is the smiles and the warmth you get from your children."
Because Alfonso and Angela want to make sure those little smiles stay healthy, they are careful to keep on top of their kids' oral health at home—and with regular checkups at the dental office. If you, too, want to help your children get on the road to good oral health, here are five tips:
- Start off Right—Even before teeth emerge, gently wipe baby's gums with a clean, moist washcloth. When the first teeth appear, brush them with a tiny dab of fluoride on a soft-bristled toothbrush. Schedule an age-one dental visit for a complete evaluation, and to help your child get accustomed to the dental office.
- Teach Them Well—When they're first learning how to take care of their teeth, most kids need a lot of help. Be patient as you demonstrate the proper way to brush and floss…over and over again. When they're ready, let them try it themselves—but keep an eye on their progress, and offer help when it's needed.
- Watch What They Eat & Drink—Consuming foods high in sugar or starch may give kids momentary satisfaction…but these substances also feed the harmful bacteria that cause tooth decay. The same goes for sodas, juices and acidic drinks—the major sources of sugar in many children's diets. If you allow sugary snacks, limit them to around mealtimes—that gives the mouth a chance to recover its natural balance.
- Keep Up the Good Work—That means brushing twice a day and flossing at least once a day, every single day. If motivation is an issue, encourage your kids by letting them pick out a special brush, toothpaste or floss. You can also give stickers, or use a chart to show progress and provide a reward after a certain period of time. And don't forget to give them a good example to follow!
- Get Regular Dental Checkups—This applies to both kids and adults, but it's especially important during the years when they are rapidly growing! Timely treatment with sealants, topical fluoride applications or fillings can often help keep a small problem from turning into a major headache.
Bringing your kids to the dental office early—and regularly—is the best way to set them up for a lifetime of good checkups…even if they're a little nervous at first. Speaking of his youngest child, Alfonso Ribeiro said "I think the first time he was really frightened, but then the dentist made him feel better—and so since then, going back, it's actually a nice experience." Our goal is to provide this experience for every patient.
If you have questions about your child's dental hygiene routine, call the office or schedule a consultation. You can learn more in the Dear Doctor magazine article “How to Help Your Child Develop the Best Habits for Oral Health.”
Just like other parts of your physical body, teeth naturally wear as we get older. Just the effect from chewing during hundreds of thousands of meals in a lifetime can take its toll.
But there are some factors that can make tooth wear worse. By addressing them promptly should they arise, you can keep age-related tooth wear to a minimum.
Here are 3 areas to watch for to avoid excessive tooth wear.
Dental disease. Tooth decay and periodontal (gum) disease are most responsible for not only the loss of teeth but for compromising tooth health overall. But the good news is they’re largely preventable through proper oral hygiene practices to remove bacterial plaque, the main trigger for these diseases. Prompt treatment when they do occur can also minimize any damage and help your teeth and gums stay strong and healthy.
Your bite. Also known as occlusion, the bite refers to how the upper and lower teeth align with each other when you bite down. When they don’t align properly, regular chewing and biting can create abnormally high forces in the teeth and cause them to wear unevenly and more rapidly. Correcting the bite through orthodontic treatment won’t just improve your smile, it can improve bite function and decrease accelerated tooth wear.
Bruxism. This is a general term describing habits like teeth clenching and grinding in which the teeth forcefully contact each other beyond normal parameters. There are a number of causes for bruxism, but for adults it’s typically related to stress. Over time, bruxism can accelerate tooth wear and cause other problems like TMD. There are a number of ways to stop or at least reduce the effects of bruxism like relaxation techniques or a night guard worn during sleep that prevents the teeth from making forceful contact.
If you suspect you’re experiencing any of these factors, see us for a full examination. We’ll then be able to discuss your condition, the potential impact on tooth wear, and what we can do to protect your teeth.

There are a number of lifestyle changes you can make if you want to reduce your risk of oral cancer, with quitting a tobacco habit at the top of the list. You should also moderate your alcohol consumption and practice safe sex to prevent the spread of the human papilloma virus (HPV 16) linked to oral cancer.
And there's one other area that might be ripe for change—your diet. The foods we consume can work both ways in regard to cancer: some, especially processed products with certain chemicals, increase your cancer risk; more natural foods, on the other hand, can help your body fight cancer formation.
Although how cancer forms and grows isn't fully understood, we do know some of the mechanisms involved. One major factor in cancer growth is damage to DNA, the molecule that contains all the instructions for normal cell growth. Certain chemicals called carcinogens cause much of this DNA damage.
One example of these dangerous chemicals are nitrosamines, found in substances used to preserve meats like bacon or ham. Nitrosamines also occur in beer during the brewing process, some fish and fish products, processed cheese and foods pickled with nitrite salt. It's believed long-term consumption of foods with these chemicals can increase the risk of cancer.
On the other hand, there are foods with substances called antioxidants that help our bodies resist cancer. Antioxidants protect cells from unstable molecules called free radicals that can also damage DNA. You'll find antioxidants in abundance in fresh fruits and vegetables, especially those high in fiber. Vitamins like C and E found in many natural foods also have antioxidant properties.
So, to help keep your risk of cancer and other diseases low, make sure your diet includes mostly fresh fruits and vegetables, along with plant-based fats found in nuts or olive oil. At the same time minimize your consumption of processed foods with preservatives and other chemicals, along with animal and saturated fats.
A change in eating not only reduces your cancer risk, it can also improve your overall health and well-being. You'll also find a healthy diet can be dental-friendly—it can help keep your teeth and gums disease-free and healthy.

Unlike our primitive ancestors, our teeth have it relatively easy. Human diets today are much more refined than their counterparts from thousands of years ago. Ancient teeth recovered from those bygone eras bear that out, showing much more wear on average than modern teeth.
Even so, our modern teeth still wear as we age—sometimes at an accelerated rate. But while you can't eliminate wearing entirely, you can take steps to minimize it and preserve your teeth in your later years. Here are 3 things you can do to slow your teeth's wearing process.
Prevent dental disease. Healthy teeth endure quite well even while being subjected to daily biting forces produced when we eat. But teeth weakened by tooth decay are more susceptible to wear. To avoid this, you should practice daily brushing and flossing to remove disease-causing dental plaque. And see your dentist at least twice a year for more thorough dental cleanings and checkups.
Straighten your bite. A poor bite, where the top and bottom teeth don't fit together properly, isn't just an appearance problem—it could also cause accelerated tooth wear. Having your bite orthodontically corrected not only gives you a new smile, it can also reduce abnormal biting forces that are contributing to wear. And don't let age stop you: except in cases of bone deterioration or other severe dental problems, older adults whose gums are healthy can undergo orthodontics and achieve healthy results.
Seek help for bruxism. The term bruxism refers to any involuntary habit of grinding teeth, which can produce abnormally high biting forces. Over time this can increase tooth wear or weaken teeth to the point of fracture or other severe damage. While bruxism is uncommon in adults, it's still a habit that needs to be addressed if it occurs. The usual culprit is high stress, which can be better managed through therapy or biofeedback. Your dentist can also fashion you a custom guard to wear that will prevent upper and lower teeth from wearing against each other.
