Stained teeth can be embarrassing — so much so you may even hesitate to smile. Before you seek out a whitening solution, though, there are a few things you need to know about tooth staining.
Tooth staining is more complex than you might think. There are actually two types: extrinsic, staining from foods and other substances of the outer surface of the enamel; and intrinsic, discoloration deep within a tooth that affects their outward appearance. The latter staining has a number of causes, including the type of dental materials used to fill a tooth, a history of trauma or the use of the antibiotic tetracycline during early tooth development.
There are some noticeable differences between the two types, although an examination is usually necessary to determine which you have. Extrinsic staining tends to be brown, black, or gray, or occasionally green, orange or yellow. Intrinsic staining can be red, pink or, if caused by tetracycline and fluoresced under ultraviolet light, yellow. If only one tooth is discolored it’s most likely intrinsic due to decay in the tooth pulp.
What can be done also depends on which type. Extrinsic staining can be modified through whitening, with either an office application or a home kit (there are differences, so you should consult with us before you decide). It may also be essential to modify your diet by restricting foods and beverages (coffee, wine or tea) known to cause staining and by eliminating tobacco use. You should also practice daily hygiene, including brushing with a toothpaste designed to diminish staining, and regular office cleaning and polishing.
Intrinsic staining can’t be addressed by these methods. Instead, you may need to undergo a procedure where we enter the interior of the tooth and insert a bleaching agent. If this isn’t an option, you can also choose a cosmetic restoration such as a porcelain veneer or crown that will cover the tooth to better match the color of your other teeth.
Dealing with stained teeth begins with a visit to our office to determine what type of discoloration you have and to learn your options. But regardless of what type you have, there is a way to a brighter smile.

We breathe every moment of every day and we’re hardly aware of it most of the time. But if you take the time to focus, you’ll find two possible pathways for your breath: through the nose or through the mouth.
While either pathway provides the air exchange needed to live, nose breathing offers better health benefits. Air passes through the nasal passages, which filter out many harmful particles and allergens. The mucous membranes in the nose also humidify the air and help produce heart-friendly nitric oxide.
Nose breathing also plays a role in your child’s facial and jaw development: the tongue rests on the roof of the mouth (the palate) and becomes a kind of mold around which the developing upper jaw can form. With chronic mouth breathing, however, the tongue rests just behind the lower teeth, depriving the upper jaw of its normal support. This could result in the development of a poor bite (malocclusion).
To avoid this and other undesirable outcomes, you should have your child examined if you notice them breathing mostly through the mouth, particularly at rest. Since chronic mouth breathing usually occurs because of an anatomical obstruction making nose breathing more difficult, it’s usually best to see a physician or an ear, nose and throat (ENT) specialist first for evaluation and treatment.
It’s also a good idea to obtain an orthodontic evaluation of any effects on their bite development, such as the upper jaw growing too narrowly. If caught early enough, an orthodontist can correct this with a palatal expander, a device that exerts gradual outward pressure on the jaw and stimulating it to grow wider.
Another bite problem associated with chronic mouth breathing is misalignment of the jaws when closed. An orthodontist can address this with a set of removable plates worn in the mouth. As the jaws work the angled plates force the lower jaw forward, thus encouraging it to grow in the direction that best aligns with the upper jaw.
Any efforts to correct a child’s breathing habits can pay great dividends in their overall health. It could likewise head off possible bite problems that can be both extensive and costly to treat in the future.
When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!
