Among the “to-do” items on your pre-dive checklist like “Pack wetsuit” or “Fill scuba tanks,” be sure to add one other: “Check my dental health status.”
While that may seem like an odd concern, the changes in atmospheric pressure you encounter while diving (or flying, for that matter) could amplify oral sensitivity and intensify pain if you have pre-existing teeth or jaw problems.
The reason for this is the effect of basic physics on the body. All anatomical structures, including organs, bones and muscles, equalize external pressures the body encounters. We don’t notice this at normal atmospheric pressure, but when we encounter an extreme — either lower pressure during air flight or higher pressure during a scuba dive — we may feel the effects of the pressure on any structure with a rigid-walled surface filled with either air or fluid. These structures can’t equalize the pressure as fast as other areas, resulting in pain or discomfort. This is known medically as “barotrauma,” or more commonly as a “squeeze.”
One structure in particular could have an effect on your upper teeth and jaws: the sinus cavities of the skull, particularly the maxillary sinuses just below the eyes. Their lower walls are right next to the back teeth of the upper jaw and, more importantly, share the same nerve pathways. It’s quite possible, then, for pain from one area to be felt in the other, commonly known as “referred pain.” A toothache could then be felt in the sinus region, and vice-versa.
During a squeeze, then, pain levels from existing problems in the teeth and jaws that were previously tolerable (or even unnoticed) may well become amplified as the pressure from the sinus cavity impinges upon the jaw. That dull toothache you’ve been having may suddenly become excruciating at 30,000 feet — or 30 meters under the surface.
That’s why it’s important to see us if you’ve experienced any signs of tooth decay, gum disease or TMD, including pain, before your next dive or air flight. And, if you encounter any significant pain while flying or diving, be sure you consult with us as soon as possible when you return. Taking action now could help you avoid a miserable, and potentially dangerous, flying or diving experience in the future.
If you would like more information on pressure changes and dental health, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Pressure Changes can Cause Tooth and Sinus Pain.”
Once they learn to walk, there's no stopping most children. Sometimes it can be a little jarring, as when you discover your toddler on top of the kitchen counter reaching in the cupboard on tip-toes for a snack!
Fortunately, children are fairly resilient. Unfortunately, they're not invincible — some of their adventures could result in physical injuries, especially to the highly vulnerable area of the mouth.
Even if you've carefully “child-proofed” your home, it's still best to be prepared for mishaps. Here are 3 common dental injuries and how to handle them.
Soft tissue injuries. Making contact with the ground or hard objects like furniture can injure the lips, tongue, cheeks or gums and cause bleeding, cuts or bruising. First, clean the area with clean water and a cloth or gauze as best you can, making sure there aren't any trapped pieces of tooth or dirt. Apply gentle, continuous pressure with a clean cloth to control bleeding, and apply ice packs or cold compresses for swelling. Don't apply bleach, aspirin or similar medications to open wounds. If the bleeding won't stop or the wounds look serious or deep, go to an emergency room.
Chipped or displaced tooth. A blunt force mouth injury can chip or push (displace) teeth out of position. In this case try to save any chipped pieces you find — your dentist may be able to re-bond them to the tooth. A displaced tooth is a dental emergency, so contact your dentist immediately. Don't try to re-position the tooth yourself unless it's completely knocked out.
Knocked-out tooth. Actions to take with a knocked-out tooth depend on whether it's a permanent or primary (baby) tooth. If permanent, rinse the tooth with clean water. Handle it by the crown (never by the root) and gently place it back in the empty socket. If that's not possible, place the tooth between your child's cheek and gum (if the child is old enough not to swallow it by mistake. You can also place it in a glass of cold milk. Get to a dentist or an emergency room as soon as possible — minutes count for a successful reattachment. Conversely, don't try to put a primary tooth back in its socket — you could damage the developing permanent tooth beneath the gum line. But do see a dentist as soon as possible for an examination.
Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
