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.

Eaten in a fast food restaurant lately? If so, maybe you’ve noticed some changes in the big, colorful signs behind the counters. Many have begun promoting a few “healthier” selections (like salads and grilled items) and giving a more extensive listing of nutritional information. But there’s one thing you might not have noticed on those displays: a listing for soda among the beverage choices in the kiddie meal packages. That’s because they are no longer there.
Recently, Burger King quietly removed sugary fountain drinks from the in-store and online menu boards that show what you get with kids’ meals. They were following the lead of McDonalds and Wendy’s, both of which made similar moves in prior months. You can still get a soda with your kiddie burger if you specifically ask for one, but we’re hoping you won’t; here’s why.
For one thing, youth obesity has nearly tripled in the past three decades. As the U.S. Centers for Disease Control and Prevention (CDC) has noted, it’s now an epidemic affecting more than one in six children and adolescents. Many of the extra calories kids get are blamed on sugary drinks: According to a study by the Harvard School of Public Health, children’s daily calorie intake from these beverages rose by 60 percent in recent years. Obesity makes kids more likely to get many diseases, and can lead to problems in psychological and social adjustment.
But that’s not all. As dentists, we’re concerned about the potential for soda to cause tooth decay, which is still the number one chronic disease in children around the world. The association between sugary drinks and cavities is clear. So is the fact that tooth decay causes pain, countless hours of missed school and work, and expense that’s largely unnecessary, because it’s a disease that is almost 100 percent preventable.
While the new signage at fast food restaurants won’t make soda disappear, it does tend to make it less of an automatic choice. Anything that discourages children from routinely consuming soda is bound to help — and let’s point out that the same thing goes for other sweet and acidic beverages including so-called “sports” and “energy” drinks. It’s best to try and eliminate these from your child’s diet; but if you do allow them, at least limit them to mealtimes, and give your mouth a break from sweets between meals. That gives the saliva enough time to do its work as a natural buffer and acid-neutralizer.
What else can you do to help keep your child’s oral hygiene in tip-top shape? Be sure they brush their teeth twice and floss once every day, and bring them in for regular checkups and cleanings. But if you do suspect tooth decay, don’t delay treatment: Left alone, decay bacteria can infect the inner pulp of the tooth, resulting in severe pain, inflammation, and possibly the need for root canal treatment.

Contrary to what you might think, a knocked out tooth doesn’t inevitably mean tooth loss. Time is of the essence — the shorter the interval between injury and replanting the tooth, the better the tooth’s long-term survival. The longer the interval, on the other hand, the less likely the tooth can survive beyond a few years. That phenomenon is due to the mouth’s natural mechanism for holding teeth in place.
The tooth root maintains its attachment with the jaw bone through an intermediary tissue known as the periodontal ligament. Tiny fibers from one side of the ligament securely attach to the tooth root, while similar fibers attach to the bone on the opposite side of the ligament. This maintains stability between the teeth and bone while still allowing incremental tooth movement in response to mouth changes like tooth wear.
While the ligament fibers will attempt to reattach to a replanted tooth’s root, the longer the tooth is out of the socket the less likely the fibers will fully reattach. An “ankylosis” may instead form, in which the root attaches directly to the jaw bone without the periodontal ligament. In this situation the body no longer “recognizes” the tooth and begins to treat it like a foreign substance. In all but the rarest cases, the tooth root will begin to resorb (dissolve); at some point (which varies from patient to patient) the attachment becomes too weak for the tooth to remain in place and is lost.
Ideally, a knocked out tooth should be replanted within 5 minutes of the injury (for step-by-step instructions, refer to The Field-Side Guide to Dental Injuries available on-line at www.deardoctor.com/dental-injuries). Even if you pass the 5-minute window, however, it’s still advisable to attempt replanting. With a subsequent root canal treatment (to remove dead tissue from the inner tooth pulp and seal it from infection), it’s possible the tooth can survive for at least a few years, plenty of time to plan for a dental implant or similar tooth replacement.

Many people have questions about the proper use of antibiotics — especially today, as the overuse of these medications has become a concern. It isn’t necessary for most people to take antibiotics before having a dental procedure. But for a few — notably, those with particular heart conditions and, in some cases, joint replacements — pre-medication is advisable. The question may be even more confusing now, because the standard recommendations have recently changed — so let’s try and sort things out.
First, why would anyone need antibiotics before dental treatment? Essentially, it’s because of the chance that an open wound could allow bacteria from the mouth to enter the bloodstream. For people in good health, the body is capable of quickly containing and neutralizing the bacterial exposure. But people with some types of heart disease, heart transplants, and/or total joint replacements have a greater likelihood of developing a bacterial infection, which can be dangerous — or even life-threatening. The same may be true of people whose immune systems are compromised.
At one time, people with a broad range of heart problems and artificial joints were advised to pre-medicate; today, new research indicates that fewer people need to take this step. Antibiotics are currently recommended before dental procedures if you have:
- An artificial heart valve, or a heart valve repaired with artificial material
- A history of endocarditis
- A heart transplant with abnormal heart valve function
- Cyanotic congenital heart disease (a birth defect where blood oxygen levels are lower than normal) that hasn’t been fully repaired — including children with surgical shunts and conduits
- A congenital heart defect that has been completely repaired with artificial material or with a device — but only for the first six months after the repair procedure
- Repaired congenital heart disease with residual defects, such as leakage or abnormal flow
In addition, not everyone who has an artificial joint needs antibiotic premedication. Instead, your health care providers will rely on your individual medical history to determine whether this step is required in your situation. However, having a compromised immune system (due to diabetes, cancer, arthritis, chemotherapy and other factors) is still an indication that antibiotics may be needed.
The question of whether or not to pre-medicate is an important one — so it’s vital that you share all relevant medical information with your doctors and dentists, and make sure everyone is in the loop. That way, the best decisions can be made regarding your treatment.
While tooth decay and periodontal (gum) disease destroy more teeth than any other causes, both of these diseases are largely preventable with proper oral hygiene and dental treatment. It’s more than possible, then, to enjoy a lifetime of healthy, disease-free teeth.
But even with healthy teeth, the effects of aging will cause tooth wear over time. And although we can’t prevent the aging process from occurring altogether, there are steps we can take not to accelerate the process.
Most tissues, including bone and teeth, have a growth cycle in which older cells are broken down (known as catabolism), removed and replaced by newer cells (anabolism). As we develop during childhood, the growth phase exceeds breakdown; when we reach adulthood, the two phases come into equilibrium. But as we age, breakdown will gradually overtake growth. This aging effect results in, among other outcomes, tooth wear.
“Normal” wear appears to be greatest — and most visible — along the biting surfaces of the teeth. The forces generated when we bite or chew causes enamel to erode over time. Unfortunately, you can accelerate this process through bad oral habits: clenching or grinding teeth, often times at night while you sleep, as well as habitually chewing on hard objects like nails or pencils.
Normal forces generated when we bite or chew are actually beneficial for dental health — they help stimulate bone growth. But when they exceed their normal range as when we clench or grind our teeth, they can increase tooth wear and cause other problems such as diminished function or changes in appearance, such as a shortened facial height.
To slow the rate of wear, it’s important to modify any behaviors that may be contributing to it. In many cases an occlusal night guard worn while you sleep helps prevent teeth clenching. You may also need assistance with stress management, a major trigger for these kinds of habits, through biofeedback therapy or counseling.
If you’ve already encountered excessive wear, bonding techniques using colored composite resin, veneers or crowns that attach directly to the teeth can restore lost function and rejuvenate the appearance and color of your teeth. We can perform a “smile analysis” to determine if one of these techniques is right for you to help you regain a more youthful and attractive smile.
