A little selfie-consciousness may be good
One recent study was conducted by NIH-funded researcher Dr. Lance Vernon (Senior instructor, Case Western Reserve University) three dentists from India, another researcher from the United States. They examined the feasibility of using smart phone video “selfies” to help improve toothbrushing technique. The small proof-of-concept study aimed to determine whether toothbrushing with selfie-taking was worth further study. As part of the study, Indian dental students were given a one-time toothbrushing training session. Then over two weeks, they recorded – on their phones in the privacy of their own home – five toothbrushing selfies. Later, the dentist researchers from India reviewed and characterized the selfies. With further analyses from my US colleague, we found some changes and variation over time in the quality and accuracy of toothbrushing. These changes may suggest that participants were trying to create a new habit, trying to change their behavior, almost as if, while taking the selfie, someone was watching them. The thought was that by using selfies, participants were more self-conscious about changing their ingrained toothbrushing approach and so may have been better able to “override” their habitual way of brushing. Also, the participants may have had more fun or been more curious about doing a sometimes mundane task. Habits are hard to change. One needs to overcome “muscle memory” to establish a new behavior. So relearning or retraining, just as with any sports-related skill, may be a gradual process, one prone to trial, error, forgetting and relapse. Some of our data might generally support this. But, based on the pilot study, it seems like adding the selfie to the mix could help people learn, well, new tricks. While it was a very a preliminary study, it opened a door. But keep in mind, it’s not just the taking of the selfie alone. Patients will need to review the selfies with their dentist or dental hygienist to get tips on how to improve and on the most important things to work on. Over time, this new, more effective brushing style could become your default habit. But then, you may need another selfie every so often, to make sure that the patient was not slipping back into old habits. An application of the toothbrushing selfie is that technology could be used to evaluate, monitor and permit providers to give real-time, convenient oral hygiene feedback to people across periods of time. This can help put a greater emphasis on prevention, which, at a minimum, should promote good dental checkups and could help keep costs down. Show us your toothbrushing selfies! We would gladly want to see them. READ MORE ABOUT THE STUDY- Your bite feels off. The TMJ’s position is dictated by where our teeth come together in our bite. So if your bite feels off or your teeth don’t fit together well, there’s a good chance your TMJ joints are off, too.
- You have pain around your forehead, temples, back of head or radiating down your neck. Ninety percent of pain comes from muscle: if your muscles are not functioning well because of fatigue from supporting one or both of your TMJ joints in an improper position, they produce pain. It’s much like when you exercise or work hard and feel muscle pain later. The only difference is that TMJ is more subtle and chronic.
- You have forward head posture. Our heads are supposed to be centered over our shoulders. If yours is in front of your shoulders when you are upright, you have “forward head posture.” That relates to your bite and your airway. The human head weighs about eight to 10 pounds; the farther forward it is off the center axis, the more strain it places on neck muscles and vertebrae.
- You snore. Snoring is a red flag that respiration during sleep is disturbed, Abeles says. Several factors can lead to snoring, but one of the most important is the position of the lower jaw, he says. If your lower jaw is a little too far back, then the tongue is farther back as well.
The drinks are especially popular among teens and young adults. Up to half of U.S. teens and young adults drink energy drinks, and more than half have at least one sports drink a day, according to the researchers.
Researcher Poonam Jain, BDS, MPH, associate professor and director of community dentistry at the Southern Illinois University School of Dental Medicine and her team tested 13 sports drinks and nine energy drinks for acidity. They tested six drinks for their effects on tooth enamel and found both types caused damage. Energy drinks, however, were twice as bad. Remember:damaged tooth enamel cannot be fixed.Jain's team immersed enamel samples from extracted human teeth into three sports drinks and three energy drinks.
They tested the acidity levels of all 22 drinks. They found the levels of acidity in the drinks vary between brands and between flavors of the same brands.
Sports drinks, energy drinks, and teeth: study details
Up to half of U.S. teens and young adults drink energy drinks, and more than half have at least one sports drink a day, according to the researchers. Other study results included:Gatorade Blue had the highest acidity among sports drinks. Next was Hydr8.
Among the energy drinks with the highest acidity:
- Red Bull Sugar=free
- Monster Assault
- 5-hour Energy
- Von Dutch
- Rockstar
MDX had the lowest acidity of the energy drinks.
The sports drinks tested were:
- Gatorade Rain
- Powerade Option
- Propel Grape
The energy drinks tested were:
- Monster Assault
- Red Bull
- 5-hour Energy
The enamel samples were immersed in the drinks for 15 minutes. The researchers transferred the enamel to artificial saliva for two hours.
This cycle was repeated four times a day for five days. The beverages were replaced with fresh ones every day.
The cycle was meant to simulate real life, Jain says, as some teens and young adults drink the beverages every few hours.
Enamel loss was evident after five days of exposure, Jain says.
The average enamel lost with sports drinks was about 1.5%, while the average loss with energy drinks was more than 3%. Jain says she cannot pinpoint what percent of enamel loss would cause problems.
Advice for sports drink lovers
Even one drink a day is potentially harmful, Jain says.
"If the consumer is absolutely unable to give them up, the best advice is to minimize [their use] and rinse with water afterwards," she says.
"Dilute them," she says. Do not brush immediately after drinking them, she says, as this could spread around the acid. "The mouth takes about 30 minutes to bring the pH back to normal. Wait an hour after drinking the sports or energy drink, to be safe, then brush."
It is very important to read labels on any drink you choose to prevent the cavities and gum disease that these drinks can cause. Also, be aware that the cream and sugar you put in your coffee in the morning has the same effect as other high sugar drinks.
The best drink of choice for the health of your teeth and gums is plain water. We're realistic though, and understand this can be difficult for anyone to regularly practice. If you’re going to have a soda or sweetened drink, be careful to drink them all in one sitting rather than sipping for a long time, and try to have a drink of water when you’re finished.
