HowYouCanPreventTeethGrindingFromDamagingYourOralHealth

Life has changed dramatically over the centuries. But although our ancient forebears wouldn't recognize much of our modern world, they would be well acquainted with one particular oral habit that still persists. There's some evidence from archeological dental examinations that our ancestors also clenched or ground their teeth.

This habit of involuntarily gnashing, clenching or grinding the teeth together is most prevalent among children, although not considered a major problem at these younger ages. But it can continue into adulthood, as it does for one in ten people, and lead to an array of problems from worn teeth to jaw joint pain.

As to why adult teeth grinding occurs, researchers have proposed a number of possibilities. Some believe it may be related to the arousal response that occurs when a person passes through various stages of sleep. It also appears that certain psychoactive drugs can trigger it. But at the top of the cause list, teeth grinding is believed to be a physical outlet for stress.

Because of the possibility of multiple causes, there is no one method for treatment—instead, it's better to tailor treatments to the individual. Universally, though, patients who use drugs, alcohol or tobacco, all of which are considered contributing factors, may reduce grinding episodes by restricting their use of these substances.

It's also possible to reduce the incidence of teeth grinding through better stress management. People can learn and use individual relaxation techniques like meditation, mindfulness or biofeedback. For sleep-related teeth grinding it may also be helpful to forgo use of electronic devices before bedtime for a better night's sleep.

Dental treatments like an occlusal guard worn mainly during sleep can minimize the effects of nocturnal teeth grinding. This custom-made appliance prevents teeth from coming fully into contact with each other, thus lowering the intensity of the biting forces generated and preventing cumulative damage to teeth and dental work.

If you have symptoms like sore teeth and jaws, reports from your family hearing you grind your teeth, or catching yourself during the day clenching your teeth, make an appointment for a full examination. From there, we'll help you find the right combination of solutions to keep this old habit from complicating your oral health.

NotGettingaGoodNightsSleepYourDentistMayBeAbletoHelp

If you live an average lifespan, you'll spend more than 200,000 hours in blissful slumber. It's not a waste, though: You absolutely need this much sleep to maintain optimum physical and mental health. That's why the National Sleep Foundation recognizes each March as Sleep Awareness Month to highlight the obstacles to a good night's sleep. One such obstacle is obstructive sleep apnea (OSA)—and if you have it, we may be able to help you reduce the harm it may be causing you.

OSA is the blockage of the airway during sleep, usually when the tongue relaxes against the back of the throat. As the oxygen level falls, the brain arouses the sleeper to restore airflow. This only takes a few seconds before the person slips back into sleep, but it can occur several times an hour.

As this scenario repeats itself night after night, the person becomes deprived of the deeper stages of sleep they need to stay healthy. The long-term effect can even be life-threatening: Besides chronic fatigue and “brain fog,” there's also an increased risk of high blood pressure, disease or other serious health conditions.

But there are ways to reduce chronic OSA, the most common being a therapy known as continuous positive airway pressure (CPAP). A CPAP machine, prescribed by a medical doctor, consists of a small pump that streams pressurized air into the mouth through a hose and facemask; the increased air pressure in the mouth helps keep the airway open. It's a proven method, but not always a favorite with some patients who find it uncomfortable and restrictive to wear every night.

If you're in that camp regarding CPAP therapy, an alternative may be possible: oral appliance therapy (OAT), which dentists can provide. Worn in the mouth during sleep, this custom-fitted mouthguard-like appliance repositions the tongue so that it doesn't block the airway. There is a variety of mechanisms, but most involve a hinge that positions the lower jaw forward, which in turn pulls the tongue away from the back of the throat.

These less invasive OAT devices may be an alternative to CPAP therapy for people who have mild to moderate OSA and find CPAP machines difficult to use. If you've been diagnosed with OSA and CPAP therapy hasn't been a good fit for you, speak with us about an OAT device. It could help you overcome this common disorder and get the deep sleep you need for a healthy mind and body.

3ReasonsWhyTreatingCavitiesIsBecomingMoreEffective

If you've ever had a run-in with cavities, you know the drill (no pun intended): After getting a local anesthetic for pain, the dentist removes any decayed dental tissue, as well as some healthy tissue, and then fills the cavity to restore the tooth. It's an effective treatment protocol we've been using for well over a century.

It does, however, have its drawbacks. For one, although necessary, removing healthy dental tissue can weaken the overall tooth structure. The dental drill used during the procedure is also unpleasant to many people: Although it doesn't cause any pain thanks to the anesthetic, the sounds and pressure sensations associated with it can be unsettling.

But advances in dental tools, technology and techniques are addressing these drawbacks in traditional tooth decay treatment. In other words, treating a tooth with cavities today is taking on a lighter touch. Here are 3 reasons why.

Earlier detection. The key to effective treatment is to find tooth decay in its earliest stages. By doing so, we can minimize the damage and reduce the extent of treatment needed. To do this, we're beginning to use advanced diagnostic tools including digital x-rays, intraoral cameras and laser fluorescence to spot decay, often before it's visible to the naked eye.

Re-mineralizing enamel. One of the advantages of early detection is to catch tooth enamel just as it's undergoing loss of its mineral content (demineralization) due to contact with acid. At this stage, a tooth is on the verge of developing a cavity. But we can use minimally invasive measures like topically applied fluoride and CPP-ACP (a milk-based product) that stimulates enamel re-mineralization to prevent cavity formation.

Less invasive treatment. If we do encounter cavities, we no longer need to turn automatically to the dental drill. Air abrasion, the use of fine substance particles under high pressure, can precisely remove decayed material with less loss of healthy tissue than a dental drill. We're also using newer filling materials like composite resins that don't require enlarging cavities as much to accommodate them.

These and other techniques—including laser technology—are providing superior treatment of tooth decay with less invasiveness. They can also make for a more pleasant experience when next you're in the dentist's chair.
