Though it's been a while since Olivia Newton-John sang her way into our hearts in the movie Grease, her smile is as radiant as ever. Today, Olivia is still singing, acting and busy with new ventures such as authoring a cookbook and raising money for the cancer center that bears her name in Melbourne, Australia. Whichever part of the world Olivia finds herself in, she protects that beautiful smile with an oral appliance that many find beneficial.
“I wear a nightguard to prevent wear on my teeth, custom-made by my dentist,” Olivia recently told Dear Doctor magazine. “I love it!”
Olivia's device, also referred to as a bite (occlusal) guard, is designed for people who clench or grind their teeth at night, or during stressful periods. Made of thin, wear-resistant plastic, it is custom-made to fit exactly over your top teeth. This allows the bottom teeth to slide gently across the top teeth without biting into them. Not only does this prevent excessive tooth wear, it also helps relax the muscles of the jaw.
Grinding or “bruxing,” as it's also called, can affect virtually any part of the oral system: the jaw joints or muscles, resulting in spasm and pain; the teeth themselves, resulting in wear, fractures or looseness; it can even cause an aching in the ears, head, neck or back.
If you are a teeth-grinder, you might not even know it unless a sleeping partner hears it or your dentist notices signs of wear. These habits are called “parafunctional” (para – outside, function – normal), meaning the biting forces it generates are well outside the normal range — sometimes as much as 10 times normal. So it's no wonder that damage to teeth can occur if they are not protected.

When children begin losing their primary (“baby”) teeth, it’s a rite of passage — a sign that childhood is transitioning to future adulthood. And while it’s a normal part of dental development, it does bear watching for abnormalities.
Primary teeth are like deciduous tree leaves in that it’s their nature to shed and give way for new growth. They serve a purpose not only in providing children a means to bite and chew food, but also as guides for the permanent teeth that will soon erupt in their place.
As it reaches the end of its development within the jaw, the permanent tooth will begin to exert pressure on the primary tooth. This stimulates a process known as resorption where the primary’s roots begin to dissolve. This weakens its attachment to the jaw and the tooth becomes loose to the touch. At the end of this process, it doesn’t take much coaxing for the tooth to finally come out of its socket, with occasional minor bleeding and tenderness around the site. You will notice if you look at the bottom of the lost tooth that the roots have completely dissolved, leaving only a small indention.
This natural process, however, can run into complications. In their roles as permanent teeth guides, there’s a natural sequence for the loss of primary teeth; the permanent teeth develop along this sequence, which helps them erupt in the proper position. If a primary tooth is lost early and out of sequence (notably because of decay), the premature space can cause misalignment of the permanent teeth as they erupt.
That’s why it’s important for your child to have regular dental checkups, beginning sometime around their first birthday. This allows us to monitor primary tooth loss to make sure its progressing normally, as well as treat any condition such as tooth decay that could lead to premature loss. Regular checkups along with good oral hygiene practices will help ensure that the transition from primary to permanent teeth goes just as nature intended.

Sports drinks have grown in popularity since University of Florida football trainers developed Gatorade® in the 1960s. They're widely viewed as a convenient fluid and nutrient replacement after strenuous workouts. Recently, another beverage has become wildly popular — the energy drink, whose high caffeine promises heightened concentration and physical ability.
While energy drinks have raised health concerns, sports drinks are widely regarded as safe. Both kinds of drinks, however, may be a cause for concern when it comes to your dental health.
While both are substantively different, they do have one thing in common — both beverages contain high levels of citric and other acids to improve taste and shelf life. This high acidity can have a detrimental effect on tooth enamel.
When the mouth becomes too acidic after eating or drinking (4 or lower on the pH scale), the tooth's outer protective enamel begins to erode, a process known as demineralization. Saliva with its neutral pH of 7 can neutralize this over-acidity in about thirty minutes to an hour after eating and the enamel will actually begin to remineralize. But when there's an overabundance of acid, as with these beverages, saliva's neutralizing ability becomes inhibited. The mouth remains too acidic for a longer period, resulting in greater erosion of the enamel.
Generally speaking, we don't recommend energy drinks at all. If, however, you occasionally take in a sports drink, add the following precautions, if possible: combine the drink with a mealtime and rinse your mouth with pH-neutral water to wash away residual acid from the sports drink; and wait an hour before brushing your teeth — since some demineralization occurs before saliva neutralizes the acid, you could brush away some of the softened enamel before it can remineralize.
Finally, consider this: pure, clean water is still the best hydrator in the world. Replenishing your fluids with it after exercise might also be the better choice for your dental health.
