Sports guards

January 2016

A report in The Times ( London) on 29 January 2016 says that Milos Roanic the Canadian Tennis player grinds his teeth  he became aware that this is affecting his spine ,posture and his feet while playing .He now wears a mouthguard to help solve the problem.His dentist found that at rest his jaw postures to the left. By wearing a device that helps to align his jaw his muscle tension has reduced as his jaw rests  in ther ‘right place’

The theory is that clenching your teeth pinches the nerves that run through the temporomandibular (jaw) joint, causing the body to produce the hormone cortisol, which increases your heart rate and blood pressure  and can trigger a fight-or-flight response. That’s good when you’re actually in danger but distracting when you’re playing golf or tennis. In theory, the aim is to improve physical and mental performance by preventing the sportsman from clenching. It also moves the lower jaw forward. The combination opens the throat, improving breathing. There is small but growing number of athletes wearing what manufacturers like to call “performance mouthpieces” while cycling, running or weight training. One of the newest tools in a performance-enhancement arsenal, these mouthpieces are light, flexible pieces of moulded plastic that fit over the teeth — and are only vaguely reminiscent of that retainer from junior high school or the bulky mouth guards worn by rugby players

Some people feel that the science is flawed because;

  • Stress causes the adrenal glands to release hormones that affect body function, but jaw-clenching is a result of hormone production, not the cause—and it does not cause stress throughout the body.
  • The temporary changes due to adrenal hormone release (such as increased blood flow to the muscles of the arms and legs) will increase performance of these muscles not “sap” it.
  • A few laboratory studies have found that the mouth guard use was associated with various things the researchers measured, but these may not be directly translated into increased performance during athletic events. There is also reason to doubt the validity of their findings. Most studies lacked appropriate controls, the numbers of people studied were small, and/or the researchers regarded small changes as significant when they were not. For example, one study Bite Tech cited found that participants reacted more quickly to sounds or a computer screen cue when they wore a mouthpiece than when they did not. But the average difference in reaction times between groups was only 18.5 thousandths of a second for the sound signal and 2 thousandths of a second for the visual cue. These differences have no practical significance.
  • Self-confidence can increase athletic performance, and belief in a product may increase self-confidence. But in the long run, success is far more likely to be based on natural ability and optimal training.

If the device improoves self confidence then it may be worth the  effort ( and expense)

21 st Century fillings

A few years from now millions of people around the world might be walking around with an unusual kind of filling material in their teeth.

Prolonging the life of composite tooth fillings could be an important step forward for dental treatment,since more than 122 million composite tooth restorations are made in the United States every year. An average person uses their teeth for more than 600,000 “chews” a year. Experience shows that the average lifetime of a large filling on a back tooth is limited due to tooth decay and material strength.(This is why your dentist may suggest a crown or overlay made of  porcelain or gold rather than a large filling.)

Bioactive glass from Oregon State University may help prolong the life of fillings which are made with bioactive glass should slow secondary tooth decay, and also provide some minerals that could help replace those being lost, researchers say. The combination of these two forces should result in a tooth filling that works just as well, but lasts longer.   +4402 84272543

Don’t Put Off ‘Til Tomorrow What Your Dentist Can Address Today

January 2016

Ideally, you’d never procrastinate in doing responsible, grown-up things.

But we’re all guilty of it.

For some, it’s finances: “I’ll pay my bills next week!”
Or housework: “Those dirty dishes can soak in the sink for a while.”
Or even shopping: “I’ll just take a package of  noodles to work for lunch…”

93194005All kinds of things get pushed aside on our daily to-do lists because we’d rather not tackle them now. But when it comes to your dental healthcare, procrastinating is ill advised. Sure, your time is precious, but your health is irreplaceable. And though many people don’t realize there are benefits to their wallet associated with dental visits, there are many. Yes, dental treatment can help your family budget’s bottom line!

How is that possible, you ask? How can spending money actually save you money? Well, consider preventive maintenance on your teeth like the regular tune-ups and oil changes y for your car. You rotate the tires so they wear evenly, and replace the air filter when it gets grungy. All so your transportation keeps transporting you where you need to go, and you don’t have to pay big bucks to replace a part that could have been protected with preventive measures.

You know where this logic leads, and why it’s even more important to pay attention to your smile than your car. Your teeth need that same attention to keep doing what they do so well. Without it, the chances of developing a serious problem are much higher. Gum disease, tooth decay, and oral cancer are all conditions your family’s dentist will check for during a routine exam. If you’re not keeping appointments on a regular basis, a problem could be developing and you’d never know. At least, not until you experience a symptom that signals there’s a problem—and by then, the issue has progressed far beyond what your dentist or hygienist could catch in a simple exam.

A cavity or signs of disease are much easier and cost effective to treat in the early stages, so don’t delay your dental visit any longer. Put off shopping for a bathing suit, but don’t put off caring for your smile!

A Gift You Can Give All Year Long

Holday Smile

January 2016

For most of us, gift-giving is just a holiday thing. Every year, we spend the time before Christmas looking for the perfect gift for those who are most special to us. But did you know there’s a very simple gift you can give your loved ones, and even strangers, any time you want? It’s your smile!

Believe it or not, smiling can have a remarkable impact on you and those around you.  According to scientific studies, it can improve one’s mood and even relieve stress.

Here’s how it works. When you smile, particular muscles in your face are stimulated. These muscles will, in turn, stimulate the part of the brain responsible for creating warm and pleasant feelings. Meanwhile, for those around you, a smile is simply hard to resist. Smiling at someone who’s having a hard day may inspire them to smile back, triggering those same pleasant feelings in them. That’s how smiling can easily become a gift you give someone else.

Has the  holiday season starting to worn you down? Practice your smiling. You may find that you start feeling better in no time. And why not make a New Year’s resolution to smile more throughout 2016. Just like regular brushing and flossing and twice-yearly checkups, committing to smiling throughout the year will help you enjoy better overall wellbeing and confidence.
