As we all know, a smile makes everyone feel better. But do you know why? There are several reasons. First of all, a smile relaxes the muscles of the face and calms the nervous system. There is a nerve called the vagus nerve and when you smile, the vagus nerve is activated, and the body relaxes more. Laughing actually sends more oxygen to the brain which helps the whole body feel better. As more oxygen circulates, it helps to flush the byproducts of the cells in the body and  effectively you are doing a cleanse.

During a smile, the neurons in your body release dopamine, endorphins and serotonin which are the neurotransmitters that reduce depression and aggression. These are the ‘feel good’ neurotransmitters. Think of it like a runner’s high, you feel really good, really light and airy when on a good run and things are clear and bright. The best thing about smiling may be that it is free and easy to do.

Along with increasing the ‘feel good’ hormones being produced, there is a reduction in the stress-enhancing hormones. These hormones are cortisol and adrenaline. Cortisol and adrenaline are great hormones when we are being chased by a sabretooth tiger that is intent on eating us, as our muscles go into a high-stress mode so we can basically run away faster. However, the lactic acid will build up and make those muscles very sore later on. This is why smiling helps, less of the stress hormones and more of the calming neurotransmitters.

Another reason for a big smile is that when you show those pearly whites, you are opening yourself up to others. You are telling other people that you are happy to see them and want to be around them. We are all creatures who crave companionship and when other people want to be around you, it makes you feel wanted and cared for. Just this feeling of companionship has its own healing power. When we open up to others, we stimulate endorphins to be produced, and this is certainly a great way to improve our health. And when the other person smiles back at you, they are now producing endorphins as well. So, make someone happy, smile at them, get their endorphins going and make it a better day for everybody!

Did you know that your tongue can hold fat deposits, just like your belly? If you were ever overweight in the past, your tongue would likely have fat deposits in it, and these are kind of hard to lose. The tongue, like any other muscle in the human body, needs to exercise. But like most patients who are referred to a myofunctional therapist, they don’t go, they won’t do it. It costs money and time, and they feel like it’s kind of silly to exercise this area of the body. Well, folks, it does work and does make lots of sense, so get out there and start exercising that tongue!

In so many cases where a patient has sleep apnea, the tongue is quite large and is full of fat tissue. This can readily be seen on an X-ray that shows the tongue and what can be seen is that the tongue is elevated because it is thick due to fat deposition. Like so many areas of the human body, if you exercise the tongue and surrounding tissues, the fat will decrease over time which will effectively open the airway for better breathing. Snoring usually reduces as well as the tongue becomes smaller and tighter. The tissues around the tongue also become more toned with these exercises so if you have sleep apnea, it might reduce as you exercise this area over time. In fact, in many of the dental sleep medicine training programs, it is taught that myofunctional exercises are mandatory to improve a patient’s health.

There are other obvious benefits to exercising your tongue.  Your speech and articulation of words are improved, caused by the weakness in the tongue. If you have Dysphagia (trouble swallowing), your ability to develop a stronger tongue able to move more easily and then swallowing becomes easier. Finally, another plus is the jawline. Tongue exercises include the muscles groups below the chin and toning of the jawline begins.

So once again, dear reader, consider sticking out your tongue and making it work like it has never worked before. Get that tongue at attention! Get that tongue out there into the real world! Make that tongue healthier, happier, and improve your life!

In the past, it was quite common for an orthodontist to order extractions of perfectly good teeth to make the process of moving teeth and creating space with the use of braces easier. So many children are now presenting with narrow arches and crowded teeth that it made sense (somewhat) to remove the crowded teeth, thus allowing the orthodontic work to go faster and easier. But somewhere along the way a few practitioners noticed that the removal of the bicuspid teeth would often cause the upper and lower jaws to collapse backward which would lead to a collapsing of the airway as well. They also rather astutely noticed that the palate would become smaller, which made breathing more difficult as well. There are still orthodontists today who practice the method of extracting the teeth to make room and the braces go easier. However, many more are learning that there just might be better techniques.

The extractions of impacted teeth are a completely different need but also can cause the same issue. In this situation, the teeth need to be removed because 1) the lack of space in the bone means the teeth cannot erupt or 2) the tooth is growing in the wrong direction or position. In this situation, the stress placed on the jaw joint can cause the disc to be displaced and in addition, put a strain on the muscles around the jaw joint.

Of course, another method of expansion is the good old-fashioned RPE (Rapid Palatal Expander), but even this has its issues. The RPE will often just open the palate rapidly and the midline suture might not form into solid bone — it might just be a cartilaginous suture that can move around over time. This would not be very effective. The reason is on a skeletal level this instability can cause changes and distortions in the cranium. Another approach to getting some expansion is to use the ALF appliance as much as possible with the understanding that a few months with the RPE might be OK.

Another problem that is frequently seen among dentists, pulling out bicuspids, which makes the upper and lower jaws move and therefore are no longer in the same position as previously. This change can affect how the condyles (top of the jawbone) fit into the sockets and in turn, can lead to a TMJ problem. When that condyle is re-positioned after extractions, it will no longer be in the same relationship to the disc that covers it. The disc can end up displaced over time. This is what can lead to head and neck pain. So many extraction patients end up with similar problems later in life.

There are some practitioners who will actually use a palatal expander to re-open the extraction spaces to put in dental implants to ‘restore’ what was taken away. This is actually a controversial topic. As we get a bit older, the bones in the skull do indeed become more solid and if you were to try expansion a lot — like the width of a bicuspid that had been removed — it might be too much for the body to handle. Does that make sense? It might be that the expansion is just too much of a  ‘stretch’ and moving bones around might lead to more pain. This is another reason why the more conservative practitioners would use the ALF appliance to get as much gentle expansion as possible while minimizing trauma to the facial bones.

So, in general, extractions for the sake of doing braces may not be the best idea. Be sure to be careful when considering this.
