Tooth Whitening for a Better Smile

tooth whiteningA beautiful smile can make impossible thing possible. Have you forgotten the heavenly smile of your daughter when she was just a baby? Unfortunately teeth are whiter in children and the whiteness reduces gradually as we grow older. This depends upon many factors. As we grow older, the enamel of the teeth becomes less porous, leading to easy deposition of dirt. Our eating habit, cigarette smoking, chewing tobacco, some antibiotics like tetracycline, habit of sipping excessive tea or coffee can endanger the white glow of our teeth of childhood. Therefore you need something to restore the whiteness. The teeth whitening procedure is at your service.

Teeth whitening or tooth bleaching is a cosmetic dentistry procedure. The dental surgeon removes the dirt and debris that pile up over your teeth for years with some modern techniques. Practically speaking, any product that can remove the dirt from the teeth can be a teeth whitening substance. This way, toothpaste is also considered as teeth whitener. And undoubtedly, if you brush your teeth regularly and in a scientific way, tooth paste can make your teeth glow for long. Tooth bleaching is a term that signifies artificially whitening teeth to such extent that the white color is much more than normally possible shade.

There are two methods available for teeth whitening – using a controlled laser beam to make the stain material in small particles and a teeth whitening gel that has to be applied over the teeth after wearing a protective tray. The gel contains bleaching materials in the form of hydrogen peroxide or carbamide peroxide. Their duty is to penetrate through the teeth enamel and oxidize the tough stain particles only to be expelled from inside. This debris accumulates over the protective tray.

The chemical can be applied either in a dentist’s chamber or there are take home kits. At the clinic, the doctor will first apply a protective gel over the gums to guard it from the harsh tooth bleaching agents. Then the bleaching gel is applied and the protective tray is put into proper place. After 15-20 minutes, when the bleaching process is over, the tray is removed. Generally the process has to be repeated depending upon the degree of staining. Using laser beams, the dentist tries to penetrate through to the inner dentin layer. In the cases of deep staining, this process only works. The whole procedure should not take more than an hour and you can go home just after the dentist finishes his job.

Tooth whitening is not a permanent procedure. It has to be repeated for some touch ups. The gap for each sitting depends upon the lifestyle of the person.

As every good things has its price, tooth whitening has some potential risks also. Chemical burn injury to the gums caused by bleaching agents is most common. Persons having weak gum (patients of pellagra and difficulty in blood coagulation process) should think twice before adopting a tooth whitening procedure. It is also not suggested below the age of 17 years (when most of the permanent teeth have erupted), pregnant and lactating women.

Tips for Getting Better Sleep

sleepDo you have trouble falling asleep, or toss and turn in the middle of the night? Awaken too early, or find yourself not feeling refreshed in the morning? You are not alone: millions of people struggle with falling and staying asleep.

Unless you’re suffering from a serious sleep disorder, simply improving your daytime habits and creating a better sleep environment can set the stage for good sleep. By developing a good bedtime routine and designing a plan that works with your individual needs, you can avoid common pitfalls and make simple changes that bring you consistently better sleep.

Better Sleep Tips I: Improving your daytime habits

How can what you do during the day affect your sleep at night? Better sleep starts with good daytime habits, from when (and how often) you exercise to what you eat and drink.

Regular day exercise can help sleep

Regular exercise, aside from many other wonderful health benefits, usually makes it easier to fall asleep and sleep better. You don’t have to be a star athlete to reap the benefits– as little as twenty to thirty minutes of activity helps.  And you don’t need to do all 30 minutes in one session: break it up into five minutes here, ten minutes there.  A brisk walk, a bicycle ride or a run is time well spent. However, be sure to schedule your exercise in the morning or early afternoon. Exercising too late in the day actually stimulates the body, raising its temperature. That’s the opposite of what you want near bedtime, because a cooler body temperature is associated with sleep.  Don’t feel glued to the couch in the evening, though. Exercise such as relaxation yoga or simple stretching shouldn’t hurt.
