Teeth whitening 101: everything you need to know

Teeth WhiteningMost of us dream of having a beautiful bright, white smile, but sadly lifestyle factors can get in the way. Sometimes Mother Nature needs a little bit of a helping hand, and it’s not surprising to learn that teeth whitening is the most popular cosmetic dental treatment in the world.

Numerous things can cause staining of our teeth. Dietary factors, including drinking a lot of red wine, tea, or coffee, can lead to discoloured teeth, whilst unpleasant brown staining is one of the numerous negative side-effects of smoking.

The cosmetic dental team at Garden View Dental Care in Buckinghamshire have carried out hundreds of successful teeth whitening procedures, which is more often than not the best way to combat such everyday stains, restoring a natural bright whiteness to your smile. In some cases, this requires just a single hour-long appointment with the dentist.

In fact, the need for a dentist is the most important thing to remember about teeth whitening. Legally, only a dentist, or a hygienist or other suitably trained dental professional on the prescription of a dentist, can carry out the procedure, yet there are still beauty parlours offering whitening treatment. The General Dental Council (GDC) takes a very dim view of this and has carried out numerous successful prosecutions; however, it often only comes to their attention when someone has suffered damage to their teeth, gums, or mouth.

The teeth whitening products and procedures carried out in a dental practice are extensively tested and regulated, and have been proven to be safe, gentle, and effective.

Teeth whitening can take place in the dental practice, at home as a self-administered treatment under a dentist’s supervision, or both of these options can be combined. When you visit a dentist for a consultation, they will help you choose the best method for your needs.

Typically, home whitening takes a fortnight. It involves using gentle dental bleaching gel and custom-made mouth trays, which are worn overnight. A mouth tray must always be made by a dentist to ensure it fits perfectly, so that the bleaching gel only comes into contact with your teeth.

Avoiding a Modern Inevitability: Digital Eye Strain and Its Treatments

Human Eye

Human EyeThe human eye has more than one way of reading text, as is readily observable between words on paper and words on screen. A recent analysis found that it takes as little as three hours of monitor use a day to trigger the symptoms of what doctors are now referring to as Computer Vision Syndrome.

Digital Eye Strain or CVS affects a person’s eyes in a number of negative ways. These include but are not limited to itching, burning, dryness, redness, and blurred or double vision. Doctors also found that excessive monitor use links to symptoms such as headaches, low back pain, and psycho-social stress.

The report mentioned how more than 70 million workers worldwide are at risk of contracting DES, given their line of work. Individuals who “cannot work without a computer” may be setting themselves up for serious vision impairment down the line, as accountants, architects, bankers, engineers, flight controllers, graphic artists, journalists, academicians, secretaries, and students all consistently use monitors in their profession.

Of course, statistics have yet to take into account the millions of children and adolescents who spend the better part of their days looking at the screen. Separate studies have shown that the symptoms of CVS are already present among 70 to 90 percent of people who regularly use monitors.

Until the market sees products with screens that are easier on the eyes, doctors say that the best way for people to avoid the symptoms of CVS is by following the 20/20/20 rule. This involves taking a 20-second break every 20 minutes of screen use and focusing on points at least 20 feet away from the computer. With regular breaks, glare reduction as well as proper posture and distance, screen-dependent individuals can minimize the effects of eyestrain.
