Orthodontics: Dental Braces in the 21st Century


Years ago, dental braces were only appropriate for pre-teens and teens having problems with their bite (malocclusion). Today, orthodontic treatments are not only for pre-teens and teens, but for adults as well. Close to 30% of all orthodontic patients in the India are adults. But it pays to start early for maximum effectiveness: the Indian Dental Association recommends that children receive an orthodontic evaluation by age seven.


A malocclusion is usually a restorative issue, since it may interfere with eating and speaking. It may also be an esthetic issue that involves cosmetic dentistry since a malocclusion may prevent the development of a beautiful, well-aligned smile or facial jaw lines.


No matter what your age, orthodontics can protect your bite (occlusion), maximize your teeth's effectiveness in performing their functions, and create a well-aligned smile. In orthodontics today, the teeth and underlying roots are repositioned, providing better support for the crown of the tooth. Orthodontic treatment can also rejuvenate your facial appearance by reshaping the jaw, neck, and lips, especially when combined with maxillo-facial surgical procedures.


Finally, well aligned teeth make oral hygiene easier to accomplish. In fact, today’s orthodontics has been associated with the benefits of greater esthetic appeal, more comfort and reduced treatment time.


The Orthodontic Evaluation

If you are a candidate for orthodontics, you would likely be referred by your Family Dentist to an orthodontist for evaluation of your bite. During the first orthodontic visit, your orthodontist may use several methods to develop an individualized treatment plan, including:


Oral, facial and functional evaluation (examination).

Intraoral and facial photographs.

Panoramic and cephalometric x-rays.

Impressions for models of the teeth and bite.


An orthodontist will review your dental records, perform a clinical assessment, take x-rays of your mouth and head, as well as make models of the teeth by creating an accurate impression of the teeth - all of which is studied in order to formulate the best plan.


During the second visit, your orthodontist will typically review the treatment plan and estimate the number of months for the active phase of treatment. The standard treatment phase is ONE year. After this, you may be required to wear a retainer for a while.


Orthodontic treatment time can vary, based on age, the required changes to produce a satisfactory outcome, and how closely you follow your treatment plan. For example, younger patients may respond more quickly to treatment than adult patients because the bones supporting young teeth are more pliable than older bones. But adults tend to follow treatment instructions more consistently than pre-teens.


In some cases the treatment time is longer. For example, oral surgery and recovery may be needed before or during the braces treatment.

Teeth Whitening: Customize Your Bright, White Smile

Teeth whitening is the most commonly requested cosmetic dentistry procedure. Teeth whitening falls into the cosmetic dentistry category because it is designed to enhance your appearance by reducing tooth discoloration and staining to elicit a brighter, whiter smile.

You may feel that your teeth are too discolored to ever be white again, but dentists are achieving amazing results with the newest whitening techniques.


The Prevalence of Tooth Discoloration


Tooth discoloration and staining is a relatively common problem. Teeth are porous and are therefore not stain resistant. Red wine, soda, coffee, and tea, among other food and drink, contribute to the discoloration of teeth over time. Medications such as the antibiotic tetracycline may cause significant staining, resulting in yellow, grayish teeth. Smokers’ teeth can become permanently stained if the discoloration is not treated in a timely manner.


Tooth brushing alone can’t brighten teeth dulled by years of exposure to such discoloring agents. In fact, people with dull teeth sometimes over-brush in an attempt to eliminate stains, and this can harm the enamel.


Teeth Whitening Considerations

More often than not, teeth whitening works adequately. Teeth whitening procedures performed by your dentist may potentially whiten your teeth up to 14 shades, correcting serious discoloration issues.


Occasionally tooth discoloration is so severe that whitening alone cannot fully treat the problem. Such situations may require a combination of whitening and the placement of custom porcelain veneers on specific discolored teeth. You may opt for veneer treatment alone rather than a teeth whitening regimen. Consult your dentist to determine the best course of action for your unique oral concerns.


Your dentist will also advise you to avoid food and drink that could stain your teeth for about a week, as well as to refrain from smoking.


The Teeth Whitening Procedure:

At-Home Teeth Whitening:


The most effective at-home whitening system is a prescription-strength gel kit your dentist provides. Most kits contain mouth trays that you fill with the whitening gel and place over your teeth for up to four hours.
