While there is a certain degree of overlap between the roles of a dentist and an orthodontist, it's important to understand the distinction. Essentially, all orthodontists are dentists, but only a small fraction of dentists have completed the additional 2-3 years of specialized training in a certified orthodontic program to become orthodontists.

Orthodontists primarily focus on the alignment of teeth and jaws to optimize oral function and aesthetics. On the other hand, dentists provide a broad range of oral health services, including cleanings, X-rays, and even surgical procedures, to help patients maintain a clean and healthy smile. Trust in our expert orthodontist, Dr. W. Glenn Lewis, for specialized orthodontic care.

The timing of your child's orthodontic treatment can be influenced by various social and psychological factors. While orthodontic treatment can be effective at any age, certain age-specific parameters can optimize the treatment process!

Typically, orthodontic treatment is recommended between the ages of 9 and 14. This age range is often when children lose their last primary teeth and their second permanent molars, also known as twelve-year molars, erupt. This allows the orthodontist to place braces on all the permanent teeth, making it an ideal time for comprehensive orthodontic treatment.

Many of our younger patients undergo treatment concurrently with their peers, usually during middle school. This makes orthodontic treatment more socially acceptable and even exciting for them. Older patients, such as high school students, are often still interested in treatment but may express concerns that many of their peers have already completed their orthodontic journey.

Another factor to consider is the goal of completing treatment before your child leaves for college. Given that treatment may take 18 to 24 months, it's advisable to start orthodontic treatment no later than 16 years of age.

However, it's important to remember that it's never too late to achieve your best smile! Trust in our expert orthodontic care for optimal results at any age.

Regular dental check-ups are crucial for everyone, typically recommended twice a year for an exam and cleaning. However, during orthodontic treatment, it's advised to see your general dentist every four months or three times per year, as braces necessitate more rigorous cleaning.

Your general dentist plays a vital role in monitoring your oral health during orthodontic treatment, checking for cavities, gingivitis (gum inflammation), and ensuring you maintain proper dental hygiene. They also help prevent decalcification, which are white spots on your teeth due to poor hygiene and can be an early sign of future decay if not addressed promptly.

For patients with a history of periodontal disease undergoing orthodontic treatment, regular visits to the dentist or periodontist are essential. These patients are more susceptible to progressive periodontal disease during orthodontic treatment if they do not adhere to the proper cleaning protocol provided by their dentist/periodontist. This typically involves a rigorous cleaning regimen and regular follow-up visits to maintain the health of the gum tissue.

Good oral health also prevents your gums from becoming swollen or inflamed, which allows for more efficient orthodontic treatment. Maintaining good oral hygiene can also reduce bad breath and ensure you continue to flash a beautiful smile during your treatment. Trust in our expert orthodontic care for optimal oral health and a stunning smile.

If you're contemplating whether to opt for aligners or braces for your teeth straightening journey, here are some key points to help guide your decision.

Braces, a time-tested orthodontic solution with over a century of refinement, are engineered for precision. Each bracket is designed for a specific tooth, with a built-in prescription to move the tooth in three dimensions (torque, tip, and rotation). This prescription is based on extensive research aimed at achieving an ideal bite (occlusion) and a beautiful smile. Braces are available in metal or ceramic (clear) variants, with ceramic braces offering a more aesthetic appeal.

Aligner treatment, a more recent innovation in orthodontics, involves the use of molded plastic/resin aligners formed from precise impressions or digital scans of the teeth. The orthodontist creates a customized treatment plan based on this data, resulting in a series of aligners designed to gradually move your teeth. Attachments, a form of bonding, are placed on the teeth to enhance the effectiveness of the aligners. Aligners offer the advantages of being removable and clear. However, they are typically more costly and are better suited for less complex orthodontic issues, as they don't offer the same level of precision in tooth movement as braces.

In general, braces are a more cost-effective solution than aligners and often result in more predictable outcomes. Trust in our expert orthodontic care for the best treatment option tailored to your needs.

There's a prevalent misconception that you need a referral from your family dentist to schedule an orthodontic exam. While many of our patients come to us through dentist referrals, it's important to know that a referral is not a prerequisite. You can directly schedule your initial orthodontic consultation with Dr. Lewis. Start your journey towards a perfect smile with our expert orthodontic care today.

Orthodontic treatment is a powerful tool for correcting malocclusions (poor bites) and aligning crooked teeth. By improving both the function and aesthetics of your teeth, orthodontic care not only promotes better oral health but also gifts you with a stunning, attractive smile. This enhanced smile can boost your self-image and, in turn, elevate your self-confidence. Trust in our expert orthodontic care to guide you on your journey towards a healthier and more confident you.

Crowded, protruding, spaced, or misaligned teeth are clear indicators that orthodontic treatment could be beneficial. Other signs include an open bite, often associated with habits such as thumb sucking or tongue thrusting, where the front teeth don't meet when the mouth is closed. Less noticeable signs that may suggest the need for orthodontic care include mouth breathing, frequent cheek biting, a narrow smile, and a posterior crossbite. Trust in our expert orthodontic care to identify and address these issues, guiding you towards optimal oral health and a beautiful smile.

Unfortunately, the space available for teeth does not increase naturally after the eruption of the first molars around age 6 without orthodontic intervention. If teeth are crooked at this early age, the condition is likely to remain the same or even worsen as the individual grows older. Therefore, it's advisable to seek an orthodontic evaluation at an early stage. Trust in our expert orthodontic care to guide you towards a straighter, healthier smile.

Orthodontic treatment can be accomplished at any age so it is never too late to undergo orthodontic treatment. The fact is that about 25% of our patients at Masterpiece Smiles Orthodontics are in fact adults over the age of 25. We have many adults in their 60's and even early 70's. Remember, it is never too late to look your best, increase your self esteem/self confidence and improve your overall health.
