What is a Cosmetic Dentist?

With a skilled cosmetic dentist, the smile you’ve always dreamed of can become a reality. While cosmetic dentists principally seek to enhance your smile’s appearance, they are driven by an overarching goal of creating positive changes to your confidence and self-esteem. Those trained in this special branch of dentistry aim to optimize the long-term aesthetic of your teeth and gums using advanced approaches designed to benefit your oral and overall health. In addition to restoring a full and healthy tooth structure, a cosmetic dentist also works to enhance proper jaw alignment and biting function. From simple smile rejuvenation with Invisalign® or porcelain veneers to more complex concerns involving TMJ Disorder treatment, bone loss, or full mouth rehabilitation, cosmetic dentists are committed to furthering your smile and oral wellness by providing a compassionate and comfortable experience for all of your treatment goals.

How to Select the Best Dentist for You

Choosing the right dentist for your needs is pivotal to receiving high quality treatment and exceptional results. The following tips can help you navigate who to entrust with your oral care:

  • Research Credentials: Whether you are interested in a cosmetic procedure, routine check-up, or restorative solution, you want to be sure your dentist is well-established and experienced in your chosen treatment. Take a look at your prospective dentist’s biography and find out where they’ve received training, their memberships and affiliations, and whether they’ve been honored with any awards or recognitions.
  • Take a Look at Before-and-After Photos: A patient showroom or smile gallery is usually an excellent indication of the treatment results you can expect to receive. Try to find before-and-after photos of a patient whose dental concerns are similar to yours. This can be a great way to determine whether the final outcome of a given procedure is able to meet your expectations.
  • Learn About the Practice’s Technology: The equipment and technology utilized by a practice can speak volumes about their ability to provide advanced dental treatment with the latest, most effective techniques. Key features that can enhance your experience may include sedation dentistry options or minimally invasive treatment protocols.
  • Read Testimonials and Patient Reviews: There’s often no better way of gleaning an idea of your potential patient experience than by perusing through the reviews of those who have already received treatment. While testimonials are usually compiled on a practice’s website, third-party reviewing platforms can provide additional insight from a diverse range of patients about the care you can expect to receive.
