We recognize that every patient is different, and we strive to treat you as the unique individual you are by creating personalized treatment plans tailored to meet your specific needs and desires. We offer the latest types of braces, including:

Invisalign is the ideal solution for adult patients looking to enhance their smile, but are concerned about the appearance of traditional braces. Using a series of clear, removable aligners, Invisalign works hard to correct your smile and twice as hard to keep others from noticing.

Invisalign Teen
We also have Invisalign Teen, which allows mature teens to perfect their smile using clear aligners so their teenage memories can be captured with confidence. Invisalign Teen has been specially designed with your teen’s busy schedule in mind and uses blue-to-clear color-changing aligners to keep their treatment on track!

Whether you or your child needs orthodontic braces, Dr. Penna and his team are experienced in providing you with the results you expect! Schedule a consultation with us today to begin your journey to a beautiful, confident smile. We look forward to seeing you smile!
