Orthodontist Services:

Unger Orthodontics offers a range of orthodontist services near you to improve patients' oral health and the appearance of their smile. Our treatments can resolve problems and issues related to misalignment involving the teeth or jaw.

Our services include:

Early treatment: Start building healthy dental habits with our early treatment option for kids. If your child has some baby and permanent teeth, they can get introduced to our team and receive a complimentary examination to catch any potential issues early on.
Orthodontics for teens: Teens need orthodontic options that fit their lifestyle. That's why we offer various options, ranging from clear Invisalign aligners to traditional braces, to meet their needs.
Orthodontics for adults: While we offer traditional metal braces for adults, we also have several other options like Invisalign to make straightening your teeth more comfortable and discreet.
Braces: Made out of durable metals like stainless steel, our silver-colored braces will transform your smile. For a more natural look, ask about our clear and champagne-colored brackets.
Aligners: Looking for a virtually invisible and removable solution? Our aligners offer an effective and affordable way to straighten teeth.
