Metal & Ceramic Braces

Braces are a dependable way to correct alignment and create a balanced, healthy smile. With today’s smaller, smoother designs, treatment is more comfortable and effective than ever. Braces gently guide teeth into better positions, helping patients of all ages achieve consistent, long-lasting results with precision and control.

Invisalign Clear Aligners

Invisalign® offers a clear, flexible alternative to traditional braces. These custom aligners fit comfortably and blend seamlessly into your daily routine. Designed for convenience and subtlety, Invisalign gradually shifts your teeth while allowing you to eat, brush, and live freely without brackets or wires getting in the way.

Wonderful place, typically not a fan of any dentist or orthodontist but Dr. Samantha Cardinal changed that. She was able to make me retainers in a quick and comfortable manner. Highly recommend.

This office is wonderful, they really make you feel comfortable here! Super friendly staff and Dr. Samantha is the best orthodontist I’ve ever been seen by! Highly recommend this place for any of your ortho needs, wish I could give 10 stars!
I’m a new patient and came in to get some retainers made for me and the staff was so kind and welcoming. I was in and out and the entire process was done in less than fifteen minutes! In the past with other orthodontists I have had to get impressions made which is uncomfortable and takes a long time. With Coastal Smiles they simply and gently scanned my smile and had me in and out the door! Samantha Zavada Cardinal always has a smile on her face and is amazing with her patients. The entire staff were sweet, complimentary, and fast! I cannot recommend this establishment enough!!

I am very pleased with my results at coastal smiles. Dr. Cardinal listened to what my concerns were, and my appointments were always quick and easy. All of the assistants were also so friendly every time I came in! As an adult, I didn't want metal in my mouth, so she found me a solution with Invisalign I'm really happy with. Thank you Dr. Cardinal for being such a caring and kind doctor!
