Orthodontic Treatment Offered to West Covina Residents

Each treatment process is different from one patient to another because of your own aesthetic goals as well as what your anatomy will allow. Below are some of Dr. Guinn’s most popular & most sought after services:

Damon Braces

If you do not want to have orthodontic treatment that involved rubber bands, then you may want to ask Dr. Guinn about self-ligating Damon braces.


Dr. Guinn’s favorite course of treatment is traditional braces. She believes this is the option with the highest value and return. For years she has been able to transform smiles with braces West Covina patients can depend on.

TMJ Treatment

Do you or a loved one exhibit severe teeth grinding while sleeping?

Ask Dr. Guinn about her TMJ treatment if you or a loved one is affected by temporomandibular joint disorder.
