The American Academy of Pediatric Dentistry recommends children visit the dentist by their first birthday. It is crucial that your child’s newly erupted teeth receive appropriate dental care right from the beginning, and benefit from proper dental habits through childhood and into adulthood.  


The American Association of Orthodontists recommends that an orthodontist can evaluate children as as early as age 7, even before all permanent teeth are present.  Early orthodontic treatment may consist of palatal expanders, early braces, space maintainers and growth monitoring.


The early pre-teen to teen years are a great time to start full braces or Invisalign since all permanent teeth are present.  Some patients may have already had a previous phase of treatment (Phase 1) and are ready for Phase 2, or some patients may just be starting treatment for the first time.


More adults are seeking orthodontic treatment now than ever before with Invisalign or braces.  There are more cosmetic options available currently than in the past, and many of Dr. Nima's patients are adults of all ages.


Dr. Nima Rohani is a top Invisalign provider and an expert in improving smiles with Invisalign. Using a system of clear, computer generated aligners that are custom made, this is a more esthetic option that many teens and adults prefer. Invisalign straightens teeth gradually without the use of visible brackets.  One major advantage of Invisalign is that these aligners are removable, allowing patients freedom in what to eat and drink, as well as improved oral hygiene since brushing and flossing is much easier than it is with braces.


Board Certified Orthodontist Dr. Nima Rohani leads the Top Smile team in providing attentive, ethical and comprehensive care. 

Board Certified Pediatric Dentists Dr. Yasi Yazhari & Dr. Mikael Garces care for all the young smiles at Top Smile. 

Rather than just being general dentists, our doctors are specialists, meaning that they have further, expert training beyond dental school.
