Even though I was a bit miffed at the wait time, Dr. Sirin received my feedback positively and did not let it degrade the service and attention she gave to me. She worked diligently to address the key reasons I had booked an appointment with her and completed the work quite well and I was able to get to my next meeting on time.

Dr. Ocharoen and her staff are professional and personable. I’ve been a patient of Dr. O’s for about 5 years. Whenever I’ve had an issue or an “achy tooth,” the staff makes every effort to accommodate me and get me in, to address the problem or advise me by phone, as soon as possible. I highly recommend this practice!

Dr. Ocharoen is an outstanding dentist. She and her entire staff are always welcoming and friendly. They’re also very professional and you know you’re in good hands. I recently started Invisalign with them and the entire process could not have been better. I highly recommend their services if you’re looking for great dental care.

Return patient! I moved away 2 years ago and went back to my old dentist because they were 1 mile away. HOWEVER I was not happy, so I drove 15 miles to Sirinity Smiles today because I have always had a great experience here. The office team is very professional. Doctor Ocharoen is knowledgeable, and has excellent communication skills She is thorough when reading my xrays explaining what is going on with my teeth and what she can do. Today Lois assisted with my cap. She was very friendly and upbeat.Perfect personality for a dental assistant. I highly recommend this business.

I’m BLOWN AWAY with my results!! My teeth were so bad and now I’m done with treatment! So happy! The staff were amazing all along my journey! I could even call if I had concerns and they would help or fit me in again. Dr.O really listens and delivers above and beyond! At my last visit I was being very picky with the filing of some teeth and she was patient and honest and attentive to what I wanted and I couldn’t be happier!! SO grateful I found this place & now I have a great smile!! Thank you Dr.O!!! 🫶🏼😁

Platinum Invisalign Treatment iN FLORHAM PARK, NJ

We're Experienced with Invisalign

We recommend Invisalign teeth aligners to adults and teens who want to gradually straighten their teeth, but don’t want to endure the inconvenience of traditional metal braces. Are you a candidate for Invisalign? Call to schedule a consultation or use the online booking feature to find out why we are a Platinum Provider.

Platinum Invisalign Provider endorsement.
American Academy of Clear Aligners logo.

Invisalign is a treatment that uses clear aligner trays to gently move teeth into place. The trays are worn in a series over time to create a beautiful smile. Invisalign is a popular alternative to traditional braces, and does not have any brackets or wires. The Invisalign trays are discrete and are comfortable when worn, and do not cause gum or mouth irritation.

Invisalign is a popular choice for both teens and adults. This treatment helps if you have overcrowding, chewing, or overbite issues. Older teens and adults can follow the instructions daily and ensure the trays are worn for the required amount of time. On average Invisalign treatment takes between 6-18 months which is comparable to the treatment time for traditional braces.
