What a wonderful dental practice! I’ve never received such amazing and personal care at a dentist office and/or most other medical offices. This team works well together and is happy to let you know as many details as you’re interested in knowing about what’s going on in your mouth. Everyone is on the ball, responsive, and just a pleasure to chat with! I rarely post reviews and found myself asking where I can do so for this office due to the high level of service I received. Thank you everyone and I look forward to my next cleaning ;)

Did You Know Orthodontics Can Also
Improve Your Oral Health?


While most people undergo orthodontics to fix cosmetic concerns, treatment can also improve your oral health. When your teeth are evenly spaced, you can brush and floss more thoroughly and prevent tooth decay. Furthermore, clear aligners will properly align your bite, helping you avoid serious and painful jaw conditions.

Am I a Candidate for Invisalign?

Teen with invisalign

Invisalign works well for the majority of our New Haven patients with mild to moderate dental misalignment. While traditional braces might still be the best option for severe cases, aligners can address most types of orthodontic concerns. Despite some common misconceptions, there is no age requirement for Invisalign and you are never too old to undergo treatment. As long as you have all your adult teeth and are responsible enough to wear the aligners, your age is not important. In fact, Invisalign can be a safer treatment option for younger patients who are active in sports and could sustain trauma from braces.

The best way to find out if you qualify for Invisalign is to schedule a consultation with Dr. Lerch.

What to Expect During Treatment

Take a look at the steps involved in your Invisalign treatment at our New Haven, CT, dental practice.

If you wear your retainer as instructed, your results can last the rest of your life.

Day of Procedure

If you wear your retainer as instructed, your results can last the rest of your life.


After we examine your teeth during your consultation, Dr. Lerch will design your custom Invisalign system. We take precise impressions of your bite and send them to the lab that produces your personalized clear aligners. When they are ready, you will return to the office for detailed instructions and your first set of aligner trays.


Wear your aligners for at least 22 hours a day, taking them off as needed to eat, drink liquids other than water, and brush your teeth. Each aligner is used for approximately two weeks and then switched out for the next in the series. The trays apply gentle pressure on your dental arches and gradually shift the alignment of your teeth and bite. Every 6-8 weeks you will come in for a checkup to ensure your results are progressing as intended.


Your treatment is complete once you finish with the last aligner in your series. After, you will no longer need to wear your trays during the day. Dr. Lerch will provide you with a retainer to continue wearing at night. If you wear your retainer as instructed, your results can last the rest of your life.

Looking for the Same Dramatic Transformation?

If you have several cosmetic concerns you wish to address, you may want to consider a smile makeover. A smile makeover combines multiple forms of cosmetic and restorative dentistry into one streamlined procedure. Dr. Lerch will sit down with you to discuss your goals and customize your treatment to reach them there. Straightening your teeth with Invisalign is usually a great first step. Once your teeth are properly aligned, we can use whitening, veneers, bonding, and more can take your results to the next level. The finished product will be a picture-perfect smile.

The best dentists office I’ve been to in years. I saw dental hygienist, Dung (pronounced young) at the beginning of the week. She was so kind and explained everything that she saw in my ex-rays. Gave me tips on flossing and other things. Today I received a filling and Dr. Lurch was just as lovely and thorough. 10/10 would recommend.

Definitely one of my best dentist experiences. Dr. Dung is very knowledgeable and made sure that I was comfortable throughout the entire process. She also taught me a lot about taking care of my oral health and broke down the applicable anatomy. Highly suggest this office for anyone looking for a new dentist.
