Clear Aligners

The Coreil Clear experience begins with a Virtual Consultation where you provide images of your teeth to Dr. Coreil for evaluation…without having to leave the comfort of your home. This allows you to find out about treatment options, price and time needed to address your concerns. The details can be discussed over the phone or oven better we can meet live via Zoom. This gives you the opportunity to get a personalized plan, ask questions about the possibility of needing clear dental aligners and knowing an experienced orthodontic specialist is taking care of you.

Benefits of Clear Aligners:

More Clear BPA Free Stains Less Faster Treatment More Comfortable

Sleep Apnea Treatment

Sleep apnea can affect both children and adults with men over 40 at the highest risk. Over 22 million Americans suffer from sleep apnea and many remain undiagnosed. When left untreated sleep apnea can lead to high blood pressure, chronic heart failure, stroke, and depression. It is a factor in many accidents as a result of drowsiness from a lack of sleep.

TMJ Treatment

Facial pain and headaches are often associated with bite problems. The first step in our treatment approach is to alleviate pain using very conservative measures such as wearing a splint to stabilize the bite along with physical therapy and exercise. Once pain free we will determine what is needed to maintain the overall improvement.
