Clear braces are made of ceramic material and are, therefore, less visible on your teeth than metal braces yet are also available with colored elastics.
Clear aligners are a series of invisible, removable, acrylic trays that straighten your teeth like braces. Aligners are tight when initially inserted and become more comfortable with extended wear.
Traditional metal braces are the most common type of braces and are more comfortable today than ever before. Made of high-grade stainless steel, metal braces straighten your teeth using metal brackets and archwires.

"As an adult I found myself needing braces. I inquired with friends to find a good orthodontist, and I received consistently positive recommendations for Dr. Michelle Cartier...in fact no other orthodontist was even mentioned. I scheduled a (free) consultation with her, after which I felt completely confident that she could correct the problems I was having. The results were fantastic. I am very happy I did it. The atmosphere of Dr. Cartier’s office is personable yet professional, and her effervescent personality made my orthodontic experience actually enjoyable. Since that time she has seen both of my children and given them beautiful smiles too."
- Abigail S.

Treatment costs vary depending on the complexity of your case. Braces typically range from $3,000–$7,000, and Invisalign falls within a similar range. At Cartier Orthodontics, we offer flexible payment plans with low monthly options to make treatment affordable. We also verify your insurance benefits for free before you commit to anything. Your complimentary consultation includes a full cost breakdown with no hidden fees — so you know exactly what to expect before you start.
Yes. Your initial orthodontic consultation with Dr. Cartier is completely complimentary. It includes a clinical exam, a discussion of your concerns and goals, a review of treatment options (braces, Invisalign, clear braces, or airway orthodontics), and a clear explanation of costs, insurance, and payment plans. There is no obligation and no pressure to start treatment. We believe you deserve all the information before making a decision.
Most patients feel mild pressure for the first 3–5 days after braces are placed or after each Invisalign tray change. This is normal and means the treatment is working. Modern braces and clear aligners are gentler than ever — most kids and teens adjust within a few days and don't need anything beyond over-the-counter pain relief. 92% of orthodontic patients say they would do it again. Dr. Cartier walks every patient through what to expect so there are no surprises.
The best way to find out is a professional evaluation. The American Association of Orthodontists recommends children see an orthodontist by age 7. During your free consultation, Dr. Cartier will assess your child's teeth, jaw development, and breathing patterns to recommend the right treatment — whether that's metal braces, clear braces, Invisalign, a palate expander, or airway-focused care. If treatment isn't needed yet, we'll tell you that honestly and monitor their growth at no charge.
Airway orthodontics focuses on how the development of the jaw, teeth, and airway impacts breathing, sleep, and overall health. If your child snores, breathes through their mouth, sleeps restlessly, has trouble focusing at school, or shows signs of chronic tiredness, these could be signs of an airway issue. Dr. Cartier works closely with an onsite ENT specialist to evaluate and treat these concerns as part of a comprehensive care plan. Early intervention — ideally between ages 7 and 12 — can prevent more complex treatment later and improve your child's quality of life.
Yes. We accept most major dental insurance plans that include orthodontic coverage. Our team will verify your benefits and process your claims so you get the maximum coverage available. Many plans cover 25–50% of orthodontic treatment. For any remaining balance, we offer low monthly payment plans and financing options to keep treatment affordable. We handle the insurance paperwork — you focus on your smile.
Treatment duration depends on the type and complexity of your case. Most braces treatments take 12–24 months. Invisalign typically ranges from 6–18 months for mild to moderate cases. Early treatment or palate expansion for children usually takes 6–12 months. During your free consultation, Dr. Cartier will give you a realistic timeline specific to your case. She has over 30 years of experience and is board certified by the American Board of Orthodontics — so your treatment plan is built on precision, not guesswork.
