Orthodontics is more than a nice smile. Every patient’s bite and alignment needs are different. Orthodontic treatment addresses far more than appearance, it supports healthy function, comfortable chewing, and long-term oral health, for both children and adults. Whether you or your child is dealing with crowded teeth, a bite concern, or a jaw alignment issue, our personalized treatment plans are built around what your smile actually needs.
Below is an overview of the orthodontic conditions we most commonly treat and how we approach each one.
Free ConsultCrowding occurs when there is not enough space in the jaw for all the teeth to fit properly, causing them to overlap, rotate, or sit out of alignment.
Why it matters:
How we treat it: We use braces or clear aligners, Angel Aligner or Invisalign, to gently guide crowded teeth into proper alignment. In growing children, early treatment or a palatal expander can create additional space and often reduces the need for more extensive treatment later.
Learn More Free ConsultSpacing, or gaps between the teeth, can result from genetics, missing teeth, or habits such as thumb-sucking.
Why it matters:
How we treat it: Using braces or clear aligners, or Invisalign, we close gaps and bring the teeth into a well-balanced, even alignment.
Learn More Free ConsultA posterior crossbite occurs when the upper back teeth sit inside the lower back teeth, on one or both sides of the jaw.
Why it matters:
How we treat it: Traditional rapid palatal expanders or Invisalign palatal expanders or Angel Kid aligners are typically used to widen the upper jaw and restore proper alignment between the upper and lower back teeth.
Learn More Free ConsultAn anterior crossbite occurs when one or more upper front teeth sit behind the lower front teeth, sometimes described as a front-tooth underbite.
Why it matters:
How we treat it: Treatment often involves clear aligners, or Invisalign and sometimes early intervention in growing children to correct the alignment before it affects jaw development.
Learn More Free ConsultExcess overjet, often called an overbite, occurs when the upper front teeth extend significantly beyond the lower front teeth.
Why it matters:
How we treat it: Clear aligners, Invisalign, or growth modification appliances bring the upper and lower teeth into better alignment, reducing excess overjet over the course of treatment.
Learn More Free ConsultA deep bite occurs when the upper front teeth overlap the lower front teeth excessively, sometimes covering them almost completely.
Why it matters:
How we treat it: Braces or clear aligners or Invisalign help create a more balanced bite, to gradually adjust bite depth.
Learn More Free ConsultAn open bite occurs when the upper front teeth and lower front don’t touch, and only the back teeth are touching. There is a space between the front teeth. An open bite can sometimes be the result of thumb sucking or prolonged pacifier use.
Why it matters:
How we treat it: Clear aligners or Invisalign help the front teeth start to touch by slowly moving the back teeth into the bone. In very severe cases, mini-implants or orthognathic surgery are used to correct the open bite in adults.
Learn More Free ConsultAn uncomfortable bite occurs when the upper and lower teeth do not come together properly, making chewing or biting difficult.
Why it matters:
How we treat it: We use braces or aligners to align the teeth and jaws, working toward a bite that is both functional and comfortable.
Free ConsultAn underbite occurs when the lower jaw extends forward, causing the lower front teeth to sit in front of the upper front teeth.
Why it matters:
How we treat it: Treatment often involves braces, clear aligners, or appliances that guide jaw growth in younger patients. In more severe or skeletal cases in older teens or adults, surgical orthodontics may be considered.
Free ConsultOrthodontic treatment is not limited to the teeth. It can also influence the overall balance of facial features, including a recessed chin, prominent jaw, or uneven lip position.
Why it matters:
How we treat it: Using advanced orthodontic techniques, we can help guide jaw growth, adjust the bite, and support better facial harmony, particularly when treatment begins early. In adult patients, fully correcting jaw size differences happens with orthognathic surgery
