Common Problems

One of the greatest benefits of being evaluated by board-certified orthodontist Dr. Sam Kadan is learning that you have one of the common problems that are treated with orthodontic treatments. The insight gives hope to many adults, teenagers, and parents in the Bucks County and Philadelphia area.

Who Can Benefit from Orthodontic Treatment?

The field of orthodontics has evolved, and now treatments are proven effective for children, teenagers and adults alike. Problems that were once considered challenging or impossible can now be addressed with an array of interventions. The most common problems that Dr. Kadan treats are:

  • Thumb sucking
  • Underbites
  • Spacing
  • Upper front teeth protrusion
  • Crowding
  • Crossbites
  • Overbites
  • Open bites
  • Dental midlines that are not matched

Even if you have orthodontic issues that are not considered common, Dr. Kadan has the professional expertise you need to have a healthy, attractive smile.

Thumb Sucking

Thumb sucking is not necessarily an issue in young children, but if the habit continues, it can have a significant impact on jaw and tooth development. Thumb sucking applies pressure to developing teeth and jaw bones that can become permanent, such as:

  • Protruding front teeth
  • Openbites
  • Lower front teeth that have a backward alignment
  • Crossbites

Orthodontic treatment will correct these problems and allow the teeth and jaw to develop properly.


When the lower jaw is further out than the upper jaw, the condition is referred to as an underbite. Braces modify jaw development to enhance proper alignment between the upper and lower jaw.


Inconsistent development between the jaw and teeth may result in having gaps and spaces between the front and back teeth. The teeth may be smaller in comparison to the other teeth, or the shape of the teeth may be an issue.

Protrusion of Upper Front Teeth

Protrusion refers to front teeth that extend outward more than the lower front teeth. The problem may be caused by either upper teeth that stick out or lower teeth that are inwardly aligned. Protrusion of the upper front teeth increases the likelihood of injury to the mouth and teeth, as well as affecting aesthetics and bite pattern.


Crowding is the most common problem amongst adults who undergo orthodontic treatment. The condition occurs when the erupting teeth do not have adequate space and must shift position either by rotating or growing outside the natural tooth line. Conditions that lend to overcrowding are:

  • Inconsistencies between the size of the teeth and space on the jaw bone
  • Impacted teeth that do not erupt vertically
  • Baby teeth that do not fall out as the adult tooth emerges
  • Crossbites

The two options that correct overcrowding are tooth extraction and expanders.


A crossbite develops when the lower jaw is too wide, or the upper jaw is too narrow. If the condition affects the upper jaw, the patient must move the lower jaw either forward or sideways in order to achieve a stable bite. Dr. Kadan categorizes crossbites as either unilateral (affecting one side of the jaw) or bilateral (affecting both sides of the jaw).


Having an overbite means that there is a significant overlap of the upper front teeth over the front lower teeth. The condition places undue pressure on the incisor teeth and leads to misalignment.

Open Bite

Open bites occur in either the front or back set of teeth, and the condition is categorized as anterior or posterior. An anterior open bite refers to upper front teeth that do not properly overlap the lower front teeth. A patient is diagnosed with a posterior open bite when the back teeth are not properly aligned. The most common causes of open bites are thumb sucking, jaw abnormalities and tongue thrusting in which the patient presses the tongue against the teeth.

Dental Midlines Not Matched

One of the indications of proper tooth and jaw alignment is a matched dental midline. If the midlines are not matched, the patient has a backbite that is not aligned. The condition has negative implications on dental function and the jaw joint.

How Much Does Orthodontic Treatment Cost in Bucks County and Philadelphia?

If you or your child are one of the many people in the Bucks County and Montgomery County area who has been diagnosed with orthodontic issues, Dr. Kadan invites you to schedule a personal consultation with him. As a board-certified orthodontist, he is able to quickly diagnose the common problems with jaw and tooth alignment, as well as problems that are rare and unusual. After your consultation, we will discuss the cost of your treatment.

Payment can be made by:

  • Cash, personal check and credit card
  • Financing through CareCredit®
  • In-house financing options

We are an in-network provider for many of today’s top dental insurance companies. Using an orthodontist that is in your dental care network benefits you by:

  • Providing lower out-of-pocket expenses
  • Saving you time and money by completing and filing all necessary claim forms at no extra charge to you
  • Accepting the payment we negotiate with the insurance company as payment in full
  • Never sending you a bill for the charges that are above the negotiated rate, known as balance billing
  • Expecting you to only pay your applicable co-payment, deductible and co-insurance according to the terms of your policy
  • Letting you pay only for your portion rather than expecting you to pay the full cost and get reimbursed by the insurance company

What to Expect During Your Consultation

The consultation that you have with Dr. Kadan includes a complete examination, X-rays and imaging with the iTero® Element™ system that creates a three-dimensional model of your teeth and jaw. Based on his findings, Dr. Kadan decides on the orthodontic treatments that will improve jaw and teeth alignment. Your treatment plan may include orthognathic surgery, braces, and other orthodontic appliances.
