Common Problems

Orthodontic problems can affect anyone – in fact, our teeth are almost never naturally perfect. Malocclusion, or a “bad bite”, can cause problems with chewing, oral hygiene, speaking and aesthetics. A bad bite can be genetic, or can be caused by thumb sucking, dental disease, poor dental hygiene, accidents, birth defects or other medical conditions.

Being educated about the orthodontic problem you or your child may have is the first step to correcting it. Orthodontic treatment performed by Dr. Nihar Tanna can improve both the functionality of your bite and the appearance of your smile.

Below are some examples of the most common orthodontic problems.

Upper Front Teeth Protrusion

The appearance and function of your teeth are impacted by this type of bite. It is characterized by the upper teeth extending too far forward or the lower teeth not extending far enough forward.


The upper front teeth extend out over the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth.


The upper teeth sit inside the lower teeth, which may cause tooth stratification and misaligned jaw growth.


Proper chewing is impacted by this type of bite, in which the upper and lower front teeth do not overlap. Openbite may cause a number of unwanted habits, such as tongue thrusting.


Crowding occurs when teeth have insufficient room to erupt from the gum. Crowding can often be corrected by expansion, and many times, tooth removal can be avoided.


Spacing problems may be caused by missing teeth, or they may only be a cosmetic or aesthetic issue.


In an underbite, the lower jaw extends out, causing the lower front teeth to sit in the front of the upper front teeth.

Orthodontics is a lot more than just straight teeth and a beautiful smile, we are focused on the overall long-term health of our patients. When a child presents with a crowded or crooked smile, this is a sign that the jaw is not growing properly. Certain oral habits and jaw deformities can lead to Obstructive Sleep Apnea (OSA) and Sleep Disordered Breathing (SDB).

Thumb Sucking

According to the American Dental Association, most children stop thumb sucking on their own between the ages of two and four. If the child continues past the age when their permanent teeth start to erupt, it may be time to take action to break the habit.  They may develop crooked teeth, crossbites, malformed roof of their mouth, and severe problems that affect jaw development resulting in overbites and anterior open bites. The severity of the problems depends upon the frequency, duration, intensity, and position of the finger in the child’s mouth. This can also affect the position of the upper and lower jaw resulting in speech impediments.
