Types of Bites

Types of Bites in Hamilton (Jackson Square), Burlington, Cambridge and St. Catharines!

There are a variety of orthondontic disorders that we can help treat here at Martindale Dental and we’ll discuss these in more detail now, but encourage you to call one of our offices to schedule a consultation if you need help treating any of these disorders.


A crossbite is an orthodontic disorder that can take place in either the front or sides of the mouth, or both. A person will have one or more upper teeth that will bite down on the inside of their lower teeth when a crossbite is present. We recommend early correction to avoid:

  • Gum disease
  • Bone loss
  • Premature wear of teeth
  • Improper chewing patterns
  • Asymmetrical jaw development
  • Relation to jaw joint dysfunction (TMJ)

Correcting a Crossbite

The way in which we can help you correct a crossbite depends on how many teeth are affected. If it is just a single tooth crossbite we can use braces to correct the positioning of teeth. There have even been times when a retainer was enough to correct the problem. However, if multiple teeth are affected you will need to have the arch expanded using braces and/or other oral appliances.


openbiteIf you have an openbite it means your teeth insufficiently overlap vertically. Different oral habits can cause this problem including thumb (or digit) sucking, uneven jaw growth and tongue thrust. The success of correcting an openbite depends on the timing of treatment.

Openbite should be corrected because it can:

  • Cause premature wear of the back teeth
  • Cause dysfunctional chewing patterns
  • Make your smile less attractive
  • Be related of jaw joint dysfunction (TMJ)

Correcting an Openbite

Our professional team will assess your openbite and determine the best method for correction. This might include anterior or front teeth extrusion, braces, or some times, surgical means to correct the jaw. Of course, any oral habits present need to be overcome as well including thumb sucking, to completely correct an openbite.

overbiteWhen an overbite is present the upper front teeth will protrude over the front lower teeth with practically no contact between upper and lower front teeth. This particular bite occurs when an uneven amount of front teeth eruption has taken place, or the bone supporting the teeth has been over-developed. You might hear this kind of bite also referred to as a deep bite. We encourage having an overbite corrected to avoid

  • Unusual wearing of front lower teeth
  • Inadequate functioning of front teeth
  • Possible front lower teeth biting into upper gum tissue
  • Less attractive smile

Correcting an Overbite

Our professional team can help you correct an overbite by moving the front teeth or ensuring the back teeth come back together to ‘open’ the bite, properly aligning the teeth and eliminating the overbite.


overjetYou may not have heard this term used often but it’s also known as protrusion. An overjet bite means your lower teeth are farther behind your upper teeth. This can be caused by flared upper incisors, misalignment of molars, missing lower teeth or a mixture of these factors. And again, thumb sucking or tongue thrusting can also worsen an overjet. We highly advise you correct an overjet bite to avoid:

  • Improper front teeth function
  • Premature wearing of teeth

We can help you correct this bite via an appliance and/or elastics.


underbite Many people are aware of what an underbite is and what it looks like. However, living with an underbite can be very troublesome. The lower teeth will protrude past the front teeth when an underbite is present. The lack of growth to the upper jaw can cause underbite as well as too much growth of the lower jaw, lack of lower teeth, flared upper incisors or a combination of any of these factors. We advise having an underbite corrected early on to avoid:

  • Jaw or joint problems
  • Improper function of front teeth or molars (TMJ)
  • Premature wearing of teeth
  • Eating or chewing problems
