Spaces and gaps between teeth can be closed for an improved smile.

Crowding and crooked teeth may be harder to clean, leading to increased chance of cavities and gum disease.

Teeth may have a large "overjet", where one may feel their teeth stick out too much. It may be hard to close the lips together comfortably because of the flared teeth.

A deep bite is when there is too much overlap of your front teeth. Overtime, this may lead to heavy wear on your lower incisors' edges.

An open bite is when the front teeth do not contact when you are biting down. This may lead to difficulty biting through food and may cause a speech impediment. Habits such as thumb/finger sucking or tongue thrust may cause an open bite.

An underbite is when your lower teeth sit in front of your upper teeth. This is often caused when your lower jaw outgrows your upper jaw and is commonly genetic.

When your front upper and lower teeth edges sit on top of each other. Heavy wear of those teeth can occur over time.

If a tooth has been missing for a long period of time, the teeth around it may shift and actually tip over. This makes it much more difficult to replace a missing tooth with an implant or bridge. Also, a tipped tooth can lead to gum problems because it is harder to care for.

An “impacted” tooth is a tooth that either has not come in (“erupted”) when expected or a tooth that cannot erupt because it does not have room or may be coming in the wrong direction or position.
