Straighter teeth perform chewing, biting, speaking and airway functions more effectively than crooked teeth. In addition, a straight smile boosts confidence, is aesthetically pleasing to look at, and can help prevent a wide variety of dental ailments (see below).
There are several types of malocclusion including overbite, underbite, crossbite, and overcrowding. Each of these alignment problems negatively impacts the functionality and cosmetic appearance of the teeth.
Here is a brief overview of some of the main disorders associated with crooked teeth:
Periodontitis – Periodontitis or gum disease begins with a bacterial infection. The bacterial infection is caused by inadequate oral hygiene. Crooked teeth are hard to effectively clean, which means that debris, plaque, and bacteria can build up in hard-to-reach areas. Adults experiencing gum disease may have their heart health negatively affected by it, in addition to possibly losing their teeth through such infections. Straight teeth are much easier to clean and are at less risk of contracting gum disease.
Temporomandibular Disorder (TMJ) - Crooked teeth can lead to improper jaw alignment, which in turn causes a painful condition known as TMJ. Severe headaches, jaw pain, lockjaw, and grinding of teeth characterize this debilitating disorder.
Constricted Airway function, or Sleep Apnea - Common but harmful behaviors like mouth-breathing, tongue-thrust, thumb-sucking… not only lead to narrow and collapsed palates and crowded teeth but also directly affect the space, size, and shape of the nasal cavity. This leads to constricted and narrow nasal cavities which make breathing through your nose more difficult. This compromised airway effects EVERYTHING from daytime cognitive performance (ADD / ADHD) to nighttime sleep quality (sleep apnea), because the body cannot properly oxygenate the organs. Daytime sleepiness, fatigue, headaches, poor school performance, general nervousness, snoring and grinding of teeth characterize different symptoms of airway dysfunction.
If a narrow upper jaw develops due to harmful habits or mal-development, it traps the lower jaw from growing - think of the lower jaw as a car trying to move forward into a garage [as the upper jaw] which has narrow, constricted walls —it can’t move forward in this case. If the lower jaw, or mandible is trapped or blocked from achieving its natural forward growth, this constricts the wind pipe and air-flow behind it. You can now understand how a healthy airway is the foundation of ideal orthodontic treatment results and why addressing all the CAUSES, not just addressing the teeth, is important to your child’s smile AND general health.
Tooth injury – Straight teeth create a strong wall, which means injuries are less likely to occur. Crooked teeth are weaker and often protrude, making them far more vulnerable to external injury.
Uneven wear – Crooked teeth cause some of the teeth to work harder than others when biting and chewing. Straight teeth share the workload evenly, meaning less risk of injury and better aesthetics.
Teeth can be straightened using either orthodontic braces or customized aligning trays. Orthodontic braces are usually affixed to the teeth for a set duration. The brackets and archwires are tightened regularly by the orthodontist and removed when treatment is complete. Fixed braces can be placed on the front side or back side of the teeth and are effective for most types of malocclusion.
Aligning trays are fully removable and are used where the malocclusion is less severe, and the teeth need to move a shorter distance. These trays are replaced every few weeks for the duration of the treatment, and have proven to be equally effective for straightening teeth.
