What causes misaligned teeth? Our ancestors' jaws were much larger, which made for a more ideal bite – or occlusion. There used to be more space in the mouth with plenty of room for the teeth, including the wisdom teeth. But due to dietary and genetic changes, jaw sizes have shrunk over time and today, one in five people have some sort of malocclusion where their teeth don't line up correctly, according to Science Daily. Some misalignments are minor and do not need correcting, but many cases require a referral to a specialist in order to achieve the perfect smile.
Malocclusion: Getting The Bite Right
The term refers to any type of irregular contact between the upper and lower teeth. It can manifest as an overbite, open bite, under bite or cross bite. Your dentist will evaluate your occlusion at your dental visits and make recommendations for treatment, if necessary. Proper alignment allows for effective chewing and distribution of biting forces equally over all the teeth. If this balance is not ideal, over time malocclusion can lead to broken teeth and even tooth loss. There are several causes of malocclusion, including:
- Mismatch between jaw size and size of teeth
- Thumb sucking or tongue thrusting habit
- Premature or congenital loss of or missing teeth
In most instances, treatment involves orthodontics, including options like braces. Braces are usually used in childhood or early adolescence when the jaws are still developing and growing. However, it is never too late to seek treatment and orthodontists are trained to treat both children and adults. Treatment is often in phases and sometimes requires extraction of baby or even permanent teeth. In very rare cases, surgery may be necessary, especially in Class III instances. This orthognathic procedure is done by a maxillofacial surgeon to shorten the lower jaw to allow proper alignment of the teeth.
Throughout any type of treatment, proper care of the teeth and mouth, like brushing and flossing, are required for the best results. With braces, brackets are attached (bonded) to the teeth, and wires and elastics are connected to the brackets to correct alignments. These additions to your smile, however, can create significant challenges to keeping the teeth clean and healthy. Your dentist or orthodontist will recommend a fluoride treatment, like Colgate® Gel-Kam Preventative Treatment Gel, to help fight decay and decalcification.
Regular visits to your dentist and dental hygienist will help you diagnose any upcoming occlusion problems with your teeth and other underlying habits that will interfere with a healthy smile. And even if you're an adult, it's never too late to address the issue of an improper bite. Dentists and orthodontists are trained to give you a beautiful, healthy smile at any age.
