What Causes Misaligned Midline Teeth?
Midline misalignment is a relatively common condition among adult patients. The condition involves asymmetrical center points in the upper and/or lower jaw. Other terms used to describe midline misalignment include a dental midline shift and deviated midline.
This condition is common and there are treatment options which can be used to restore the symmetry of the teeth. It is quite rare for patients to experience complications and most of the treatments are not overly invasive. A summary of the causes and treatments available for a misaligned midline is below.
Causes
Certain medical conditions and lifestyle habits can both cause midline misalignment. Some of the most common for the condition are summarized below.
Missing Teeth
Hypodontia describes patients who are actually missing one or more of their adult teeth. Causes for missing teeth may include issues like gum disease, decay, accidents, and some patients are simply born without the teeth. The lack of a tooth results in a gap, which can allow for the other teeth to shift into the open space, ultimately resulting in a misaligned midline.
Crowded Teeth
The midline may also be impacted by overcrowding in the mouth. The teeth may erupt abnormally or simply fail to be properly spaced. This is especially common when the patient has a small jaw or does not have enough room in their mouth to properly fit their teeth.
Jaw Misalignment
Bite issues such as a crossbite, open bite, or underbite are all types of a misaligned jaw. These problems can cause a malocclusion of the teeth, where the teeth do not fit together properly. This often results in a midline shift as well.
Lifestyle Habits
Certain habits such as a child sucking their thumb or using a pacifier well into toddlerhood can result in various orthodontic problems. Midline misalignment is common for these types of patients. It is important for parents to be diligent in monitoring pacifier use or sucking of the thumb. These habits can unfortunately result in long-term consequences when they are not regulated.
Treatments
If the patient is concerned that they have midline misalignment, it is important to follow up with a dentist or orthodontist. The dental professional can evaluate the patient and review their treatment options. Below are common treatment options used to correct a misaligned midline.
Braces
Braces have been in use for decades and are an excellent solution for treating various dental misalignments. They are highly effective in the treatment of a misaligned midline. Braces can resolve the issue at the skeletal level. This orthodontic treatment is highly effective in correcting various orthodontic issues and helping patients achieve a beautiful smile.
Invisalign
Another popular solution used to treat minor cases of a misaligned midline is Invisalign. Invisalign is virtually invisible and eliminates the need for bulky and uncomfortable metal brackets and wires. Clear, thin aligner trays effectively adjust the teeth into the desired position, making the treatment incredibly popular with teenagers and adults. Trays must be removed for eating, drinking, and cleaning the teeth. This avoids the need for patients to restrict their diet or avoid certain foods and drinks. In order for the treatment to be effective, patients must be diligent in wearing the aligners for a majority of the day.
Veneers
Another great treatment for concealing various cosmetic flaws is porcelain veneers. Veneers can also be used to treat a misaligned midline. The veneers are extremely durable and are very natural in their appearance. The thin veneer shell is bonded to the teeth. When they are properly cared for and patients practice good oral hygiene, veneers can last for ten years or more.
