Invisalign Disadvantages
The product also has potential disadvantages: the very fact that the aligners are removable means they are not continually correcting the teeth. Unlike traditional fixed braces, they are largely dependent on a patient's habits and their consistency in wearing the aligners. The success of the Invisalign aligners is based on a patient's commitment to wear the aligners for a minimum of 20-22 hours per day, only removing them when they are eating, drinking, or brushing their teeth.
The system is also somewhat expensive, as conceded by the Align company, and can be more expensive than traditional wire and bracket systems. However, this is an orthodontic procedure that is usually partially covered by dental insurance, if that insurance covers orthodontic procedures.
The aligners must be removed for eating. They and the teeth should be cleaned before re-inserting afterwards. This can be troublesome for people who are constantly snacking and may mean the patient has to clean their teeth up to six times daily. On the other hand, the more frequent brushing and closer attention to dental hygiene helps ensure that the patient will develop improved dental habits that they will continue after their aligner treatment is over.
By their very nature, Invisalign aligner trays are not as proficient as fixed braces at moving teeth in the vertical dimension. Certain teeth are also slightly problematic for Invisalign aligners to rotate. Some lower pre-molars with their rounded shape can be difficult for the aligners to grasp and apply a rotational force to.
Unlike traditional braces, if a patient grinds or clenches his or her teeth during the day or while sleeping, the aligners can become damaged. In practice, however, this problem is very rare and a new aligner can be ordered. Also, similar to traditional metal braces, aligners may cause a slight lisp at the beginning of treatment. This usually disappears as the patient becomes used to the treatment.
The aligners are constructed of implantable grade polyurethane, and the Align company has acknowledged that, though extremely rare, there may be cases of allergic and toxic sensitivity reactions to Invisalign. Minor symptoms such as sore throat, cough, and nausea have been reported. In more serious cases, the FDA has received reports of systemic swelling or throat pain that has extended to the upper chest and wind passages requiring emergency medical treatment and discontinuation of the Invisalign treatment.While the Invisalign company provides no information except the MSDS (material safety data sheet) directly to patients or orthodontists, working through the patient's orthodontist Invisalign will make the aligners with several different materials to attempt to reduce toxic or allergic sensitivity.
Should the treatment go off track, or patients fail to keep the aligners in for the required length of time, then the next aligner in the series will not fit, and a new set of impressions and aligners will be necessary, adding to the cost. This reinforces the fact that the patient must be committed to the success of his or her Invisalign treatment.
Complications and risks Of Braces
Plaque forms easily when food is retained in and around braces. It is important to maintain proper oral hygiene by brushing and flossing thoroughly when wearing braces to prevent tooth decay, decalcification, or unpleasant color changes to the teeth.
There is a small chance of allergic reaction to the latex rubber in elastics or to the metal used in braces. In rare cases it results Ulcerative Colitis. Latex-free elastics and alternative metals can be used instead. It is important for those who believe that they are allergic to their braces to notify the orthodontist immediately.
Mouth sores may be triggered by irritation from components of the braces. Many products can increase comfort, including oral rinses, dental wax or dental silicone, and products to help heal sores.
Braces can also be damaged if proper care is not taken. It is important to wear a mouthguard to prevent breakage and/or mouth injury when playing sports. Chewing gum and certain sticky or hard foods, taffy, such as raw carrots, large hard pretzels, and toffee should be avoided because they can damage braces. Frequent damage to braces can prolong treatment.
In the course of treatment orthodontic brackets may pop off due to the forces involved, or due to cement weakening over time. The orthodontist should be contacted immediately for advice if this occurs. In most cases the bracket is replaced.
When teeth move, the end of the arch wire may become displaced, causing it to poke the back of the patient's cheek. Dental wax can be applied to cushion the protruding wire. The orthodontist must be called immediately to have it clipped, or a painful mouth ulcer may form. If the wire is causing severe pain, it may be necessary to carefully bend the edge of the wire in with a spoon or other piece of equipment (e.g. tweezers) until the wire can be clipped by an orthodontist.
Patients with periodontal disease usually must obtain periodontal treatment before getting braces. A deep cleaning is performed, and further treatment may be required before beginning orthodontic treatment. Bone loss due to periodontal disease may lead to tooth loss during treatment.
In some cases, teeth may be loose for a prolonged period of time. One may be able to wriggle one's teeth for a year or two after treatment or longer.
The dental displacement obtained with the orthodontic appliance determines in most cases some degree of root resorption. Only in a few cases is this side effect large enough to be considered real clinical damage to the tooth. In rare cases, the teeth may fall out or have to be extracted due to root resorption.
Pain and discomfort are common after adjustment and may cause difficulty eating for a time, often several days. During this period, eating soft foods can help avoid additional pressure on teeth.
The metallic look may not be desirable to some people, although transparent varieties are available.
YOU DECIDE!
