Today, for both children and adults, there is an array of dental and orthodontic treatments available. For instance, among the most used ones include braces, retainers, and tongue cribs.

To answer all of your questions, we gathered the top things you should know on using a TPA appliance. Read on to learn more.
What is TPA appliance?
TPA appliance or Transpalatal arch represents an orthodontic tool. The tool mainly focuses on the upper jaw and acts as a palatal expander of the roof of the mouth. The appliance’s main mission is to reposition molars in a manner than braces cannot do. Because of its intensity, a TPA appliance is acts more detail-oriented and fixes whatever braces can’t.
Typically, a trans palatal arch appliance is placed around the upper molars of the mouth. Next, the dentist inserts a stainless steel wire to connect the appliance from one side of the mouth to the other.
In some cases, to make more use of the TPA appliance, dentists will recommend tooth extraction first. This applies to both children and adults and is necessary, so the healthy teeth can settle in the mouth better. A TPA appliance has the job of keeping the first molars in place, and the sooner you start using it the better results you can expect.
How do I know I need a TPA appliance?
There are several early indications that you might be in need of a TPA tool. One indication of it is a total or partial loss of baby molars. Anther indication of it is a total or partial loss functionality of permanent molars. TPA appliance is used commonly during growth guidance phase 1 orthodontic care. If you notice anything out of the ordinary, don’t hesitate to consult your dentist or orthodontist.
How can I get TPA appliance?
Given that your doctor already diagnosed you, he or she will proceed on placing the tooth separators first. The tool’s separators will be positioned on the molars and secured. Then, you are good to go. The entire process does not take up more than 20 minutes, if all goes well, that is. But, you are still not done.
Now, you are also to schedule a follow-up appointment with your orthodontist. This is best done 3-14 days post installing the spacers. If the separators have adjusted well, your orthodontist will choose proper bands for your teeth.
For this, your orthodontist will need to take a mold of your teeth or an impression. He or she will insert a rubbery-like paste in your mouth, this getting the impression. This will serve the orthodontist to make the most suitable bands. The process of molding and getting the bands done takes up to three weeks.
When it comes to applying the TPA tool, it takes glue to attach the bands around your teeth. The TPA will help align the teeth better, either pre or post wearing braces.
What are the benefits of wearing a TPA appliance?

How to maintain your TPA appliance?
All patients who are wearing a TPA appliance should keep it clean at all times. You can also use your toothbrush to clean the tool even better. Steer clear of consuming chewy and hard food, as they can damage the appliance.
If you notice your TPA appliance is broken, don’t hesitate to visit your orthodontist to get it fixed. Check your bands daily, and if you notice a change or distortion, report it to your dentist. In addition, you might feel some discomfort at first, so you can take a mild painkiller to manage it.
How effective are TPA appliances?
Dentist and orthodontists worldwide agree that a TPA appliance improves your overall oral health. Once your teeth and molars are in place, it means your TPA appliance did its job right, and now it is time to install braces. Wearing a TPA appliance works wonders for the braces, and it eases the road to the perfect teeth. Also, by wearing a TPA appliance accordingly, you can shorten the period for wearing braces.
The appliance has a greater effect in children, whereas adults need time before seeing the effect. Children develop more easily, so their teeth and gums do as well. Therefore, the recovery process of wearing a TPA appliance is faster.
If you notice any dental issue whatsoever, don’t hesitate to address it as soon as possible. Be wise and give your oral health the attention it deserves. Teeth and jaw problems are best solved on time. Therefore, make an appointment with your dentist, and determine if you need a TPA appliance or a related treatment.
Understanding how the teeth fit in the mouth can be difficult, but it is clear that there are times when they do not come through the correct way. It could be because the jaw is too small and there are only a few options such as extractions of baby teeth. If the child should undergo a few sessions of baby teeth removal to make sure that there is enough space, TPA appliance can be used to maintain the back teeth from moving forward – this refers to a trans palatal arch appliance.
A TPA appliance is just what it sounds like – an appliance that is placed across the palate. The maxillary first molar teeth are selected and have orthodontic bands attached to them. The other end of the bands is then attached to the TPA appliance. It is a device used to do to the upper jaw what a lingual arch can do for the lower one. The main reason for using one is to keep the first molars in place. When there is a space in the jaw it is easy for them to move forward and an arch maintainer is required.
If the teeth have to be taken out, the molars will be forced to stay where they are with the TPA appliance rather than move into the newly open up space. In children, the adult teeth will come through and take up the space. In adults, there will be the need to find another way to fill the gap. Leaving the space alone is not really an option as the molars could move and a lot of teeth could end up out of position.
This will not take long as it is a simple matter of placing the appliance with the bands in the mouth and using dental glue to hold it in place. Once in place, it will stay there until the extractions can take place or there is no risk of back teeth moving forward. As soon as the TPA appliance is not needed, it will be removed and the fixed brace can now be used.
