The Truth About Invisalign: 3 Complications You Should Know

If you are planning to undergo orthodontic treatment, such as Invisalign, you may often hear about its benefits. You will enjoy a more comfortable experience compared to braces while also being able to keep to your normal diet, since the trays can be removed. However, there isn’t a dental service without complications. Aligners are no different, as some things can catch you off guard if you don’t know about them! Here are three that you should be aware of.

1.)  Discomfort or Soreness

Invisalign works because it applies pressure that slowly shifts your teeth into their desired positions. You’ll wear trays for 20 to 22 hours every day and swap to a new set every week or so. This will keep your smile-straightening journey on track.

However, it’s expected and normal that you will have some soreness when you wear new aligners. This minor discomfort is a sign that the treatment is working, but it may be frustrating to deal with it if you don’t know how to. Thankfully, you can get relief by drinking cold water, taking over-the-counter medication, or eating a soft food diet for a couple of days.

2.)  Changes to Your Speech

Your Invisalign trays are made from a thin plastic that will fully cover your smile. As small as they are, it’s still a new oral appliance in your mouth. They take just a tiny bit of room, but your tongue may be more prone to bumping into them. Many people develop a minor lisp initially, but it’s temporary and short-lived. By practicing reading and talking, you can get rid of this speech change.

3.)  Restorations Can Dislodge

Fillings, crowns, or bridges can cause problems for your Invisalign. Your trays are customized to your teeth, so the fit isn’t an issue, but rather the pressure. Your restoration can become loose because of the applied force, but your dentist will adjust your treatment to try to avoid this happening. If it does, then you’ll need to stop wearing your aligners and visit your dentist to make sure your teeth stay safe.

Should I Still Get Invisalign Despite These Complications?

In the end, the above complications shouldn’t stop you from getting the healthier bite you deserve. Most can easily be dealt with by following simple tips and going through a short adjustment period. The results you get with Invisalign can last a lifetime compared to the temporary and expected discomfort you’ll feel. Instead, look forward to enjoying a treatment that helps you feel confident once you finish your journey with them.
