One of the most popular orthodontic treatments out there are clear aligners. They use plastic trays to shift your teeth into a healthier bite. However, since they pop over your smile, they may make you talk a bit differently at first. Before you get worried, it’s not a dramatic change, but you may notice a minor one. Here is what you can expect, whether it’s Invisalign or Angel Aligner.

What Do Aligners Do to My Speech?

Adults and teens alike get aligners because they are discreet options. You’ll wear them for nearly the entire day to keep your treatment on track. But when you talk, your tongue may bump into the trays on occasion. You will likely have a small lisp because of it.

Generally, it makes people pronounce their “s” and “z” sounds as “th.” This can be annoying or embarrassing, but the good news is that it’s only temporary. The trays are made from thin plastic, so the space they take up is very minor. Your mouth will just need a couple of weeks to get fully used to them. In no time, you can confidently say what you want without a worry.

How Can I Get Used to My Aligners?

Despite maybe having a lisp, the good news is that there are things you can do to stop it! Following these simple tips can help you speak clearly and get adjusted to having your aligners in. Here are easy ones to try out:

  • Get the full wear time. You’ll need to wear your aligners for 20 to 22 hours every day, and it’s important that you stick to it! Not only will this help you stay on track and avoid any delays, but it’ll also help you get used to them faster. Taking them out too often may only prolong the transition period.
  • Record yourself while reading. Doing it in the moment will help you understand how it feels to talk with your trays in, but listening back can let you catch anything you might’ve missed. Finding words that are tripping you up will let you take time to correctly pronounce them.
  • Talk with a trusted person. In some cases, having a simple conversation with someone you know can help give you a new perspective to work off of. They can let you know if anything sounds off to them and let you correct yourself.
  • Give yourself some time. The change in speech might be frustrating, but it’s only temporary. You are getting a straight smile you love, so look forward to the results. Once you get adjusted, you are ready to enjoy a smooth treatment.
