Invisalign is an innovative orthodontic treatment designed to help people achieve a beautiful smile without traditional metal braces.

Using custom-made aligners, Invisalign gradually shifts misaligned teeth into place throughout 6 to 12 months.
Invisalign uses a series of plastic aligners that apply gentle pressure on your pearly whites to get straighter teeth. The invisible braces are swapped out every one to two weeks and worn for 20-22 hours daily.

Invisalign was founded by a company called Align Technology, founded in 1997. The company’s mission was to create a more discreet and comfortable alternative to traditional metal braces. Thus birthed the first Invisalign aligners in 1999.

The initial product was only approved for use in the United States. But they gained popularity, and the company began expanding into international markets.

How Invisalign Benefits Your Speech

  • Straightening teeth.
    Misaligned teeth and gaps in your smile can result in speech impediments. They may lead to difficulty pronouncing certain words and syllables, resulting in slurring and mumbling. Straighter teeth also help you form sounds better, allowing you to create the right shape for your mouth when speaking.

  • Improved oral health.
    Poor oral health doesn’t just affect your looks. Some orthodontic issues, such as an overbite or underbite, could impact the way you speak. The results of improved oral health due to Invisalign can lead to better speech habits.

  • Increased self-confidence.
    Invisalign benefits your speech through increased self-confidence. They help you feel more comfortable and confident in your appearance. In addition, having straighter teeth can improve your smile, increasing your self-confidence. This can make it easier for you to speak clearly and confidently.

  • Comfortable and discreet.
    Unlike conventional braces, Invisalign is custom-moulded to your smile. As a result, the aligners have a snug fit over your tooth surfaces, making speaking easier.

Does Invisalign Affect Speech?

If you’re worried that Invisalign will make your speech sound different, don’t worry! Many people share the same valid concern. While some people may initially experience slight difficulty, the issues will resolve themselves in a few weeks.

How does Invisalign affect the way you speak?

You may notice a slight lisp when you start wearing your Invisalign aligners. But, this is temporary and will go away after the adjustment period.

How long does it take for the lisp to go away?

The lisp should go away within a week or two. However, if it persists, you can consult with your dentist about lisp exercises.

When It Comes To Speaking, What Advantage Does Invisalign Have Over Conventional Braces?

The main advantage of Invisalign compared to conventional braces is that it’s more discreet and doesn’t interfere with the sound of your voice.

Conventional metal braces can cause difficulties with speech. For example, they can cause sound distortions and affect how you pronounce certain words.

Can I Still Be Understood While Speaking With Invisalign?

In most cases, yes. The effects of Invisalign on speech are minor. There’s a period of adjustment with these orthodontic appliances, but you’ll get used to speaking with your new aligners in place.

How Invisalign Affects Speech

Conventional metal braces are the most widely used option when it comes to straightening teeth. However, these dental appliances can interfere with normal speech. They can cause speech alterations like lisping or slurring. This happens because the brackets and wires block your tongue from correctly forming sounds when speaking.

Invisalign, on the other hand, doesn’t affect the tongue’s movement while speaking. The aligners are designed with a flexible plastic material that reduces speaking discomfort.

Additionally, Invisalign allows you to take out your aligner when needed. For example, you can pop them out during meal times or a major event!

Invisalign works by repositioning teeth over time. This gradual movement of your teeth can cause some temporary changes in how you speak.

  • Lisps and Whistles.
    When wearing Invisalign, it’s common for some people to notice a lisp or whistling sound. This common speech issue is due to the slight gap left between your upper and lower teeth when speaking. This will resolve as your teeth become accustomed to their new positions.

  • Slight Difficulty Pronouncing Words.
    You may also experience some slight difficulty pronouncing certain words at first. This is because of your tongue’s unfamiliar shape and placement against your realigned teeth.

  • Dry Mouth.
    The extra thickness surrounding your mouth may cause a dry mouth which could interfere with your tongue movements. This can easily be resolved by drinking water.

While these speech changes may be noticeable when using Invisalign, they usually decrease within 2-3 weeks after beginning treatment. You’ll experience clearer speech in a couple of weeks.

Tips for Overcoming Speech Issues with Invisalign

Here are some techniques you can use to help you speak clearly with Invisalign:

  • Stay hydrated.
    Drinking plenty of water can help keep your mouth hydrated and reduce the symptoms of a dry mouth.

  • Practice speaking.
    Speak at a more relaxed pace. Practising speaking can help you get used to speaking with Invisalign and improve your speech clarity. You can also practice speaking in front of a mirror to help you see how your mouth moves.

  • Relax your mouth and jaw.
    Tension in these muscles can make it harder to produce clear speech. You can also practice tongue exercises to loosen up the muscles around your mouth.

  • Pause and take breaks.
    Take a break and give your mouth time to rest and rehydrate.

  • Adjust the fit of your aligners.
    If your Invisalign aligners are too tight, they can cause discomfort and speech difficulties. Should you experience this issue, talk to your dentist about adjusting the fit of your aligners.

How Long Does It Take for Speech to Return to Normal After Starting Invisalign?

When you start using Invisalign, the aligners can temporarily have an Invisalign speech impact. This is because they affect how air passes through and around your lips when speaking. However, as you adjust to wearing the aligner, you’ll find that your speech returns to normal over time.

The amount of time it takes for speech to return to normal after starting Invisalign varies on different factors. These include age, lifestyle, and the number of aligners in a treatment plan.

Can You Avoid Speech Issues with Invisalign?

Here are some things you can do to get good speech clarity with Invisalign

  • Get a good fit.
    One way to avoid speech issues with Invisalign is to ensure the aligners fit properly. If they don’t fit correctly, it can cause lisping and slurring of words.

  • Wear your aligners on time.
    Another practice is to put your aligners in at the right time. Wear your aligners 20-22 hours a day. But, if they’re put in too early or taken out too late, it can have a big Invisalign speech impact.

  • Practise good oral hygiene.
    Taking out your aligners when you eat or drink anything besides water is also important. This keeps them clean and ensures they won’t interfere with your speech patterns when talking.

Personal experiences with avoiding speech defects vary per case. Some people found that their speech was unaffected by Invisalign. Other people reported some slight lisping. But, these issues were overcome fairly quickly by speaking slowly or paying more attention to pronunciation.

When to Seek Help for Speech Issues with Invisalign

Here are some signs that you may need help with Invisalign and speech correction:

  1. Impaired speech clarity with Invisalign.
    Slurred speech and difficulty pronouncing words may show issues with your Invisalign.

  2. Tongue irritation.
    This could be a sign that your aligners are rubbing against your tongue and causing discomfort.

  3. Excessive saliva production.
    Some people may experience an increase in saliva production when they first start wearing Invisalign. However, this should subside over time as you get used to the aligners.

  4. Pain when speaking.
    Initial discomfort is expected when you first start Invisalign treatment. However, pain is of adverse effects or serious dental conditions. Therefore, its occurrence shouldn’t be taken lightly.

If you’re experiencing any of these speech alterations, contact your dentist. They can assist you with both your Invisalign and speech correction.

When to Seek Help From a Speech Therapist

Speech issues associated with Invisalign are usually self-limiting. However, if you notice issues with speech clarity with Invisalign, it may be time to see a speech therapist. Speech therapists can provide treatment for any type of communication disorder, including those stemming from Invisalign.

How to find a speech therapist who specialises in helping people with speech issues related to Invisalign

  • Do your research.
    Ask family and friends if they know any therapists specialising in this expertise field. Also, look online for recommendations or reviews of local therapists.

  • Contact local hospitals.
    Call local hospitals and universities to inquire about their list of experienced professionals.

  • Ask for referrals from your dentist.
    Your dentist may have patients with similar problems. Ask for referrals or other helpful information about therapists who specialise in this field.

Other Options for Straightening Teeth Besides Invisalign

  • Traditional braces.
    Traditional braces are a tried-and-true method to achieve straight teeth. Braces need frequent visits to your dentist for adjustments. They take 18-24 months to achieve the desired results.

  • Clear aligners.
    This offers a less noticeable way to straighten teeth and is becoming increasingly popular. Clear aligners are made of a strong plastic that fits over your teeth and can be taken out while eating and brushing your teeth. Visits to the dentist are still necessary during treatment, but they take less time than braces – usually 8-18 months.

  • Dental bonding.
    This procedure involves using composite resin that matches your teeth to reshape and fill in gaps between teeth. It’s a much quicker process and can be completed in one visit. However, dental bonding requires more maintenance than options since they’re susceptible to staining.

  • Dental veneers.
    Veneers are thin porcelain shells that fit over your existing teeth to change their shape and size or hide minor imperfections.

The Pros and Cons of Other Teeth Straightening Options

  • Traditional braces
    • Pros: Traditional braces are an effective and reliable way to move your teeth into the desired position. They’re also more affordable than other options and can be adjusted by your dentist.

    • Cons: Traditional braces can be uncomfortable and require regular adjustments. They also require special care when cleaning your teeth. In addition, it can take longer to see results, and the brackets and wires can sometimes cause irritation or cuts in the mouth.

  • Clear aligners
    • Pros: Clear aligners are made of plastic trays that fit snuggly over your teeth. They’re virtually invisible, so you won’t have to worry about feeling self-conscious while you wear them. Plus, they make brushing and flossing your teeth easier because they’re removable.

    • Cons: Clear aligners require consistent wear for optimal results. But you must remember to take them out when eating or drinking anything besides water. Also, more than clear aligners is needed for complex alignment cases. Traditional braces might be a better option for achieving desired results in such cases.

  • Dental bonding
    • Pros: Dental bonding is a great way to address minor misalignments without having to go through a lengthy orthodontic process. The process is painless and cost-effective. You only need one appointment with your dentist.

    • Cons: Dental bonding has a shorter lifespan than metal brackets or trays. They’re also susceptible to cracking.

  • Dental veneers
    • Pros: Dental veneers allow you to get straighter teeth without any visible hardware on your teeth. Instead, thin shells are placed over your existing teeth for a seamless look. In addition, they don’t require any type of realignment process.

    • Cons: Your teeth need to undergo alterations. Some enamel is scraped off before attaching the shells so they look natural when completed. Also, dental veneers have a longer turnaround time than other methods. They also tend to cost more than other types of tooth straightening procedures.

There are many different ways you can go about straightening your teeth. Each method comes with its own unique pros and cons that should be taken into consideration before committing to the procedure.

Choosing the Right Teeth Straightening Option for You

Choosing the right teeth straightening option can be a difficult decision. There are several options available to straighten crooked or misaligned teeth. Each option has its own unique benefits and drawbacks. So, it’s important to consider several factors when choosing the right option for you.

  • Cost:
    The cost of teeth straightening can vary greatly depending on your chosen option. Dental veneers and clear aligners can be more expensive. Dental bonding and traditional braces are usually cheaper.

  • Length of treatment:
    This also varies depending on the option you choose. Traditional braces can take several years to achieve the desired results. However, clear aligners and Invisalign can take anywhere from 6 to 18 months. Dental bonding and veneers are the quickest options but may not address underlying orthodontic issues.

  • Comfort:
    Comfort is an important factor when choosing a teeth straightening option. Traditional braces can be uncomfortable and may cause mouth sores. Clear aligners and Invisalign are much more comfortable and less likely to irritate. Dental bonding and veneers are also more comfortable.

  • Visibility:
    If you’re concerned about visibility, consider clear aligners or Invisalign. These options are virtually invisible and will not be noticeable to others. Traditional braces are visible, while dental bonding and veneers blend seamlessly into your teeth.

Final Thoughts

Invisalign is a type of clear aligner used to straighten teeth. They can initially affect speech in some people due to their thickness and placement in the mouth. However, most people adapt to the aligners within a few days to a week, and speech usually returns to normal.

In rare cases, some people may experience a slight lisp during treatment, but this usually resolves as they continue to wear the aligners.
