Why Can’t I Close My Mouth With Invisalign?

You cannot close your mouth with invisalign because during the initial few days of invisalign treatment, your mouth becomes sore as a reaction to the new appliance in the mouth.

Not being able to close mouth with invisalign is a temporary problem and will eventually go away within a week of invisalign use.

If you are not able to close your mouth due to discomfort from sharp edges in invisalign, consult your orthodontist immediately to get sharp edges trimmed.

Regular mouth exercises such as chewing styrofoam chewie may help blood flow to teeth and gums and prove beneficial in healing the inability to close mouth.

What Is Invisalign?

Invisalign is a brand name for clear aligners or braces. It is considered to be more aesthetic and more comfortable in comparison to normal metal braces.

Invisalign are not completely invisible but may be less visible than other braces available.

What Are The Different Types Of Dental Issues That An Invisalign Can Address?

As per the claim of the brand, invisalign may be useful in addressing the following dental issues:

  • Overbite and Underbite issues
  • Crossbite issues
  • Issues of Open Bite
  • Gap between the teeth
  • Overcrowding of the teeth

As per research studies, not much has been studied about the effectiveness of the invisalign and hence nothing much can be said on the brand claim due to lack of sufficient research data.

Do Invisalign Braces Help With Teeth Grinding?

Yes, braces do help with teeth grinding if it occurs due to misaligned or crooked teeth. 

Braces may help realign the teeth and correct the bite to give relief or completely eliminate the problem of teeth grinding.

How Do Invisalign Braces Help With Teeth Grinding?

Invisalign Braces may help realign the teeth and correct the bite to give relief or completely eliminate the problem of teeth grinding.

Invisalign Braces actually make your teeth straighter or more aligned by applying pressure on them in a particular desired direction. 

The pressure allows teeth to become loose and reposition themselves according to the direction of force.

Your orthodontist may call you once in a month for follow-up and check if the invisalign braces are applying enough pressure for necessary orthodontic movement.

In some cases, headgears may be recommended to you for increased pressure along with invisalign braces.

Considerations After Invisalign Braces

Once the orthodontist feels that the desired result has been achieved and your teeth are now aligned as desired, braces will be taken off.

After taking out the braces, a thorough examination of the teeth and oral cavity is done to make sure all the bites are normal and you don’t feel any discomfort.

X-ray may also reveal any wisdom tooth erupting. If that is the case, your orthodontist may recommend extraction of the wisdom tooth before letting it erupt and disturb the new alignment.

Once everything is checked, your orthodontist will give you a new appliance to wear. This new appliance is called retainer and is very important to wear after braces are taken off. 

Retainer helps to retain and maintain the new alignment until all the jaw bones, gums and mouth structures are adjusted to the new alignment.

The time duration of wearing such retainers may vary from person to person.

  • Use Dental Wax: Sharp edges in invisalign may cause discomfort to your mouth and tongue. Hence, use of dental wax to lessen discomforts from small edges of invisalign is recommended. 

In case of very sharp edges, visit your dentist to get it removed.

  • Use peroxide-based mouthwash: Peroxide-based mouthwash may help heal the tongue and mouth sores. It also helps to attain a fresh breath and maintain good oral hygiene.
  • Safely remove your invisalign tray: Inappropriate pulling out of invisalign tray from your mouth may cause the plastic to wrap and ill-fitting of your invisalign. It is recommended to remove your invisalign inside-out using clean hands or use an orthokey for ease.
  • Practice chewing exercises: Chewing exercises using a styrofoam chewie may help blood flow to teeth, jaw and gums. Good amounts of blood flow help heal the soreness due to invisalign. It is recommended to practice chewing exercises several times in a day.
