Can Invisalign widen your jaw? - National Dental Care

Invisalign is a very popular way of straightening teeth which uses near-invisible clear plastic aligners custom-made for your teeth.  Because the Invisalign treatment gradually changes the positioning of your teeth to correct crowding and issues like crossbite, your smile widens as your teeth become more visible either side of your mouth.

While not actually affecting the shape or structure of your jawbones, straighter teeth can create the effect of a broader and more aesthetically attractive jawline, even when you’re not smiling. This effect is a bonus, as there are a number of reasons you might need Invisalign treatment.


Problems with crooked teeth


Getting your teeth straightened isn’t just about creating a better smile or a wider-looking jaw. If you have crooked teeth, you probably also have some jaw alignment issues which can cause further problems.

Your jaws are meant to close comfortably, but if your jaws are being pushed out of alignment you may develop pain in your jaw and uneven wear on your teeth. Crooked teeth are much harder to keep clean and dental problems are harder to spot with overlapping teeth. You may also develop periodontal issues from trapped food creating gum infections.

Whether you have a crossbite (where your jaw closes at an angle), an underbite (your bottom jaw projects past your top jaw) or an overbite (the top jaw is too far over the bottom jaw), you will have additional dental issues. Getting your teeth straightened is not just for aesthetic reasons, it’s also important to make your dental hygiene much easier and more effective.


Age can narrow your smile


Aside from darkening your teeth, (which can be treated with professional teeth-whitening procedures), ageing can also gradually narrow your smile and the appearance of your jaw width. As you age your teeth can slowly move inwards with jawbone and gumline issues.

If you had braces when you were younger and stopped wearing your retainer, your teeth are also likely to gradually move back to their original positions. This also creates the effect of a narrower smile and jaw.

If you’ve lost a tooth a while ago which wasn’t replaced with an implant or bridge, the teeth either side of the space will also move inwards, causing adjoining teeth to also move inwards. This then narrows your smile. If you want to have the tooth replaced, you may need straightening first to move teeth back so an implant can be correctly positioned.


Is Invisalign suitable for you?


Your National Dental Care practitioner will be able to assess if you are suitable for Invisalign treatment. If you have some particularly crooked teeth you may need to have braces to straighten those teeth first, before Invisalign can be used. Any periodontal issues will also need to be dealt with before you can begin Invisalign.

Your dentist will be able to explain your treatments and what they will cost. They will also be able to show you computerised images of how your teeth will look during and after your treatment. You can book your National Dental Care appointment online now.
