To make your smile wider, do this exercise every day: Keeping your lips in a closed (no teeth showing) smile, try to stretch the corners of your mouth out as far as you can. Hold this for 10 seconds. While holding that position, purse your lips slightly, so your teeth show just a little.
You can widen your smile through dentistry.
Options like braces, oral surgery, or palate expanders involve reshaping your jaw bone structure to widen your smile. If you have a large mouth with misaligned teeth, Invisalign may do the trick too.
Orthodontic solutions, such as fixed braces or Invisalign, are another way to improve the look of a narrow smile. Both metal and clear braces are designed to re-align the teeth to widen the smile. In most minor orthodontic cases, a clear aligner like Invisalign can help straighten the teeth.
Straightening & Whitening With Veneers
Veneers were originally invented as a quick fix for the teeth of Hollywood stars, and they're still a great way to re-shape your smile quickly and easily. Veneers are thin porcelain sleeves that are slipped over your natural teeth and permanently cemented in place.
Smile exercises are a real thing that can make your smile bigger. That's right — if you build up the muscles around your mouth a little, they'll open your smile up to show more of those pearly whites. All you need to do is a few quick exercises every day and you'll be on your way to a bigger smile.
Over time, teeth can start to tip inward. As this happens, the space at the corners of the mouth between the teeth and cheeks (called buccal corridors) expands. The back teeth end up in the shadows of those “corridors”, adding to the narrowed look.
If you want to widen your mouth, your orthodontist will likely recommend a palatal expander. This orthodontic appliance is fixed to the upper arch of teeth. The patient uses a key to slowly crank the device and push against the molars to widen the jaw.
Furthermore, patients begin to notice that their teeth are shifting inward and their smiles become more narrow and less full and wide. The problem is quite real and common, as we get older. We call it the “aging dentition.”
Exercise – Special mouth exercises exist that can help you open your mouth wider and stretch your smile a little further. Try this one: keep your lips together and try to smile as wide as possible. Hold for at least ten seconds.
The general rule of thumb is around 6 months, but can be much longer.
Scientists studied the perfect smile and found that people without broad smiles tend to hide their teeth the most when smiling. They showed that wider smiles are more attractive due to the correct balance of asymmetrical teeth.
The upper and lower lip should both be symmetrical, and their centres should meet at the midline of the face. All teeth should be straight. The top teeth should be dominant; while smiling, little to nothing of the bottom teeth should be shown.
The width of the smile
A study published in the Journal of the American Dental Association says most people respond better to a broad smile. The so-called perfect smile should be at least half the width of the face.
But Invisalign® treatment doesn't actually widen your teeth. Instead, Invisalign® shifts your teeth into place to give you the appearance of a wider smile. It's a critical distinction. Even the slightest shift of your teeth by a few millimeters can make a noticeable impact on your smile.
If you want your smile to appear pleasant, you might want to avoid a dazzling beam, research suggests. A study by scientists in the US has found that wide smiles with a high angle and showing a lot of teeth are not the best at creating a positive impression.
Ideally, your smile should reveal most of your teeth and form a gentle arc, sweeping back into the “buccal corridor,” the dark space between your teeth and the corners of your mouth. A little dark space is important to create contrast and make your teeth seem whiter.
Particularly on the lower front teeth, crowded and crooked teeth are a common indication of an aging smile. Another natural part of the aging process on our teeth is a forward motion toward the front of the mouth. This leads to the small front teeth (incisors) all piled upon each other in severe crowding.
Melvyn Goodale, director of the Brain and Mind Institute at Western University in Canada. The researchers believe that smiling makes a person look older because of the wrinkle lines that form around the eyes. A surprised face, however, lifts and pulls the skin backward, smoothing any potential age-related wrinkles.
You cannot wholly reverse aging—it's a normal part of life. However, you may be able to slow it down and help prevent age-related diseases by adopting a healthy lifestyle. That includes habits like eating a healthy diet, wearing sunscreen every day, and exercising (Shanbhag, 2019).
