One common bite issue people can experience is an open bite, where the upper and lower teeth don’t meet when the mouth is closed. This can create gaps at the front or sides of your smile, making everyday things like eating and speaking more difficult.

There are two main types of open bites:

• Anterior open bite – When your front teeth don’t touch, even when your back teeth are together.
• Posterior open bite – When your back teeth don’t meet, but your front teeth do.

Open bites can be caused by habits like prolonged dummy use, genetics or the way your jaw naturally develops. Luckily, orthodontic treatment can correct this, helping to improve both the appearance and function of your smile.

What causes an open bite?

There are a few common reasons why an open bite can develop:

• Genetics – Sometimes, it just runs in the family. If close relatives have an open bite, you may be more likely to have one too.
• Prolonged dummy or thumb-sucking – Sucking habits in early childhood can push teeth out of position, leading to an open bite over time.
• Jaw development issues – If your upper and lower jaw grow at different rates, they might not align properly, leaving a gap between your teeth.

How orthodontics can fix an open bite

Braces and clear aligners can gently guide your teeth into the right position, helping your upper and lower teeth come together as they should. The best treatment for you will depend on the severity of your open bite, your lifestyle and your personal preference.

Fixed braces

Fixed braces are a highly effective way to correct an open bite. Using brackets and wires, they gradually move your teeth into position, closing any gaps. If needed, elastic bands can be used alongside braces to encourage your upper and lower teeth to meet properly.

Braces provide precise control over tooth movement, making them a great choice for more severe open bites.

Clear aligners

If you’re looking for a more discreet way to fix an open bite, clear aligners like Invisalign and Angel Aligners could be a great option. These custom-made, removable aligners gradually shift your teeth into place without the need for brackets or wires.

Clear aligners can be just as effective as fixed braces, particularly for mild to moderate open bites. To get the best results, they need to be worn for at least 20 hours a day. Like braces, aligners may also require elastics to help guide your teeth into the right position.

Surgery

For severe open bites caused by significant jaw misalignment, surgery may be recommended. This is typically only considered for adults when braces or aligners alone aren’t enough to correct the bite.

How long does open bite treatment take?

The length of your treatment depends on the severity of your open bite, the type of braces or aligners you choose and how well you follow your orthodontist’s advice. You’ll start to notice improvements within a few months, but orthodontic treatment is a marathon, not a sprint.

Sticking to your treatment plan – whether that means wearing your aligners for the recommended hours or keeping up with your elastics – will help you achieve the best results as efficiently as possible.

What happens after treatment?

Once your open bite has been corrected, retainers are essential to keep your teeth in their new position. Without them, your teeth may gradually shift back over time.

Retainers can be removable or fixed discreetly behind your teeth. Our private packages include both for extra peace of mind, ensuring long-lasting results.

Regular check-ups will help keep your smile on track, and maintaining good oral hygiene will protect your teeth and your new bite.
