will a mouthguard straighten my teeth

Many people are looking for ways to straighten their teeth without having to undergo traditional orthodontic treatment. One popular option that has gained traction in recent years is the use of a mouthguard. But does wearing a mouthguard actually straighten teeth? In this article, we will explore this question from various angles to give you a comprehensive understanding of the topic.

What is a Mouthguard?

A mouthguard is a dental device that is worn over the teeth to protect them from injury during sports or other physical activities. It is typically made of a soft, flexible material that conforms to the shape of the teeth and gums. Mouthguards are also sometimes used to treat teeth grinding and clenching, as well as to help alleviate symptoms of temporomandibular joint (TMJ) disorder.

How Does a Mouthguard Work?

When you wear a mouthguard, it creates a barrier between your teeth and the forces that could potentially move them out of alignment. This can include impacts from sports or other physical activities, as well as the pressure that is exerted when you grind or clench your teeth. By preventing these forces from affecting your teeth, a mouthguard can help to maintain their current position and prevent them from shifting further out of alignment.

Types of Mouthguards

There are several different types of mouthguards that you can choose from, depending on your needs and preferences. These include:

  • Stock mouthguards: These are pre-made mouthguards that come in a standard size and shape. They are the least expensive option, but they may not fit well and can be uncomfortable to wear.
  • Boil-and-bite mouthguards: These mouthguards are made of a thermoplastic material that softens when boiled. After boiling, you bite down on the mouthguard to create a custom fit. They are more expensive than stock mouthguards, but they offer a better fit and more comfort.
  • Custom-fitted mouthguards: These are made by a dentist or orthodontist who takes impressions of your teeth to create a custom-fit mouthguard. They are the most expensive option, but they offer the best fit and protection.

Can a Mouthguard Straighten Teeth?

While a mouthguard can help to prevent teeth from shifting further out of alignment, it is not designed to actually straighten teeth. In order to move teeth into a new position, a force must be applied to them over a period of time. This is typically done through orthodontic treatment, such as braces or clear aligners.

Other Ways to Straighten Teeth

If you are looking to straighten your teeth, there are several other options that you can consider. These include:

  • Braces: Traditional braces use brackets and wires to gradually move teeth into a new position. They are the most effective way to straighten teeth, but they can be uncomfortable and may require dietary restrictions.
  • Clear aligners: Clear aligners, such as Invisalign, use a series of clear plastic trays to gradually move teeth into a new position. They are less noticeable than braces and can be removed for eating and brushing, but they may not be as effective for complex cases.
  • Dental veneers: Veneers are thin shells of porcelain or composite resin that are placed over the front of teeth to improve their appearance. While they do not actually straighten teeth, they can give the illusion of a straighter smile.


While a mouthguard can be a useful tool for protecting your teeth from injury and preventing them from shifting further out of alignment, it is not a substitute for orthodontic treatment if you are looking to straighten your teeth. If you are interested in straightening your teeth, it is best to consult with a dentist or orthodontist to determine the best treatment plan for your individual needs.
