    What Is an Underbite?

    Person with an underbite

    An underbite or Class III malocclusion is when your lower teeth sit more forward than your upper teeth. It happens as a result of misaligned jaws.

    There are different levels of an underbite. A minor case of malocclusion can be imperceptible to other people. In severe cases, the lower jaw can visibly protrude outward and beyond the upper jaw.

    The level of severity can make some daily activities difficult and make you feel self-conscious about your appearance. However, it can also be the cause of other health conditions such as jaw pain, mouth breathing, sleep apnea, and speech impediments.

    Causes of Underbite

    Underbite can occur as a result of:


    An underbite is a hereditary condition that you likely inherited from your parents or a relative. If there is another family member with malocclusion, it means that it is a genetic condition.

    Injury to upper teeth and jaw

    Physical injury to the jaw can cause it to break, leading to misalignment. If jaw surgery doesn’t help the bone heal properly, it can cause an underbite.

    Childhood Habits like Mouth Breathing

    Extreme and prolonged thumb sucking, pacifier use, and bottle feeding can cause the jaw to change shape. These things are normally associated with little children and are not a cause for concern if done in moderation.


    Jaw tumors and cysts can vary in size. Larger ones can displace or even destroy surrounding tissue, causing jaw misalignment. Over time, this can lead to an underbite or another form of malocclusion.

    What Age Should You Check for and Fix an Underbite?

    It is important to address this condition as soon as you notice the onset of an underbite, especially in children. Starting treatment early is key to managing the level of malocclusion and preventing severe cases.

    The American Association of Orthodontists recommends that children see an orthodontic specialist before the age of 7 to discover any functional shifts and crossbites. The bones are still growing and forming at a young age, and early orthodontic treatment can be more effective.

    Depending on the severity of the malocclusion, there is a range of treatment options for adults as well. Mewing has proven to help deal with issues relating to upper and lower jaws by improving your tongue posture.

    First off, what is Mewing?

    Underbite treatment with mewing

    Mewing, or orthotropics, is a set of do-it-yourself exercises created by British orthodontist John Mew. It is a natural, nonsurgical way of treatment of different conditions in the mouth and facial area.

    Mewing is the practice of proper tongue posture by placing the tongue on the roof of the mouth without touching the front teeth and lifting the posterior third of the tongue to allow nasal breathing.

    Correct tongue placement helps to keep the jaws well aligned, opens the airways, and strengthens the jaw muscles. The mewing long-term benefits include resolving various health issues, such as sleep apnea or temporomandibular joint disorder.

    Proper tongue position opens the airways and reduces the chances of breathing problems that lead to mouth breathing and heavy snoring. It will alleviate jaw pain and TMJ-related aches.

    In most cases, mewing is done for cosmetic reasons. Tongue posture exercises can help improve a receding chin or double chin and define the jawline. It is a growing movement popular among wellness professionals as it offers an alternative to corrective jaw surgery. For the full Mewing 101, head to our blog.

    How Reliable Is Mewing?

    Is mewing fake? Long years of practice and relevant experience show that mewing is very much real and effective in dealing with issues related to the face, throat, and neck. You can find a multitude of positive experiences shared on social media.

    There is no scientific evidence of the effects of mewing. Still, the medical community is becoming increasingly interested in this technique and its benefits. You can always read Prof. John Mew’s The “Tropic” Premise on proper jaw alignment that accentuates the benefits of mewing in children and younger adults.

    Mewing and Teeth Alignment

    If you want to straighten out your pearly whites, you may be asking yourself, “can mewing make your teeth straight“?

    Practicing mewing will tackle the source behind underbite and misaligned upper and lower teeth. The specially designed exercises strengthen the facial muscles in the jaw and neck area, granting you more control over your lower jaw and pushing the upper jaw forward.

    Resting the tongue on the upper jaw expands the maxilla, allowing more space for your teeth. It will make a place for crooked teeth to arrange in line and improve overall facial symmetry.

    Mewing and Overbite

    Can mewing correct overbite? Without a doubt, it can! Mewing helps relieve the symptoms of all problems regarding your bite and misaligned teeth. By strengthening the facial muscles, you get more power to push the jaw forward and align the upper and lower teeth.

    Also, people practice mewing with crossbite and open bite problems as it is a unique way of improving jaw position and movement without jaw surgery.

    Mewing and Bruxism

    Can mewing fix bruxism? Let’s answer this by going into more detail.

    Teeth grinding or bruxism is caused by misaligned jaws and bite problems. Mewing addresses jaw issues first, leading to the resolution of many other health issues – including bruxism.

    With proper jaw alignment, the chances of having your teeth clash and chip are largely reduced. Also, learning the correct mewing teeth position will help with all types of bite problems and, consequently, bruxism.

    Mewing and Braces

    You can practice mewing with braces on because it doesn’t interfere with maintaining proper tongue posture. You may experience discomfort if your tongue touches metallic braces constantly, but that should not stop you from following the workout routine designed by

    How Long Does It Take to Get Rid of Underbite While Mewing

    Mewing requires persistence and everyday practice of the technique to achieve the desired outcome. With some aesthetic or health issues, it can take longer to see results depending on age and the severity of the condition.

    More immediate results are achieved in children and pre-teens when dealing with types of bite problems.

    How to Prevent Underbite Recurrence

    Turn mewing into a life-long practice and adopt the resting tongue position as a natural way of placing your tongue. You will be able to retain the results of mewing and enjoy the new and improved you forever!

    Avoid these mewing mistakes, and you’ll never see your underbite return.

    Other Underbite Treatments

    Different treatments for underbite and bite problems can add to the success of the mewing underbite exercises:


    Braces and elastics are popular ways to help align your teeth. You will need to wear them for several years, but braces can help fix all bite issues. Plus, they are a great addition to mewing!

    Clear Aligners

    Clear aligners are custom-molded to fit tightly over your teeth. They can be removed when eating and have become a more popular alternative to braces because of other comfort and aesthetic advantages.

    Reverse-pull Face Mask

    The reverse-pull face mask is recommended for children under 10 as it is effective before bones in the head become fused. It wraps around the chin and pulls the jaw upwards and backward.

    Teeth Extraction

    In cases of a crowded jaw, it is recommended to extract teeth to create more space for them to be pulled back by other underbite treatments.

    Reshaping Teeth

    Reshaping and bonding teeth can downsize them so as not to protrude over the upper jaw. Also, dental crowns can be used to modify teeth’ shape to fall into place and not cause bite problems.
