When top teeth stick out | Overjet causes & treatments

Do your top teeth stick out?

If your top teeth stick out or you’ve been told you have an overjet, don’t worry. This simply means your upper front teeth sit further forward than your lower ones. This is very common in adults and is something we assess regularly at Smileworks. Overjets are treated with braces, and our dentists and orthodontists help patients achieve balanced, natural-looking smiles every day.

Should I be worried about an overjet?

Overjets are usually straightforward to treat, but if left unmanaged they can be associated with certain aesthetic and clinical concerns. These are things your dentist will discuss with you during a consultation.

Aesthetic concerns (confidence and smiling)

People whose teeth stick out often feel self-conscious about their smile. Many avoid smiling in photos or feel uncomfortable relaxing their lips. Patients frequently describe braces treatment for an overjet as life-changing because these concerns often disappear once the teeth are brought into balance. Dr Eduardo says, “many patients say their teeth make them feel awkward. So they come in for an assessment and we help them.”

Clinical concerns (trauma, oral health, speech and chewing)

Patients with an overjet of more than 4mm are at a higher risk of dental trauma, as protruding front teeth are easier to knock or chip. In more pronounced cases, closing the lips comfortably can be difficult, which may lead to a dry mouth. Saliva plays an important role in protecting teeth and gums, so this can increase the risk of decay or gum problems over time.

In some patients, a larger overjet can affect speech. Sounds that rely on the front teeth and lips may be less clear, and a mild lisp can develop. This is common and entirely treatable with orthodontic care.

A pronounced overjet can also make biting and chewing less efficient because the front teeth do not meet as they should. This can place extra strain on the teeth and jaw and may lead to discomfort when eating.

Not all overjets require treatment. Whether braces are recommended depends on the size of the overjet, how your teeth meet, and whether it is affecting appearance, function, or long-term tooth health. All of this is discussed during a braces assessment, book yours here. And finally get an expert to tell you precisely what you need.

Overjet definition (the science part)

An overjet is the horizontal overlap of the teeth, meaning the top teeth protrude forward in relation to the bottom teeth. It is often confused with an overbite, which describes a vertical overlap. A simple way to remember the difference is that overjet refers to front-to-back, while overbite refers to up-and-down.

If you’ve been told you have an overbite rather than an overjet, you can read more in our overbite article. Overjets are measured in millimetres, so you may hear your dentist say something like, “you have an 8mm overjet”.

Between 2 and 4mm is considered within a normal range. Larger overjets can usually be treated with braces, but treatment is always based on the individual rather than a single measurement.

What causes an overjet?

An increased overjet can develop for a few different reasons and is often the result of a combination rather than a single cause. Most commonly, it relates to the position of the jaws. The upper jaw may sit further forward than average, or the lower jaw may sit slightly further back.

The number and position of the teeth can also play a role. Missing teeth, particularly in the lower jaw, or differences in the length of the dental arch can allow the upper teeth to move forwards over time.

In some cases, the angle of the upper front teeth contributes to the appearance of an overjet. Teeth that tilt forwards naturally can increase both the look and measurement of an overjet. This may be linked to childhood habits such as thumb sucking, or simply how the teeth developed.

How is an overjet treated?

In adults, an increased overjet is usually treated with braces to bring the teeth into a healthier, more balanced position. The approach depends on how pronounced the overjet is and whether there is crowding or spacing elsewhere in the mouth.

In some cases, creating space is part of achieving a stable result. This may involve removing specific teeth as part of orthodontic treatment. This is a well-established and routine approach when appropriate, and the aim is always a natural-looking, functional bite that is stable long term.

During a consultation, we assess your teeth, bite and jaw relationship before recommending any treatment. Not everyone with an overjet needs the same approach, and some people may not need treatment at all.

Amazing experience and results, Dr Khalid and Jo went above and beyond to make sure I was happy with my results and really looked out for me, I went in for the teeth whitening treatment &cleaning and my teeth are finally white , am now very confident in my smile which is not something I ever thought I’d say. Highly recommend if you’re on the fence, it was definitely worth it.The difference was massive, quick and painless (tiny bit of sensitivity but extremely manageable)

After having a very bad experience with another orthodontic practice in the city, I went to Smileworks to help improve my smile. I had been to Smileworks before and knew I could trust them as I was left feeling devastated with my results from the other practice. I was left with massive gaps after braces from the other practice, my bottom teeth were chipped, and I needed 8 teeth bonding. Paula and Steph have been absolutely amazing through this whole 3 month journey. I have been treated with such dignity and respect, they have been nothing but kind and informative. Paula talked me through my whole treatment plan step by step and explained in-depth what was going to happen at every appointment. I had a thorough hygiene appointment, whitening, and finally the composite bonding that has been life changing for me. I have also been scanned for new retainers! I cannot stop smiling and looking at my teeth. I was a little anxious before my bonding appointment but Paula made me feel very calm by explaining the whole process and offering breaks if needed, she regularly checked on me throughout and it went so much quicker than I expected. It didn’t hurt and wasn’t even slightly uncomfortable. I will continue to go to Smileworks as they have provided me with a service I can trust, after having poor dental/orthodontic experiences I feel so much better that I have found a practice I can trust with fantastic staff. Thank you so much Paula and Steph.

I’ve had a great experience with the Smileworks team – from the receptionists, through orthodontist Eduardo, to my dentist Paula and her assistants. I found everyone to be very professional, kind and helpful.During my first appointments, I had a comprehensive examination, including an orthodontic consultation, where I received fair and honest advice. This ultimately led me to pursue general and aesthetic treatment with Paula, who is an excellent, detail-oriented professional. Throughout the treatment, every step was clearly explained and discussed with me.In the end, I’m very happy with both the results and the overall experience with the practice 🙂
