Dr. Paula Munarriz Explains Orthodontic Treatment for Deep Overbite At 3Dental
- Orthodontic TreatmentsDr. Paula Munarriz Explains Orthodontic Treatment for Deep Overbite At 3Dental
- Orthodontic TreatmentsA deep overbite is a type of bite misalignment (also called a malocclusion) where the upper front teeth overlap the lower front teeth by more than one-third.
In severe cases, the lower teeth may even touch the gums or the roof of the mouth behind the upper teeth.
This excessive vertical overlap can affect chewing, speech, jaw comfort, and overall oral health.
A deep overbite is one of the most common orthodontic issues, affecting around 20% of the population.
Many people are unaware that this condition can have a significant impact on their oral health if left untreated.
An overbite happens when the upper teeth overlap the lower teeth.
A small overlap is normal, but ideally it should cover no more than one-third of the lower teeth.
When the overlap is greater, it can lead to dental complications over time.
In this guide, the orthodontists specialist at 3Dental explain the symptoms, causes, and orthodontic treatment options for deep overbites, helping patients understand why early diagnosis and orthodontic care are important for long-term dental health.

- InvisalignA deep overbite can usually be identified during a dental exam, but there are several signs you may notice yourself.
Common symptoms include:
- Upper front teeth overlapping the lower teeth by more than one-third.
- Backward angulation of the upper front teeth.
- Jaw pain or discomfort in the temporomandibular joint (TMJ) can sometimes lead to tension headaches.
- Difficulty chewing food properly.
- Speech issues caused by incorrect tongue placement.
- The appearance of "buck teeth."
- Sleep apnea, as the tongue is pushed back and narrows the airway.
In addition to these physical effects, a deep overbite can also impact confidence.
Many patients feel hesitant to smile, which makes treatment important not only for oral health but also for self-esteem.
Potential Dental Issues Associated With Deep Overbites
An overbite isn’t only a cosmetic concern — it can also create oral health complications if left untreated. Some of the most common issues include:
- Excessive wear on the front of the lower teeth and the back of the upper teeth.
- Gum irritation or injury occurs when the lower teeth press into the upper gums. Over time, this can increase the risk of gum disease and even tooth decay.
If not addressed early, these problems can worsen and become more complex to treat.
Anyone experiencing these symptoms should have their bite assessed by a dentist or orthodontist to protect their long-term oral health.
Dental Treatments for Deep Overbite
The best treatment depends on factors such as severity, age, and whether other dental issues are present.
At 3Dental, we offer a range of tailored solutions designed around each patient’s specific needs.
| Treatment | Description |
|---|---|
Bite plates | For children with mild cases, bite plates or similar appliances can guide teeth into a healthier position. They are non-invasive and easily incorporated into daily life. If you suspect your child has a deep bite, early assessment is key — timely intervention prevents complications as they grow. |
Braces | For teenagers and adults with moderate cases, braces are often the most effective option. By gradually moving the upper and lower teeth into alignment, braces correct the bite and improve both function and appearance. Treatment may take time, sometimes years, but the results are long-lasting. |
Aligners | In some cases, clear aligners can be used to correct bite issues. They are often preferred for their discreet appearance, though braces are usually more effective for moderate to severe overlaps. Your dentist or orthodontist will advise whether aligners such as Invisalign are a suitable option. |
Surgery | Corrective jaw surgery, also known as orthognathic surgery, may be necessary when the overlap exceeds five to six millimetres or when skeletal factors are involved. Surgery is typically combined with orthodontic treatment for the best outcome and is only recommended as a last resort. If required, your dentist will explain all options and potential risks in detail. |

What Causes Crowded Teeth?
There are many potential causes of crowded teeth. Let's take a look at the most common risk factors:
| Risk Factors | Description |
|---|---|
| Genetics | One of the leading causes of a severe overbite is genetics. Just as we inherit eye colour or face shape, we also inherit jaw size and tooth alignment. A smaller lower jaw, for example, makes it easier for the upper teeth to overlap too much. If one or both parents have jaw alignment issues, there is a higher chance their children will experience the same. |
| Childhood Habits | Early habits can affect how the bite develops. These include: - Thumb sucking - Prolonged use of dummies - Tongue thrusting during swallowing Such habits put pressure on the upper teeth and can gradually change the bite. If they continue past early childhood, they often result in a deeper overbite that may later require orthodontic treatment. |
| Dental vs Skeletal Issues | In many cases, an overbite is primarily a dental issue caused by tooth positioning. More severe cases, however, may involve skeletal problems linked to the relationship between the upper and lower jaws. Skeletal causes are more complex and may require a combination of orthodontic treatment and corrective surgery. |
| Wear and tear over time | Even a mild overbite in childhood can worsen with age. As enamel gradually wears down, the bite deepens, sometimes leading to gum irritation and other complications. |
No matter the cause, the team at 3Dental will carefully assess whether your case is dental, skeletal, or habit-related and recommend the most effective treatment plan.Dr. Paula Munarriz
