Hello! Today, Dentajoy has another piece of useful dental knowledge to share with you. Let’s dive right into the topic.
One of the most common questions patients ask our orthodontists at Dentajoy is about their upper teeth covering the lower teeth completely when they bite down. This condition is called a Deep Bite.

What is a Deep Bite?
A Deep Bite is a type of malocclusion in which the upper front teeth excessively overlap the lower front teeth, to the point where the lower teeth are almost invisible when biting. This condition not only affects your smile but can also harm your oral health, causing issues such as tooth wear, gum injuries, root damage, and even loose teeth.
Causes of Deep Bite
1.Genetics – Some people inherit the tendency for a Deep Bite from their parents or family members.
2.Childhood habits – Prolonged thumb sucking or pacifier use can affect the bite.
3.Abnormal jaw growth – For example, when the lower jaw is smaller than the upper jaw, leading to improper tooth alignment.
4.Tooth loss – Premature loss of certain teeth, especially molars, can contribute to a Deep Bite.
Consequences and Risks of a Deep Bite
1.Tooth wear – Continuous friction can cause the enamel to wear down. If left untreated, the wear may extend into the pulp, requiring root canal treatment.
2.Gum problems – It may cause gum recession, injuries, or gum inflammation.
3.Root damage – Constant traumatic contact can lead to root inflammation.
4.Shorter facial appearance – A Deep Bite can make the lower third of the face look shorter due to the incorrect bite position.
5.Speech difficulties – Some sounds may be harder to pronounce correctly.
How to Treat a Deep Bite
1.Regular dental visits – Early checkups allow dentists to detect and treat the problem before it worsens.
2.Orthodontic treatment – Braces or clear aligners are the main methods to correct the bite and reposition the teeth.
3.Jaw surgery – In severe or complex cases involving jawbone discrepancies, surgical correction may be required alongside orthodontics.
Can Orthodontics Correct a Deep Bite?
Yes, orthodontic treatment can successfully correct a Deep Bite. However, the outcome depends on the cause and severity of the case. Our orthodontists at Dentajoy will carefully assess each patient and design a personalized treatment plan. Options may include metal braces, clear aligners, or—in cases of skeletal issues—orthodontics combined with jaw surgery. The goal is to achieve proper bite alignment and restore a confident smile.
