2. Causes: Tracing the Origins
What causes an overbite? A plethora of reasons can be attributed to this condition. Genetics stands out as the leading cause. If parents or grandparents had overbites, chances are higher that the next generation might exhibit the same condition. However, genetics isn’t the sole contributor.
Certain childhood habits can also instigate or worsen an overbite. Prolonged thumb sucking is a prime example. Kids who suck their thumbs past the toddler years might exert pressure on their front teeth, pushing them outwards. Similarly, excessive pacifier use or constantly pressing the tongue against teeth can pave the way for an overbite. Each of these habits can subtly alter teeth alignment over time.
Overjet has its set of reasons. Genetics, as with overbites, play a significant role. If there’s a family history of overjets, it can manifest in the subsequent generations. But the story doesn’t end with genetics.
Various habits can exacerbate the condition. Thumb sucking, as mentioned earlier, not only affects overbites but overjets too.
The constant pressure against the upper teeth can cause them to jut out horizontally. Another habit to consider is tongue thrusting. Some individuals, often unknowingly, push their tongue against their upper teeth, especially when swallowing. (2)
