Proclined teeth/Prognathic upper jaw is a situation in which the upper teeth or the upper jaw is protrusive (forwardly placed) in relation to the other facial structures due to relatively larger size teeth/jaw or anterior positioning of the jaw. It's typically caused by genetics, bad oral habits like thumb sucking, mouth breathing or overdevelopment of the bone that supports the teeth.
Overly crowded(Crooked Teeth)
Teeth crowding occurs when there is simply a lack of room within your jaw for all of your teeth to fit normally. When left untreated, overly crowded teeth can get worse over time, and result in severely crooked teeth. This crowding can lead to plaque accumulation, tooth decay and an increased chance of gum disease.
Gaps between teeth can occur with abnormal continued growth of the jawbone. Missing teeth can also cause the surrounding teeth to shift due to the extra space, creating gaps in your teeth. Spacing issues and gaps between teeth can lead to gum problems (due to lack of protection by the teeth), periodontal pockets and increased risk of periodontal disease.
What people commonly refer to as an "overbite" is known to dental professionals as "Deep bite" It occurs when the upper teeth bite over the lower teeth excessively. It's typically caused by genetics, bad oral habits, or overdevelopment of the bone that supports the teeth. This can lead to gum problems or irritation, and/or wear on the lower teeth, and can cause painful jaw and joint problems.
Underbite can occur when the lower teeth protrude past the front teeth. It's usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by missing upper teeth. This can prevent the normal function of front teeth or molars, which can lead to tooth wear. It can also cause painful jaw and joint problems
Open bite often occurs when some teeth are unable to make physical contact with the opposing teeth for a proper bite. Most often caused by a genetic abnormal jaw structure or excessive thumb-sucking, an open bite can cause poor or painful chewing, and even speech impairment. It can also lead to greater issues like Tempromandibular joint(TMJ) disorder.
Misaligned dental midlines
Cross bite can occur when the upper and lower jaws are both misaligned. It causes one or more upper teeth to bite on the inside of the lower teeth, and can happen on both the front and the sides of the mouth. This can cause wear of the teeth, gum disease and bone loss.
