What is buckteeth? What kind of symptoms do you have?

Buckteeth are a cosmetic feature.

It is also called upper and lower jaw protrusion, beak deformity, protruding jaw deformity, etc.

It refers to the protrusion of the upper and lower incisors and the upper and lower jaws, and the upper and lower lips are often unable to close naturally when relaxed, and a large number of gums are exposed when laughing.

The lips are open and the teeth are exposed, the nasolabial folds are deep, and the facial contour line is excessively protruding forward on the lips when viewed from the side""shape appearance.

In severe cases, the teeth may become blackened, yellowed or even cracked due to long-term exposure.

This characteristic is mostly thought to be related to genetic and congenital factors, but it is not dominant in childhood, begins to manifest in adolescence, gradually becomes obvious with growth and development, is basically stable in adulthood, and is often more significant after middle age due to soft tissue and atrophy protrusion.

The main symptoms of buckteeth are as follows: 1. Exposed nostrils: the habitual masking action of facial expression, the nostrils are forced to pull down, and the nostrils will be mistakenly thought to be exposed.

2. The nose is short and crooked: the foundation is uneven, the bite is not correct, and the development of the nose will be hindered by the palate, of course, it is common to have a long crooked.

3. Thick lips: protruding teeth need to be covered thickly.

4. The chin is retracted, due to the stunted development of the chin.

5. The face shape is short and wide: due to the poor overall development of the middle and lower faces, it has to progress horizontally.

6. Masticatory muscle hypertrophy: Improper bite may cause abnormal force of masseter muscle.

Buckteeth, medically known as "deep coverage", refers to the maximum horizontal distance of more than 3 mm from the incision of the upper anterior teeth to the labial surface of the lower anterior teeth. Patients with "buckteeth" often present with open lips and teeth, smiling and toothy, often accompanied by mandibular recession, maxillary protrusion or maxillary protrusion, lip tilt of upper and lower anterior teeth in the mouth, and often accompanied by crowding and unevenness.

Genetic factors: Asians belong to the Mongolian race, and the face shape is slightly convex, which is manifested in the relatively large amount of teeth in the upper arch or maxilla, and the underdevelopment of the lower jaw or the small amount of teeth in the lower arch.

Bad oral habits: such as mouth breathing, thumb sucking, and biting the lower lip, etc., can cause the upper front teeth to protrude or the lower jaw to retract.

Periodontal disease: Periodontal is the soil of the teeth, and when periodontal conditions are bad, the teeth will show loosening, and even the upper anterior teeth will fan forward in a pattern. Consultation.

？Buck teeth are mainly manifested as protruding anterior teeth, the upper row of teeth protruding a lot, and the lips cannot be closed, which is a condition that greatly affects the aesthetics of the teeth. There are two main types of causes of buckteeth: genetic factors and environmental factors, and the following is an introduction by experts.

Local disorders in the replacement phase, with buck teeth. If there is congenital loss of lower anterior teeth or premature loss of mandibular deciduous molars due to various reasons, the anterior segment of the mandibular arch can be smaller, and the upper jaw can be significantly longer and protruding; Abnormalities in maxillary hyperplasia and the eruption sequence of permanent molars in the replacement phase can also lead to enlargement of the maxillary arch, resulting in the formation of a maxillary protruding bucktooth foramen. Buckteeth are also related to the following two factors.

1. Studies of genetic factors have shown that the upper teeth of this type of patient are disproportionately larger than the lower teeth. In addition, excess teeth in the upper anterior tooth area, which are genetically controlled, and congenital loss of lower anterior teeth can also lead to buck teeth. Severe skeletal deformities, such as underdeveloped jaw and large maxilla, are also influenced by genetic factors.

2. Environmental factors 1. Systemic factors: nasopharyngeal diseases, such as chronic rhinitis, adenoid hypertrophy, etc., cause the upper airway to narrow and replace it with mouth breathing, and gradually form mouth breathing habits. Prolonged mouth breathing can result in narrowing, protrusion, and arch of the palatal arch, which eventually manifests as buckteeth.

2. Local factors: including bad oral habits and tooth replacement disorders. Some bad oral habits, such as long-term thumb sucking and biting the lower lip, can cause the upper front teeth to be tilted outward, crowded, the front teeth protrude, and buck teeth; The development of deformity can be exacerbated by the habit of covering the lower lip secondary to buckteeth.

The above is the introduction of what is the cause of buckteeth, although buckteeth do not have normal tooth function, but it has a great impact on a person's appearance, patients and friends must pay attention. Understanding the causes of buck teeth is the best way to prevent them.

Hello, Joe Slevin, MD of California, USA, said that sleeping on the left or right side all the time can squeeze the tooth bone and face, resulting in asymmetry in the development of teeth and face. Severe dental irregularities can mean "overbiting" or "buckteeth" or even facial deformities. Normally, the teeth should be aligned in a natural way, but if not aligned properly, the pressure of chewing can damage the teeth, worsening the situation.

In addition, misbites can lead to migraines. If you correct the direction of the bite and improve the bite, the pain usually goes away.
