There are many reasons why you get messed up teeth; inherited disorders, abnormal gene, congenital disorder, and environmental. Abnormal genes are caused by abnormal chromosomes. A child can inherit large teeth from one parent and a small jaw from the other parent or the opposite. The things that are environmental are infections, drugs, and exposure to radiation. Pregnant women need to be careful because it can cause birth defects.
The disturbance of the jaw can have macrognathia; is an abnormally large jaw, micrognathia; is small jaw, exostosis; is a benign bony growth that projects outward the surface of a bone; torus palatinus; torus palatinus; is a bony overgrowth at the midline of the hard palate, torus mandibularis is a bony overgrow on the lingual surface of the mandible near the premolar and molar areas.
Cleft lip, cleft palate, cleft uvula, ankyoglossia are deformation caused by abnormal genes when the baby develops when the mother is pregnant. Cleft lip is when the maxillary and medial nasal processes fail to fuse. Cleft palate is when the palatal shelves fail to fuse with the primary palate. Cleft uvula is the mildes form of cleft palate. Ankyloglossia is also known as tongue tie and it happens in the lingual frenum that extends to the apex of the tongue.
Tooth development and eruption are amelobastoma is a tumor composed of remnants of the dental lamina that faild to disintegrate after the tooth buds were formed, anodontia is absence of teeth, supernumerary teeth is excess of the 32 normal permanent teeth, macrodontia is large teeth, microdontiais small teeth, dens in dente is tooth within the tooth. Variation in form may include extra, missing, or fused cusps or anomalies of roots. Hutchinson’s incisors are a variety of peg shaped teeth that are usually associated with maternal syphilis. Fusion is the joining together of the dentin and the enamel of two or more separate developing teeth. Germination is an attempt by
