Note the agenesis of the maxillary lateral incisors and the second premolars, the retained primary mandibular molars, the generalised spacing, and the deep bite. Within the tooth bud, there is a collection of cells, the primary enamel knot, and these cells manage this process via signalling proteins. Infertility is "a disease of the male or female reproductive system defined by the failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse." 1 According to the CDC, approximately 12% of women aged 15 to 44 years (regardless of marital status) have difficulty getting pregnant or carrying a pregnancy to term.

Hypodontia is the most common craniofacial malformation in humans, as it may occur as part of a recognised genetic syndrome or as a nonsyndromic isolated trait. For example, maxillary lateral incisors develop in the region where the lateral maxillae and medial nasal bone processes fuse, while the mandibular second premolars originate in another delicate region [44]. Hypodontia can have a marked psychosocial effect and functional implications for a growing child. In addition, microdontia is genetic and presents in its severest form as ectodermal dysplasia [24].

If you are born with lesser teeth than an average person, you have hypodontia. Meanwhile, treatment of hypodontia patients often takes a number of years, from their initial visit through to completion of treatment. Other features include smaller maxillary and mandibular lengths and a Class III skeletal relationship tendency [35]. 371375, 1994. It is therefore plausible that hypodontia may pose functional limitations that affect an individuals general well-being and quality of life in the process, although there is currently limited evidence to support this. 551556, 2001. Twin and family studies have determined that agenesis of lateral incisors and premolars is inherited via an autosomal dominant gene, with incomplete penetrance and variable expressivity [7, 8, 13, 32, 4952]. The most common reason could well be genetics, which means it may simply have been in your family. Don't worry, we won't share your email with any third parties.
