- Amelogenesis imperfecta - A condition in which enamel does not form properly or at all.
- Dentinogenesis imperfecta - A condition in which dentin does not form properly and is sometimes associated with osteogenesis imperfecta.
- Dentin dysplasia - A disorder in which the roots and pulp of teeth may be affected.
- Regional odontodysplasia - A disorder affecting enamel, dentin, and pulp and causes the teeth to appear "ghostly" on radiographs.
Tooth size abnormality
- Microdontia - A condition where teeth are smaller than the usual size.
- Macrodontia - When teeth are larger than the usual size.
Teeth number abnormality:
- Anodontia - The total lack of tooth development.
- Hyperdontia - The presence of a higher-than-normal number of teeth.
- Hypodontia - The lack of some teeth. Usually:
- Hypodontia - Refers to the lack of development of one or more teeth
- Oligodontia - May be used to describe the absence of 6 or more teeth.
Teeth shape abnormality
- Fusion of two deciduous teeth.
- Gemination - Occurs when a developing tooth incompletely splits into the formation of two teeth.
- Fusion - The union of two adjacent teeth during development.
- Concrescence - The fusion of two separate teeth only in their cementum.
- Accessory cusps - Additional cusps on a tooth and may manifest as a Talon cusp, Cusp of Carabelli, or Dens evaginatus.
- Dens invaginatus, also called Dens in dente - A deep invagination in a tooth causing the appearance of a tooth within a tooth.
- Ectopic enamel - Enamel found in an unusual location, such as the root of a tooth.
- Taurodontism - A condition where the body of the tooth and pulp chamber is enlarged.
- Hypercementosis - Excessive formation of cementum, which may result from trauma, inflammation, acromegaly, rheumatic fever, and Paget's disease of bone.
- Dilaceration - A bend in the root which may have been caused by trauma to the tooth during formation.
- Supernumerary roots - The presence of a greater number of roots on a tooth than expected.

Quick Facts: Dental
It's important to take care of your mouth and teeth starting in childhood. If you don't, you could have problems with your teeth and gums, like cavities or even tooth loss. How to keep your mouth and teeth healthy:
- Limit sugary snacks.
- Don't smoke or chew tobacco.
- See your dentist or oral health professional regularly.
- Brush your teeth every day with a fluoride toothpaste.
- Clean between your teeth every day with floss or another type of between-the-teeth cleaner.
Chewing gum assists oral irrigation between and around the teeth, cleaning and removing particles, but for teeth in poor condition it may damage or remove loose fillings as well. Chewing sugar free chewing gum that contains xylitol may be good for teeth. Dental chewing gums claim to improve dental health. Sugar-free chewing gum stimulates saliva production, and helps to clean the surface of the teeth.
