4 Most Unusual and Rare Dental Conditions

Our mouth is the smallest part of our body. However, it is one of the most complex structures containing many elements and tissues that play an essential role in the proper functioning of the mouth.

Some of the key players of the mouth are our teeth like incisors, canines, premolars, molars, and supporting tissues like gums and oral tissues.

Ideally, a child consists of 20 primary teeth, and an adult consists of a set of 32 permanent teeth. However, in some rare cases, the number may vary due to anomalies that may develop in the mouth.

It is always better to get a routine dental check-up, especially for children by the age of seven. The dentist is the best professionals to determine dental health and teeth problems.

Some of the common malocclusions or changes in dental tissues may be corrected by orthodontic interception.

In rare instances, children may also show signs of some unusual and uncommon dental issues. Some of them are anodontia or hypodontia, talons cusp, germination, and supernumerary teeth.

Presence of such dental anomalies may affect the occlusion of the individual. So, what exactly do these anomalies entail? Let’s find out more in this article.

Rare dental conditions

I am going to discuss four unusual and unheard dental anomalies.

Anodontia/Hypodontia

Anodontia is a rare genetic condition. In this condition, the individual may be missing all of the permanent teeth due to the inability of the permanent tooth buds to develop.

Usually, the primary teeth are not affected by anodontia. However, a child with anodontia will most probably never have a set of permanent teeth after the primary teeth fall out. Often children with this condition also suffer from ectodermal dysplasia. (1)

An alternative state of anodontia is oligodontia. The nonexistence of one diagnoses this condition to six teeth in the mouth.

Treatment of anodontia typically requires placement of implants or dentures. The procedure is started as soon as all the primary teeth fall out to maintain the self-esteem of the child and help him in eating, speaking, and breathing.

Talons Cusp

Talons cusp is a unique outgrowth of enamel that develops on the back of the incisors or canines. It looks like a claw and is often compared to an eagle’s talon. (2)

In most of the cases, talon’s cusp is left unnoticed. However, in some instances, talon’s cusp can cause tooth problems –

  • Malocclusion or problem in bite
  • Crowding of the mouth which may complicate the eruption of other teeth
  • Irritation to gums, cheeks, and tongue
  • Plaque accumulation in the groove between the cusp and the tooth

Commonly, the treatment involves cusp contouring, which grinds down the tooth structure. If the cusp contains pulp, the dentist may recommend root canal treatment. (3)

Gemination

Tooth gemination is a similar condition as tooth fusion. In this condition, two teeth develop from a single tooth bud. The result is a large, disfigured tooth with two crowns with separate pulp chambers but they share a common root.

Common problems that may occur due to the geminated tooth are –

  • Bad bite
  • Tooth decay especially in the co-joined area of the pulp chamber
  • Overcrowding of the teeth
  • Delayed eruption of the adjacent teeth

Most of the times, the tooth is left untreated unless it causes a problem in occlusion. Otherwise, the dentist may extract the tooth. (4)

Geminated tooth cannot be flossed. So particular emphasis is given to oral health care in such patients.

Supernumerary tooth

Also called as hyperdontia, this condition is recognized by the development of extra teeth other than the permanent natural teeth.

Often, supernumerary teeth may not erupt instead may develop in the gum and delay the eruption of the underlying tooth. Having an extra set of teeth also overcrowds the mouth. (5)

The best treatment for supernumerary teeth is to extract them. Although orthodontia may also be an acceptable course of treatment in specific cases.

Take away message

Sometimes, the tooth may develop anomalies that may affect the occlusion. In this article, we have discussed four of the unusual tooth anomalies.

Anodontia is a genetic condition in which all the permanent teeth fail to develop. Treatment involves the replacement of teeth with implants and dentures.

Talons cusp is an enamel overgrowth mostly found on the back of the anterior teeth. Usually, it doesn’t cause any problem, but in cases of malocclusion, the cusp may be ground.

Geminated tooth is a unique variety in which two crowns develop from a single tooth bud. This condition may overcrowd the mouth, so usually, it is extracted.

Supernumerary teeth are an extra pair of teeth that most commonly are the reason for overcrowding of the mouth. The standard treatment involves extraction.

With the knowledge of these four anomalies, you can consult your dentist immediately and get the necessary treatment.
