Adentia: Partial and Complete
Missing teeth are a problem that reduces self-esteem and quality of life. They can cause stomach problems, impaired speech, and facial contour changes.
In dentistry, this condition is called adentia. Timely restoration of the dentition prevents tissue atrophy and preserves the health of adjacent teeth.

Symptoms and consequences of missing teeth
Adentia manifests itself not only as a visual gap in a smile. It is a complex degradation of the dental system.
Mastication and diction impairment
Missing teeth makes it impossible to properly grind food, which leads to gastrointestinal diseases. Furthermore, teeth are involved in the formation of sounds. Their loss leads to a lisp and slurred speech.
Teeth displacement and bite changes
When a vacant space appears in a row, adjacent teeth lose their support and begin to shift, trying to fill the void. This causes malocclusion, the development of interdental spaces (tremas), and increased wear on the remaining teeth.
Bone Atrophy and Aesthetic Changes
The jawbone relies on chewing. As soon as the load is removed, bone atrophy begins. The alveolar ridge shrinks, leading to an "aged" facial appearance: the corners of the mouth droop, the chin protrudes, and deep wrinkles appear.
Signs that indicate you should see a dentist:
- One or more teeth are missing
- Difficulty chewing food
- Pronunciation of certain sounds has changed
- Neighboring teeth have begun to shift
- Facial shape or bite has changed
- Prosthesis is no longer fitting properly
Causes of Adentia
There are many causes of the disease. A dentist makes a diagnosis, and only they can determine the cause of tooth loss.
Congenital Causes
Congenital tooth loss is almost 100% due to heredity, endocrine, and viral diseases of the mother during pregnancy.
Acquired Causes
The main cause of secondary tooth loss is advanced dental caries and its complications (pulpitis, periodontitis). Gum disease, periodontitis, which destroys the ligaments that hold the tooth in its socket, is the second most common cause. Mechanical jaw injuries and unsuccessful surgical interventions also lead to tooth loss.
Risk Factors
- Diabetes, osteoporosis
- Incorrect or infrequent brushing of teeth
- Smoking (impairs blood supply to the gums)
- Age and poor nutrition
- Visiting the dentist less than twice a year
The problem of missing teeth is also relevant in pediatrics. It requires special attention from parents and dentists.
When missing teeth require examination
If baby teeth have not erupted on time, or if permanent teeth take a long time to appear after a baby tooth has fallen out, you should consult a dentist. A delay of more than 4-6 months from the average is a reason for diagnosis.
Specifics of diagnosis and monitoring
If a child's teeth are not erupting on time, it is necessary to check the buds in the jaw. Simply waiting can lead to jaw deformities and bite problems in the future. A dentist will take a targeted or panoramic X-ray to see the teeth hidden in the gums. Only then will it be clear whether the child needs an orthodontic consultation.
General information
Diagnosing Adentia
Before starting treatment for adentia, a comprehensive examination is performed.
Examination and Medical History
The dentist assesses the number of remaining teeth, the condition of the mucous membrane, and the overall level of hygiene. The causes of tooth loss and the presence of systemic diseases are determined.
X-rays and CT scans
Computer tomography (CT) is used to assess the condition of the jaw. It allows for the detection of hidden inflammatory processes, the position of the roots, and, most importantly, bone density and volume.
Assessment of the bite, gum condition, and bone volume
The specialist analyzes how the jaws close and whether there is enough space for the placement of a prosthesis or implant. In some cases, bone grafting may be necessary.
Indications and Contraindications for Dental Restoration
The primary indication is partial or complete tooth loss leading to functional impairment. Contraindications include decompensated diabetes mellitus, bleeding disorders, acute cancer, and acute mental disorders. In each case, the dental surgeon and orthodontist assess the risks individually.
Post-Treatment Care and Adaptation
Any orthopedic device requires care. Removable dentures need to be rinsed, and implants should be cleaned as thoroughly as your own teeth, using an irrigator. Adaptation to the denture can take anywhere from a few days to months.
Preventing Edentulism
Preventing dental defects is easier than treating them. Visit your dentist every six months, treat cavities promptly, and floss after meals. Even if you lose just one tooth, dental prosthetics should be performed as soon as possible to prevent bone loss.

Types of edentia
The classification of the disease is based on the number of missing teeth and the time of onset of the pathology.
Partial edentia
Partial edentia is the absence of one or more teeth in a row. The natural supporting teeth remain on the jaw. This condition often leads to malocclusion, as adjacent teeth begin to lean toward the defect.
Complete edentia
Complete edentia is the complete absence of teeth on one or both jaws. This condition significantly reduces quality of life: a person cannot properly chew hard food, articulation is impaired, and facial features undergo changes due to recession of the lips and cheeks.
Primary and secondary edentia
Primary (congenital) edentia is the absence of tooth rudiments. It's rare and most often caused by a genetic disorder or intrauterine developmental issues.
Secondary (acquired) adentia is the loss of teeth that have already erupted. It's most often associated with trauma and untimely treatment of dental caries or periodontal disease.
